Evaluating the Efficacy of Lateral Heel Wedges of Osteoarthritis of the Knee

Stopped early · Not applicable

Conditions studied: Knee Osteoarthritis

In brief

This study is looking at the efficacy of a sloped insole in patients with knee osteoarthritis. Regularly wearing a sloped insole over the course of one year will result in a wider joint space by x-ray in 60% of the subjects, a significant decrease in knee pain, decreased use of over the counter analgesics, and a clinically important improvement in the Womac pain and stiffness scale.
