Although I treat a fair amount of Hamstring Tendinosis in my clinic, I just as frequently treat “pulled” or torn hamstrings. One of the unique characteristics of Hamstring Tendinosis is that it can effect either or both ends of the muscle.
Sometimes I see Hamstring Tendinosis at the upper attachment point of the hamstring muscles (the Ischial Tuberosity — often referred to as the “sits” bone), and sometimes I see it near the back of the knee. It can occur either place, but is probably a bit more common behind the knee.
