Anterior Cruciate Ligament (ACL) Reconstruction Surgery

The primary goal of this RCT is to evaluate the effects of isokinetic training compared to plyometric training after 4weeks of intervention in patients aged 18-40 years who have undergone ACLR surgery. The primary question to answer is which of the two interventions (isokinetic or plyometrics) has superior effect in the improvement of muscular strength, functional performance and patient-reported outcomes in ACLR patients. Participants will be divided into two groups. both groups received standard rehabilitation for 4 weeks, followed by adding: Group 1: receives isokinetic training, Group 2: receives plyometric training.

The primary goal of this RCT is to evaluate the effect of adding plyometric training after 12 weeks of standard intervention in patients aged 18-40 years who have undergone ACLR surgery. The primary question to answer is does adding plyometrics training to the standard rehabilitation program has superior effect in the improvement of muscular strength, dynamic balance and functional performance in ACLR patients. Participants will be divided into two groups. Group 1 receives standard program for 18 weeks, and Group 2 receives the same standard program for 18 months, but adding the plyometrics training at week 12.

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

The purpose of this study is to evaluate how well the KRONOS postoperative knee brace reduces pain and enhances recovery compared with the standard Breg T-scope hinged brace following anterior cruciate ligament (ACL) reconstruction knee surgery.
