Post-injury painful and locked knee

Ioannis I. Daskalakis, Apostolos H. Karantanas


A 27-year-old female felt sudden pain on the lateral knee joint, following a rotational dance figure,  with subsequent locked joint. Physical examination on the following day disclosed tenderness along the lateral joint line and joint locking with an audible and painful "clunk" on extension. Magnetic Resonance (MR) images are shown (Figs. 1-5).
