Medial arch supports do not significantly alter the knee adduction moment in people with knee osteoarthritis

Abstract

This study showed no mean change in any of the measured indices of medial knee load with medial arch supports. No immediate changes in knee pain were evident.

The effects of shoe-worn insoles on gait biomechanics in people with knee osteoarthritis: a systematic review and meta-analysis

“…However, Hinman et al 17 found no statistically significant changes with medial arch supports in any aspect of the KAM or external hip adduction moment, while Turpin et al 18 found no changes with shock absorbing insoles in any aspect of the KAM.…”

“…Only one study each was identified that examined the use of medial arch supports17 or shock absorbing insoles,18 and therefore data pooling was not possible. However, Hinman et al 17 found no statistically significant changes with medial arch supports in any aspect of the KAM or external hip adduction moment, while Turpin et al 18 found no changes with shock absorbing insoles in any aspect of the KAM.…”

A systematic review and meta-analysis into the effect of lateral wedge arch support insoles for reducing knee joint load in patients with medial knee osteoarthritis

“…The hypothesis above needs to be further studied, emphasizing the importance of coordination between the lateral wedge and medial arch. It is worth mentioning that we have not analyzed the participants’ different responses and individual variations, which could be conspicuous as Hinman et al [38] observed. In addition, there are only 2 comparisons included in the neutral insole group for the second EKAM.…”

“…[47,59] The reported effects of the neutral insole are not consistent in recent studies. [38,65] Although meta-analysis pooling of all studies showed statistically significant associations between the use of LWAS and reductions of the first peak EKAM, second peak EKAM and KAAI during walking for people with medial knee OA, different results were observed when comparing with various control conditions. With regard to the first peak EKAM, the use of LWAS results in a small but statistically significant reduction when the control group is the neutral insole, whereas no significant difference existed in the shoe-only or flat insole condition.…”

A survey of footwear advice, beliefs and wear habits in people with knee osteoarthritis

“…Similarly, the addition of medial arch supports into shoes has been associated with increased knee loads [25,26], suggesting that increasing foot supination and/or restricting foot pronation may have adverse effects on loading at the knee joint. In this context, it is of interest to note that the third, fourth and sixth styles most commonly advised to be bad for knee OA symptoms by health professionals were flexible thin soled shoes, barefoot and flat shoes, respectively.…”
