A Multi-centre Study of Shoe-worn Insoles and Knee Osteoarthritis
Recruiting now · Not applicable
Conditions studied: Knee Osteoarthritis
In brief
Shoe-worn insoles (also known as orthotics) can provide symptomatic relief for people with knee osteoarthritis. However, given they act at the feet, and given that many people with knee osteoarthritis also report foot pain, it is important to assess the effects of these devices at both joints. We will conduct a multi-centre randomized pilot trial to determine feasibility and preliminary efficacy.

Who can join
Age: 50 and older. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- medial tibiofemoral OA defined as definitive osteophytes and joint space narrowing in the medial compartment, as confirmed with radiographs
- history of knee pain longer than 6 months
- average self-reported knee pain of at least 3 out of 10 (using an 11-point numerical rating scale with terminal descriptors of 0 = "no pain" and 10 = "worst pain imaginable") over the 6 months prior to baseline testing
- pain in the same foot/feet as the painful knee(s)
- ability to communicate in English
- show an immediate biomechanical response to the insoles. This final eligibility criterion will be determined from an in-person biomechanical assessment after participants have passed all previous eligibility screening.
You may not qualify if…
- radiographic evidence of more lateral tibiofemoral OA than medial
- knee surgery or intra-articular injection within the previous 6 months
- current or recent (within 6 months) corticosteroid use for any reason
- presence of a systemic arthritic condition
- history of knee joint replacement or tibial osteotomy
- any other condition affecting lower limb function
- current usage of shoe-worn insoles, or planning to acquire footwear modifications in the next 6 months
- any previous experience with insoles that resulted in increased lower limb pain or a self- or clinician-initiated termination of use.
Where it is running
- Motion Analysis and Biofeedback Laboratory — Vancouver, British Columbia, Canada (enrolling)
