摘要

AIM To compare rotating versus fixed-bearing Press-Fit Condylar(PFC)Sigma posterior stabilized(PS)total knee arthroplasty(TKA)with the new“J curve”femoral design in terms of clinical outcomes and anterior knee pain.METHODS We retrospectively analyzed 39 patients who underwent primary total knee replacement surgery for knee osteoarthritis using the PFC Sigma PS TKA with either fixed(FP group,20 cases)or rotating platform(RP group,19 cases)treated between 2009 and 2013 by the same surgeon.The two groups were homogeneous for age,gender,weight,American Society of Anesthesiologists status,preoperative clinical and functional scores,and prosthetic alignment at two years after surgery.We analyzed clinical outcomes score at two years follow-up using Knee Society Score(KSS),Knee Injury and Osteoarthritis Outcome Score(KOOS),Knee Performance Score,Short Form(SF)36,and anterior knee pain assessed by the Hospital for Special Surgery(HSS)patellar score.RESULTS No differences were found in KSS,Knee Performance Score,and SF-36 outcome scores.A statistically significant difference was found in the HSS Patella score objective(FP:22.36;RP:28.75;P<0.05),HSS Patella score total(FP:73.68;RP:86.50;P<0.05),and KOOS symptoms(FP:73.49;RP:86.44;P<0.05).CONCLUSION Rotating platform in PFC Sigma PS TKA appears to reduce the short-term incidence of anterior knee pain compared to the fixed platform.
