Biomechanical Determinants of Different Rehabilitation Protocols for ACL Reconstruction

Study Overview
=================
Brief Summary
-----------------
Purpose of the study is to investigate the effects of the criterion rehabilitation protocol versus accelerated rehabilitation protocol on the biomechanical determinants of the quality of performance and risk of reinjury.

Eligibility Criteria
-----------------
Inclusion Criteria: Amateur male athletes who underwent ACLR surgery with an autologous hamstring (HS) graft. Ranging in age from 18 to 35 years. Underwent a pre-operative rehabilitation program with minimal knee effusion, full Extension, good patellofemoral mobility Ability to actively control the quadriceps. Exclusion Criteria: ACLR with any graft other than a hamstring graft ACL revision surgery associated medial or lateral ligamentous injuries previous meniscectomy or meniscal repair simultaneous meniscectomy or meniscus repair with the ACLR cartilage damage.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: criterion-based rehabilitation protocol<br>It's a three phases rehabilitation protocol with a goal-based progression which include a three criterion based postoperative phases: (1) impairment phase, (2) sport-specific training phase and (3) return to play phase. Patients can start with the next phase only if specific goals of the previous phase are achieved | Other: rehabilitation protocol<br>* rehabilitation protocols after ACLR have been described, aiming to improve muscle strength and knee stability through muscle strengthening exercises in addition to exercises to improve joint proprioception<br>|
| Active Comparator: accelerated rehabilitation protocol<br>It's a four phases rehabilitation protocol mainly based on the remodeling process of the graft., emphasizing full passive knee extension, immediate weight bearing as tolerated and functional exercises | Other: rehabilitation protocol<br>* rehabilitation protocols after ACLR have been described, aiming to improve muscle strength and knee stability through muscle strengthening exercises in addition to exercises to improve joint proprioception<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dynamic knee valgus during Single leg landing-jump test using kinovea software | From the coronal plane, dynamic knee valgus is the angle between femoral longitudinal axis and the extension of the longitudinal tibial axis. | 15 min | 
| Lateral trunk flexion during Single leg landing-jump test using kinovea software | From the coronal plane, trunk lateral flexion angle is the angle between the vertical median axis of the body and the longitudinal median axis of the upper trunk | 15 min | 
| knee flexion angle during Single leg landing-jump test using kinovea software | From sagittal plane, knee flexion angle is the angle between the longitudinal axis of the femur and the extension of the longitudinal axis of the tibia | 15 min |
