Background: Arthritis and injuries of the knee are frequently managed by knee arthroplasty. Knee prosthesis thus used needs population specific appropriate sizing. The aim of the study is to analyse tibial plateau morphometrically.

Methods: The study included 46 human tibia bones (28 left and 18 right). The anteroposterior length and transverse width of superior articular surface of both tibial condyles along with the anteroposterior length and transverse measurements of the intercondylar area were noted with digital Vernier caliper. The data was tabulated and analysed.

Results: For the superior articular surface of medial condyle, anteroposterior length was found to be 4.12±0.42cm on left side and 4.17±0.50cm on right side; maximum width was found to be 2.81±0.59cm on left side and 2.78±0.34cm on right side. For the superior surface of lateral condyle, the anteroposterior length was found to be 3.92±0.30cm on left side and 3.66±0.31cm on right side whereas maximum width was found to be 3.12±0.68cm on left side and 2.87±0.55cm on right side. Anteroposterior length of intercondylar area was measured to be 4.31±0.40cm on left side and 4.18±0.44cm on right side. The transverse measurement was recorded to be 3.12±0.68cm (left side), 2.87±0.55cm (right side) anteriorly; 1.25±0.23cm (left side), 1.31±0.20cm (right side) in the middle and 1.28±0.39cm (left side), 1.85±0.42cm (right side) posteriorly.

Conclusions: The results will be helpful in orthopaedic surgical procedures involving knee.
