Recently, medial patellofemoral ligament reconstruction has gained popularity as a treatment modality for recurrent patellar instability.2-6 Patients who have failed surgical interventions including lateral release, medial patellofemoral ligament reefing, and distal realignment may be good candidates for medial patellofemoral ligament reconstruction. The anatomy and biomechanics of the medial p...

Tibial tuberosity osteotomy (TTO) is a well-described treatment option for a broad range of patellofemoral joint disorders, including patellofemoral instability, patellar and trochlear focal chondral lesions, and patellofemoral arthritis. The purpose of this article is to review the evolution of the TTO procedure, from the original Hauser procedure to the current anteromedialization procedure, ...

Chronic patellofemoral instability can be a disabling condition. Management of patients with this condition has improved owing to our increased knowledge of the functional anatomy of the patellofemoral joint. Accurate assessment of the underlying pathology in the unstable joint enables the formulation of appropriate treatment. The surgical technique employed in patients for whom non-operative m...

Patellofemoral problems often begin with instability in young patients and become progressively disabling. Effective treatment requires understanding a complex combination of knee alignment, soft tissue influences on patellar tracking and stability, joint forces and the condition of articular surfaces. Management of patellofemoral conditions usually begins with directed physical therapy, variou...

We report an extremely rare case of both recurrent lateral patella dislocation and medial patellofemoral instability, following prior operations to correct patella maltracking. Manual translation of the patella revealed medial and lateral instability with a positive apprehension sign. 3-D computer modelling of kinematics based on MRI data demonstrated that the patella deviated laterally at full...

Imaging in patellofemoral instability confirms the diagnosis and guides treatment. It is essential to the accurate diagnosis of the root causes and their adequate treatment. A structured approach must be used to identify the factors causing instability, and more than 1 imaging modality may provide similar information. This article revises the acute findings and the abnormalities present in the ...
