Abstract: Background: The tibial plateau is the upper most surface of the tibia bone which forms the knee joint together with femoral condyles. It has a medial and lateral condyle. There are increasing cases of osteoarthritis of the knee with increasing age and trauma, hence the need for knee arthroplasty to restore functional anatomy of the knee. Arthroplasty requires accurate sizing of implants to the damaged knee, which will be guided by knowing morphometric measurements of Kenyan tibial plateaus which are unique to those of other populations.
