The hamstring muscles are located at the back of the thigh and are important for hip extension and knee flexion. A partial or complete tear of a tendon can result from forceful movement or a sudden change in acceleration.

Hamstring injuries are most common in athletes who participate in activities that involve running, such as track, soccer and basketball, and in sports like water skiing. Individuals who have suffered a previous hamstring injury are at greater risk of hamstring tendon tears.

The symptoms of a hamstring tendon tear include:

• Immediate sharp pain
• A “popping” sound or sensation at time of injury
• A sensation of the leg giving way
• Bruising or swelling along the back of the thigh or knee
• A gap where the tendon has ruptured
• Pain and discomfort while sitting
• Difficulty putting weight on the leg
• Difficulty bending or straightening the knee

Early diagnosis and treatment by a knee specialist at Lancaster Orthopedic Group is the key to a successful outcome for a hamstring tendon tear. Delay may result in the formation of scar tissue and retraction of the tendons.

In cases of partial tendon tears, conservative treatments include rest, ice, anti-inflammatory medications, immobilization of the knee for several weeks, and physical therapy. If the hamstring muscle or tendon is completely torn or frayed, your physician may recommend surgical repair.
