Abstract
Unicompartmental knee arthroplasty (UKA), in addition to total knee arthroplasty (TKA), has been shown to be effective in the surgical treatment of knee osteoarthritis with appropriate patient selection. In clinical studies, it has demonstrated superior functional results with lower complication rates. In clinical practice, these advantages must be weighed against the disadvantage of an increased revision rate, especially in younger patients with sports and work activities. The aim of this study was to compare the functional outcome as well as the time to return to daily activities, work, and sports after revision of UKA to TKA with those of primary UKA and primary TKA using amatched-pair analysis. The study was based on amatched-pair analysis at two defined time points, always comparing 28patients who underwent either revision of aUKA to aTKA, primary UKA, or primary TKA. Patients completed the Oxford Knee Score, UCLA score, Knee Society score, and WOMAC score during standardized follow-up. In addition, postoperative patient satisfaction and return to activities of daily living, work, and sports were recorded in astandardized manner, and aclinical examination was performed. The four functional scores studied showed acommon trend in favor of UKA, followed by primary TKA and revision TKA. The differences between converted UKA and primary TKA were not significant. However, at 3.2years after the last surgery, the results of the converted UKA were significantly lower than those of the primary UKA. Return to work and sports tended to occur the earliest after UKA, followed by TKA and the revision group. All groups showed atendency to engage in low-impact sports. The functional results of revised UKA were significantly inferior to those of primary UKA based on a3-year follow-up. Return to work, sports, and activities of daily living tended to take longer after revision than after primary implantation of either aUKA or aTKA.
