Arthroscopic Trochleoplasty Lars Blønd INTRODUCTION Pathogenesis Biomechanics have demonstrated that trochlear dysplasia significantly affects the kinematics of the patellofemoral (PF) joint and negatively influences the stabilizing forces of the patella.1,2…
Lateral Retinacular Release and Lengthening Elliot Sappey-Marinier Nathan White Elvire Servien INTRODUCTION Pathogenesis Lateral retinaculum is an important stabilizer of patella, and the role of lateral retinacular release (LRR) for…
Lateral-Facet Elevating Trochleoplasty Simon Donell Iain McNamara INTRODUCTION Pathogenesis Trochlear dysplasia is a known risk factor for patellar instability. Lateral elevation trochleoplasty was first described by Albee in 1919.1 He…
Tibial Tubercle Distalization Scott Smith David C. Flanigan Robert A. Magnussen INTRODUCTION Pathogenesis Recurrent patellar instability predominately affects young, active people and has been attributed to a combination of patient…
Lateral-Facet Lengthening Trochleoplasty Roland M. Biedert INTRODUCTION Pathogenesis Normal patellofemoral stability is guaranteed by the complex interaction of skeletal geometry, soft tissues, and neuromuscular control.1 The shape of the femoral…
Tibial Tuberosity Anteromedialization Osteotomy William R. Beach INTRODUCTION John Fulkerson, MD, described the anteromedialization (AMZ) of the tibial tuberosity in 1983.1 His landmark work blended two well-known procedures that had…
Lateral Patellofemoral Ligament Reconstruction for Medial Patellar Instability Shital N. Parikh Michael G. Saper INTRODUCTION Pathogenesis Lateral retinaculum contributes not only to medial restraint of the patella but also to…
Patellar Tenodesis Cecile Batailler Simone Cerciello Elvire Servien Christopher Butcher Philippe Neyret INTRODUCTION Pathogenesis Episodic patellar dislocation (EPD) is a disabling problem for some young and active people. The primary…
Surgical Considerations for Tibial Tubercle Osteotomy Jason Koh INTRODUCTION Pathogenesis Patellofemoral disorders are common in the general population and a frequent cause for orthopedic consultation. Patellofemoral pain has been reported…
Quadricepsplasty Techniques for Patellar Stabilization Daniel W. Green Elizabeth A. Arendt Colleen Wixted Meghan Price INTRODUCTION Pathogenesis Quadricepsplasty or quadriceps lengthening is a surgical procedure used to remove the deforming…
