The use of the McKeever metallic hemiarthroplasty for unicompartmental arthritis
RH Emerson and T Potter
We reviewed the results of sixty-one McKeever unicompartmental
arthroplasties performed by the senior one of us (T. P.) for osteoarthritis
of the knee. The average follow-up was five years (range, two to thirteen
years). Forty-four (72 per cent) of the arthroplasties were rated as good
to excellent. The average postoperative range of motion in these knees was
110 degrees. Six knees were rated as fair and eleven knees, as poor. The
poor results appeared to be caused by degenerative arthritis involving
ipsilateral compartments that had not been resurfaced with an implant.
