Knee replacement (also known as ‘knee arthroplasty’) is a major orthopaedic operation, and not something to rush into unduly! It involves opening up the knee joint and resurfacing the worn/damaged joint surfaces of an arthritic knee with metal surfaces, with plastic ‘washers’ in-between. Knee replacement is a big op, a fairly painful op, and it requires extensive difficult rehab afterwards. The more you can learn about knee replacement surgery in advance, then the better prepared you will be for the surgery, and the more likely you will be to pick the right surgeon and the right prosthesis for you, as an individual.

This website was written by one of London’s top knee surgeons, Mr Ian McDermott, and it is intended as an information resource to provide you with as much knowledge about knee replacement surgery as possible. However, sometimes, the more you read about a subject and the more you learn, the more questions you may end up having! This website is not intended to replace a proper face-to-face clinical assessment, but it will hopefully help inform you and guide you, so that you can ask the right questions of your own knee surgeon, and so that you can might the right decisions for you!
