"Outstanding experience, Dr. Friedman has thoroughly updated me with all information, Vanessa has been very professional, she has been a great help in guiding me on what to do, overall experience has been very gratifying." – Michael P. 

"I don't even know where to begin, but I just want to say that Dr. Marc Friedman was wonderful and I would recommend him to ANYONE who needed an orthopedic surgeon with his specialty. I had taken a bad fall off a mountain bike and first saw an ER doctor in Park City, then I rushed home to L.A. to see my primary doctor at Motion Picture (now UCLA) Health Center, both of whom thought that I may have ruptured the right quadricep tendon, as I could not life my right leg at all. Then I saw the orthopedic surgeon that my primary doctor gave me a referral for, who was horrible. This surgeon also thought that the tendon was ruptured and had me schedule a surgery, but instead of scheduling it at a Motion Picture Facility (which would have been covered by my insurance, since he was contracted with them to get the referral), his assistant gave some story about no Motion Picture facilites being available and that I would have to have it done at his surgical center in Santa Monica (where I would be out of pocket since it was out of network!). I then had an MRI that evening and when the preliminary results came back the next morning, the radiologist indicated that there was NO RUPTURE, just a lot of tissue damage all throughout my quad muscles, in addition to a hematoma. But that unscrupulous surgeon called me upon receiving the radiologist's report to tell me "not be confused about the results" and that I would still need the surgery for "everything to heal properly".  THAT is when I decided to get a second opinion and asked Dr. Simic (who I had used for a hand surgery a few years earlier) for a recommendation. I then got the referral for Dr. Friedman and he was nothing short of terrific. I cancelled the other surgery and scheduled one with Dr. Friedman, but as he studied the MRI, he showed my daughter and me that the tendon was indeed intact, and explained the other parts of what he was seeing on the MRI. He said he wasn't sure that I needed the surgery and it could perhaps end up being exploratory. Then he went over the MRI with his SCOI radiologist and called me the next day to CANCEL my surgery. He said that it looked like the tissue damage would heal in time, and that is in fact what happened. Within three months I was running, roller-blading, and playing softball again. Thank goodness for Dr. Friedman and his very ethical approach to his practice. The other surgeon would have gone ahead with a surgery that I ended up not needing. I reported him to my Motion Picture insurance plan - and hopefully they will never refer him again. In the meantime, I can't say enough great things about Dr. Friedman!" - Laura G.

"I developed patella baja after a patellar fracture, and travelled from Iowa to see Dr. Friedman, as I could not find a surgeon in my state with experience in treating this condition. Dr. Friedman has been superlative in every way and I am hopeful that I will be able to return to some of my athletic activities, in addition to walking and taking stairs with less difficulty. I am only three weeks post op at this time, but I can tell that the tightness in my knee is gone. My experience with regard to anesthesia and medical management of pain, GI complications of pain medications, etc. has been excellent. The nerve blocks performed by Dr. Bowles lasted about thirty hours, making my immediate post op experience very comfortable. Also, the meticulous attention to rehab with the CPM machine, cooling machine, and muscle stim device has been appreciated greatly. I would highly recommend SCOI to others, and Dr. Friedman specifically excels in every way. Thank you." - Nancy S.

"I saw Dr. Getelman before I elected to have my knee surgery. His services were great at the time, so I elected to have my knee replaced by Dr. Friedman. He did a fantastic job. I am walking with no pain. This is thanks to Dr. Friedman and my physical therapy group. I am so glad I had this done. I feel like I have my quality of life back. I recommend these doctors and the SCOI group highly." -- Carole P.

"I have a bum right knee. Both doctors did a great job and I'm know going for physical therapy at SCOI with Brian the therapist. He's really good. Keep up the good work!!!" -- Victor R.

"I had knee replacement surgery on my left knee April 3. Three weeks later I feel great I want to thank Dr. Friedman and Vanessa for everything. My experience with Southern California Orthopedic Institute has been excellent. Thanks again for everything." -- Louie M.

"I had a knee injury that Dr. Bloze looked into by doing X-Rays and a MRI. Once she determined the injury she quickly referred me to Dr. Friedman. SCOI is clearly a one stop medical facility. I love that the doctors can easily communicate and share information via the computer medical records route. This makes it so very easy in getting quick and complete treatment with several doctors sharing their opinions. It is very comforting." -- Vivian T.

"I had a wonderful doctor. Dr. Friedman replaced my left knee in June of 2011 and I had a wonderful experience with that knee. I told him he spoiled me. I had my right knee replaced January 30 of this year and some trouble and slower recovery, but still recovering wonderfully. He is thoughtful, kind, caring, and I am coming along with the healing beautifully." -- Angelina T.

"I had two knee replacements in 2013, both done by Dr. Friedman. I feel fantastic with my new knees! Dr. Friedman, Vanessa, and everyone involved at SCOI, went above and beyond the call of duty to make this huge experience in my life as comfortable as possible. Thank you!" -- Louie M.

"I started with SCOI in the early 1980's with Dr. Del Pizo, who is recently retired, for what was called impingement syndrome in my right shoulder. I have since had knee surgery from Dr. Friedman, back surgery from Dr. Grossman, and six rounds of painless injections into both knees by Dr. Burns. The surgeries were completely successful, and the knees are still surviving all my sports activities. I have sent so many guys to Dr. Burns, that if he were a network marketing business, I'd have a great down line!!" -- Rick L.
