Tendoperiostitis in the lateral femoral condyle in long-distance runners.

In the thigh, muscle tears are uncommon amongst joggers, but muscle sheath tears with herniation are frequent, but insignificant. In the hip, trochanteric bursitis is very common. Avulsion fractures of the hamstring origin have been seen in young runners, as have avulsions of the sartorius origin. Osteoarthrosis of the hip joint is not infrequent among older joggers. Even after hip replacement, jogging may be resumed.
