Resumé

Partial knee arthroplasty (PKA) has shown obvious advantages compared to total knee arthroplasty, but survival of PKA from different institutions and registries has differed. In our institution, 695 consecutive Oxford medial PKAs were performed from 2002 to 2011 with mean follow-up of 4.6 years. The overall 10.7-year survival rate was 85.3% (95% CI: 78.7%-90.0%), and no difference in survival for gender and age younger or older than 60 years was found. One year after PKA, 94.3% were very satisfied or satisfied, as were 93.6% six years postoperatively. The revision rate was 7.3% (n=51), and the most common causes for revision were progression of osteoarthritis (n=16), aseptic loosening (n=11), and pain without loosening (n=10). Only 50% of patients revised for pain without loosening had a satisfactory outcome.
