Does Gracilis Preservation Matter in Anterior Cruciate Ligament Reconstruction? A Systematic Review

摘要: Purpose To analyze the effect of gracilis harvest on hamstring strength, patient-reported outcomes, and anterior knee laxity after cruciate ligament (ACL) reconstruction. Methods A systematic review literature was performed to identify studies comparing results semitendinosus (ST) versus semitendinosus-gracilis (ST-G) for ACL meta-analysis using a random effects model determine overall pooled estimates influence additional Results Twelve were identified included in review. ST-G noted decrease isokinetic strength at 60° per second by 3.85% relative isolated ST ( P  = .01). Decreased isometric also group both 90° flexion (mean difference: 5.55%; .03) 105° 110° 13.68%; .003). Active angle loss be greater 3.91°; .006). No differences found 180° 240° 3.20%; .08), outcome scores 1.87 points; .06), or 0.03 mm; .78) based harvest. Conclusions The addition an reconstruction statistically significant, but likely not clinically relevant as well outcomes. Hamstring deficits may larger higher angles. Level Evidence III, level I-III studies.
