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...

DesignProspective, singleblind, randomisedclinical trial. Setting Single centre trial within a community setting in Brisbane, Australia. Participants 179 participants (100 women...

Anterior knee pain is common in children and adolescents. Evaluation and management is challenging and requires a thorough history and physical exam, and understanding of the pediatric skeleton. This article will review common causes of chronic anterior knee pain in the pediatric population with a focus on patellofemoral pain.

Patellofemoral pain syndrome (PFPS) is the most common cause of knee pain in the outpatient setting. It is caused by imbalances in the forces controlling patellar tracking during knee flexion and extension, particularly with overloading of the joint. Risk factors include overuse, trauma, muscle dysfunction, tight lateral restraints, patellar hypermobility, and poor quadriceps flexibility. Typic...

We report the mid-term results of a new patellofemoral arthroplasty for established isolated patellofemoral arthritis. We have reviewed the experience of 109 consecutive patellofemoral resurfacing arthroplasties in 85 patients who were followed up for at least five years. The five-year survival rate, with revision as the endpoint, was 95.8% (95% confidence interval 91.8% to 99.8%). There were n...
