Tourniquet Use in Anterior Cruciate Ligament Repair

The purpose of this study is to assess the intra-operative and post-operative effects of tourniquet use during ACL reconstruction. We hypothesize that: 1. Limited tourniquet use will not significantly impact arthroscopic visualization nor the time it takes to complete an ACL reconstruction. 2. Limited tourniquet use will lead to significantly less patient pain intra-operatively and in the immediate peri-operative period. 3. Patients who undergo an ACL reconstruction with limited tourniquet use will have earlier return of quadriceps functions as compared to those undergoing reconstruction with the use of a tourniquet.

Dynamic ACL Brace: In Vivo Kinematics

The purpose of this study is to evaluate the effect of the Össur Rebound dynamic ACL brace on knee kinematics evaluated using dynamic stereo X-ray (DSX) imaging during functional activities. Brace performance will be evaluated before and after ACL reconstruction.

5 Years' Follow-up Assessment of Surgical Repair for ACL Proximal Rupture

Isolated ruptures of ACL (anterior cruciate ligament) are ligament injuries that can be proximal, central or distal. Treatment of patients with proximal lesions should be graded. Functional treatment can be reserved for low-demanding patients in whom the practice level is limited and progression risk to a functionally unstable knee less marked. In athletes, the risk of a new sprain must be explained and the patient will choose functional treatment or surgical treatment. Surgical treatment generally involves ligamentoplasty at the expense of a knee tendon to replace the ruptured ACL. In the context of proximal ACL rupture, the patient can be offered surgical repair of the ACL. There are numerous studies on ACL ligamentoplasties results but literature is poor on modern ACL repair outcomes. In this context, this study aims to describe the relapse rate at 5 years of patients operated for a proximal ACL tear.
