SKII PS High Flexion Total Knee System

High Flexion Total Knee System

Product Overview

  • Intraoperative Flexibility
    The choice between PS or PS+ tibial bearing to optimize stability:

PS: No varus/valgus constraint, allows up to 15° internal/external rotation.

PS+: Restricts 2° varus/valgus deviation and ±2° internal/external rotation.

  • Enhanced Stability
    An anterior dovetail design on the tibial bearing minimizes micromotion between the bearing and tibial tray compared to competing brands.
  • Osteolysis Risk Reduction
    A tapped bind hole on the tibial tray effectively reduces the risk of osteolysis caused by wear.

Special Description

2 Options of Tibial Bearings

Standard and PLUS

PS: No varus/valgus constraint

PS: 15 degrees internal/external rotation

PS+: 2 degrees varus/valgus constraint

PS+: +/-2 degrees internal/external rotation

Using in a primary situation when more stability and initial constraint is desired to resist rotation and varus/valgus lift-off

Stem Extensions

For optimal stress distribution

Same Platform Design

Meets requirements of both primary and complex primary TKA

Augment Options

Multiple specifications tibial augment for varying degrees or shapes of the tibial bone defect

Product Features-Seamless System，Deal with Possible Bone Defects

Normal Primary TKA

Complex Primary TKA

Tibial defect is treated with tibial augment stem is required to protect the defect.

Large central tibial defect is treatedwith tibial cone stem is used to strengthen prosthesis fixation.
