Ganglion cyst of the posterior cruciate ligament associated with osteochondritis dissecans of the medial femoral condyle: A case report

Year: 2026

Type: article

Abstract: Ganglion cysts arising from the posterior cruciate ligament (PCL) of the knee are rare, and their aetiology remains unknown. In this case, we found a ganglion cyst of the PCL concomitant with osteochondritis dissecans (OCD) of the medial femoral condyle (MFC). We presume that unstable OCD fragments of the MFC repeatedly irritate the PCL fibres connected to the lesion, and that this repetitive minor trauma and subsequent continuous tissue reaction may account for the development of a ganglion cyst of the PCL. We thus performed arthroscopic excision of the ganglion cyst of the PCL and OCD lesion, and osteochondral autograft transplantation. No ganglion recurrence was observed on magnetic resonance imaging at 12 months postoperatively and no symptom recurrence was observed during the final follow-up at 24 months postoperatively. We thus speculate that the pathogenesis of ganglion cysts in the cruciate ligament involves repetitive minor trauma and a subsequent continuous tissue reaction.
