title: Revision of the PCA unicompartmental knee. 52 arthrosis knees followed for 2-5 years.
abstract: We evaluated 52 unicompartmental PCA arthroplasties for primary (46) or secondary (6) arthrosis after 3 (2-5) years. Cementless fixation was used in 35 femoral and in 28 tibial components. There were indications for revision in 11 cases. Conversion to a total knee had been performed in 4 cases, and 1 tibial as well as 1 femoral component had been exchanged, mainly because of polyethylene wear with increasing deformity. 2 femoral components were loose and 1 had fractured.
