About

Osteoarthritis is a chronic disease affecting millions of people worldwide, and knee is the second most affected site. Knee osteoarthritis is characterized by knee pain, loss of motion, disability, and muscle weakness, all factors contributing to gait alterations, and impacting greatly the patients quality of life. In the absence of curative treatment, pharmacological and non-pharmacological symptomatic treatments are prescribed to maintain this QoL, and therefore delay surgery to more appropriate window of opportunity later in life.

The aim of the study was to investigate the acute effects of three braces, using different unloading strategies, on gait kinematic and kinetic parameters, as well as pain in patients with medial knee ostoeoarthritis.

13 participants in 4 patient groups

Rebel Reliever
Experimental group
Description:
Rebel Reliever (RR) (Thuasne, Levallois Perret, France) with bilateral rigid frames and two hinges. The valgus correction was set by adjusting the medial and lateral frame lengths to a difference of two or three points as dictated by the participant's feeling and comfort. Six straps maintained the brace in place
Treatment:
Device: Rebel Reliever (RR)
Action Reliever
Experimental group
Description:
Action Reliever (AR) (Thuasne, Levallois Perret, France) made mainly from textile. Upper and lower straps were adjusted to the participant's feeling and comfort.
Treatment:
Device: Action Reliever
Unloader One
Active Comparator group
Description:
Unloader One (UO) (Össur, Reykjavik, Iceland), with unilateral frame and one hinge. Upper and lower straps were adjusted to the setting recommended by the fitting instructions and confirmed by the participant's sensation.
Treatment:
Device: Unloading brace
No orthosis
No Intervention group
Description:
Control condition without brace
