Abstract:

BACKGROUND: Patients with knee arthroplasty mostly had bilateral lesions. It is still controversial to perform simultaneous bilateral surgery or unilateral arthroplasty. The focus of controversy is that bilateral arthroplasty of the same period can get a real upgrade of the repair effect if it does not increase the risk of surgery. There have always existed controversies.
OBJECTIVE: To comparatively analyze simultaneous bilateral and unilateral arthroplasty from aspects of safety, economy and effects.
METHODS: 118 patients suffering from severe bilateral knee osteoarthritis and treated by total knee arthroplasty in the First Affiliated Hospital of Anhui Medical University from April 2011 to April 2014 were divided into simultaneous bilateral arthroplasty group (n=47) and unilateral arthroplasty group (n=71). Variables reflecting safety, economy and effects were set up and data were collected and analyzed.
RESULTS AND CONCLUSION: There was no evident difference in safety between simultaneous bilateral arthroplasty and unilateral arthroplasty groups (P > 0.05). In economy and effect, simultaneous bilateral arthroplasty group was significantly better than unilateral arthroplasty group (P < 0.05). These results suggest that with the same surgical management level, if the patient could resist, simultaneous bilateral surgery should be more welcomed, while performing simultaneous bilateral surgery in patients with preoperative cardiovascular diseases should be decided carefully. Patients with diabetes mellitus preoperatively should be guarded against postoperative infection.
