Presentation
Chronic knee pain. Incidental finding.
Patient Data
anomalous low signal ligamentous structure passing from fabella, running transversely across the popliteal fossa and integrating with the fibers of the semimembranosus tendon
abnormal intrasubstance increased fluid signal along with ACL fibers related to a chronic sprain
mild joint effusion
Low signal ligamentous structure passing from fabella, running transversely across the popliteal fossa and integrating with the fibers of the semimembranosus tendon.
Case Discussion
This entity referred to a ligamentous structure passing from fabella, running transversely across the popliteal fossa and integrating with the fibers of the semimembranosus, semitendinosus, and gracilis tendons.
Minor trauma to the knee joint leads to fibrosis of the band and impingement of the semimembranosus, semitendinosus, and gracilis tendons and causes posteromedial knee pain.
MRI can be used to assess the ligament complex in the posterior compartment and plays an important role in diagnosis and excluding impingement of the semimembranosus, semitendinosus, and gracilis tendons.
Knee arthroscopy can be used for establishing the diagnosis and conducting surgery.
