Intraoperative Navigation, 3D Printed Prostheses, and Conventional Techniques in Femoral and Tibial Tumor Resections: A Systematic Review.

A systematic search of PubMed, Embase, and Cochrane Library databases (2014-2024) identified studies on lower extremity bone tumor resections involving 3D prostheses/patient-specific instruments (3D patient-specific instrumentation), intraoperative navigation, and control conventional surgeries.

Weighted mean infection rates were 3.3 ± 6.2% for 3D patient-specific instrumentation, 3.4 ± 4.3% for intraoperative navigation, and 7.2 ± 7.8% for conventional.

Mean revision rates were 1.6 ± 5.4% for 3D patient-specific instrumentation, 2.5 ± 5.6% for intraoperative navigation, and 7.2 ± 3.1% for conventional.
