BACKGROUND:The safety and efficacy of simultaneous bilateral total knee replacement or selective unilateral total knee arthroplasty in patients with severe osteoarthritis of the knees are stil controversial. OBJECTIVE:To compare safety and clinical efficacy of patients with osteoarthritis knees after simultaneous bilateral total knee replacement or selective unilateral total knee replacement. METHODS:Total y 60 cases with severe osteoarthritis of the knees (90 knees) undergoing total knee replacement were divided into unilateral total knee replacement group (n=30, 30 knees), and the simultaneous bilateral total knee replacement group (n=30, 60 knees). RESULTS AND CONCLUSION:There was no significant difference in the incidence of other complications such as infection, mortality, pulmonary embolism in patients of both groups (P>0.05). The incidence of cardiovascular complications, postoperative blood loss and blood transfusion were higher in the bilateral knee group than in the unilateral knee group (P0.05). However, Visual Analogue Scale scores were significantly lower in the bilateral knee group than in the unilateral group (P<0.05). These data indicated that the risk of cardiovascular complications was high in patients receiving bilateral total knee replacement. Patients with severe cardiovascular disease should avoid simultaneous bilateral total knee arthroplasty.
