Livermore et al. developed a standardized radiographic technique to measure polyethylene wear in THA and applied it to 385 hips followed at least 9.5 years. The study directly compared linear and volumetric wear across 22mm, 28mm, and 32mm femoral heads in comparable patient populations. This was the first long-term clinical study to quantify how head diameter determines both the pattern and magnitude of acetabular polyethylene wear.
