The Knee Joint Complex A1 - Dutton, Mark PY - 2011 T2 - Dutton's Orthopedic Survival Guide: Managing Common Conditions AB - The knee joint complex includes three articulating surfaces, which form two distinct joints contained within a single joint capsule: the patellofemoral and tibiofemoral joint.1,2 One of the problems facing the knee joint complex is the fact that it was not originally designed for bipedal motion.3 Evolutionary modifications have allowed the knee to adapt to the major changes placed on it during functional demands.2 Despite these adaptations, however, the knee is one of the most commonly injured joints in the body.
