Analysis of the Functional Impact of Total Knee Arthroplasty Using Quantified Gait Analysis and Proprioceptive Evaluation

To join this study, you need to be an adult who has severe knee arthritis (gonarthrosis) that doctors have said needs a full knee replacement. This means your arthritis should be mainly in your knee, and your doctor thinks surgery is the next step for you.

There are also some reasons why you might not be able to join. For example, if you have other health conditions that affect your balance or how you sense your body's position, like Parkinson's disease or effects from a stroke, you wouldn't be able to participate. Also, if you have problems with your memory or thinking, or if you can't walk without help for at least six months, or struggle to get up from a chair without using your arms, this study might not be right for you. Your ability to do daily tasks independently will also be checked.

If you decide to take part in this study, the researchers will closely monitor your knee and how you move, both before and after your total knee replacement surgery. You will likely have several appointments where specific tests will be carried out. These tests will include a 'quantified gait analysis,' which uses special sensors to measure your walking patterns very precisely. You might also perform certain everyday tasks, and your ability to sense your knee's position (proprioception) will be checked.

These assessments will happen before your surgery and again at specific times afterward. You'll also be asked to share your thoughts and feelings about your knee's function and your overall satisfaction. The study typically involves a period before surgery, the surgery itself, and then follow-up assessments for several months to understand the long-term impact. There won't be any new medications prescribed specifically for the study; it focuses on evaluating the effects of your planned surgery.
