title: [Clinical curative effect of bilateral total knee arthroplasty in one-stage procedure].
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 approximately 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.
  
  
  CONCLUSIONS
  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.
