title: A "biologic technique" for the treatment of a disruption of the extensor mechanism after revision total knee arthroplasty: a case report.
abstract: A modified technique for the reconstruction of the extensor mechanism after revision total knee arthroplasty, is described. A medial gastrocnemius flap, in combination with in situ use of semitendinosus tendon autograft through intraosseous patellar tunnel, was used. The patient was followed for 2 years after the final reconstruction. After the procedure, the patient who previously had been dependent on a walker was able to walk without a cane. The above mentioned technique provided good functional outcome in our case.
