The Performance Wrap Knee Support is the best all-around knee support available for more than one type of knee problems you may have, including patellofemoral pain (runner’s knee), patellar dislocation and subluxation, mild ostheoarthritis, patellar tendonitis (jumper’s knee) and meniscus pain. A four-way tension system provides a custom fit and excellent compression. Wraparound design is easy to wear and less bulky than hinged supports. Neoprene construction retains natural body heat and stays in place during swimming or other water activities. Available in S/M or L/XL. S/M fits up to 22” (56cm) thigh with a 17” (43cm) calf. L/XL fits up to 27” (68cm) thigh with a 20” (50cm) calf.
