Total hip replacement is a common and highly effective operation. All hip replacements eventually fail if in-situ long enough and it is important that patients understand when this might happen. This meta-analysis published in the Lancet
, included 44 case series that reported long-term outcomes of 13,212 hip replacement procedures. The authors also carried out a meta-analysis of data taken from national joint replacement registries in Australia and Finland. These provided 215,676 procedures, with outcomes at 15, 20 and 25 years. After 15 years, 89.4% of hip replacements had survived (data from Australian and Finnish registries). After 25 years, 57.9% were still intact (but data only available from the Finnish registry).
