Effects of Immobilization on the Sh... Nov 13, 2009
The tissues that experience adverse effects include connective tissue (joint capsule, ligaments, joint capsule), muscle, and articular cartilage ... Because the articular cartilage (thin layer of cartilage on the end of long bones) is solely dependant on movement to provide nutrients and lubrication to the joint, immobility causes articular cartilage to become thinner with possible necrosis (death of tissue) with extended periods of immobilization.
