Torsion of an intra-articular lipoma as a cause of pseudo locking of the knee.
We describe a case of a painful locked knee caused by the torsion of an intra-articular lipoma and review the literature on this unusual condition. There are many cases of locked knee and of intra-articular lipoma but to our knowledge there are no previous documented cases of a torted lipoma being identified as a cause of locking.
