The hamstring tendon attaches the hamstring muscle to an area just below the knee joint known as the tibia. It assists with hamstring muscle and aids in bending the knee. The hamstring muscle is located at the back of the thigh and stretches from the pelvis to the knee joint.
Hamstring tendonitis is a condition that occurs when the hamstring area is stressed from injury. This can occur during a physical activity or sport that involves a sudden change in direction and stopping. Hamstring tendonitis involves pain in the area due to the small tears that occur where it is attached to the bone.
