Background: Patellofemoral joint problems refer to a spectrum of conditions affecting the patellofemoral joint, which is the joint between the patella and femur. These conditions can cause pain and instability in the knee and affect an individual’s ability to perform daily activities. Patellofemoral joint problems commonly cause knee pain, particularly among young athletes and physically active individuals. This review article discusses current patellofemoral joint problems, including their epidemiology, pathophysiology, diagnosis, and management.
Current Concepts: Patellofemoral joint problems are presented as clinical symptoms of pain and instability.
Dividing the diagnostic criteria into anterior knee pain, patella instability, and patellofemoral arthritis is useful.
Anterior knee pain is diagnosed after excluding possible causes. Patellar instability is classified into recurrent dislocation, habitual dislocation (extension and flexion types), and permanent dislocation. Moreover, patellar instability can progress to the final stage of patellofemoral arthritis. Thus, patellar instability should be treated according to the Dejour criterion, and patellofemoral arthritis treatment requires artificial joint replacement surgery.
Discussion and Conclusion: The pathological mechanism of patellofemoral joint problems still needs to be properly established, and multifactorial causes make it difficult to treat patellofemoral joint problems. Accurate diagnosis is considered an essential factor for successful treatment.
