Tendon Structure and Treatment

The diagnosis and treatment of patellofemoral dys function, especially subluxation of the patella, remains controversial. Many authors feel conservative treat ment will give better long-term results than operative treatment. To aid in nonoperative treatment of patellofemoral conditions a dynamic patellar stabilizing brace has been developed. The brace applies an active, medially displacing force to the lateral border of the patella and maintains constant pressure during flexion, extension, and rotation of the knee. This brace consists of an elastic sleeve with a patellar cutout and two circum ferentially wrapped "live" rubber arms which apply dynamic tension to a crescent-shaped lateral patellar pad. An elastic circumferential counterarm maintains proper positioning of the pad and prevents rotation of the brace. The brace, superior to other methods of patellar splinting, is felt to be useful in the diagnosis of sus pected subluxation in patients without the classical stigmata of patellofemoral dysplasia. It has proven useful in the treatment of 39 cases of patellar sublux ation and 4 of patellofemoral arthritis. In a number of cases symptoms were completely eliminated with pro longed use of the brace. The brace is felt to be beneficial in conjunction with vastus medialis rehabil itation in patellar subluxation in growing children; in patients with mild or occasional subluxation, espe cially during specific activities; in persons with dislo cation or subluxation in which surgery is contraindi cated or must be delayed; and in acute subluxation. The brace may also be helpful in the prevention and treatment of chondromalacia and patellar tendinitis.
