چکیده

This study presents a pilot investigation into the effectiveness of unloader knee braces for osteoarthritis subjects. The unloading effect of the brace was modeled by applying a knee abduction moment as a function of the brace deflection angle, eliminating the need for load sensors on the knee brace. The use of a detailed musculoskeletal model provided the means to evaluate the relative importance of external moments and individual muscle contributions to changes in the joint contact force. Preliminary results from our pilot study suggest that the majority of the medial contact load reduction due to brace use was a result of changes in ground reaction and muscle forces, not of the actual unloader moment applied by the brace.

Unloading knee brace is a cost-effective method to bridge and delay surgery in unicompartmental knee arthritis

BACKGROUND Unloading knee braces can provide good short-term pain relief for some patients with unicompartmental osteoarthritis (UOA). Their cost is relatively small compared with surgical interventions. However, no previous studies have reported their use over a duration of 5 years or more. METHODS Up to 8 years of prospective data were collected from 63 patients who presented with UOA. Afte...

Long-term results of an unloader brace in patients with unicompartmental knee osteoarthritis.

Previously, we reported a prospective study of 30 patients with unicompartmental osteoarthritis of the knee treated nonoperatively with an unloader brace and average follow-up of 2.7 years. Although the initial study suggested short-term benefit according to pain and function measures, the objective of the current study was to evaluate these same patients via telephone questionnaire to determin...

Immediate Effects of a Brace on Gait Biomechanics for Predominant Lateral Knee Osteoarthritis and Valgus Malalignment After Anterior Cruciate Ligament Reconstruction.

BACKGROUND Lateral knee osteoarthritis is notably common after anterior cruciate ligament reconstruction (ACLR). While valgus bracing has been investigated as an intervention for medial knee osteoarthritis (OA), little is known about the effectiveness of varus bracing for lateral knee OA after ACLR. PURPOSE To determine the immediate effects of a varus unloader knee brace on gait biomechanics...
