Abstract:

BACKGROUND: When patient presents bilateral degenerative knee osteoarthritis, one-stage or two-stage total knee arthroplasty (TKA) remains controversial at present. 
OBJECTIVE: To compare the outcomes of one-stage and two-stage bilateral TKA for bilateral knee arthritis.
METHODS: Patients with bilateral knee arthritis were treated in the First Affiliated Hospital of Soochow University in China from January 2005 to December 2008. They were assigned to one-stage group (n=68) and two-stage group (n=71). These patients were subjected to one-stage and two-stage bilateral TKA using Gemini MK II total knee system.
RESULTS AND CONCLUSION: Compared to two-stage group, operation time and length of hospital stage were shorter, mean blood transfusion was larger, and hospital charges were lower in the one-stage group. However, no significant differences in postoperative knee function, complications, and patients’ satisfaction were detected between the one-stage and two-stage groups. No osteolysis was observed surrounding the prosthesis during final follow-up. These data confirmed that one-stage bilateral TKA increased the amount of blood transfusion, but could save hospital charges, and reduce the length of hospital stay. Thus, one-stage TKA is a safe effective method to treat bilateral knee arthritis, and deserves application.
