Abstract: ABSTRACT:Objective To investigate the perioperative and early-term efficacy of bilateral total knee arthroplasty (BTKA) in one-stage procedure. Methods Totally 93 patients operated with BTKA in one-stage procedure from 2003 June to 2005 June were followed up and the curative effect was determined with Hospital for Special Surgery knee-rating system (HSS). The complications were then analyzed. Results The mean postoperative HSS score was 89.6 (55~96 scores) and the excellence/good rate reached 95.7%(excellent in 74 cases, good in 15 cases, moderate in 2 cases, and poor in 2 cases). Except for the muscle power, the pain, joint function,range of joint movement (ROM), deformity, and stability were significantly improved after operation (P <0.05). The average ROM of knee was improved to 99.8(75-135) degrees after operation from 88.9(25-110)degrees before operation(P <0.01). Complications included deep vein thrombosis (n=2), incision fat liquidation (n=2), deep infection(n=1), urinary infection (n=1), and peroneal nerve palsy (n=1). No death was documented. Conclusion Bilateral total knee arthroplasty in one-stage procedure under secure conditions can be performed with good outcomes in selected patients without a definite increase in perioperative risk.
