Despite these advantages, the ability of short-stem implants to reliably restore leg length and offset remains debated.

Femoral offset and leg length were measured, and the accuracy of anatomical reconstruction was assessed within a 5-mm target range. Comparisons were made between a single offset (130\u00b0) implant and a dual-offset system (130\u00b0 and 119\u00b0) using the McNemar-Bowker test.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      With a single 130\u00b0 CCD (Caput-collum-diaphyseal) offset implant, 55.7% (82\/148) of cases achieved satisfactory leg length and offset restoration. The use of a dual-offset system improved accuracy to 79.1% (117\/148), demonstrating a statistically significant advantage (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>The study highlights the need for at least two CCD-angle-offset combinations in short-stem THA to address anatomical variability.
