Context: Joint loading following anterior cruciate ligament reconstruction (ACL-R) is thought to influence long-term outcomes. However, our understanding of the role of meniscus repair at the time of ACL-R on early joint loading is limited. Objective: To assess if differences in total energy absorption and energy absorption contribution of the hip, knee, and ankle exist in the early stages of rehabilitation between patients who received an isolated ACL-R and those with concomitant meniscal repairs. Design: Cross-sectional. Setting: Clinical laboratory. Patients: Fifty-nine human subjects, including 27 who underwent ACL-R and 32 who underwent ACL-R with concomitant meniscal repairs. Main Outcome Measure: The total energy absorption and the energy absorption contribution of each joint of both the involved and uninvolved limbs during a double-limb squat task. Results: There were significant differences in energy absorption contribution between groups at the knee joint (P = .01) and the hip joint (P = .04), but not at the ankle joint (P = .48) of the involved limb. Post hoc analysis indicates that preoperative hip and knee loading differences exist and when you control for preoperative loading (analysis of covariance), the postsurgery difference was not significant. Conclusions: The results of the study suggest that the additional surgical procedure of MR may not have had negative effects on joint loading during squatting at 12 weeks.
