Clinical presentation
Patients typically present with pain and swelling approximately 2.5 cm inferior to the medial joint space 1,2.
Radiographic features
Identifying the correct anatomical location is key to the diagnosis and the differential diagnosis.
MRI
bone marrow oedema on the tibial crest
soft tissue oedema surrounding the MCL at the point where the ligament meets the tibial crest
acute medial tibial crest (on average 8.1o lower crest angle compared to non-symptomatic)
