Follow-up

Return to Play

A common threshold for return to play is when the strength of the injured hamstring has at least 90% of the strength of the unaffected hamstring and when the patient has full ROM. At least a 50-60% hamstring-to-quadriceps ratio is desired before allowing the athlete to return to play.

Strength testing is performed using isokinetic exercise equipment. In addition, it is also important to ensure the return of normal flexibility and endurance before the patient returns to play; reinjury is most often due to lack of both.

Therapy that incorporates sports-specific activities can help minimize the risk of reinjury.

Complications

Returning to play too early is a common factor leading to chronic hamstring pain and injury. Reinjury rates as high as 77% may be related to areas of calcification and inflammation in the hamstring after injury. Scar formation may impinge the sciatic nerve, resulting in hamstring syndrome. Surgery has rarely been used to break up painful scar tissue.

Prevention

The implementation of proper warm-up and maintenance of flexibility and adequate strength are needed to prevent future injuries. The patient should be aware that as fatigue sets in, the risk of injury increases. With improved form and by emphasizing knee flexion during activities, the risk of further injuries is minimized.2,7,8,11,12,13

Prognosis

With minor activity limitations and proper rehabilitation, the prognosis is good for hamstring strains and even partial tears. Complete tears also heal but require a significantly longer and more intensive rehabilitation program.

Miscellaneous

Medicolegal Pitfalls

  • An individual's premature return to play may result in recurrent injuries and chronic debilitating hamstring pain. Monitor individuals for increasing pain, which may indicate an expanding hematoma, potential compartment syndrome, and a need for further workup.
