Purpose: The purpose of this study is to compare the clinical results and the rates of complication among three groups that received the simultaneous total knee replacement (TKR), one-week interval staged bilateral TKR, or several-months interval staged TKR.
Materials and Methods: We conducted a retrospective study of patients who had been diagnosed with bilateral degenerative osteoarthritis undergoing bilateral TKR from 2004 May to 2012 March. We divided patients into three groups which received simultaneous TKR (Group A, n=84), one-week interval staged bilateral TKR (Group B, n=124), or several-months interval staged TKR (Group C, n=65). Hospital for special surgery (HSS) score and the rate of complication were evaluated and compared.
Results: Mean postoperative HSS score showed significant improvement in the three groups. No difference in postoperative HSS was observed among the three groups (p=0.325). The complication rate in Group A was lower than that in Group B (p=0.049) and that in Group A was similar to that in Group C (p=0.786).
Conclusion: Group A had a better result than Group B and was similar to Group C in complication rate. One-week interval staged TKR can be good choice in patients with bilateral degenerative osteoarthritis.
