Trochlear dysplasia and the role of trochleoplasty

Robert F LaPrade et al. Clin Sports Med. 2014 Jul.

Abstract

The diagnosis and treatment of chronic patellar instability caused by trochlear dysplasia can be challenging. A dysplastic trochlea leads to biomechanical and kinematic changes that often require surgical correction when symptomatic. In the past, trochlear dysplasia was classified using the 4-part Dejour classification system. More recently, new classification systems have been proposed. Future studies are needed to investigate long-term outcomes after trochleoplasty.

Keywords: Patellar instability; Patellofemoral joint; Trochlear dysplasia; Trochleoplasty.
