Objective To compare domestic T-free knee prosthesis with the similar imported prosthesis in preliminary clinical results for early follow-up.Methods From July 2008 to December 2009,35knees of 25 patients were implanted with domestic T-free knee prosthesis,including unilateral TKA in 15 cases and bilateral TKA in 10.Deformity included flexion contracture in 19 cases with 25 knees,varus deformity in 11 with 18 knees,valgus deformity in 4 with 5 knees.The preoperative average ROM was 75.11°±27.68°,the mean points of Knee Society Score(KSS)were 17.88±14.37,and the average points of KSS function scores were 21.62±21.27.In the same period,all 27 cases with 39 knees operated by the same surgeon were implanted the similar imported prosthesis,and they were set for control group to do the retrospective cohort study.The patients of two groups who completed follow up had no statistical differences in age,BMI and preoperation ROM(P>0.05),but they had statistical differences in pre-operation KSS scores and pre-operation KSS function scores(P<0.05).Results The domestic prosthesis group's average follow-up time were 14.92±8.32 months and had no statistically different with the control group's 15.42±9.87 months(P>0.05).The mean postoperation knee ROM of domestic knee prosthesis group was 107.53°±18.32° in 14.92±8.32months follow-up,which did not differ with that of the imported group 112.84°±9.76°(P>0.05).There was no statistical difference in KSS scores between the domestic 86.71 ±9.78 and the imported group 86.68±6.01,and no difference in KSS functional scores was found between the domestic 65.88±25.01 and the imported knee prosthesis 71.35±16.74(P>0.05).The satisfaction rate after TKA was 95.8%(23/24)in domestic knee prosthesis group.Conclusion The domestic T-free knee prosthesis was commensurate with the similar imported knee prosthesis in preliminary clinical results for early follow-up.
