[Arthroscopy in acute dislocation of the patella: a new surgical technique]

The adequate treatment for acute patellar dislocation is still controversial. The Authors describe a new surgical arthroscopic technique to repair medial retinaculum rupture, which is the most common lesion in the acute patellar dislocation. Compared to arthrotomy arthroscopic treatment eliminates post-operative pain and shows the same advantages in reducing recurrences.
