Normal Dimensions of Lateral Femoral Condyle in Pakistani Population

Background: The medial condyle is wider and having larger surface area for articulation than lateral femoral condyle however anteroposteriorly lateral femoral condyle is larger. The aim of this study was to find normal dimensions of lateral femoral condyle in Pakistani population. Methods: This Cross-sectional descriptive study, carried out from September 2023 to May 2024 in Radiology department of Peshawar General Hospital, Peshawar with sample size of 385. Non probability convenience sampling technique was used. All healthy adult, intact femur with clear features were included and scanned through magnetic resonance imaging. Data analysis was done through SPSS version 22, descriptive analysis was done and association was assessed by applying independent sample t-test and ANOVA. P-value ≤ 0.05 considered statistically significant. Results: About 54% (n=149) male participants and 60% (n=67) of females had right knee measurements, whereas 46% (n=125) males and 40% (n=44) females had measurements of their left knee. There was no significant relationship between gender and the measured side (p=0.169). Age and size of the lateral femoral condyle were shown to be significantly correlated (p=0.027). Males exhibited greater femoral condyle dimensions, notch widths, and heights compared to females (p<0.001). Furthermore, ANOVA showed statistically significant variations in parameters of lateral femoral condyle, notch width, and height with age (p<0.001). Conclusions: This study demonstrates that the femoral condyles parameters depend on several variables and differ by gender and region. Considering this study, accurate tunnel in lateral femoral condyle can be made for anterior cruciate ligament graft in ACL injury.
