Dr. Dubroff treated my knee pain that I have been dealing with for years. I grew up playing soccer up to the college level. Now I play as a hobby the last few years. A few years back I was injured and raptured my patella ligament. It required surgery and physically therapy. Years later I have bad Crepitus (grating, crackling or popping sounds and sensations experienced under the knee cap)… It is painful to do full squats for example, and even begins to be painful when just sitting too long in one position (i.e. airplane, car etc). I saw Dr. Dubroff for Prolo Therapy to help relieve the pain and give to provide some natural healing for the inflammation. I get great results from the Prolo, and highly recommend it, especially for active people
