He has a particular interest in the treatment of rotator cuff and dislocation injuries in the shoulder and has helped pioneer several new techniques for the treatment of these problems. One of his inventions, the transporter device, is used to perform procedures that previously required open repairs. He has published numerous scientific journal articles and textbook chapters on subjects like knee ligament reconstruction techniques and arthroscopic shoulder surgery. Dr Karzel has also presented many scientific papers and is frequently invited to give instructional course lectures at national and international orthopedic meetings. He remains actively involved in several research projects concerning knee and shoulder injuries.

"So I am a cement/concrete finisher and use my hands, arms, and knees on a daily basis. I have been suffering from shoulder pain for months. I have trouble doing my job and living a normal life pain free. So I was referred to SCOI and ended up choosing Dr. Karzel and my experience from day one with him and SCOI's staff have been excellent. I just had my surgery 3 days ago and even though I'm in pain recovering as I type this message, it is well worth it to me. I strongly recommend him and everyone I have came across through physical therapy to Dr. Appt's have spoken highly of him. I know and am sure I will recover and be back to normal soon. Staff in the Van Nuys office were outstanding, from the anesthesiologist to the Dr. doing the nerve block procedure made me feel really comfortable and not worried at all. The nurse Jennifer H. and OR nurse Kindra were really nice and professional. Thank you all." - Jimmy M.
"I can't tell you enough how wonderful everyone is. I was treated kindly and carefully. Because my husband and I had boys that played football in the Santa Clarita Valley, Dr. Karzel was the go to ortho guy. We have known him for years. He did shoulder surgery on my husband in 1993. It was very hard for him because he got full surgery. I just had the orthoscopic surgery. My husband is very jealous because after 3 weeks, I can pull up my pants on my own (anyone who has had this surgery knows what an accomplishment that is). I absolutely love Healthloop. I hope the person that did that program gets lots and lots of money. It's really nice to get answers to questions almost immediately. I don't think, given the choice, that I would go to any other ortho place. I am constantly telling people to go to SCOI." Carolyn L.
"Fortunately or unfortunately, my family (mainly my kids) have been going to SCOI for over 11 years. Both of my kids (now 21 and 19 and playing sports in college) have played sports since they were 5 years old. Majority of the doctors that we have seen at SCOI have been outstanding. Dr. Blecher treated my son for a concussion he received from football and he and Dr. Barcohana treated him for a back injury and Dr. Jaivin for a foot injury. Dr. Karzel treated and performed meniscus surgery on both of my daughters knees and Dr. Burns treated her for a broken leg. Dr. Karzel also treated me for frozen shoulder. The treatments and surgical procedures that were performed were exceptional. We are truly blessed that our medical coverage includes SCOI because I would not want to go anywhere else for treatments for our family. These doctors were knowledgeable, up to date on latest technology and their assistants were always courteous and available, especially Carol Schmittker and Mickie Wolfe and I cannot forget Kathy Hughes. I'd also like to say Dulce Cabrera has always been extremely helpful over the years. Because of these doctors, my son wants to be a Physical Assistant within the Sports Medicine field." - Dionne W.
"On Thanksgiving break of 2012, Dr. Karzel performed ACL replacement surgery on my then 15 year old son as a result of a football injury.
In February of 2013, just three months after surgery, Roger's physical therapist said there was nothing more he could do for him. Under the physical therapist's supoervision, Roger was doing everything on his knee with no ill effects from the injury or the surgery. When I asked the physical therapist why he was doing so well after such a catastrophic injury in such a short time, he said Roger was 15 years old and had a good surgeon.
In May of 2013, Dr. Karzel cleared Roger to play his first love, lacrosse, again. In the summer and fall of 2013, Roger competed in many lacrosse tournaments and caught the eye of many a collegiate coach that are looking at Roger for collegiate level lacrosse. I would like to thank Dr. Karzel and all the folks at SCOI for such a wonderful outcome to a catastrophic injury." -- Robert W.
"This is our third experience with SCOI. Dr. Karzel operated on my son twice, and me once. All have been very good experiences. We have recovered and are doing well. Dr. Karzel explained everything well to us, and the follow-up went well too. I appreciated the care I received and the success of the surgery." -- Dale S.
"I never thought I would have to have shoulder surgery, but I did. Then, I thought it would take a long time recovering after surgery. It didn't. I was amazed how well I felt after two weeks, and I was able to return to work. It has been seven-and-a-half months since I had surgery, and I am doing workouts with weights and bands to strengthen my muscles along with other cardio workouts. I am forever grateful for the expertise and caring practices of Dr. Karzel for fixing not only my shoulder but also my frayed biceps. My son also had knee surgery performed by Dr. Karzel, and we were both impressed by how well he took the time to explain exactly what happened and how he was going to fix the problem. Surgery is not so scary after all." -- Marie W.
"Both of my daughters have been treated by SCOI, and their experiences from diagnosis to surgery and then rehabilitation have been excellent; so when I started to play tennis regularly and a knee "situation" came up, of course my first thought was to come and see Dr. Karzel and his staff at SCOI. Their experience, knowledge, and welcoming attitude is the best. I recommend SCOI to anyone who asks about a reference to an orthopedist!" -- Lina G.
"Dr. Karzel is the best! After a year and a half since my shoulder surgery, I do not even remember having it unless someone asks about it. The scars are almost invisible and I am able to work out and enjoy any activity. It’s with my deepest gratitude to Dr. Karzel for my strength and well-being. His staff is also wonderful and caring. SCOI is the only place I recommend to anyone." -- Marie W.
"Dr. Karzel and his assisting physician did extensive reconstruction of my right shoulder rotator cuff. My recovery, elimination of discomfort, and returned mobility has been outstanding. My heart felt thank yous to Dr. Karzel and all of his staff." -- Mickey B.
"I came to Southern California Orthopedic Institute for knee surgery, a torn meniscus and arthritis. I was given kind and thoughtful care for my surgery. The procedures were explained to me in detail including risk and expected benefits from the surgery. The surgery went well and the follow-up care has been fabulous. I would recommend the doctors, PAs, and friendly staff to anyone seeking orthopedic treatment. Honestly I felt like I was treated like family." -- Janet M.
