The Rx Knee 1.5 Spacer is a purpose-designed solution for staged revision of infected total knee replacements, offering a reliable bridge between explantation and reimplantation. Featuring a robust femoral-tibial articulation with increased stability and strength over traditional articulating spacers, the Rx Knee’s geometry reflects clinically proven design principles while accommodating a wide range of bone loss scenarios. The system is supplied sterile with modular femoral and tibial components, allowing intraoperative flexibility for limb length and alignment restoration.

Designed with surgeon workflow and patient recovery in mind, the Rx Knee 1.5 Spacer provides temporary joint function during infection eradication, enabling mobility while protecting soft tissue tension and joint space. The articulating design facilitates improved range of motion during the interim phase, and the system supports both cemented and cementless techniques. Manufactured from high-strength materials compatible with antibiotic-loaded cement, the Rx Knee offers a dependable, versatile option in complex revision cases.
