A knee replacement is a surgery to replace a damaged knee joint with an artificial one made of metal and plastic. It's done to relieve severe pain and improve movement when other treatments haven't helped.
Key facts
Yes, knee replacement is very common. Thousands of people have the surgery each year, and the number is growing as people live longer and stay active.
It mostly affects people over 50, especially those with advanced knee arthritis. It can also affect younger people if the knee is severely damaged by injury or disease.
Your doctor will ask about your symptoms, examine your knee, and check how well you can move it. They will also review your medical history and may order imaging tests.
If you are considering knee replacement, your doctor will discuss the risks, benefits, and what to expect. You may see a specialist (orthopedic surgeon) who will explain the surgery and preparation steps.
Before knee replacement, doctors recommend trying non-surgical treatments first. If they don't provide enough relief, surgery can help. Preparation includes getting your body and home ready for recovery.
Doctors may prescribe pain relievers, anti-inflammatory medications, or steroid injections to reduce pain and swelling before surgery. They might also recommend physical therapy to improve strength and range of motion. Always take medications exactly as prescribed and tell your doctor about any other medicines or supplements you take.
After knee replacement, most people need several weeks of recovery. You'll use a walker or crutches at first. Physical therapy is key to regain movement and strength. By 3 months, many people can walk without aids. Full recovery can take up to a year.
Eat a balanced diet rich in protein, vitamins, and minerals to help healing. Include calcium and vitamin D for bone health (dairy, green leafy vegetables, fortified foods). Avoid too much salt and sugar. Do the exercises your physiotherapist gives you – they are designed to restore movement and strength safely.
Recovery can be emotionally challenging. It's normal to feel frustrated, down, or anxious. Talk to friends, family, or a counsellor. If you have thoughts of harming yourself, contact a crisis line or your local emergency number immediately. You are not alone.
You can't always prevent the need for knee replacement, but you can reduce your risk of severe knee arthritis. Keeping a healthy weight, staying active, and avoiding knee injuries are important steps.
For most people, knee replacement dramatically reduces pain and improves mobility. It allows them to enjoy daily activities again. While recovery takes time and effort, the results are usually very good.
