When is Trochleoplasty a Rational Addition?Rush, Jeremy MD; Diduch, David MDSports Medicine and Arthroscopy Review: December 2019 - Volume 27 - Issue 4 - p 161–168 doi: 10.1097/JSA.0000000000000254 Review Article Buy Abstract Author InformationAuthors Article MetricsMetrics Trochlear dysplasia has been recognized as a dominant anatomic risk factor in patients with recurrent patellar instability. Sulcus-deepening trochleoplasty is a very effective and powerful procedure for correcting trochlear dysplasia and, specifically, eliminating the supratrochlear spur. However, it must be emphasized that trochleoplasty is not appropriate for patients with mild trochlear dysplasia or those without a large supratrochlear spur or bump. We discuss the characteristics and classification of trochlear dysplasia and discuss specific indications for sulcusdeepening trochleoplasty.
