This study aimed to compare muscle strength, functional fitness, and proprioceptive sensibility in anterior cruciate ligament (ACL) reconstruction with or without preserving remnant tissue.
Forty patients who underwent ACL reconstruction between September 2007 and December 2009, twenty each with and without preserved remnant tissue, were evaluated at the 6-month post-operation follow-up. The Lysholm knee score, IKDC subjective score, Tegner activity score, knee joint laxity with KT-2000, isokinetic strength test, and balance test using the Biodex system III were evaluated. For functional performance testing, co-contraction, shuttle run, carioca, one leg hop, and balance tests were performed. The active and passive joint position senses were assessed to evaluate proprioceptive function.
In the results of clinical outcomes, namely the AP stability test, isokinetic strength test, and functional performance test, both groups showed no statistically significant difference. The results of active JPS showed significant difference between groups, however, there was no statistically significant difference in the results of passive JPS.
We concluded that there was no significant difference in clinical evaluation, isokinetic strength test, and functional performance test in ACL reconstruction with or without preserving remnant tissue, except for in the proprioceptive function test. Therefore, we suggested that patients’ participation in appropriate rehabilitation program can help improve muscle strength and functional performance. However, only the change of joint position sense test was revealed a statistically significant difference in the results between groups. According to the results, the method of ACL reconstruction that preserves remnant tissue may have a positive effect on recovery of proprioceptive function in the knee joint.
