The JXXD Knee Joint System is engineered for precise, reliable total knee replacement, featuring CR (cruciate-retaining) and PS (posterior-stabilized) femoral components tailored to Chinese anatomical traits. With a rich size array (AP: 52-72mm, 2mm increments) and half-size options, it ensures optimal fit.

Femoral designs prioritize bone preservation—optimized intercondylar fossa, reduced posterior condyle resection—and minimize wear via curved Post-Cam and 冠状 articular surfaces. They support safe high flexion with extended tibial tracking and increased jump distance to prevent dislocation.

Tibial components include 5° posterior-tilted liners (1mm incremental thicknesses) for anatomical alignment and flexible gap balancing, plus modular tibial trays (cementless/cementable, CMA/MB types). The CMA tray features enhanced cement grooves for strong fixation, while the MB tray allows add-on spacers/extension rods for tibial defects. A full-enclosure locking mechanism reduces liner backside wear, ensuring durability. Ideal for primary and complex cases, the system blends adaptability with clinical safety.
