Data on 4,554 patients showed same-day bilateral total knee arthroplasty did not correlate with an increase in the incidence of single or multiple manipulation under anesthesia and stiffness-related reoperation rates, according to study results.

Researchers analyzed institutional data for 3,175 patients who underwent same-day bilateral total knee arthroplasties, 153 patients who underwent same-admission staged bilateral TKAs and 1,226 patients who underwent staged bilateral TKAs within 1 year. They tabulated patient demographics, comorbidity profile, Charlson-Deyo index and range of motion at different time points. The minimum follow-up after first manipulation under anesthesia was 1 year.

Results showed that overall 2.2% of patients who underwent bilateral TKA needed manipulation under anesthesia. Investigators noted groups had similar rates for at least one manipulation under anesthesia (same-day bilateral TKA 2.2%; same-admission staged bilateral TKAs 2% and staged bilateral TKA 2%). However, patients who underwent same-day bilateral TKA had a higher percentage of bilateral total knee involvement (same-day bilateral TKA: 2%; same-admission staged bilateral 0.7% and staged bilateral TKA 0.3%). Groups had similar single manipulation under anesthesia rates (same-day bilateral TKA: 96.2%; same-admission staged bilateral TKA 100%; and staged bilateral TKA 89.3%). Groups that were manipulated had similar rates of no revision and revision reoperation. – by Monica Jaramillo
