Abstract
-
PURPOSE: This study is to compare the size distribution of current total knee prostheses with a measurements of Korean knees.
MATERIALS 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.
