Abstract
BACKGROUND:Early knee ioint prosthesis is used to relieve severe pain of patients．With continuous modification，the knee joint prosthesis with high flexion has developed．OBJECTIVE：To compare the clinical outcome between fixed platform high—flexion prosthesis and rotating platform high-flexion prosthesis following total knee arthroplasty．DESIGN：Non-randomized concurrent control trial of patients．PARTICIPANTS：Thirty-four patients(50 knees)with severe osteoarthritis underwent total knee replacement in Department of Bone and Joint,Tianjin Union Medicine Center from January to December 2006．METHODS：Of 34 patients，16(25 knees)underwent fixed platform high-flexion prosthesis replacement(LPS flexion，Zimmer，USA)，and 18(25 knees)underwent rotating platform high-flexion prosthesis replacement(PFC sigma RPF prosthesis．Johnson & Johnson,USA)．MAIN OUTCOME MEASURES：Knee joint function was evaluated using Hospital for Special Surgery Knee Score (HSS)before and 2 weeks，1，3 and 6 months after surgery．In addition，range of flexion of the knee was observed at 6 months postoperatively．RESULTS：Thirty-four cases completed the treatment and were followed up for 6 months．HSS scores of patients undergoing rotating platform high-flexion prosthesis replacement were higher than fixed platform high·flexion prosthesis replacement group at 2 weeks postoperatively(P<0．05)，while no differences were found in HSS scores at 1，3 and 6 months after surgery(P>0．05)．In addition，there were no significant differences in the range of flexion of the knee at 6 months postoperatively[(130．4±15．2)°，(129．9±13．8)°，P>0．05]．CONCLUSION：Fixed platform and rotating platform high-flexion prosthesis replacement exhibit similar early effects on severe osteoarthritis．关键词
