Patellofemoral Joint Instability: A Review of Current Concepts

Patellofemoral Joint Instability: A Review of Current Concepts

The patellofemoral joint remains the enigma of orthopedics and sports medicine. Patellar dislocation is a common problem in the younger and athletic population and it is more disabling than cruciate ligament injuries. The pathology is often multifactorial and complex with no one factor being the sole defining etiology. The current management of patella dislocation has been linked with poor pati...

Patellofemoral Pain: Current Concepts

Patellofemoral pain (PFP) is common, especially in women who are physically active. The diagnosis can be challenging, as the etiology of PFP is complex and is unclear. The purpose of this paper is to discuss the current etiological understandings both microscopically and macroscopically and provide an overview for the evaluation and treatment. It is essential to approach each patient presenting...

Patellofemoral Joint Instability: A Biomechanical Study

Patellofemoral joint instability is a complex clinical problem. It may be a consequence of pre-existing anatomical abnormality or trauma. The objectives of this study were to use experimental mechanics to measure patellar stability and to quantify the effects of pathological abnormalities on patellar stability in vitro. Eight fresh-frozen cadaver knees were studied. The patellar stability was m...

Patellofemoral Arthroplasty: Current Concepts and Review of the Literature

Patellofemoral osteoarthritis (PFOA) can be associated with anterior knee pain, stiffness, and functional impairment. Some authors report that PFOA affects approximately 9% of patients older than 40 years with a greater prevalence in females. Etiology of PFOA is multifactorial and is related to the presence of abnormal stresses at the PF joint due to knee- and patient-related factors. The need ...
