The timing of performing knee arthroplasties in bilateral osteoarthritic knees remains controversial. Our aim was to compare one-stage with two-stage bilateral knee arthroplasties (TKA).

Between November 2004 and April 2008, 128 patients (72 female and 56 male) underwent one-stage bilateral TKAs. Another group of 115 patients that underwent two-stage procedures during the same period formed the control group. All patients received the same type of anaesthesia. Study parameters included age, weight, medical co-morbidities, length of hospital stay, blood loss, post-operative complications and functional outcome.

There were no significant differences between the two groups. Co-morbidities and functional outcome based on the Knee Society Score were similar in both groups. In the one-stage group the length of hospital stay and blood losses were higher than the two-stage group; however less than double compared to the two-stage group. The early post-operative complications were higher but not statistically significant in the one-stage group.

Despite the fact that the early post-operative complications are slightly higher in the one-stage group, this particular method is an effective way of dealing with bilaterally osteoarthritic knees. It offers excellent functional outcome at a reduced cost
