PURPOSE: To compare postural stability in patients with isolated anterior cruciate ligament (ACL) tears and ACL tears with associated meniscal tears.

METHODS: Quadriceps and hamstring muscle strength and their ratio, as well as the relationships of these parameters with postural stability, were compared in 23 patients with isolated ACL tears and 27 with combined ACL and medial meniscus tears. Postural stability was determined from the anterior-posterior, medial-lateral, and overall stability indices using the Biodex Stability System.

RESULTS: On both the involved and uninvolved sides, there were no differences in mean stability indices, including anterior-posterior, medial-lateral, and overall stability indices, in patients with isolated and combined ACL tears. In patients with isolated ACL tears, both overall (2.3 ± 1.2 vs. 1.8 ± 1.4, p = 0.033) and medial-lateral (1.2 ± 0.6 vs. 1.0 ± 0.5, p = 0.031) stability indices were significantly higher on the involved compared to the uninvolved side. These differences, however, were not observed in the combined ACL tear group.

CONCLUSION: No significant differences in postural instability on the affected and unaffected sides were observed in patients with isolated ACL tears and those with combined ACL and medial meniscus tears. These findings indicate that there is no need to reduce the goal of restoring proprioception in patients with combined compared with isolated ACL tears.III.
