Effect of Patellofemoral Arthroplasty on Patellar
Height in Patients with Patellofemoral
Osteoarthritis
Osteoarthritis (OA) in the knee is common, painful, and may be uni- or multicompartmental.
The compartment affected by arthritis may be due to trauma, malalignment
(varus or valgus), or in the case of patellofemoral OA, patella alta.
