Research summary
Is a single accelerometer repeatable and reliable in its measurement of side-to-side knee movement during walking and stepping, and does this relate to failure and instability following total knee replacement?
Knee instability following total knee replacement is a leading cause of dissatisfaction, pain and ultimately failure, leading to revision surgery. However, an objective method of describing the size of this instability does not exist, and current methods of investigating it are cumbersome, involving expensive equipment and specialist facilities. Developing a small, inexpensive and easy to use tool that will allow objective evaluation of instability will allow a better understanding of the condition for clinicians, allowing better evaluation and understanding for individual patients, and the development of treatment plans for the patient group. Patients will be recruited from orthopaedic knee clinics at the Golden Jubilee National Hospital, comprising of people who have had a total knee replacement and require re-operation for failure, and a control group who have had a successful total knee replacement. All research will be carried out in the gait laboratory at the University of Strathclyde. The study will involve measurement of walking and stair ascent/descent using the current test methods (gait analysis with multiple cameras and reflective markers) and an accelerometer attached with velcro to the lower leg. Testing will take approximately one hour, and participants will be asked to return for a second session to ensure repeatability of the system. Funding has been provided by the West of Scotland Orthopaedic Research Society.
