Abstract :Aim: To evaluate the relationship between severity of subchondral insufficiency fracture of the knee insert ignore into journalissuearticles values(SIFK); and age, gender, knee alingment, meniscus tear, type and location, severity of meniscus extrusion, and degree of knee osteoarthritis. Material and Method: This retrospective study included 308 patients with SIFK seen on MRI. SIFK lesions were categorized as grade 1 to 4, with distinction between low grade insert ignore into journalissuearticles values(1 and 2); and high grade insert ignore into journalissuearticles values(3 and 4);. The relationships between SIFK grade and patients` age, body mass index insert ignore into journalissuearticles values(BMI);, femorotibial angle insert ignore into journalissuearticles values(FTA);, meniscus tear,type and location meniscusextrusiongrade and osteoarthritis insert ignore into journalissuearticles values(grade 0 to grade 4); evaluated. Results: According to the gender, 39.3% were men and 60.7% were women. The distrubutin of the SIFK grades were respectively 42.2% grade 1, 30.8% grade 2, 22.7% grade 3 and 4.2% grade 4. FTAwas positively correlated with SIFK grade insert ignore into journalissuearticles values(from grade 1 to grade 4, respectively; 4.42±2.57, 5.09±2.26, 5.74±2.78 and 5.95±2.54); insert ignore into journalissuearticles values(p=0.002);. No statistically significant difference was observed between height, weight and BMI and the degree of SIFK.The mean FTA was 4.99±2.57° in SIFK. The FTA angles showed a stastistically significance between low insert ignore into journalissuearticles values(4.73±2.48°); and high insert ignore into journalissuearticles values(5.71±2.69°);grade SIFK insert ignore into journalissuearticles values(p:0.003);. Roc analysis showed that the FTA above 3.1° and the age above 52 year old were at risk. The mean extent of meniscal extrusion was larger in high grade SIFK insert ignore into journalissuearticles values(p=0.001);. Multivariable logistic regression analysis showed that compared with low grade SIFK, high grade SIFK was more closely associated with age, FTA, lateral meniscus extrusion and medial meniscus tear type. Conclusion: High-grade SIFK lesions are associated with higher FTA and older age. In particular, patients with acute knee pain, older than 52 years of ageanda higher FTA than 3.1°, we recommend to perform knee MRI if possible.
