Fig. 2From: Intraarticular arthrofibrosis of the knee alters patellofemoral contact biomechanicsSchematics of the testing setup. Patellofemoral contact force was measured with a thin-film pressure sensor in response to simulated anterior interval, suprapatellar pouch, and combined anterior interval and suprapatellar pouch adhesions (fasteners) at a 0° and b through a range of knee flexion angles spanning 0°–90°Back to article page
