including cardiopulmonary and genitourinary complications, were all similar except a higher likelihood of returning back to operating room in the TKA group. (27.9% vs 12.4%; P < .01; Table I) TKA was an independent risk factor for reoperation (hazard ratio, 2.71; confidence interval, 1.66-4.44; P < .01). However, postoperative mortality was not associated with TKA (P 1⁄4 .77) or reoperation (P 1⁄4 .42) but with patient physiologic conditions (dyspnea, sepsis, emergent operation, high American Society of Anesthesiologists score, and dependent lifestyle; Table II). Conclusions: Outcomes of TKA demonstrated similar postoperative morbidity and mortality compared to AKA. Wound infection or dehiscence risks were equivalent. TKA demonstrated a higher rate of reoperation. However, neither TKA nor reoperation predicted postoperative mortality. Patients in stable physiologic condition without active infection can safely undergo elective TKA to maximize rehabilitation potential.
