Abstract:
BACKGROUND: Total knee arthroplasty is one of the most effective and successful operations for the treatment of various end-stage or severe knee diseases.However,there is no consensus about routine patela resurfacing in total knee arthroplasty.OBJECTIVE:To investigate the efficacy of patelar arthroplasty in one-stage bilateral total knee arthroplasty for the treatment of knee osteoarthritis.METHODS:Patients undergoing bilateral total knee arthroplasty were selected from the Department of Orthopedic Surgery,Affiliated Hospital of Qingdao University in China between February 2013 and February 2014.They were randomly assigned to two groups.Patelar resurfacing group received patelar arthroplasty.Non-patelar resurfacing group did not receive patelar arthroplasty.RESULTS AND CONCLUSION:At 3,6 and 12 months folowing the surgery,no significant difference in Knee Society Score and range of motion of knee joint was detected between the two groups (P＞0.05).12 cases experienced anterior knee pain,including 4(13％) of the patelar resurfacing group and 8(27％) of the non-patelar resurfacing group.There were no complications such as prosthesis fracture,loosening,displacement,patelar fracture or patelar necrosis,and patelar prosthesis revision.Results verified that patelar arthroplasty and non-patelar arthroplasty have the same short-term effectiveness in one-stage bilateral total knee arthroplasty for osteoarthritis.
