Background:There is limited literature on the success of simultaneous twosurgeon bilateral total knee arthroplasty (TKA), especially at nonuniversity hospitals where it could be argued that most joints are replaced. The purpose of this study was to determine whether selective patients can safely undergo this technique at nonuniversity hospitals and if our clinical results were comparable to published literature from university hospitals.
Methods:Forty-four patients who underwent simultaneous TKA were retrospectively reviewed between 2003 and 2009. All the surgeries were conducted by experienced arthroplasty surgeons (n ¼ 40-50 TKAs annually). At final follow-up, patients were administered a Knee Society Clinical Rating System (KRCRS), the Oxford Knee Score, a nonvalidated in-house satisfaction survey, and functional discrepancy survey.
Results:The mean age was 65.3 (range, 42-88) years. Mean follow-up period was 5.1 (range, 2.2-8.8) years. The latest mean KSCRS pain was 46.9 points, KSCRS function was 85.8 points, and Oxford Knee Score was 42.7 points. In terms of satisfaction, 93% were extremely or very satisfied. With limb function discrepancy, 98% rated as equal or close to equal in function. Kaplan-Meier analysis revealed similar survivorship at 5.1 (97.7% vs. 100%) years. There was an increase in complication rates within the first 2 yr and then a steady decrease as we gained more surgical experience. There were no significant differences (P > 0.05) in outcome between symmetric and asymmetric groups.
Conclusions:Simultaneous techniques are safe in the hands of experienced high-volume arthroplasty surgeons in a community hospital setting.
Background:This is an updated systematic review of the quality of life (QOL) scales being used in hemiarthroplasty research. The principal aim is to determine optimal choices for use in daily clinical practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
