Recent projections expect the number of revision knee replacements performed to grow from 38,000 in 2005 to 270,000 by the year 2030¹. Although the results of primary total knee arthroplasty are well documented, with overall implant survivorship at 15 years greater than 95%² the results of revision procedures are not as well known. What if the revision TKR fails and what is the prevalence of failure of revision TKRs, the complications and re-operation rates? There are various studies which has either exclusively dealt with the causes or outcomes of revision with a particular prosthesis and survivorship analysis. The effectiveness of revision total knee replacement must be considered in the light of complications rates which could be either medical, orthopaedic surgery related complications or combination of both.

The purpose of this study was to evaluate the prevalence of complications, reoperation rates and outcomes in a single surgeon's series between 1984 and 2008.

Ninety nine index revision cases were studied. Incidences of surgical complications were 52.5%. The total reoperation rate was 34.3% whilst single re revision accounted for 19.9% whereas multiple re-revision incidences were 4%. The mean outcome in terms of Knee Society Score, Knee Society Function, and Knee society range of motion was statistically and clinically significant between pre operative and posts operative score at one year and remained consistent with time. These results suggest that modern revision total knee replacement are satisfactory operations and the outcomes perhaps can be improved if relatively simple strategies are followed by focusing these operations to specialized that accumulate enough experience from these demanding surgeries. Overall the results asserts that even in the hands of an experienced surgeon the complications do occur which is usually multi factorial, whilst in the light of complications and reoperation incidence the patients can be counselled thoroughly before the procedure.
