Intra-articular patellar dislocation due to acute trauma is considered a rare presentation and is less commonly encountered in practice than extra-articular patellar dislocation. This case study presents a rare type 2 inferior dislocation of the patella in an elderly patient which was successfully reduced and managed non-operatively.
