Abstract

Patellofemoral osteoarthritis (PFOA) is a common disease that causes pain, reduced motor function, and disability. Abnormal Insall-Salvati index has been proven to be associated with PFOA. Therefore, this study aims to assess the correlation between patellar position and the degree of PFOA in patients with primary PFOA at the Thai Nguyen University of Medicine and Pharmacy Hospital. Subjects and methods: A cross-sectional descriptive study was conducted on 50 knee joints of 32 patients with primary knee osteoarthritis according to the 1991 ACR criteria. Patients underwent weight-bearing anterior-posterior and lateral knee X-rays, and the degree of osteoarthritis was evaluated using the Kellgren and Lawrence scale. Data were analyzed and processed using SPSS 25.0 software. Results: The average Insall-Salvati index in the study group was 1.27±0.22. The degree of osteoarthritis showed a moderate positive correlation with occupation (r=0.41, p<0.05) and a high positive correlation with the Insall-Salvati index (r=0.75, P< 0.001).
