Effects of a New Knee Brace for Treatment of the Knee Osteoarthritis

The purpose of this study is to evaluate the immediate effects of a knee brace with a new mechanism on the pain and medial knee loading during gait among medial knee osteoarthritis patients. The effects of this new brace is compared to a stabilizing brace and a typical valgus knee brace. The investigators recruited 24 knee osteoarthritis and they have to wear each of the three braces during three months. A fifteen days wash-out period is given after each three months. Biomechanical evaluation is carried out before and after each three months. This evaluation consisted of three questionnaires (KOOS, WOMAC and Medical Outcome Score Short Form-36 (MOS-SF36)), a motion analysis with an optoelectronic system, then a 6-min walk test. During motion analysis, ten gait trials are executed without brace and ten with the brace.

Treatment and study plan

Stabilizing Knee Brace

Device

Brace with no valgus action

Valgus Knee Brace

Device

Valgus brace with traditional three point bending system

New Knee Brace

Device

Brace with new mechanism to decrease the knee loading.

Primary outcomes

  1. Change in Knee adduction moment

    Time frame: Change from Baseline at 3 months

  2. Change in Knee pain

    Time frame: Change from Baseline at 3 months

    A 20-cm visual analog scale (0-100) is used to assess pain.

Secondary outcomes

  1. Change in Spatiotemporal gait parameters

    Time frame: Change from Baseline at 3 months

    Test of the gait symmetry with the gait phase duration and step length.

  2. Change in Gait velocity

    Time frame: Change from Baseline at 3 months

  3. Change in Knee adduction angle

    Time frame: Change from Baseline at 3 months

  4. Change in Knee brace comfort

    Time frame: Change from Baseline at 3 months

    A 20-cm visual analog scale (0-100) is used to assess comfort.
