in 12% of the primary reconstructions (HR 1.87). Uncemented HA-coated distal femoral replacements had a ve-fold lower risk of loosening than uncemented uncoated distal femoral replacements (HR 0.21). Structural complications occurred in 15 reconstructions (14%), infections in 14 (13%). With failure for mechanical reasons as the endpoint, the cumulative incidences of implant failure at 5, 10, and 15 years were 16.9%, 20.7%, and 37.9%, respectively. We concluded that MUTARS modular endoprostheses represent a reliable long-term option for knee replacement after tumor resection, and recommended the use of uncemented hydroxyapatite-coated implants.
