Details of the Articuleze tapers in which a taper engagement level (TEL) was easily identified versus those in which there was no such finding (and were indistinguishable from a sterile component)
| Characteristics (median and range) | TEL identified (n = 25) | No TEL identified (n = 23) | p-value* | ||
|---|---|---|---|---|---|
| Duration in vivo (mths) | 42 (12 to 74) | 43 (12 to 75) | 0.961 | ||
| Taper angle (°) | 5.639 (5.584 to 5.685) | 5.629 (5.557 to 5.672) | 0.471 | ||
| Diametral clearance (µm) | 88.8 (70.2 to 112.8) | 89.6 (70.2 to 119.4) | 0.855 | ||
| Horizontal lever arm distance (mm) | 17.94 (10.26 to 24.53) | 16.04 (12.34 to 20.89) | 0.007 | ||
| Surface wear (mm3/yr) | 2.03 (0.51 to 6.29) | 3.57 (0.51 to 13.67) | 0.069 | ||
