The Relationship of the Medial Longitudinal Arch Height With Clinical Features of Knee Osteoarthritis

Turkey (Türkiye)90 participantsStarted 2022-12-07

Plain-language summary

The goal of this observational study is to investigate the relationships between the medial longitudinal arch (MLA) height of the foot and clinical and radiological characteristics of knee osteoarthritis in adult patients 50 aged and over. The main questions it aims to answer are: * Is there any relationship between knee pain and disability in knee osteoarthritis and MLA height? * Is there any relationship between the radiologic severity of knee osteoarthritis and MLA height? * Is there any relationship between knee joint alignment in knee osteoarthritis and MLA height?

Inclusion Criteria: * Being 50 years old or older * Having a diagnosis of knee osteoarthritis according to the American College of Rheumatology Exclusion Criteria: * History of fracture or orthopaedic surgery involving lower limbs * Presence of neurological condition resulting in lower limb sensorimotor deficit * Having another inflammatory rheumatological disease * Having a malignant tumour with bone metastasis * Having lower limb oedema, lymphedema, skin and soft tissue loss that will prevent the evaluation of foot morphology (arch height index) * Severe neuropsychiatric disease or condition that interferes with communication * Having therapeutic injection into the knee joint in the last 3 months * Presence of any major trauma that aggravated knee pain in the last 6 weeks

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
