Abstract

Background: Knee osteoarthritis (OA) is the most common form of osteoarthritis and a frequent cause of chronic health problems. The femorotibial joint space is one of the most predictive factors associated with clinical symptoms and outcomes in patients with knee OA. Obesity is a major risk factor for the development of knee OA. Measurement of the knee joint space is most accurately performed using the Lyon-Schuss position. Methods: This study is an analytic study with a cross-sectional design. Radiological examinations were performed in the Lyon-Schuss position, and the narrowest femorotibial joint space was measured. Bivariate analysis using the chi-square test The Mann-Whitney U and Kruskal-Wallis test. Correlation analysis was then performed to determine the strength of the relationship between BMI and femorotibial joint space width. Results: Bivariate analysis showed a relationship between BMI and OA grade (p = 0.093), as well as between femorotibial joint space width and both BMI (p = 0.000) and OA grade (p = 0.000). A negative correlation was found between BMI and femorotibial joint space width, with the regression equation: y = 8.577 - 0.255x, where y represents femorotibial joint space width (mm) and x represents BMI (p = 0.000; R² = 0.306). Conclusion: There is a negative correlation between body mass index and femorotibial joint space width in patients with knee osteoarthritis.

Abstract

Introduction: Anterior Cruciate Ligament (ACL) injury is one of the most common knee ligament injuries, particularly in the athletic population. Anatomical risk factors, such as knee bone morphology, are thought to play a crucial role in injury susceptibility. One parameter under investigation is the Lateral Femoral Index (LFCI), which describes the shape of the lateral femoral condyle. This study aimed to analyze the difference in LFCI in patients with ACL rupture compared to normal individuals as a potential risk factor. Methods: This study employed an observational analytic design with a case-control approach, conducted at H. Adam Malik General Hospital, Medan. The sample consisted of 50 subjects divided into two groups: 25 patients with an arthroscopically confirmed diagnosis of ACL rupture (case group) and 25 healthy individuals with no history of knee injury (control group). The LFCI was measured from true lateral projection knee radiographs. An independent T-test was used for statistical analysis to compare the mean LFCI difference between the two groups. Results: The mean age of the study subjects was 30.68 ± 5.35 years. The measurements revealed that the mean LFCI in the ACL rupture group was significantly lower (0.68 ± 0.56) compared to the control group (0.74 ± 0.56). This difference was statistically significant (p < 0.001). Conclusion: There is a significant difference in the Lateral Femoral Index (LFCI) between patients with ACL rupture and normal individuals. A lower LFCI value can be considered an anatomical risk factor for ACL rupture.
