The effect of meniscal pathology and management with ACL reconstruction on patient-reported outcomes, strength, and jump performance ten months post-surgery

The purpose of this study was to examine the differences in patient-reported outcome measures, isokinetic strength, plyometric ability and ability to meet return to play criteria ten months after anterior cruciate ligament (ACL) reconstruction surgery between those who underwent meniscectomy, those who underwent meniscal repair and those with no meniscal intervention alongside ACL reconstruction surgery. Three hundred and thirteen athletes with clinically and radiologically confirmed ACL ruptures were included in this study. Participants were grouped according to their intra-operative procedures (isolated ACL reconstruction surgery n = 155, ACL reconstruction surgery with meniscectomy n = 128, ACL reconstruction surgery with meniscal repair n = 30). Participants completed patient-reported outcome measures questionnaires (Marx Activity Rating Scale, the ACL Return to Sport after Injury and the International Knee Documentation Committee Score) and completed a battery of objective functional testing including isokinetic dynamometry and jump performance testing (countermovement jump and drop jump) between 9 and 11 months after surgery. No significant between-group differences were identified in any metric relating to patient-reported outcome measures (p = .611), strength and jump measures (p = .411) or the ability to achieve symmetry-based return to play criteria (p = .575). Clinically, these results suggest that concomitant meniscal surgery has no significant effects on patient-reported outcome measures, strength and jump metrics at the return to play stage post-operatively and can inform the pre-operative counselling of those awaiting ACL reconstruction surgery with likely meniscal intervention.
