Abstract

Management of recurrent lateral patellar dislocation (LPD) remains difficult and controversial, despite an expansion of knowledge. With the advancement of medicine, an understanding of known anatomical risk factors of LPD, including patella alta and increased tibial tubercle (TT)–trochlear groove distance, now guide present-day management. However, this is not without drawbacks. Current measurements of anatomical risk factors cannot be considered universal, and it is, therefore,important to consider each case individually. The focus of this article is to highlight the history of patellar instability risk factors associated with TT osteotomy, as well as present-day operative management, which aims to restore normal biomechanics. Our goal is to provide a clinical framework to help clinicians approach surgical management of LPD. Operative versus non-operative management will be discussed in another article. The included case studies will aid in the understanding of patients with patellofemoral instability, presentation, and the clinician’s approach to management, in addition to showcasing the ongoing challenges in treating patellar instability.
Keywords: Patellofemoral joint; patellar instability; lateral patellar dislocation; patella alta; tibial tubercle distalization; tibial
tubercle osteotomy.
