Key result
Total hip replacements using the Charnley technique demonstrated a 2.2% rate of mechanical failure at the cement-bone interface over an average follow-up of 8.3 years.

What is the long-term rate of mechanical failure and bone-cement interface pathology following Charnley total hip replacement?
Long-term follow-up of Charnley total hip replacements demonstrates a low rate of mechanical failure at the cement-bone interface, suggesting that cement failure is largely preventable with improved technology.
Griffith et al. (1978) conducted an observational in Total hip replacement (n=547). Charnley technique for total hip replacement was evaluated on Mechanical failure at the cement-bone interface. Total hip replacements using the Charnley technique demonstrated a 2.2% rate of mechanical failure at the cement-bone interface over an average follow-up of 8.3 years.
