All patients had unicondylar defects involving the articular surface. Twelve patients were treated with a 3D-printed custom-made prosthesis to repair the unicondylar defect (3D-printed group). The other 14 patients were treated with total knee replacement (TKR group). The operation time, blood loss, Musculoskeletal Tumor Society score, range of motion, local recurrence, and complications were statistically compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The operation time was significantly shorter and the blood loss was significantly less in the 3D-printed group than in the TKR group.

The range of motion was significantly better in the 3D-printed group than in the TKR group at 6 and 9 months postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
