[Posttraumatic osteoarthrosis in a patient with chronic anterior cruciate ligament rupture. Case report and review of the literature].

Abstract

Anterior cruciate ligament (ACL) rupture is a very important epidemiological pathology in our environment. It has a peak incidence between 16 to 39 years of age. It is estimated that between 70-84% of ACL injuries are non-contact. The "no return" position describes the knee in valgus, femoral external rotation, tibial internal rotation and semiflexion, promoting injury to this ligament. Geometric measurements of the knee have been associated with an increased probability of non-contact ACL injury. The management of ACL tears is divided into two: conservative treatment and surgical management. Early OA (osteoarthritis) is the most common consequence of an ACL tear. We present the case of a 35-year-old patient with an inveterate ACL rupture of 10 years of evolution. With conservative management initially that progresses to knee instability and pain in the medial and lateral joint line as well as increased volume and functional limitation. After diagnostic studies, it was decided to perform diagnostic-therapeutic arthroscopy and continued close follow-up for associated pathology.
