Abstract

Arthroscopic deepening trochleoplasty is a less invasive trochleoplasty technique based upon the thin flap Bereiter technique. The indication corresponds the indications for opening deepening trochleoplasty. In fact are the indications for trochleoplasty not clarified, however in cases of severe symptomatic trochlear dysplasia, there is increasing approval of the procedure. Still deepening trochleoplasty is primary used for patients having recurrent patellar instability, based on the pathomorphology of severe trochlear dysplasia. Few studies has reported on trochleoplasty used in patients have chronic patellofemoral pain accompanying trochlear dysplasia. The arthroscopic trochleoplasty is a minimal invasive method and it seems to be more precise, with reduced risk of infection, less pain, faster rehabilitation, less risk of arthrofibrosis and the risk of cartilage flap fracture is significantly reduced. This chapter describes the procedure in detail. The ADT procedures has now been conducted in more than 150 knees (range 12 to 51 years). Two complications (DVT) have occurred. Eight knees have needed further surgery. In 2014 the indications for the procedure expanded to include patients having degenerative changed in the trochlea region and patients having chronic patellofemoral pain based severe trochlear dysplasia. The arthroscopic deepening trochleoplasty technique, with or without reconstruction of the medial patellofemoral ligament has been found to be a reproducible and a safe technique without serious complications.
