Presentation
Pain localized mainly in the posterolateral aspect of the knee with reduction of terminal flexion and extension range of motion.
Patient Data
Mucoid degeneration of ACL and a pluriconcamerate ganglion with extra-articular extension into the popliteal fossa. The remaining objectivity is normal.
Case Discussion
Thickening of the anterior cruciate ligament from mucoid degeneration or the presence of ganglion cysts causes flexion deficit while the interfering tibial insertion ganglion causes extension deficit. Anterior cruciate ligament mucoid degeneration and ganglion cyst are two distinct non-traumatic injuries of the anterior cruciate ligament (ACL) that occasionally coexist.
They are usually asymptomatic and discovered incidentally. Occasionally, they may be responsible for chronic nonspecific pain, painful limitation of flexion and extension, and mechanical block.
