Abstract

BackgroundDisruption of the anterior cruciate ligament ACL is one of the most frequent musculoskeletal injuries affecting physically active men and women. In the United States, an estimated 200,000 ACL reconstructions are performed annually. One of the most common complications of ACL reconstruction is loss of extension. The purpose of this study was to assess the effects of the hyperextension maneuver on preventing knee extension loss after arthroscopic ACL reconstruction.

Materials and methodsIn this prospective randomized clinical trial study, 100 adult patients with a documented complete ACL tear were randomized to two groups. All patients underwent arthroscopic ACL reconstruction with quadrupled semitendinosus and gracilis autograft by the senior author based on the same technique and instruments. However, the hyperextension maneuver was only performed in 50 patients during autograft fixation on the tibial side case group. The postoperative rehabilitation protocol was similar for both groups. The knee range of motion and extension limit was evaluated at 2, 6, 12, and 24 weeks and at 1 year postoperatively.

ResultsOne hundred patients 88 male and 12 female aged from 17−36 years average 26.9 years were included in our study. The two groups were similar regarding age, sex, and dominant side involvement P >0.4.The difference between the two groups was significant only at 2 weeks P <0.02. After 2 weeks, although the rate of limited extension was higher in the control group, no significant difference was seen between the groups.

ConclusionAlthough the hyperextension technique during graft fixation on the tibial side may induce better range of motion in the first 2 weeks after ACL reconstruction surgery, this effect is not significant after 2 weeks.

Level of evidenceTherapeutic level II.
