Modified endoscopic release of gastrocnemius aponeurosis.

Recession of the gastrocnemius aponeurosis is the operation of choice in the case of isolated gastrocnemius contracture, because it addresses the major deforming force without weakening the entire musculotendinous unit. Endoscopic recession of the gastrocnemius aponeurosis has been proved to be effective but can be associated with the wrong level of release, incomplete release, sural nerve injury, or a palpable gap at the aponeurosis. A modification of the endoscopic technique is described to provide solutions to these potential problems.
