Abstract

Total Knee Arthroplasty abbreviated TKA has been widely used as a way to treat knee joint disorders. The development of a single radius system at TKA is expected to meet the needs of Asians, especially Indonesians. It^s used to support religious, social and cultural activities. This study aims to determine the effect of the femoral condyle radius on the range of flexion angles, as well as the TKA stability on the gap difference abbreviated GD. This study uses references from previous study. Variations in the femoral condyle radius that are applied are 21.5 mm, 22 mm, 22.5 mm become reference model, 23 mm, and 23.5 mm. The most optimal TKA design is 23.5 mm on femoral condyle radius. This variant capable of chieving a flexion angle of 164.5 degrees, and stability of GD based shows 1.3 mm. The results of this study indicate a better design, and are expected to provide comfort for patients.
