Adductor Ratio in Severe Varus Gonarthrosis

Plain-language summary
The restoration of the joint line (JL) is essential for the proper functioning of Total Knee Arthroplasty (TKA). The exact position of JL can be determined using anatomical landmarks such as femoral condylar width (TEW), tibial tubercle, fibular head, and adductor tubercle during preoperative planning or intraoperatively. However, in cases of severe varus deformity in Type M gonarthrosis, it is unknown which method is most suitable for accurately determining the precise JL position. The aim of this study is to identify the most appropriate method for determining the JL position in Type M gonarthrosis. To achieve this goal, two groups of patients with Type 1A and Type M gonarthrosis will be compared by measuring preoperative values and comparing them with intraoperative reference values.

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.
1This trial is focused on measuring something called the 'adductor ratio' to determine the joint line during knee replacement — can you explain what that means in plain terms and why getting that measurement right matters for my outcome?
2Since this trial is listed as Phase NA, it seems more like an observational or measurement study rather than a drug or device trial — does participating mean my actual surgery or treatment plan would change in any way, or would it just involve additional measurements being taken during my procedure?
3I have severe varus gonarthrosis, which I understand means significant bow-legged knee deformity — is this study specifically relevant to my degree of deformity, and would my anatomy make me a good or poor candidate to discuss with the research team?
4If I'm already planning to have a knee replacement, how would my doctor's involvement in this trial affect decisions about my implant alignment or surgical technique, and could it introduce any additional risks compared to standard surgery?
5Before considering this trial, should I ask about what the standard methods for determining joint line placement currently are, and whether participating in this study would give me access to a potentially more accurate approach or simply contribute data for future patients?

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.
