Results of Simultaneous Bilateral Total Knee Replacement: A Study of 1208 Knees in 604 Patients


Bilateral symptomatic knee arthritis is a common clinical problem. There are conflicting opinions as to the advisability of simultaneous sequential bilateral total knee replacement. Complication rates of primary unilateral knee replacement are well documented and there are several small series that compare the two techniques. The objective of this study was to identify the complication rate of simultaneous sequential bilateral total knee replacement in a large patient population. Over a 13-year period, 604 primary bilateral sequential simultaneous total knee replacements (1208 knees) were performed. Office notes and hospital charts were retrospectively reviewed to obtain age, sex, diagnosis, knee alignment, associated comorbidities, operative protocol, transfusions, and complications. The study results showed
5.1% local and 15.3% systemic complications and 0.7% mortality rate (none in the past 9 years). With appropriate patient selection and operative technique, patients who present with bilateral symptomatic knee arthritis can enjoy the benefits of simultaneous sequential bilateral total knee replacement without increasing their risks of complications.
