Shoe inserts are no benefit to knee pain: New Study
,br> Foot orthoses i.e. shoe inserts (or insoles) are designed to shift body weight from the inside of the knee to the outside in the hopes of reducing pain are ineffective according to recent research published in the Journal of the American Medical Association. The meta analysis review was conducted at the University of Manchester. Twelve (12) papers using patient-reported pain as an outcome and describing randomized trials comparing shoe-based treatments (lateral heel wedge insoles or shoes with variable stiffness soles) aimed at reducing medial knee load, with a neutral or no wedge control condition in patients with painful medial knee osteoarthritis were analised. The studies included a total of 885 patients with osteoarthritis of the knee. Statistical analysies supported lateral wedged shoe inserts do not significantly relieve pain in patients suffering from osteoarthritis of the knee. Researchers found there was a small positive effect from the inserts in the smaller studies but bigger trials and those that compared the wedge inserts with non-angled inserts, there was no significant benefit from the wedge inserts. Researchers were left to conclude shoe inserts had no benefit to knee pain.
A background to foot orthoses which is passed on in good faith.
