A. Harilainen et al., REVISION OF THE PCA UNICOMPARTMENTAL KNEE - 52 ARTHROSIS KNEES FOLLOWED FOR 2-5 YEARS, Acta orthopaedica Scandinavica, 64(4), 1993, pp. 428-430
We evaluated 52 unicompartmental PCA arthroplasties for primary (46) o
r secondary (6) arthrosis after 3 (2-5) years. Cementless fixation was
used in 35 femoral and in 28 tibial components. There were indication
s for revision in 11 cases. Conversion to a total knee had been perfor
med in 4 cases, and 1 tibial as well as 1 femoral component had been e
xchanged, mainly because of polyethylene wear with increasing deformit
y. 2 femoral components were loose and 1 had fractured.
