AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with knee osteoarthritis who are scheduled for a first total knee replacement. Their walking will be measured with sensor insoles before surgery.
- Age
- 19 years and older
- Sex
- All sexes
- Disease stage
- Knee osteoarthritis, Kellgren-Lawrence grade 1-4. People must be able to walk on their own on level ground (FAC ≥ 3).
- Earlier treatment
- People must not have had a knee replacement on the same knee before.
Main reasons for not taking part
- The planned knee replacement is cancelled
- Earlier knee replacement on the same knee
- Nerve, muscle or bone disorders that affect walking
- Pregnancy or possible pregnancy
- Any condition the study doctor judges makes joining inappropriate

About the trial
What the trial wants to find out
This multicenter prospective observational study aims to evaluate whether preoperative clinical variables and wearable sensor-derived gait features can predict postoperative improvement after total knee arthroplasty (TKA). Participants will undergo standardized gait assessments using instrumented insoles and complete validated patient-reported outcome measures (PROMs). Prediction models including linear regression, random forest, and deep neural networks will be applied and their performance compared.
The group in the trial
- TKA Patients
Participants scheduled for primary unilateral total knee arthroplasty at either Yongin Severance Hospital or Gachon University Gil Medical Center. No intervention is assigned; all data are collected as part of observational evaluation.
Treatment: Instrumented Insole Gait Assessment
Questions to ask the study team
- How often do I need to come in, and for how long each time?
- Are travel costs paid?
- Can I keep my own doctor?
- What happens if I want to stop?
