While THA is the gold standard for hip replacement, RHA is increasingly used in younger, active patients due to bone preservation. This systematic review and meta\u2010analysis compare functional outcomes, metal ions, complications, revision rates, survivorship and satisfaction between THA and RHA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic search of EMBASE, Cochrane Library and PubMed was conducted (inception\u2013August 2024) to identify primary research articles for THA and RHA. Risk of bias was assessed using the Newcastle\u2013Ottawa Quality Assessment Scale. A meta\u2010analysis using MATLAB applied a random\u2010effects model to calculate pooled effect sizes for functional scores, revision rates, complications and metal ions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Initial search collated 2265 studies, of which 11 met inclusion criteria (2013\u20132021). Most frequently reported outcomes included complications, revision rates and UCLA. RHA showed better UCLA, HHS and chromium levels, while THA had better WOMAC and cobalt levels, although differences were nonsignificant. Total complications were higher with THA, though nonsignificant. The most common complications were aseptic loosening and dislocation for RHA and THA, respectively. Notably, when the dislocation rate was analysed in isolation, a statistically significant higher dislocation rate was demonstrated with THA. Revision rates were higher for THA, and survivorship was 85.5% compared to 89.5% (RHA), however, with no statistical difference. Statistically significant higher preference for RHA (66.1%) was reported in one study. Satisfaction was greater for RHA (87.8% vs 83.9%) and more patients perceived their hip as natural. One study reported significantly higher quality of life with THA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Patient\u2010reported outcomes, metal ions, complications, revision rates and survivorship were broadly similar between RHA and THA.
