近端胫腓关节解剖形态与膝骨关节炎发生的相关性研究OA

Objective To propose a new method for measuring the anatomical parameters of the proximal tibiofibular joint(PTFJ)and to evaluate the correlation between PTFJ anatomical parameters and the occurrence of knee osteoarthritis(OA).Methods Magnetic resonance imaging data from 81 adults were collected and divided into an OA group(40 cases)and a healthy group(41 cases).By com-paring the inclination angle,declination angle,and contact area(including PTFJ contact area S,lateral stress-bearing area S φ,weight-bearing area S τ,and posterior stress-bearing area S ν)of the PTFJ between the two groups,the correlation between PTFJ anatomical parameters and the occurrence of knee osteoarthritis was analyzed.Results The inclination angle,declination angle,and contact areas(S,Sτ,Sν)of the PTFJ in the OA group were significantly greater than those in the healthy group(P<0.05).There was no statistically significant difference between the two groups in the lateral stress-bearing area(Sφ),age,or BMI(P>0.05).Conclusion The anatomical parameters of the proximal tibiofibular joint have a significant impact on the occurrence of knee osteoarthritis;the method of measuring PTFJ anatomical parameters using magnetic resonance imaging demonstrates high accuracy.
