Benefits of Early Proprioceptive Re-education Without Visual Information After Total Knee Arthroplasty
France66 participantsStarted 2026-03
Plain-language summary
Osteoarthritis is a common and disabling joint disease, affecting 4.7% of men and 6.6% of women in France. It causes pain and impaired joint mobility, as well as a reduction in proprioception due to damage to intra-articular mechanoreceptors. In the long term, gonarthrosis can lead to limitations in activities of daily living and increase the risk of falls and institutionalisation.
Total knee arthroplasty is an effective treatment for reducing pain and improving functional capacity. However, 50% of patients operated on are not satisfied with the results obtained at 6 months, and between 37% and 55% experience no significant improvement in their functional mobility. It is therefore important to better define the modalities of rehabilitation interventions in order to improve their efficiency and the functional benefits for the patient.
Proprioception, the visual system and the vestibular system are the three major systems involved in posture and balance. Rehabilitation interventions aimed at improving balance involve these three inputs and their interaction. Studies have shown that proprioceptive rehabilitation can significantly improve balance and gait in patients who have undergone total knee arthroplasty. However, visual feedback may hinder the development of balance skills by limiting the use of other sensorimotor systems.

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.
