Brief Summary:

Context: The many treatments and devices developed to unload the diseased articular surface in knee osteoarthritis have provided limited solutions. A novel biomechanical device comprising of four individually calibrated elements attached onto foot-worn platforms was recently developed. This device is capable of such unloading during standing and walking, simultaneously strengthening dynamic stabilizers and training neuromuscular control by controlled biomechanical perturbations.

Objective: To asses the effectiveness of this device in reducing pain and improving function in patients with knee osteoarthritis.

Design and Setting: Randomized, controlled and double blind prospective trial, conducted from September 2005 to February 2006, in the Department of Orthopedics, Asaf Harofeh Medical Center (Zerifin, Israel).

Patients: Sixty-one patients with diagnosed knee osteoarthritis who self-reported moderate-to-severe level pain.

Interventions: Patients were randomly assigned into active and control groups and underwent 8 weeks of treatment. The active group was treated with the device and its four biomechanical elements that had been individually calibrated to accommodate a pain-free joint alignment. The control group was treated with the device's platforms without the biomechanical elements.

Primary Outcome Measures: The patients were evaluated three times during the study: at baseline, after 4 weeks and at the 8 week endpoint. Primary outcomes were the Western Ontario and McMaster Osteoarthritis Index (WOMAC) and the Aggregated Locomotor Function (ALF) assessment.
