Run-in and steady-state gravimetric wear rates (mean ± SE) for the ISO-D, AP-L and AP-H gait protocols. The p values were obtained using a 2-tailed paired t-test comparing the run-in and steady-state wear rates.
| Gait Protocol | Run-in Wear (mg/Mc) | Steady-state Wear (mg/Mc) | Ratio of Steady- state to Run-in | Significance P value |
|---|---|---|---|---|
| ISO | 11.72 ± 6.09 | 10.02 ± 3.71 | 0.86 | 0.573 |
| AP-L | 20.43 ± 6.31 | 14.77 ± 3.02 | 0.82 | 0.457 |
| AP-H | 32.44 ± 5.17 | 18.06 ± 4.62 | 0.56 | 0.025 |
