Abstract
The Denham knee replacement is a relatively simple unconstrained prosthesis. The design ensures good alignment and full extension, but does not allow flexion beyond 90 degrees or tibiofemoral rotation. The results after eight years' experience have been assessed in four different ways in over 600 cases. They show that for the limited needs of the elderly arthritic patient, the Denham arthroplasty provides a high proportion of satisfactory results with an unusually low rate of late failure.
