This Donjoy knee brace provides dependable support for mild to moderate ACL and/or PCL, MCL and LCL instabilities. Donjoy knee braces use a patented "Four Points of Leverage" strap design to enhance overall knee stability during pivoting movements. This hinged knee brace has polycentric hinges that conform to the knee joint's natural motion for uninhibited movement of the knee. The Donjoy Playmaker has a low profile design for increased comfort. This product serves as an excellent return to sport knee brace or as an orthopedic knee brace for patients with arthritis, meniscus tears, or undergoing rehabilitation following an ACL reconstruction. Donjoy hinged knee braces use quality materials in their constuction, and this model is a great choice for a variety of orthopedic knee conditions.
The Drytex Playmaker, suitable for mild to moderate ACL, MCL and LCL instabilities, is a neoprene alternative constructed of a unique nylon core and polyester Lycra fabric that allows for improved airflow. The lightweight polyester-nylon weave fabric is ideal for patients who have neoprene-based irritations or allergies, or live in warm weather climates. Available with or without open popliteal cutout (opening behind the knee).
Four Points Of Leverage Design
The strap design of the Playmaker knee brace family enhances support of the knee joint, and in particular, the Anterior Cruciate Ligament. The straps apply Four Points of Leverage which combine to successfully apply a net differential posterior force, or constant posterior force to the tibia, which reduces the instability in the ACL. This Four Points of Leverage design is used on the Defiance III, Defiance, Armor, Female Fource, 4TITUDE, Legend, and Playmaker braces. ACL and PCL versions feature patented 4-point dynamic leverage system.
Point 1 Anterior: The first point of leverage is the anterior thigh cuff. It acts as a point for rotating the femur anteriorly.
Point 2 Posterior: The second point of leverage is the posterior calf cuff. It acts as a point for rotating the tibia posteriorly.
Point 3 Posterior: The third point of leverage is a posterior thigh strap, which is applied while drawing the hinge bars posteriorly on the knee.
Point 4 Anterior: Incorporating the fourth point generates the crucial opposing force. By tightening and affixing the anterior tibial strap, the hinge is drawn into proper position, and the tibia is rotated posteriorly.
