BACKGROUNDInjury of knee is very common in athletes and Anterior Cruciate Ligament (ACL) is the most ruptured ligament.It has been proposed that a narrow intercondylar notch increases risk of ACL injury, but the data are conflicting.This study aimed to analyse morphometry of femoral condyles and intercondylar notch as the literature is sparse in North Indian population and its clinical implications. MATERIALS AND METHODSThe present investigation was conducted using 100 dry femora.The dimensions studied were condylar width and depth, intercondylar notch width and depth.The shape of notch was also examined.The results were tabulated. RESULTSThe shape of intercondylar notch was inverted U shape in 75 (75%) cases and inverted V shape in 25 (25%) cases.The mean condylar width and depth, intercondylar notch width and intercondylar notch depth 64 ± 6.34, 58.16 ± 4.54, 21.12 ± 2.83 and 26.8 ± 2.88 mm respectively.The notch width index and notch depth index were determined as 0.29 and 0.46 respectively.Statistical Analysis-The morphometric data of the present study was represented as mean ± SD and then analysed by unpaired 't' test by using SPSS software (version 19).Measurements were compared statistically with respect to left and right sides and were tabulated. CONCLUSIONMorphometric data contributed by this study will assist orthopaedicians in averting ACL injuries and administer appropriate treatment in knee problems.
