I have no remaining meniscus and as a result have severe osteoarthritis in both knees. I was scheduled for double knee replacement surgery in the Bay Area 18 months ago; however, about three weeks before my scheduled surgery I had a consultation with Dr. Jeff. He suggested an alternative treatment of Prolozone injections. I began treatment with Dr. Jeff that day and felt such immediate improvement in reduction of knee pain and increased mobility that I cancelled the knee surgery. Routinely since then, about every six months I receive prolozone injections from Dr. Jeff in both knees. I have experienced similar positive results after each treatment. I have recommended others with joint problems to Dr. Jeff and they have also experienced similar results. Thanks, Dr. Jeff!!
