China489 participantsStarted 2026-04-16
Plain-language summary
This is a single-center retrospective cohort study to identify independent risk factors and develop a predictive nomogram for moderate-to-severe pain within 24 hours after Achilles tendon surgery.

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 study focused on identifying risk factors for moderate-to-severe pain after Achilles tendon surgery — based on what they found, does my personal profile put me at higher or lower risk for that kind of pain after my procedure?
2The trial developed a predictive nomogram for postoperative pain — is that tool something you or the surgical team could actually use before my operation to help plan my pain management?
3Since this was an observational study rather than a treatment trial, it doesn't test a new therapy — so how would the findings from this research actually change or improve the pain control plan you'd recommend for me after Achilles tendon surgery?
4The study is already completed, so results may be available — have the findings been published yet, and do they suggest any specific pain management strategies that might be worth discussing for my care?
5Given that this research identified risk factors for severe postoperative pain, are there steps we could take before my surgery — like adjusting medications or planning nerve blocks — to lower my chances of experiencing that level of pain?

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.
