 Background: In the recent decade, many primary total knee arthroplasties have

 been carried out in Iran and the number of revision cases is expected to rise with the

 aging population. The aim of this study was to report the outcome of revision surgery

 in the country and make a comparison between the outcome of revision and that of

 the primary arthroplasty.

 Methods: Retrospectively, each case of 19 consecutive revision total knee arthroplasties was matched individually with two cases of primary total knee arthroplasty

 based on gender and age (within 5 years) in order to compare the outcome in the two

 groups of revision and primary arthroplasties. Detailed demographic data, underlying

 diagnosis, patient-reported pain severity, and Knee Society score were recorded

 pre-operatively and in the third month after the surgery for each patient in the two

 groups. Using chi-square, fisher's exact, one-way ANOVA, independent, and paired

 t-tests, we compared the outcomes in two groups as well as in each group before and

 after the arthroplasty.

 Results: Knee pain was significantly decreased after the surgery in the two groups

 of revision (p = 0.031) and the primary (p < 0.001) arthroplasty. There was no statistically notable difference of post-operative pain between the two groups of revision

 and primary TKA. The Knee Society score remarkably increased in both groups after

 the surgery (both ps < 0.001). The differences of Knee Society scores before and after

 the surgery were calculated separately in each group and compared to show that the

 primary group had a better outcome (p < 0.001) rather than the revision arthroplasty


 Conclusion: Conclusion: Satisfactory outcomes were obtained in our revision total

 knee arthroplasties however, the primary arthroplasties had better results. The results

 of surgery appear to be closely related to the technical demands placed on surgeon.

 Because we have to deal with more cases of revision total knee arthroplasty in

 near future, more comprehensive risk factor assessment studies with large sample

 size are required for gaining better results.
