Efficacy of Intraligamentous Steroid Injection in Pain Reduction and Knee Motion Improvement in Patients with Mucoid Degeneration of the Anterior Cruciate Ligament

Mucoid degeneration of the anterior cruciate ligament (MDACL) involves a chronic degenerative process that results in an enlarged ACL, potentially accompanied by synovial cysts, which could lead to impingement within the femoral condylar notch.Histologic studies have revealed mucoid and/or chondroid material intermingled within the ACL fibers. 1)Although the precise cause of MDACL remains unclear, it is hypothesized that inflammation following minor injuries or due to osteoarthritis could significantly contribute to ACL degeneration. 2)
