The Themoskin Knee Brace Open Flexion/Extension offers a flexible application with durable polycentric hinges that provide flexion and extension range of motion stops at selected degrees: 0, 10, 30, 50, 70, 90, and 110. Provides exceptional medial and lateral stability to the knee, while tracking range of motion through post-operative rehabilitation. Open wrap design offers easy application and can be adjusted to fit a wide variety of patients. Clinically proven heat therapy: only Thermoskin Thermal Supports have been clinically proven to increase subcutaneous skin temperature 2 - 3 fahrenheit for the optimal level of heat therapy. Thermoskin’s patented Trioxon® lining creates a micro-climate that maintains elevated skin temperature while still allowing the skin to ventilate for long-term user comfort. The spiral structure of the Trioxon® lining lifts moisture away from the skin and traps air within the lining to help prevent excessive perspiration.
