Precontoured locking compression plates (LCPs) are designed for optimum support of the reduced joint surface and have especially been emphasized in reduced bone quality. A lack of evidence still inhibits their broad utilization in elderly patients. Thus, aim of the present study was to investigate the implant-specific radiological outcomes of AO41B3-fractures in young versus elderly patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The hospital\u2019s database was screened for isolated AO41B3-factures, open reduction and internal fixation (ORIF), and radiological follow-up \u226512\u00a0months. CT-scans, radiographs, and patients\u2019 records were analyzed. Patients were attributed as young (18\u201349) or elderly (\u226550\u00a0years). Additional subgrouping was carried out into precontoured LCP and conventional implants. The Rasmussen Radiological Score (RRS) after 12\u00a0months was set as primary outcome parameter. The RRS postoperatively and the medial proximal tibial angle (MPTA) postoperatively and after 12\u00a0months were secondary outcome parameters.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Fifty nine consecutive patients were included (26 young, 38.2 \u00b1 7.8\u00a0years; 33 elderly, 61.3 \u00b1 9.4\u00a0years). There were no significant differences regarding mean size and depression depth of the lateral joint surface fragments. Prior to implant-specific subgrouping, the radiological outcome measures revealed no significant differences between young (RRS = 7.7 \u00b1 1.7; MPTA = 90.3 \u00b1 2.3\u00b0) and elderly (RRS = 7.2 \u00b1 1.7; MPTA = 90.5 \u00b1 3.3\u00b0). After implant-specific subgrouping, the radiological outcome revealed significantly impaired results in young patients with conventional implants (RRS\n                      <jats:sub>(C)<\/jats:sub>\n                      = 6.9 \u00b1 1.6, RRS\n                      <jats:sub>(LCP)<\/jats:sub>\n                      = 8.5 \u00b1 1.5, P = .015; MPTA\n                      <jats:sub>(C)<\/jats:sub>\n                      = 91.5 \u00b1 1.9\u00b0, MPTA\n                      <jats:sub>(LCP)<\/jats:sub>\n                      = 89.1 \u00b1 2.1\u00b0, P = .01).
