Patellofemoral instability not only involves lateral patellar dislocation, patellar mal-tracking or subluxation but can also cause a limiting disability for sports activities. Its underlying causes are known as morphological anomalies of the patellofemoral joint or the mechanical axis, femorotibial malrotation, variants of the knee extensor apparatus, and ligamentous insufficiencies often accom...

PURPOSE To conduct a systematic review of meta-analyses comparing nonoperative and operative treatment of patellar dislocations to elucidate the cause of the variation and to determine which meta-analysis provides the current best available evidence. METHODS A systematic review of the literature to identify meta-analyses was performed. Data were extracted for patient outcomes and recurrent di...

The management of osteoarthritis of the knee associated with patellar instability secondary to external tibial torsion > 45 degrees is challenging. Patellofemoral biomechanics in these patients cannot be achieved by intra-articular correction using standard techniques of total knee replacement. We reviewed seven patients (eight knees) with recurrent patellar dislocation and one with bilateral i...

The medial patellofemoral ligament has been recognized as the structure primarily responsible for preventing patellar subluxation or dislocation.1-3 Anatomic dissection studies identified the medial patellofemoral ligament as a band of tissue connecting the femoral medial epicondyle to the proximal part of the medial edge of the patella (Figure 1).1-6 Imaging studies7-11 and surgical exploratio...

It has been suggested that recurrent dislocation, subluxation, and functional instability due to patellofemoral pain are experienced by 30% to 60% of patients with post-traumatic patella instability who are managed with non-surgical methods [1-3]. Recently, the medial patellofemoral ligament (MPFL) has been recognized as the most important ligamentous stabilizer for preventing lateral dislocati...

BACKGROUND The treatment of acute patellar dislocation in children is controversial. Some investigators have advocated early repair of the medial structures, whereas others have treated this injury nonoperatively. The present report describes the long-term subjective and functional results of a randomized controlled trial of nonoperative and operative treatment of primary acute patellar disloca...

Intra-articular patellar dislocation due to acute trauma is considered a rare presentation and less commonly encountered in practice than extra-articular dislocation. This case study presents type 2 inferior of the patella an elderly patient which was successfully reduced managed non-operatively.
