About this study
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.
Read the detailed description
Isolated ruptures of ACL (anterior cruciate ligament) are ligament injuries which lead to the most surgical interventions on the capsuloligamentous system of the knee. These ruptures can be proximal, central or distal.
Treatment of patients with proximal lesions should be graded and should take into account the patient's symptoms (feeling of instability), physical examination data, amount of residual ligament, sport practice, practice level, interval time since the initial trauma, work requirements… Functional treatment can be reserved for low-demanding patients in whom the practice level is limited and tprogression 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.
Functional treatment is variable, combining the use of splints, rehabilitation, muscle strengthening. The healing time is three months. Wearing a splint has not proven its effectiveness in preventing progression to complete rupture when resuming sport activities. If instability is revealed, it is then necessary to move towards ACL reconstruction 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 also be offered surgical repair of the ACL. There are numerous studies on ACL ligamentoplasties results but literature is poor on modern ACL repairs outcomes. Surgical repair of proximal rupture of ACL has experienced renewed interest in recent years thanks to the appearance of new fixing systems. Used in the 1980s, this technique was gradually abandoned in the mid-1980s following disappointing results for the benefit of autograft reconstruction techniques.
Few studies exist in the literature on long-term ACL repair surgery follow-up. In this context, this study aims to describe the relapse rate at 5 years of patients operated for a proximal ACL tear.
What is being measured
