Visualisation of knee replacement rehabilitation exercises in the home

Introduction and aim: Osteoarthritis of the knee is a degenerative joint disease associated with ageing, characterised by excessive pain and disability. The joints that can be affected include knees, hips, fingers and lower spine. As life expectancy is rising across Europe, the population of older adults affected by osteoarthritis is set to increase [1]. Knee replacement is an effective treatment for severe knee osteoarthritis where the worn knee joint is replaced with ceramic or metal implants. However to optimise functional recovery a period of physical rehabilitation is routinely prescribed [2]. In the UK, the bulk of the acute post-operative rehabilitation takes place in the patient's home and not in the hospital or rehabilitation centres. As part of the standard routine practise, patients are given training while in the hospital and also receive a phone call check-up 10–14 days post operatively and return for a clinical check-up after six weeks.
