Strength, Functional Outcome, and Postural Stability After Anterior Cruciate Ligament Reconstruction.

摘要: OBJECTIVE: To compare postural stability, single-leg hop, and isokinetic strength measurements in subjects after anterior cruciate ligament (ACL) reconstruction with an age- activity-matched control group. DESIGN AND SETTING: Subjects reported to a sports medicine/athletic training research laboratory for testing. one testing session total test time of 1 hour. SUBJECTS: Twenty ACL reconstructions (ACLRs) 20 controls were selected participate this study. An arthroscopically assisted central one-third bone-patellar tendon procedure was used repair the ACLs. MEASUREMENTS: We measured concentric eccentric peak torque (Nm) knee extensors flexors at 120 degrees 240 /second on dynamometer. Unilateral bilateral dynamic stability as index anterior-posterior medial-lateral planes Biodex Stability System. tested hop distance measure objective function. RESULTS: found no significant difference between ACLR or knee-flexion scores. On distance, hopped significantly shorter distances involved limb than uninvolved limb. Furthermore, subjects' less when compared control-group matched limb, performed better The produced greater leg leg. In addition, group CONCLUSIONS: After (mean = 18 +/- 10 months), hop-for-distance scores quadriceps not within normal limits contralateral Our results suggest that single-limb different average follow-up months surgery.
