Abstract: OBJECTIVE: Compare muscle strength and hop performance trajectories between patients with and without generalized joint hypermobility (GJH) during the first two years after anterior cruciate ligament (ACL) reconstruction. DESIGN: Retrospective study using prospective registry data. SETTING: Rehabilitation-specific registry. PARTICIPANTS: 1223 patients (23.8 % GJH; mean age 22.5 ± 5.2 years; 52 % female) underwent hamstring tendon (HT) or bone-patellar tendon-bone (BPTB) autograft ACL reconstruction. MAIN OUTCOME MEASURES: Quadriceps and hamstring strength limb symmetry index (LSI) and body weight-normalized strength, and vertical-, distance-, and 30-s side hop LSI at 10 weeks, 4, 8, 12, 18 months, and 2 years were analyzed. Linear mixed-effects models, adjusted for age and sex, compared trajectories stratified by autograft. RESULTS: No differences in strength or hop performance trajectories were observed between groups. At 2 years, quadriceps and hamstrings LSIs were comparable (HT: quadriceps 99-100 %, hamstrings 99 %; BPTB: quadriceps 94-99 %, hamstrings 103-104 %). CONCLUSION: There was no difference in muscle strength recovery trajectories, evaluated as LSI and body weight-normalized strength for the quadriceps and hamstrings muscles, or in the vertical hop, hop for distance, and 30-s side hop test LSIs between patients with and without GJH during the first two years after ACL reconstruction, regardless of whether HT or BPTB was used.
