Hyperextension complicating total knee replacement

An elderly man with bilateral total knee replacements had an unusual hyperextension probelm complicating one knee prosthesis. A new type of orthosis which was fitted to the patient corrected the hyperextension. The management of the patient is described. The goal of treatment was to help this man become ambulatory and independent in activities of daily living. He progressed sufficiently to return to his own apartment in the city where he lives alone.
