Who the DonJoy Defiance suits
For people with moderate to severe ACL or PCL instability, after ligament reconstruction, for hyperextension, or for prophylactic use in sport. The low-profile frame fits under clothing and uniforms. A clinician measures the leg and specifies the hinge.
This kind of device is prescribed and fitted by a clinician. An enquiry starts that conversation. It is not a purchase.
