31 μm (interquartile range (IQR) 77.59 to 97.4; 32% (n = 26) were found to have been below the manufacturing tolerance. There was no correlation found between clearance and bearing (r = -0.0004, p = 0.997) or taper (r = 0.0048, p = 0.966) wear rates. The wear performance of hips manufactured within and below these specifications was not significantly different (bearing p = 0.395; taper p = 0.653). Pinnacles manufactured from 2007 onwards had a greater prevalence of bearing clearance below tolerance (p = 0.004). The diametrical clear
