Dr. Lynn Snyder-Mackler recently published a trial that addressed the question:  Do lateral wedge insoles or flat control insoles improve symptoms and slow structural disease progression in medial knee osteoarthritis?

The study concluded that lateral wedge insoles worn for 12 months provided no symptomatic or structural benefits compared with flat control insoles.

The double blind randomized control trial looked at 200 patients with qualified knee pain from osteoarthritis.  Participants wore insoles in both of their shoes everyday for 12 months.  Every four months they switched between the lateral wedge insole and the flat insole.

The results after 12 months is that lateral wedge insoles worn for one year provided no symptomatic or structural benefits compared with flat control insoles.
