Medial arch supports do not significantly alter the knee adduction moment in people with knee osteoarthritis.
Hinman RS, Bardin L, Simic M, Bennell KL.
Osteoarthritis Cartilage. 2013 Jan;21(1):28-34.

OBJECTIVE:
This study aimed to evaluate the immediate effects of medial arch supports on indices of medial knee joint load (the peak external knee adduction moment (KAM) and knee adduction angular (KAA) impulse) and knee pain during walking in people with medial knee osteoarthritis (OA).
DESIGN:
Twenty-one people with medial compartment OA underwent gait analysis in standardised athletic shoes wearing (1) no medial arch supports and (2) prefabricated medial arch supports, in random order. Outcomes were the first and second peaks in the external KAM, the KAA impulse and severity of knee pain during testing. Outcomes were compared across conditions using paired t tests (gait data) and Wilcoxon Signed Ranks test (pain data).
RESULTS:
There were no significant changes in either first or second peak KAM, or in the KAA impulse, with the addition of medial arch supports (all P > 0.05). Considerable individual variation in response to the arch supports was observed across participants. There was no immediate change in knee pain during walking when medial arch supports were worn (P = 0.56).
CONCLUSIONS:
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.

My observation is that the arch adapts to try to relieve the stress on the knee arthrose coming from posture distortion causing a noxious angle through the knee. Therefore posture correction first leaving the arch if healthy free to do its job is the best approach.

Effects of Arch Support Insoles on Gait Patterns of Patients with Knee Osteoarthritis
Shu-Zon Lou, Fong-Chin Su, Yu-Chi Chen
Journal of Medical and Biological Engineering' March 2015

Although arch support orthotics are prescribed for knee osteoarthritis (OA) patients in clinics, the biomechanical effects of such devices are not fully clear. This study conducts an experimental investigation to evaluate the short-term effects of shoes with arch support insoles on the gait patterns of patients with knee OA during level walking. Twelve adults with knee OA were recruited, and biomechanical data were measured under three test conditions: walking barefoot, walking in shoes, and walking in shoes and insoles. Participants’ gait patterns were recorded and analyzed using a motion analysis system, Kistler force plates, and EVaRT software. Walking in shoes with insoles significantly increased the peak knee flexion angle and the peak dorsiflexion and external rotation angles of the ankle, but reduced the peak ankle internal rotation angle compared to those for walking barefoot. Both walking in shoes with insoles and walking in shoes significantly reduced the toe-out angle compared to that for walking barefoot. However, no significant difference was observed in the peak knee varus moment. The results suggest that the foot insoles and shoes tested in this study might have influenced the ankle joint in OA patients. In view of the significantly decreased toe-out angle of the foot and increasing trend in the knee varus moment, the use of shoes with insoles may be unsuitable for knee OA patients.

What is a medial arch support?
oh, and what is knee arthritis?

HansMassage · Mar 31, 2015

An arthrose is a joint an itis is an irritation. If the patient points to a joint and says it hurts the doctor translates joint hurts to arthritis and he or she has a diagnosis.
Yes Paul exactly what part of the foot were thy supporting and for what purpose?
