Abstract
Arthroscopic trochleoplasty (AT) was originally introduced in 2008 and is based upon the Bereiter thin flap trochleoplasty technique. It is mainly indicated in patients having patellar instability and high-grade trochlear dysplasia. The AT method is less invasive, and theoretically is the risk of infection and arthrofibrosis reduced compared to the open technique. Other advantages might also be less pain, faster rehabilitation, and less risk of cartilage flap fracture. This chapter is a detailed description of the procedure. The AT procedure has now been conducted in 115 knees in 99 patients, 72 females and 27 males, median age 20 (range from 12 to 57). For complications two deep venous thromboses have occurred. Eight knees needed further surgery. The AT technique, with or without reconstruction of the medial patellofemoral ligament, has been found to be a reproducible and safe technique without serious complications.
