    The effect of open versus closed kinetic chain exercises on anterior tibial laxity, strength and function following anterior cruciate ligament reconstruction: a systematic review and meta-analysis

    J Orthop Sports Phys Ther 2018; 48(7): 552–66

    ACL injuries are common in sporting populations. Ultimately, an ACL injury will mean long periods of time away from training and competition. Postoperative rehabilitation is a mainstay for improving function and reducing the risk of reinjury. Debate exists on the best method to strengthen the quadriceps, in particular the use of open kinetic chain (OKC) compared with closed kinetic chain (CKC) exercises. One of the proposed side effects of early use of OKC exercise has been graft laxity. What do we know when it comes to our exercise selection after ACL repair?

    This review aimed to determine if the use of OKC quadriceps exercises resulted in differences in graft laxity, strength and function when compared with CKC exercises. Low to moderate-quality evidence found no difference in laxity, strength and function (patient or physical) with the early or late introduction of OKC after ACL repair, when compared with CKC exercises. However, readers should tread cautiously when interpreting these findings given the limited to moderate level of evidence assigned to these findings.

    Take home message: Before we adopt OKC as a mainstay of ACL rehabilitation we require a greater body of high-level evidence to determine the short and long effects.
