Abstract:

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 still 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: Totally 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 (P < 0.05). During follow-up at 1 year after replacement, no significant differences in range of motion, muscle strength of quadriceps and hospital for special surgery knee score were detected in patients of both groups (P > 0.05). 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.
