Patellofemoral pain syndrome
Etiology is complex with many factors contributing to patellar dysfunction, such as imbalance of patellar tracking in extensor / flexor movements, excessive load on knee joint, dynamic or functional valgus alignment, weak hip abductors, and internally rotated femur or tibia. Other associations include hip, muscle, and quadriceps dysfunction, patellar hypermobility, or constricted patellar mobility.
Noninvasive multimodal management includes modification or avoidance of pain-causing activity, use of knee or foot orthoses, and patellar taping. Physical therapy offers several approaches aimed at reducing pain and improving patellar tracking. Pharmacological treatment of pain and other symptoms are generally short-term. Arthroscopic surgical treatment is not generally recommended.
