SKII PS & SKII PLUS

– Designed for high-flexion activity

– Optimized patellofemoral joint surface design to enhance postoperative mobility

– Customized prosthesis models to meet the diverse needs of different body types and patients

– Proportionally increased posterior condyle on the lateral side, expanding the joint contact area for improved force transmission and reduced wear

– Ultra-mirror polishing treatment to minimize wear during postoperative femoral condyle movement and effectively reduce debris generation

– Smooth intercondylar groove treatment, ensuring an equal amount of intercondylar groove resection to reduce wear and collisions in flexion activities

– Extended cam, effectively avoiding the risk of postoperative dislocation in the tibiofemoral joint.

  • Tibial Bearing

SKII PS

  • Designed for high-flexion activity
  • Allows rotation and flexion-extension movement of the knee joint
  • Compatible with all models of femoral condyle prostheses
  • 1:1 contact ratio between tibial and femoral joint surfaces, increasing joint contact area and effectively reducing wear during postoperative movement
  • Circular post design reduces stress and prevents dislocation of the tibiofemoral joint
  • The patellar groove design protects the patellar tendon in high-flexion positions
  • The back side of the tibial tray insert is easily navigated, enabling accurate and fast installation of the tray insert on the tibial platform during surgery.
  • Tibial Bearing

SKII PLUS

  • Widened semi-constrained pillar design, effectively addressing knee joint instability;
  • Design with high flexion range of motion;
  • Allowing for a ±2° varus/valgus constraint and ±2° internal/external rotation;
  • Compatibility with all models of femoral condyle implants;
  • 1:1 contact between the tibia and femoral joint surface, increasing joint contact area while effectively preventing wear during postoperative movement;
  • Patellar groove design to protect the patellar tendon in high flexion positions;
  • Ease of posterior insertion of the tibial platform, achieving accurate and rapid installation of the platform and tibial plateau during surgery.
  • Flexible switching between PS and PS+ during surgery based on the patient’s medial and lateral collateral ligament conditions.
  • Tibial Platform

SKII PS & SKII PLUS

  • Reduced side wings, effectively minimizing intraoperative bone loss;
  • The combination of dovetail groove and anterior locking mechanism optimizes the locking mechanism while reducing posterior micromotion;
  • A hollow cylindrical tibial base accommodates the smooth transition from routine primary replacement to complex primary replacement with extension stems during surgery;
  • The posterior aspect of the tibial platform can connect with a tibial insert to address clinical issues related to tibial side bone defects;
  • The mirror-polished surface treatment effectively reduces wear on the posterior side of the platform, minimizing debris generation.
