The DonJoy Lateral J Patella Knee Brace is equipped with a tubular, lateral "J" buttress that runs alongside the knee. This knee brace can be worn for day-to-day activities and while playing sports; both in and out of the water. Intended for those suffering from lateral patellofemoral knee pain related to the following: lateral patellar subluxation and dislocations, lateral patellofemoral malalignment, patellofemoral maltracking and pain, and chondromalacia. It's designed to provide you with multiple treatment options to best suit your needs. Choose the knee brace material between Drytex and neoprene; and with or without hinges. Drytex allows for improved airflow while still giving ample support and compression. It's preferred by those in warm weather climates and individuals with neoprene allergies or irritations. Neoprene is a thicker, wetsuit-like material. It provides plenty of support and compression, and delivers a warmer option. Aluminum hinges offer enhanced stability and allow you to function with more confidence and comfort. Universal design allows the DonJoy Lateral J Patella Knee Brace to be used by both men and women.
