Arthroscopic lateral release and the lateral patellar compression syndrome.

An isolated arthroscopic lateral release can provide dramatic relief of anterior knee pain in a select group of patients. We believe this procedure is indicated for patients with lateral patellar compression syndrome without significant chondrosis who have not responded to nonoperative treatment. During the procedure, care must be taken to perform a complete release and to achieve hemostasis. The postoperative rehabilitation emphasizes control of swelling, patellar mobilization, and quadriceps strengthening. We strongly agree with Schonholtz et al who report that the "lateral retinacular release is not a minor procedure and should not be performed simply because it may help and it can't hurt."
