Fig. 3From: Intraarticular arthrofibrosis of the knee alters patellofemoral contact biomechanicsPatellofemoral contact force at each adhesion state (and across all flexion angles) was significantly different from the other adhesion states (P ≤ 0.007). Combined anterior interval adhesions resulted in the highest contact force followed by isolated suprapatellar adhesions, isolated anterior interval adhesions, and the no adhesions stateBack to article page
