The increasing rate of primary total knee arthroplasties is followed by more revision cases in daily practice. The literature communicates us a revision-rate from 5 to 10% 10 to 15 years after primary implantation. We performed this study to understand benefits and also problems of total knee revision surgery and for improvement of these procedures.

Material and Methods

50 patients out of our collective from over 250 cases of total knee revision surgery (may 1995-may 2003) where we used the modular P.F.C. /P.F.C.Σ /TC3 system (DePuy Inc., Warsaw, Ind.). We examinated retrospectively (follow up 45+-13months) and compared scored results with international literature. Items were pre- and postoperative objectives like ROM, pain, stability, alignement, x-ray measurements and also patients general health status and satisfaction.


Significant (p<0,05) improvement in ROM, stability, pain, realignement, walking distance and scores (HSS/AKSS) but depending on patients general health status. Cruciate substituting devices showed better results. A higher complication rate than in primary total knee arthroplasty we have seen.


The use of a modular implant system cruciate substituting in total knee revision surgery by an experienced surgeon allows reliable early and mid-term results.
