Giant anterior cruciate ligament lesion with destruction: operative management

Abstract

We present a case report of an unusual giant lesion of anterior cruciate ligament (ACL) causing destruction and requiring reconstruction of ACL. A case report of a 32-year-old male patient presented to orthopedics outpatient clinic with 2 years history of right knee instability and clicking symptoms with no history of an obvious injury. Magneric resonance imaging showed a giant lesion occupying all ACL structure in the knee with 30×15×15 mm dimensions. The patient had an arthroscopy and it showed destruction of ACL, which required ACL reconstruction in the same sitting. Biopsy results showed a chronic non-specific inflammatory synovial epithelial tissue with increased vascularity and thickened wall vessels.
