I'm a doctor - board certified in Internal Medicine. Unfortunately, in over 30 years of practice have seen the occasional disappointing outcome from elective surgery. So when the arthritis in my hip gave out - requiring a hip replacement - I made sure I chose an orthopedic surgeon with excellent training and a record of success. I was impressed after meeting Dr. Ayaz Biviji in his office in Orange. Not only was he clearly knowledgeable, experienced, and capable, his office staff was efficient and competent. My hip surgery went like textbook. It was state-of-the-art CT-guided & robotically assisted. My recovery was fairly swift and uneventful. After a few months with postoperative physical therapy, I returned to my activity regimen. I currently have no pain or difficulty either hiking miles in the hills or just walking around interesting places while on vacation. Recently, my shoulder joint also succumbed to degenerative arthritis - essentially "bone on bone". Because of the excellent results from Dr. Biviji's treatment of my hip, without hesitation I returned to him to discuss options for my shoulder. After trying some ineffective conservative therapy, I elected to undergo shoulder replacement surgery - again CT-guided & robotically assisted - with excellent results. I now have no shoulder pain and normal use of the arm. Without reservation, I highly recommend Dr Ayaz Biviji and his excellent PA, Elizabeth McKinley, if you need orthopedic referral. J.

Dr. Biviji did a quality job on my knee replacement surgery and now I am following up!

Dr. Biviji is amazing. He has performed 2 procedures on me and I couldn't be happier with the results. I highly recommend him and his team!

My experience with Dr. Biviji was absolutely fantastic! Not only has he done my surgery, he did my wife's hip and by 96 year old aunt's double hip and double knee replacement surgeries! Deciding to have total hip replacement surgery was not easy for me, but Dr. Biviji and his team could not have been better! I had a few things to address prior to my surgery, and Dr. Biviji was extremely helpful and supportive along the way. I need to have my other hip replaced, and I'm looking forward to scheduling my next surgery with Dr. Biviji and his team this week. If you're looking to have hip or knee surgery, you can't choose a better surgeon than Dr. BIviji. read more

A Son's Testimony -- Dr. Ayaz Biviji, Orange Orthopedic Medical Group This is for anyone caring for an elderly parent -- anyone who's ever sat awake at night trying to figure out how to help the person who once took care of them. My mom means everything to me. She's my angel, my reason for breathing, and as she's gotten older, she hasn't had anyone else to lean on. Her entire life was spent serving others -- cooking food for people in a trailer park, raising her children as a single mother. And 35 years of that work took everything out of her knees and hands. By the time she turned 75, both knees were bone-on-bone. She could barely walk to the bathroom. Her pain was constant. And as her son, watching that pain became my pain. For more than fifteen years I took her to doctors -- cortisone shots, epidurals, PRP, nerve ablation, even stem cells in Vegas. Every time, I hoped this would be the thing that gave her back her life. Then we met Dr. Ayaz Biviji at Orange Orthopedic Medical Group, through a referral and a prayer. For the past five years, he has taken care of my mom like I imagine he would care for his own mother -- with patience, grace, and humility. Every visit, he listened. Every fear, every question, every cancelled surgery -- he understood. And there were many cancellations. My mom fell and broke her nose. Her leg snapped back. Her blood pressure spiked. Anxiety took over. More than once, we had to cancel right before surgery, and each time, Dr. Biviji and his staff treated us with compassion, not frustration. They never rushed us. They never made us feel like a burden. When the time finally came for surgery -- a total right knee replacement -- I was terrified. My mom is 75, overweight, anemic, has AFib, high blood pressure, and diabetes. But every detail was handled. Dr. Biviji explained everything: the anesthesia, the robotics, the risks, the blood thinners, the recovery. He and his assistant Elizabeth guided us step by step, with a calmness that gave us strength. After surgery, they followed up. They made sure my mom was comfortable, healing, supported. To see my mom finally walk again -- to see her smile through the tears instead of cry through the pain -- changed my life. Dr. Biviji didn't just replace her knee. He restored her dignity. He reminded me that there are still doctors in this world who lead with love and grace, who treat patients like family, and who do their work with quiet excellence and humility. The entire Orange Orthopedic team deserves every star -- every ounce of gratitude we can give. For the first time in years, my mom has hope. And for that, I'll never forget Dr. Biviji or his staff. They changed my mother's life -- and in doing so, they changed Mine. read more

I am 32 and have seen Dr Biviji a few times in the last 11 years for ACL and meniscus surgery. In 2015 he did my ACL reconstruction with a patellar tendon graft. Being 21/22 years old at that time, I was scared not knowing if I was gonna continue to play sports let alone live an active life style for many years to come. Knowing what he has done for me in the past, he was the first and only doctor I wanted to see and consult with. I am now 5 days post meniscus surgery and he has once again done an amazing job. read more

I had a full knee replacement this past week. The office staff is so professional and helpful!!!! Dr. Biviji is the best surgeon in the area!!!! The office answers your phone calls. read more

The team Dr.Biviji has assembled is professional and kind . I feel supported as I am in recovery day 7 for a total arthoplasty for my right hip. I have had a hip replacement on my left side several years ago and this time around I went home the same day of surgery! Best of all I had the equipment, PT support the same day. I am following all instructions and so far my mobilty is increasing and pain is decreasing . I attribute my successful operation to the excellent standard of care. I very rarely write glowing reviews however Dr. Biviji is at another level of surgical skill that is supported by the result of healing and recovery. read more

I was absolutely dreading knee replacement surgery. Dr Biviji has been amazing, from a very small scar to minimal pain, Dr. Biviji and his team supported, educated and took amazing care. My surgery at 8:00 am was out-patient and I was on my way home by 1:00 pm. The aftercare was great. I am at 6 months from my surgery, walking great with no pain. read more

I had total knee replacement. The staff is on the ball. Always professional, kind, and spend time listening to you. Dr. Biviji and P.A. Elizabeth McKinley preformed my Mako robotic knee surgery. I am recovering great! They are an amazing team. They are gifts from God using their talents. Thank you. read more

I was suffering from a torn meniscus that Dr. Ayaz Biviji repaired and cleaned the cartridge. First of all I want to say is he is the best. My surgery was at 12:45, but he started early and I was home that much earlier! The care him and his staff gave me was exceptional. The professionalism you get when you enter the office is, warm, caring, and reassuring. I have two other friends that had hip replacements by him and they couldn't stop raving about him and his staff! I would highly recommend Dr. Biviji and his staff. Thank you Dr. Biviji! read more

Arthroscopic knee surgery went very well. The care received by the doctor, nurses and anesthesiologist was timely; doctor was not rushed and everyone was friendly and informative. Great experience! read more

This is the second total knee I had completed by Dr Biviji. Provided an excellent surgery and patient care. I have known Dr Biviji for over a decade and I went to him because of his remarkable reputation in the field of orthopedics. His office and support staff are also amazing. read more

Great care and professionalism from Dr. Biviji and his staff. I highly recommend their services.

I had bilateral knee replacement back in January 2015. Dr. Biviji is one of the best orthopedic Drs. In Orange County California. My surgery went smoothly and my knees are doing great. read more

In 2009, Dr. Biviji recommended a Hip Resurfacing operation, which was successful. Dr. Biviji told me that I would have more strength and mobility than a standard hip replacement and I should be able get 10-15 yrs depending on the wear and tear on my device. I saw Dr. Biviji 14 yrs later, August 2023 whereby he told me that my device showed no wear and tear and that it could last me another 20 yrs. Yay! read more

I was referred to Dr. Biviji, by my primary care Doctor. My issue was a tendon injury, in the groin area. I checked in and they sent me for x-rays. I returned and the Doctor came into the room. I was going to show him where my injury was. He said, no, no, just lay on the table. He had me move my left leg two different directions and asked if I had any pain. I sad " no". He declared that I had a hip Flexor injury. He said he was going to order a cortisone injection and walked out the door. So, the visit was about two minutes. No questions about where my pain was, how I hurt it and how long. I got the injection and it didn't work at all. I returned after 6 weeks and an assistant ordered an MRI. I returned several weeks later, and he walked in and declared that I had arthritis in my left hip and offered another cortisone shot. I said no. I have no pain in my hip. I went to a chiropractor/sports medicine Doctor. He found that my left gluteus Maximus was tied up in a huge knot, pulling the tendon up and away from where it should be. He released the knot and I realized I was walking slightly bent over for months. The tendon was pulled out of position for 8 months and I feel some improvement each day, by doing certain exercises. I'm sure Doctor Biviji is a great suergon, as others have noted, but how do you pull diagnoses out of thin air, without ever talking to the patient? I am a very disappointed patient and I will never go back there again. read more

I have been taking family members to Dr. Biviji for over 10 years. He has seen and treated my children and mother. As a practicing physician in Radiology, I trust his exam, assessment and treatment. I work with physicians in all specialties everyday, including orthopedic surgeons. There is definitely a wide range of compassion and sincerity in the way various physicians practice. Dr. Biviji truly cares about the health and recovery of his patients. He is methodical in his approach and subsequently I have always had superior outcomes for my family. He maintains a current knowledgeable practice. He is trustworthy for your orthopedic concerns. read more

I was referred to Dr. Biviji from a close friend when my husband broke his knee a few months ago. I am impressed how quickly my husband has recovered after receiving care from Dr. Biviji and his staff. The office is extremely organized, clean, and the staff are professional. Even though their practice is busy, we have never waited more than 10 minutes to see the doctor. I highly recommend Dr. Biviji to anyone who needs a reliable orthopedic specialist. Thank you Doctor Ayaz Biviji! read more

Sorry for the long story here.... Was having some severe hip pain. Met with Dr. Biviji on November 26. Xrays showed loss of cartilage and an impending hip replacement. Dr. recommended a cortisone shot, and to see him again in 6 weeks - but, if I needed anything before then, to call him or set an appt. The cortisone shot helped, but wore off after about 3 weeks. I was back in severe pain - one of the worst I'd experienced, ever. On December 19th, I called his office to see if he could prescribe pain meds. Left a message and received a return call later in the day from his assistant Pratik, who told me he would connect with the doctor and call me back. One week later, I had not heard anything. I checked with my pharmacist who said they had not received any notice or communication from Dr. Biviji or his office. On Dec. 26th I called the Dr. again. Again left a message, asking for a status on getting a prescription. Received a return call from Pratik late the same day. Here's how the conversation went: Pratik: "As I told you, the doctor is out on vacation." (He never told me that). Me: "Is there another doctor on site who could possibly prescribe something?" (I'd had a previous experience at this office, where another doctor was able to prescribe me something when my attending doctor was unavailable). A pause. "No, all the doctors are on vacation". Me: "How about Eric the Physician's Assistant. He's prescribed meds for me before. Can he help?" Another pause. "Eric is on vacation too". Me: "You're telling me that every doctor in your office (there are I think 5 doctors in this group), including the PA, are all on vacation?" "Yes". Me: "Is there no way to reach Dr. Biviji?" "I've sent him a message and he has not responded. He'll be back in the office on January 2nd". Since I live close by, the very next day, Dec. 27th, I went in to the office to speak to the front desk. The waiting room was full of patients going in to see doctors. Meaning, either every doctor all returned from vacation that day, or something was hinky in my discussion with Pratik. Dr. Biviji was still on vacation. The receptionist at the front desk (a very nice person) told me that only Dr. Biviji can prescribe for me. No other doctor can prescribe if it is not their patient. She said she'd send a message to Dr. Biviji to try and get me a script. Another week. No response. I get that this is in the middle of the holidays, but c'mon - I'm a patient with severe pain looking for help. You'd think at least someone would make an effort. And, he was the one who told me to call him if I needed anything. Jan. 2nd, the day he was to return, came and went. No contact, message, prescription, or call back. I finally made an appointment with a different doctor, who saw me the very next day. Same diagnosis. Scheduled the surgery, and received some pain meds to help me in the meantime. I then canceled my follow-up with Dr. Biviji. I'll now be having my surgery with this new doctor who I really liked. Dr. Biviji, and the entire office, has lost my business. I'm sure not a big deal, he's rich and they have a ton of patients. And guess what - just today I get meds in the mail from Dr. Biviji. He finally put in a prescription on January 9th. 3 weeks after I first called asking for help. Too little too late. I really recommend this new office, Orthopaedic Specialty Institute, on Main St. in Orange. Had a great experience. Wonderful folks in the office, a very nice assistant, and a very attentive and pleasant physician. read more

Dr Biviji puts the patient's interest first. I tore my rotator cuff and saw Dr Biviji. I was fearing the worse, I had read how painful the recovery is from this surgery. He actually advised against surgery and recommended physical therapy instead. I am so glad that he did, because my problem was solved without surgery. My shoulder feels great despite being torn. Dr Biviji made the right call. He is not one of those doctors who unnecessarily will rush you to surgery, as so many of them do. Thank you Dr Biviji! read more

Dr. Bivijii might be a good doctor, but I'll never know. I went for my appointment at 1:30pm and waited for the office to open their doors after lunch. There were 6 people who signed in ahead of me. All of them were scheduled for 1:30pm appointments. I waited 1 hour until 2:30 PM. When I finally expressed concern that I may have been forgotten (as a nurse came to get yet another patient that had come in after me) she said that there had been an emergency and that the doctor likes to take time with his patients. It didn't explain taking the patients in after me, but I was willing to be more patient if there was an emergency. Finally, at 3pm, an assistant comes and gets me. No apology. No "thank you for waiting". I'm escorted into the room asked a few questions and told the that the doctor will be right in. At 3:35pm, when the doctor still hadn't showed, I got up and walked out. Having to wait for 2 hours is ridiculous, regardless of the circumstances. And then, not even the courtesy of an apology. read more

Dr. Biviji performed my left knee replacement surgery in March 2020, and my reverse left shoulder replacement surgery in February 2021. I am very happy with the outcome of these surgeries and have fully recovered. I highly recommend him! read more

I was referred to Dr. Biviji by my primary care physician who told me I had a wrist fracture and needed it set in a cast. I was finally able to get in to see Dr. Biviji after being in pain for almost two weeks. Fortunately, his office has an in-house radiology lab and was able to do x-rays on the spot. During my consultation with Dr. Biviji, he stated that he could see no fracture. However, he did state that I had a torn scapholunate ligament and two separated carpel bones, which turned out to be accurate. He said that I probably needed surgery but that he was not a hand specialist. He recommended "his friend," Dr. Taleisnik, with whom he happened to share the same office. I was desperate to have my hand fixed, and agreed to let him set up an appointment for the following Monday. Over the weekend, I had time to ponder surgery and read reviews of Dr. Taleisnik. Upon reading reviews, I decided that I did not wish to see Dr. Taleisnik. I spoke with a couple of individuals who had great success with another doctor, Dr. Paul Dinh. I decided to cancel my appointment on Monday with Dr. Taleisnik and ask for another referral from my primary care physician to see Dr. Dinh. I was told by the office of my primary care physician that, because of my HMO, I was already referred to Dr. Biviji, and they couldn't change that. I would have to ask Dr. Biviji for another referral. I did just that. When I called to cancel my appointment with Dr. Taleisnik, I asked Dr. Biviji, in a phone message, that I would like to get a referral to Dr. Dinh instead. In an hour or so, I received a call from Dr. Biviji's assistant, and here is the main reason for this single star review. I answered hello, and Dr. Biviji's assistant bypassed the usual polite introduction and went directly to railing at me for wanting to change my referral, questioning me as if I were a criminal on the witness stand, saying he may not be able to give me a new referral and threatening me that it may take a month. I have worked with some pretty rough characters in my life, but I don't recall the last time I was spoken to that way...especially from a person in the medical field. It was evil, narcissistic, and certainly unprofessional. There was no way I would ever go to that office again, and I stuck to my wish for a new referral. He hung up on me. Now, to add strange to the bizarre, less than an hour later, he called back. I let it go to voice mail. And in his message, he had the sweetest, most kind disposition, the exact opposite of his former call, and informed me that I had now been referred to Dr. Dinh. Take of it what you will! As a postscript to this madness, when I was able to get in to see Dr. Dinh, I was told that in addition to the torn scapholunate ligament and separated carpels, I had indeed fractured my radial bone, but by then it was too late to set in a cast. read more

4 years ago I dislocated my shoulder and this person was who my insurance covered. I saw him for maybe 30 seconds before getting pushed off to physical therapy and complained he wasn't needing waste my time I think he was around 2 hours late for his scheduled meeting and lacked giving me any real care. He's supposed to be my primary doctor too. Well my shoulders dislocated again and I'm setting up an appointment with him and his office assistant Marlene becomes really rude and has me doing all this running around to set up an appointment. I call my insurance to verify they'd cover it, and call the office back. I'm put on hold for several minutes and she hangs up on me and I call back and ask why she hung up, but she arrogantly asks me if I'm wanting to schedule an appointment. I don't know why, but she didn't want to help me until the insurance called her. I tried explaining that I'll deal with my insurance company and that she just needed to set me up with an appointment but Marlene wanted me wait a month for someone unknown reason. She wouldn't help and kept arguing with me and got really upset with me for wanting to get my shoulder looked per requests of the ER that treated me. I switched Drs to avoid this person and will more than likely transfer to another Drs office these people shouldn't be in practice how Marlene spoke to me wasn't professional it was like a kid telling me I can't get treated when all she had to do was set me up with an appointment read more

I've had 2 broken bones in the past few years due to football injuries. I'm so happy to have treated both incidents with Dr Biviji. He explained things very well and took the time to answer all my questions. His office was very accommodating, especially when I broke my ankle. I was in a lot of pain and after explaining this to his assistant they squeezed me in the next day. Dr. Biviji was always responsive to calls and messages with questions. If I ever break anymore bones (I hope not), I'm definitely coming back to Dr. Biviji's office. read more

There is a drop off and pick up patients area with white curb at front of the 5 story building. Parking is available about half a block away at a multi story parking structure. Parking is validated at the doctors office. Dr. Biviji's office is on the 5th floor, suite 510. There are two large multi stall bathrooms in the hall way leading to the office. In the office there is free coffee for the waiting room patients. You select your own brand and flavor little coffee container and then pop it into the machine and select the size of the cup. The waiting room has large coffee cups. Young lady that escorted my wife (patient) and me to exam room was friendly and cheerful. Exam room consisted of two small rooms. One room had stored items, because it had previously been the Cast room, the other room was a small standard exam room, with a lay down exam bed and one full chair and one stool chair. A little tight. Next came in Heather, who looked up and reviewed our computer data information and revised some information that we gave her. She was friendly and helpful and answered all our questions. We felt she was not "rushed" to get out of the room. She gave us all the time we wanted. Next was the x-ray tech lady, who also friendly and assisted my wife to the x-ray room. Dr.. Biviji came in an explained the x-rays, went over some information, and answered all our questions. Again, we felt he was not "rushed" to get out of the room, as some other doctors we have seen previously at other offices. We felt comfortable with him. We like the staff and the doctor, and will recommend them to our friends and family. The only reason I did not give them a 5 star rating was because of the exam room, other than that , they are a 5 star rating. I am a fan of the staff and the doctor...by the way, he was recommend by one of our friends who had very serious pelvic-hip surgery, and she was happy with the staff and doctor. Our friend now she is walking and driving her car. where before she could not walk unassisted nor drive a car. read more

My knee is completely fixed ! Dr Bivji spent a lot of time going over all the options, advantages and disadvantages, evaluated whether the surgery was needed. The surgery went really well and I would definitely go back to him again for any orthopedic issues. read more

Dr. Biviji is an amazing surgeon with a lot of compassion . Being the caretaker or 2 widowed mom's who needed knee replacements I felt very confident under his care. His strong academic background from top universities gave me comfort in his technical knowledge base. If someone is "opening you up" you need the best. Very intelligent. He was very honest and gave us few detailed options. He uses the latest technology (Oxinium) in replacement joints that many dr's do not (other dr's use the traditional titanium material) as it requires special training. He gave us a video to watch explaining this technology and answered our questions. My own mom had a total knee done in 2014 and I was so happy with his work. I recently had my mother in law have 2 of her knees done on 2 separate occasions. He reached out to us at home 24 hours after her discharge to our home to make sure mom was doing ok. Anytime I needed to call the Dr office, he personally would call me back even after hours from home. A few weeks later we noticed due to a pre-existing condition she had developed tough scar tissue so he recommended an outpatient "Manipulation" procedure to break it all up. He assured us that will give us more mobility and less pain with continued PT. He was correct. Mom is feeling more flexibility and range of motion and pain is minimzed. What I like about Dr Biviji is he really cares and he senses if a patient feels uneasy so he will want to make sure they are comfortable and encourages asking many questions to ease the comfort of any procedure. He makes recommendations as if it was for his own mom. I strongly recommend Dr Biviji and his assistant for any orthepedic surgery. He is very easy going, mild natured, yet very thorough. Most important smart and great bed side manners for a physician. read more

Dr. Biviji did my right Total Knee Replacement and the experience has been nothing more than wonderful. When your physical therapist (who never worked with a patient of his) tells you that you are doing this great because of the surgeon - you then know he is the best. The front office personnel answer all the phones there is no pushing buttons till you get the right department. And, they always address the problems on the phone immediately. Love this front office. lf I need another TKR I will not hesitate for a second that is how much confidence I have in Dr Biviji. read more

I rarely provide Yelp reviews, good or bad, but am making an exception this time. I strongly believe Dr. Biviji and his staff should be commended. In 2016 I had a total knee replacement preformed by another OC surgeon. I had several complications and after 1 1/2 years sought a second opinion. Dr. Biviji was amazing! After his exam he concluded a heavy layer of scar tissue had formed around the prosthetic. Dr. Biviji recommended an outpatient procedure he felt confident would give me 20 degrees greater range of motion, which it did! I feel like a new person now. I am able to hike, cycle, return to the gym and an active life style without knee discomfort. Dr. Biviji is a skilled surgeon who is personable and willing to spend the extra time with his patients. His office staff is friendly and exceptionally easy to work with. Thank you Dr. Biviji. read more

I have had an excellent experience with Dr. Biviji. He determined and explained to me how the damaged plate on my clavicle was causing me discomfort. Orthopedic Surgeons I visited in the past did not acknowledge the level of discomfort I was in. Dr. Biviji explained the surgical option and answered all of my questions patiently. Within a few weeks of the initial consultation a surgery to remove the plate and six screws was complete. It was a very comfortable process. He and his staff always gave me the time of day when I had questions or concerns. And now, a couple of weeks after my surgery I am healing well and have regained pain free mobility that I never expected to have again. I feel very lucky to have had Dr. Biviji as my Orthopedic Surgeon. read more

Dr Biviji preformed bilateral knee surgery on me March 5th, and I have to say that if you're in need of replacement surgery he's the best! I went to several surgeons and he was the most caring and sensitive one that I interviewed. He didn't rush me his bedside manner in my opinion was impeccable. My very first impression was OK, totally impressed. After reviewing my X-rays he said both are bad and we can do both. I was like NO way! He didn't insist or pressure me he just said okay we can do one at a time, and I said I would decide when I wanted to do the surgery and he was ok with that. So during the holidays I called to see about scheduling surgery ASAP and the staff was limited and I received a call from Dr Biviji personally to let me know when the scheduler comes back after the holidays they would schedule me for the surgery and they did. On surgery day he came in and was very comforting for me and it was a very good experience (if there be such a thing) and I did not regret my decision to have both done at the same time. read more

Although the wait is usually about 30 min before I am seen, Dr. Biviji is excellent. He is very thorough in explaining my injury and what my options are for treatment. I am now 3 months out from a patellar tendon ACL reconstruct surgery. The surgery went great and I'm coming along really well w/ my recovery. I would highly recommend Dr. Biviji if you need a great Ortho. surgeon. read more

I've had two shoulder surgeries with Dr. Biviji. He is an excellent surgeon. I have seen him many times over the last 5 years or so. He does a great job injecting my shoulder when I need it. His medical assistant, Andrea, is great as well. The wait can be long so I make my appointments first thing in the morning. I work for a local GP and refer all our patients to him and have never had a complaint, only positive reviews! read more
