Matching degree between total knee prosthesis and tibial plateau in Chinese female patients
摘要
Abstract
Objective To assess the matching degree between total knee prosthesis and the tibial plateau in Chinese female patients.Methods One hundred and two female patients undergoing knee arthroplasty from August 2014 to July 2017 were enrolled.The tibial prosthesis was applied according to the tibial antero-posterior diameter (A/P)in 66 patients (group A),and according to the tibial medial-lateral diameter (M/L) in 36 patients (group B).Legacy PS (Zimmer,USA) total knee prosthesis was used for all patients.When the prosthesis cover rate was ＞ 75％,it was referred to matching;when the rate was＜75％,it was referred to mismatching.The range of motion (ROM) on 3 d,7 d and 3 month after surgery,the KSS score and the WOMAC score,infection around the prosthesis,deep vein thrombosis,pulmonary embolism,prosthetic cacothesis,dislocation,aseptic loosening were recorded and analyzed.Chi-square analysis and t test were used for statistic analysis.Results The matching rate of group B was significant higher than that of group A,but was significant lower than that reported in international literature.The extending ROM of group B (2.5°± 1.6°) was significant less than that of group A (-3.2°±1.5°) (P＜0.05).There was no significant difference in other indexes (P＞ 0.05).No complications were found in both groups.Conclusion The imported prostheses are designed according to the anatomy of Caucasians,which is quite different from Chinese tibial plateau A/P diameter and M/L diameter,especially in women.The modification of prostheses according to Chinese is necessary.关键词
