In addition, they can enhance Zone 2 fixation in R\u2010TKA in the presence of poor bone quality. The aim of this study was to evaluate the short\u2010term clinical and radiological outcomes of a novel three\u2010dimensional (3D)\u2010printed metaphyseal cone in R\u2010TKA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This single\u2010centre, single\u2010surgeon prospective study included all patients who underwent R\u2010TKA using a novel 3D\u2010printed anatomical metaphyseal cone (AMF, ENOVIS\u00ae) with a minimum follow\u2010up of 24 months. Patient demographics and operative details were recorded. Postoperative assessments included the Knee Society Score (KSS), Oxford Knee Score (OKS) and Short Form\u201012 (SF\u201012). Radiographic evaluation focused on radiolucent lines, implant or cone loosening and the cone's ability to replicate proximal tibial anatomy. Complications, reoperations and revisions for any reason were documented.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Thirty patients (31 knees) underwent R\u2010TKA with a total of 48 cones (24 tibial and 24 femoral), with a mean follow\u2010up of 37.3 months (standard deviation [SD] 8.8). In 48.4% of cases, cones were used on both the tibial and femoral sides. No intraoperative fractures occurred during cone preparation. All patients demonstrated significant improvement in clinical outcomes. Radiographic evaluation showed no evidence of cone loosening and accurate reproduction of proximal tibial anatomy. Survivorship free from cone revision, including for aseptic loosening, was 100%. Survivorship free from any revision or reoperation was also 100%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This novel 3D\u2010printed anatomical metaphyseal cone demonstrated excellent short\u2010term outcomes, with no early loosening and accurate replication of proximal tibial morphology.
