Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A Project Examiner will conduct preliminary screening over the phone. Participants will undergo examination by the Project Examiner and the Project Podiatrist to ensure they fulfil selection criteria. An x-ray will be performed to ensure varus knee joint malalignment. Baseline testing including assessment of knee pain and MRI measurements of knee cartilage volume will be performed on all subjects, following whoich the particpant will be randomised into one of two groups: (i) laterally wedged insoles or, (ii) control insoles. The intervention period will be 12 months after which participants will be reassessed.
