Asterisk Ultra Cell Knee Brace - White

Also available in Black

The UltraCell™ is built on 10+ years of time-tested and proven designs of the original Cell® Knee Protection System. Those original concepts have been refined, improved, and entirely re-engineered to create the UltraCell™. The UltraCell™ is, as its predecessor, completely customizable to the leg while remaining extremely rigid.

Asymmetry Glide Hinge

  • Allows for automatic tibia alignment of lower frame
  • Condyle shims for fine tuning fit

A.R.C. Cuff

  • Adjustable retention control
  • Multiform rigid lateral support
  • Built in anti rotation connection
  • Stainless steel retention strips 
  • Inverted adjustment increases lateral rigidity

Anti-Rotation Tether

  • Links the brace to the boot making them as one

  • Adjustable to suit each individual

Dual Independent Securement system

  • Medial macro-adjustment
  • Superior security to strapping
  • Boa® closure system provides smooth even closure and no pressure points
  • Quick Release tabs

Tele-tri Patella cup

  • Telescoping three piece design
  • High impact nylon 6 material
  • Full range of motion coverage of the knee cap
  • Thermo-formed EV50 Shock absorbent foam padding

Thermo-formed padding

To ensure proper fit, circumference measurements should be taken directly on the skin with the leg straightened, using a soft tape measure. (If soft tape measure is not available, a piece of string or yarn may be used to calibrate the leg's diameter.) Locate the middle of the kneecap and measure around the leg. Measurements should be taken directly on the skin with a straight leg.
