Data relating to Table 1: surface roughness of tibial and femoral components pre- and post-test for MRK and SAIPH.  For the femoral components, the value is the average of 10 traces (5 per condyle) through fle flexion range; for the tibial components, the value is the average of 8 traces (4 per compartment)
