Purpose: This study is to compare the size distribution of current total knee prostheses with a measurements of Korean knees.
Material and Methods : 566 consecutive osteoarthritic knees were measured, intraoperatively, for anteroposterior(AP) dimension of medial and lateral condyle, and mediolateral(ML) dimension of distal femur and proximal tibia. The size distribution of 5 total knee arthroplasty(TKA) systems were compared with these measurements.
Results: Regarding femoral component, the numbers of available lateral AP sizes within +/-1SD of Korean knees were two in Genesis II, PFC-RPF, Scorpio and one in Advance MPK, LPS-Flex. Those of available ML sizes for +/-1SD range were two in all systems. Regarding tibial component, the numbers of available lateral AP sizes for +/-1SD range were four in Scorpio, three in LPS-Flex, PFC-RPF and two in Advance MPK, Genesis II. Those of available ML sizes for +/-1SD range were two in Advance MPK, Scorpio and one in the others.
Conclusion: Korean-friendly total knee prostheses should incorporate the size distribution as well as the dimension of the Korean knees.
