Context:

Anterior cruciate ligament (ACL) reconstruction with doubled hamstring autograft might not sufficiently improve fundamental sports abilities of patients with ACL-deficient knees.

Objective:

To clarify whether ACL reconstruction using the hamstring graft can improve fundamental sports abilities.

Design:

Patients were examined twice, preoperatively and 2 years postoperatively, using the conventional evaluation scales and performance tests.

Participants:

15 athletic patients with ACL reconstruction using hamstring autograft.

Measurements:

A stairs-run test and figure-8 one-leg hop test. Muscle strength and knee stability were measured with Cybex® II and KT-2000® arthrometers, respectively.

Results:

There were no significant differences between the preoperative and postoperative results in the performance tests. The degree of postoperative recovery in the subjective score, the anterior translation of the tibia, and the isokinetic muscle strength was not significantly correlated with the degree of restoration in each performance test.

Conclusions:

Postoperative restoration as measured by conventional evaluation scales is not correlated with restoration of sports abilities in patients with ACL insufficiency.
