Donjoy have launched a new version of their extremely popular anterior knee pain brace which is specifically for people suffering from Osteoarthritis.

The new brace is able to offload either the medial or lateral knee compartments, or the patellofemoral joint, dependent on your individual requirements. This brace has been scientifically proven (see the recently published research article below) to help people with knee pain and the new additions for Osteoarthritis of the knee are ground breaking.

If you are interested in ordering one or to find out more, please contact us.

The effect of the Reaction Brace on Knee stability during clinical assessment tasks

Study Report
Richards J, Selfe J, Chohan A, Janssen J
Allied Health Research unit, University of Central Lancashire, Preston, UK


knee brace Design: Biomechanical study.
Subjects: 10 healthy volunteers + 2 patients with self-reported knee instability.
: subjects performed functional tasks with and without Reaction brace
- Step-down from 20cm step
- Drop jump from a 20cm step landing on one leg
- Single limb hopping
- Lunge

: To assess the dynamic control of the knee.

Figure 1: Transverse plane knee angle ROM (degrees) during drop-jump in 10 healthy subjects.
The Reaction brace (grey) significantly reduced rotation of the tibia relative to the femur with 21% indicating increased torsional control compared to no brace (blue).
  Figure 2: Range of Motion (cm) in the Medial-lateral Knee Position (relative to the foot) during Drop Jump in 10 healthy subjects.
Reaction brace (grey) reduced medial-lateral movement of the knee with 29% indicating increased ability to control the position of the knee over the foot.


Improved knee control in subjects with unstable knees

Figure 3: Knee ROM during hopping in a subject with knee instability.
The Reaction brace produced a more neutral and stable knee position in all planes (black line is more straight) . Reduced varus/valgus ROM (coronal plane) and reduced torsional ROM (transverse plane) indicate improved knee control during the single leg hopping task and are clinically relevant.



The Reaction Brace offers clinically important changes to knee control and stability in healthy individuals with no reported knee instability and those with reported knee instability.
