- Abstract
Introduction: After anterior cruciate ligament reconstruction (ACLR), studies have demonstrated early use of OKC did not seem to affect the graft healing process and laxity. Objective: The main objective was to determine whether quadriceps and hamstring strengthening in a rehabilita- tion program involving early open kinetic chain (OKC) and/or closed kinetic chain (CKC) knee joint exercises had an influence on graft laxity at 1, 3 and 6 after ACLR. The secondary objective was to assess whether the early use of OKC exercise affects intrinsic graft laxity between 1 and 6 months postoperatively. Design: Non randomized, single blinded, prospective case control study Methods: This study included 53 patients following a ACLR with hamstring graft. Participants were retrieved from 2 rehabilitation centers that followed different ACLR rehabilitation programs with regards the use of OKC exercises; the intervention group (n= 25) that performed OKC and CKC exercises in combination and the control group (n=28) that performed only CKC exercises. (1;2) Anterior knee laxity was measured using the GNRB device on the operated limb, and compared to the contralateral control limb. Three evaluations were performed at 1, 3 and 6 months after the ACLR. The difference between both limbs was calculated and used to determine the variation in anterior laxity throughout the first 6 months after surgery. (1;3) Results: No differences were observed in knee laxity at 1 (p = 0.263), 3 (p = 0.263) and 6 months (p = 0.256) follow up between intervention group and control group. No differences were observed in within-group graft laxity between 1 and 6 months after ACLR in intervention group (p = 0.155) and control group (p = 0.690). Conclusion: The initiation of OKC exercises doesn't seem to increase the ACLR graft laxity as compared to the rehabilitation program with only CKC exercises.
