Description of intervention(s) / exposure
Intervention: contra-lateral use of a cane to unload the affected medial knee compartment. Participants will be instructed to use the cane daily whenever walking for 3 months. Cane use and possible adverse events will be monitored in self-reported log books. Participants will receive reminders during the intervention to maximize adherence to cane use.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The person who will determine if a potential participant is eligible for inclusion in the trial will be unaware, when this decision is made, to which group the participant will be allocated. After collection of baseline measures, participants will have 50% chance being allocated to either the control or the intervention group. Allocation will be concealed in sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation schedule will be prepared by the study biostatistician using random permuted blocks and stratified by Kellgren-Lawrence grading of disease severity and body mass index.

Summary
Brief summary
Osteoarthritis (OA) is a major and costly cause of chronic musculoskeletal pain and disability in Australia. Patient self-management strategies are urgently needed. In knee OA, increased joint loading (forces acting across the joint) leads to worse knee pain and progressive structural joint deterioration. This project will investigate the impact of daily cane use, an easy and inexpensive self-help tool known to unload the knee, applied for 3 months on bone marrow lesion size on MRI in people with medial knee OA.
