Superior Comfort and Durability The Wraparound Knee Stabilizer brace offers flexible medial and lateral spiral metal stays which allow for good support but is less aggressive than the dual action metal hinges of the hinged knee braces. Adjustable straps provide support, proper fit and comfort. This brace is recommended for ACL/PCL Sprains, Patella Pain, Medial/Lateral, Collateral Instability as well as any joint instability related to sprains or strains. The brace is made of 3/16" thick neoprene with an open back. Elastic straps provide non-slip grip during use preventing the knee brace from sliding down the leg. The Patellar opening provides for positioning and comfort. Brace has upper and lower circumferential straps w/ finger loops and pull tabs and special stress covers over the center, proximal and distal hinge for reinforcement. Additional benefits of our knee brace include bound edges for prevention of fraying which provides a longer lasting knee brace.
