INTRODUCTION: In Sri Lankan context there are no published data for articulator surface measurements for knee joints. Forensic, Anatomical, Archaeological, Bio-medical engineering, development of knee S145 prosthesis beneficial with anthropometrics. Digital Vernier Caliper (measuring range 0-140mm, resolution 0.02mm, accuracy ±0.01mm) used to obtain measurements.
OBJECTIVES: The aim of this study, was to provide standard anthropometrics for the distal femur in Sri Lankan context. METHODS: Dried adult Femurs (42 male and 28 female) were analysed for the measurements of Medial condyle Antero-Postero Length (MAP), Anteroposterior length of intercondylar area (AP), Medial-Lateral Length (ML), Aspect Ratio (ML/AP) and Epi Condylar breadth (EB). Sex Dimorphism Ratio (SDR) were calculated for dry femurs. RESULTS: The mean values for male; MAP 24.95(±2.22), AP 25.47(±2.27), ML 20.82(±2.56), Aspect Ratio 0.82(±0.11) and EB 7.68(±0.43). The mean values for female; MAP 24.95(±3.08), AP 25.47(±3.16), ML 20.82(±2.28), Aspect Ratio 0.82(±0.18) and EB 7.68(±0.37). SDR values are MAP 107.74, AP 107.12, ML 99.04, and EB 106.55. CONCLUSIONS: The majority of SDR values lie above 100. Therefore, a difference between male and female values can be observed. Findings offer assistance to develop knee joint prostheses with culture-particular values, fitting for the Sri Lankan setting and pave the pathway to the studies on the above-mentioned fields in the local and international context. Sex determination is a crucial element in the creation of a biological profile since it offers information for identities. |
