Validating products by clinical research
Össur advocates research-supported validation of the efficiency and functionality of products. Below you can find a number of references to scientific publications in peer-reviewed journals on osteoarthritis of the knee, bracing and the effectiveness of the Unloader One.
Arthritis Research UK
Össur is supporting Arthritis Research UK, a charity leading the fight agains arthritis, and their experimental osteoarthritis center.
There, researchers will evaluate various characteristics of people suffering from osteoarthritis in order to better assess the condition’s mechanisms of action and identify the most appropriate interventions to relieve patients’ pain and restore mobility.
Improvement in Quality of Life with Use of an Unloader Knee Brace in Active Patients with OA: A Prospective Cohort Study.
The Effect of Bracing on Varus Gonarthrosis
Randomized, controlled clinical outcome study comparing the Generation II Unloader knee brace to a neoprene sleeve and to standard medical treatment, (NSAIDs or Acetaminophen, patient education and exercise), (n=119).
Results indicate that patients who have varus gonarthrosis experience a decrease in pain and improvement in disease specific quality of life with the use of an unloader brace, in addition to standard medical treatment. The Unloader brace was more effect than the neoprene sleeve.
Reduction of Medial Compartment Loads with Valgus Bracing of the Osteoarthritic Knee.
Prospective cohort study measuring the load sharing capabilities of the Generation II Unloader knee brace and estimation of its effect on medial compartment force in patients with medial OA, (n=11).
Results indicate that adjustable valgus bracing (Unloader) was effective in reducing medial compartment load and subsequent pain while also improving knee function in patients with osteoarthritis.
Knee bracing for Unicompartmental Osteoarthritis.
A meta-analysis revealed that knee bracing for osteoarthritis may effectively relieve pain and improve function. Braces that reduce excessive loading on the damaged portion of the knee have been proven to be valid brace designs (Unloader brace).
Assessment of Conservative Realignment Therapies for the Treatment of Varus Knee Osteoarthritis.
Gait & Posture, 11(2): 170-171, 2000.
Prospective, randomized clinical outcomes study evaluating the efficacy, biomechanical gait analysis and changes to joint pathophysiology using the Generation II Unloader knee brace with and without in-shoe foot orthoses for the treatment of varus knee osteoarthritis (n=15).
Results indicate that valgus knee bracing, (Unloader), and neutral position foot orthoses, significantly improve lower extremity biomechanics during gait, ADLs and pain assessments in varus knee OA patients.
Valgus Knee Bracing for Medial Gonarthrosis.
Randomized double cross-over study evaluating pain and function in patients with medial compartment gonarthrosis (n=39).
Results indicate that valgus bracing, using the Generation II Unloader, can be a useful treatment modality for reducing pain in patients with medial gonarthrosis.
