- Abstract: PURPOSE: To compare the occurrences of perioperative complications of two anesthetic techniques (general anesthesia [GA] and spinal anesthesia [SA] in patients undergoing primary unilateral total knee arthroplasty (TKA). MATERIALS AND METHODS: Patients who underwent unilateral primary TKA due to osteoarthritis from January 2005 to January 2014 were retrospectively reviewed. They were divided into two groups: GA (n=490) and SA (n=746). The operation duration, length of perioperative stay in the operation room and occurrences of adverse events in postoperative 30 days (mean, 29.7±3.1 days) were compared. Before multivariate linear or logistic regression analysis, different baseline characteristics were adjusted in the statistical models. RESULTS: There were significant intergroup differences in mean age (GA, 68.4±7.2 years; SA, 70.7±7.5 years; p<0.001) and mCCI (GA, 3±1.4; SA, 3.2±1.5; p<0.001). The GA group required longer preoperative room time (+9.4 minutes; p<0.001), postoperative room time (+12.7 minutes; p<0.001), and postoperative hospital stay (+2.5 days; p=0.001) and had more surgical site infections (5 [1%] vs. 0 [0%]; p=0.005) and blood transfusion (205 [41.8%] vs. 262 [35.1%]; p=0.01). No differences in operative duration and other adverse events were identified. CONCLUSIONS: We should cautiously consider that GA may be associated with slightly increased preoperative and postoperative room times, postoperative hospital stay, transfusion and surgical site infection rates in primary unilateral TKA.
