Designed to give you the comfort of an elastic support with the therapeutic properties of heat without the perspiration associated with neoprene. These supports are ideal for knee sprain or strain, and offer treatment for ACL, LCL, MCL, and PCL sprains. Recommended for swollen or tender knees resulting from sprains, strains, sports injuries, or postoperative treatments for Osgood-Schlatter Disease, as well as patellar instability. Prostyle retains heat to help keep muscle loose. Wrap design allows for an easy fit.
