Lateral Lengthening and Lateral Release

Abstract

The lateral retinaculum is a complex, layered structure that is the primary constraint to medial translation of the patella. Patients can develop patellar hypercompression syndrome and arthritis of the lateral patellofemoral joint from an overly tight lateral retinaculum. Conservative treatments include physical therapy and bracing but if relief is not achieved, surgical treatment in the form of lateral retinacular lengthening or release may alleviate symptoms. This chapter provides a thorough background of the risks, indications, outcomes, and techniques regarding treatment of the lateral retinaculum.
