The effect of stem design on end-of-stem pain in revision total knee arthroplasty.

A series of 143 revision total knee arthroplasties was evaluated using a Knee Society clinical score, radiographic assessment, and satisfaction questionnaire. Patients completed a pain drawing showing the location and severity of pain they experienced at 2 years follow-up. Two stem designs were used: a solid, fluted cobalt chrome stem (group I) and a slotted titanium stem (group II).
