I suffered from severely painful patellar tendinitis for 5 years. Now I can complete 100-mile bike rides pain-free. I credit my success to "eccentric exercise." Through trial and error, after reviewing the medical literature, I found a regimen that helped me eliminate knee pain. Do not do these exercises if you have inflammation and until you consult with medical professionals to determine whether these exercises are appropriate for you.
