Knee function after anterior cruciate ligament ruptures treated conservatively.

Author information

  • 1Department of Orthopaedic Surgery, Huddinge University Hospital, Sweden.


Thirty-nine patients with ruptures of the anterior cruciate ligament (ACL) were treated conservatively and were subsequently examined at an average of 5.7 years after injury, the uninjured leg acting as a control. The Tegner activity score was significantly lower than the desired activity level. No patients were free of symptoms and only two could take part in sport which involved pivoting. The isokinetic knee extensor and flexor torques, as well as the one-leg-hop and instrumented knee joint laxity tests, were significantly impaired at follow-up. Functional impairment was not related to tests of knee joint laxity. Few patients were pleased with their subjective knee function after an ACL rupture despite thorough initial rehabilitation.
