Villa JM, et al. - This study was attempted to determine how perioperative outcomes and/or rates of adverse events were influenced by the timing of the second arthroplasty. Between 2010 and 2016, researchers retrospectively examined a consecutive series of 670 primary staged bilateral total hip/knee arthroplasty done by 2 surgeons at a single institution. For each pair of hips or knees, the days between both arthroplasties were estimated. Researchers assessed demographics and LOS, discharge disposition, adverse events (ie, nausea, pulmonary embolism), and transfusion rates. There were no significant differences in outcome comparisons using either 90 or 180 days thresholds. The results showed that staging the second arthroplasty more than a year apart from the first one appears to offer better LOS and rates of hospital adverse events, transfusions. Though, unless individuals are willing to wait a year between surgeries, the data also imply no raised risk in regards to adverse events when proceeding before or after 90/180 days.
