BACKGROUND: We aim to measure the proximal tibia and distal femur of the osteoarthritic knees of Arab patients and to compare these measurements with data on other ethnic groups available in literature and with the dimensions of 6 knee implants.
METHODS: Anteroposterior and mediolateral measurements of tibia and femur were done on 3-dimensional computed tomography reconstructions of 124 osteoarthritic knees undergoing total knee arthroplasty with patient-specific instruments.
RESULTS: Average mediolateral and anteroposterior dimensions of the tibia for Arab knees were 74.36 ± 6 mm and 48.94 ± 4.57 mm, respectively, whereas for femur, 72.04 ± 6.6 and 68.1 ± 7.75, respectively. Average aspect ratio for tibial was 152.62 ± 12.66 and for femur 106.37 ± 14.34.
CONCLUSION: The size of Arab knees was generally smaller than Caucasian and larger than Asian. There is significant asymmetry of proximal tibial plateau and femur condyles.
