Hemiarthroplasty of osteoarthritis of the knee joint with McKeever tibial plateau prosthesis

Abstract

The cases with osteoarthritis of the knee with persistent effusion were evaluated by X-ray at weight-bearing. Unilateral narrowing of the knee joint at weight bearing was assumed to cause instability and thrust of the knee joint at walking.
Six of these cases were treated by hemiarthroplasty with the modified McKeever tibial plateau prosthesis. At average 10.3 months of following-up period, clinical results were revealed two cases as excellent, three as good and one as fair, assessed by Weinfeld's method of evaluation of arthroplasty of the knee joint.
As early complication, occaisional hemoarthrosis was noted in one case, but late complications, such as sinking of the prosthesis, have not yet known.
