How does knee surgery with a total knee prosthesis work?

A knee operation is a big step, but for many people with severe knee osteoarthritis, a total knee replacement (also: full knee replacement) ultimately offers more freedom of movement and less pain. In this blog, we explain step by step what to expect before, during, and after the operation, and how MotiMove supports you. What will you read in this blog?  - What is a total knee replacement? - When do you choose a knee replacement? - Preparing for the operation - How does the operation proceed? - What happens after the operation? - Frequently asked questions What is a total knee replacement? In a total knee replacement, the entire knee joint is replaced with an artificial joint made of metal and plastic. This is done when the cartilage is severely worn down, as in advanced osteoarthritis. The prosthesis ensures that you can move more smoothly again without constant pain. Read this blog if you want to know whether you need a full or partial knee replacement.  When do you choose a knee replacement? A doctor will only consider a knee replacement if: - The knee hurts constantly, even at rest - Your daily activities are limited (walking, climbing stairs, cycling) - Other treatments such as physiotherapy or injections no longer help - An X-ray clearly shows wear of the knee joint; you usually only receive a knee replacement with bone-on-bone wear.  Preparing for the operation Before the operation, you will have a screening at the hospital and often a consultation with the anesthesiologist. You will be asked to start exercises for strength and mobility before the procedure—this is where MotiMove already plays a valuable role. How does the operation proceed? - The operation usually takes 1.5 to 2 hours - You receive a spinal anesthetic or general anesthesia - The surgeon removes damaged cartilage and places the prosthesis - After that, you are taken to the recovery room and later to the ward What happens after the operation? - You often stand up the same day or the following day with assistance - In the first days, pain relief, wound care, and mobility are the focus - The knee is initially swollen, painful, and limited in range of motion Frequently asked questions (FAQ) How long does recovery take after a knee replacement?   Most people notice a clear difference after 6–12 weeks. Full recovery often takes 6 to 12 months. Can I play sports again after the operation?   Light activities such as walking, cycling, and swimming are actually recommended. Avoid intensive sports with twisting movements (such as tennis). Is the operation very painful?   The first weeks after the operation are painful, but with good pain relief and movement, it gradually improves. Can I use MotiMove before and after the operation?   Yes! The app helps you become stronger and more flexible beforehand, and after the operation it helps you safely build up movement. Download here!
