The Influence of the Changes of Tibial Posterior Inclination on the Joint Function of Elderly Patients with Diabetes Complicated with Knee Osteoarthritis after Unilateral Condylar Replacement
[Objective]To investigate the effect of the change of tibial posterior slope(PTS)after unilateral condylar arthroplasty(UKA)in elderly patients with diabetes combined with knee osteoarthritis on joint activity.[Methods]The clinical data of 96 elderly patients with diabetes combined with knee osteoarthritis who received UKA in our hospital from June 2020 to June 2022 were retrospectively analyzed,and the change value of PTS(△PTS)before and after surgery was calculated.According to△PTS,they were divided into PTS reduction group(△PTS<-2.5°,n=36),PTS slight reduc-tion group(-2.5°≤△PTS<0°,n=42),and PTS increased group(△PTS≥0°,n=18).All patients were followed up for at least 12 months after surgery,and the postoperative range of motion(ROM),maximum flexion angle(MFD),Knee Society Clinical Score(KSS-C),Knee Society Functional Score(KSS-F),and incidence of postoperative complications were compared among each group of patients;Pearson correlation analysis was used to examine the correlation between △PTS and postoperative ROM,MFD,KSS-C,and KSS-F.[Results]The postoperative ROM,MFD,KSS-C,and KSS-F of pa-tients in the PTS reduction group were higher than those in the PTS slight reduction group and PTS enlargement group(P<0.05),PTS was negatively correlated with ROM,MFD,KSS-C,and KSS-F(P<0.05).There was no statistically sig-nificant difference in the incidence of postoperative complications among patients in each group(P>0.05).[Conclusion]For the elderly patients with diabetes and knee osteoarthritis,the proper reduction of PTS after UKA can significantly im-prove the knee joint function and improve the quality of life of patients.
