Intra-articular dislocation of the patella is a rare injury. Two types of intra-articular dislocations have been described in literature. In horizontal type, the patella has rotated on its horizontal axis. In the second type, the patella rotates on its vertical axis. These dislocations frequently are difficult to reduce by closed methods, and open reduction generally is required. We describe here a case of horizontal intra-articular dislocation of patella in a young 25-year-old male managed successfully by closed reduction.
