Dr. Kronick is Board Certified in Orthopaedic Surgery and has 17-plus years of experience in treating patients. He began practicing orthopedic surgery in 1995 after completing his medical training at the Chicago Medical School and his residency at Wayne State University in Detroit.

Following residency, he completed an Adult Reconstruction Fellowship at the Rush Orthopaedic Institute under the direction of Wayne G. Paprosky, M.D., where he advanced his skills in hip and knee replacement, revision hip and knee surgery, and the management of bone loss. He then performed a Biologic Hip Reconstruction Fellowship at Wayne State University under the tutelage of Jeffrey Mast, M.D. and Keith Mayo, M.D. where he refined his skills in the art of osteotomy and internal fixation.

Following his education, he joined the faculty at Wayne State University as an Assistant Professor and was named Teacher of the Year in 2000. Dr. Kronick’s special training and experience make him one of the best joint replacement surgeons in California. He is one of the few surgeons skilled in the reconstruction of failed hip and knee replacements with major bone loss. He manages the more difficult reconstructive problems in the area. He is willing and able to take care of difficult hip and knee reconstructive problems that other surgeons won’t tackle.

Dr. Kronick has been published in peer-reviewed journals and has been asked to present his published work at many nationally referred conferences.

Dr Kronick is an amazing and kind surgeon. He explained the process and helped set expectations. I never second guessed my decision and he delivered as promised. He corrected my leg length discrepancy made a beautiful 10” incision, even better carried the line from my previous surgery and I’m healing nicely. I would definitely recommend Dr Kronick to anyone he is the absolute BEST! Thank you!!! :)))

Just wanted to give a shout out to Dr. Kronick and his staff. Im 4 weeks out of surgery for TKR. What a great job he did for me. He really made me feel very comfortable with the procedure and confident in him prior to my surgery. I would add that, I couldn't have been more nervous prior to meeting him. If your going down this path, do your homework. I believe I couldn't have done better. Thanks again to Dr. Kronick and his staff.

Dr Kronick was prompt in seeing me though I was a new patient, and very quick to give meaningful help to a very painful leg issue. The office followed up quickly with a further appointment to address findings on xray. Staff was gracious and helpful. This is a well managed and experienced office that provides expeditious care and follow through.
