The DonJoy Hinged Air is designed to treat and ease pain associated with patellofemoral malalignment, chondromalacia and tendonitis plus medial/lateral instabilities and post-operative meniscectomies. The brace features an inflatable pneumatic buttress for medial, lateral or full patellar support, thus the reference to “air” in it’s name. It is constructed with Drytex, a neoprene alternative that allows for improved air flow.
