Patellar Subluxation

Topic Overview

A subluxation is a partial dislocation. The kneecap, or patella, can sublux out of its normal track when it is not firmly held by the surrounding tendons and ligaments or when the joint is structurally unsound.

A patellar subluxation feels like the kneecap is shifting or jamming out of place. Usually, a subluxated patella returns to its normal position by itself. But repeated incidents can damage the patella's cartilage underside or stretch its connective ligaments.
