The Lenox Hill derotation brace in chronic post-traumatic instability of the knee

Nine Lenox Hill derotation knee braces have been fitted for post-traumatic ligamentous instability of the knee. Eight of the patients found it an effective appliance for preventing their knees giving way, and wear it regularly. We would recommend this brace for cases of post-traumatic instability of the knee when the ligaments are at fault and provided that internal derangements such as meniscal tears or loose bodies have already been treated.
