Arthroscopic trochleoplasty is a keyhole procedure to improve the shape of the top of the groove where the kneecap runs, that is in cases of trochlear dysplasia.
- a groove that is more shallow than usual
- an absent groove where the region is simply flat
- an actual bump rather than a groove
The technique of arthroscopic trochleoplasty
|A marked trochlear 'bump' that does not allow the patella to engage with the upper part of the groove of the femur.||From a portal above the patella, the arthroscopic surgeon lifts up the delicate joint cartilage and re-shapes the bony bump below it.||Absorbable tapes are used to hold the white cartilage against the re-shaped bone until healing takes place.|
