No results posted yet for this study

Summary

This prospective observational study will compare recovery after anterior cruciate ligament reconstruction using quadriceps tendon autograft or hamstring tendon autograft. The main goal is to examine differences in knee muscle strength recovery during the early and mid-term postoperative period. Participants aged 13 to 45 years who undergo unilateral ACL reconstruction and meet the eligibility criteria will be followed at Hacettepe University. Knee extensor and flexor strength will be assessed using isometric testing at postoperative weeks 4, 8, and 12 and month 6, and with isokinetic concentric testing at months 3 and 6. Functional outcomes and kinesiophobia will also be evaluated at month 6 using IKDC, KOOS, and the Tampa Scale for Kinesiophobia. All participants will receive the same standard postoperative rehabilitation program under physiotherapist supervision. The study aims to clarify whether graft type is associated with different patterns of muscle strength recovery and functional improvement after ACL reconstruction
