Recovering after knee replacement means the weeks and months it takes for your body to heal and for you to regain strength and movement in your new knee joint. It is a process that requires patience, rest, and guided exercises.
Key facts
Yes, knee replacement is a very common and successful surgery, with hundreds of thousands performed each year worldwide.
It affects people of all ages who have had a knee replacement, most often older adults with severe arthritis, but also younger people with knee injuries or other conditions.
Recovery after knee replacement is monitored by your surgeon and physical therapist through regular check-ups. They will check your wound, range of motion, and strength.
Your surgeon will tell you how often you need to come back for visits. Expect to do exercises every day and gradually increase activity as your knee heals.
Treatment for recovery focuses on helping you heal safely and regain function. This includes managing pain, doing physical therapy, and taking care of your wound.
Your doctor may prescribe pain relievers and anti-inflammatory medicines to control discomfort and swelling. You might also be given blood-thinning medicine to prevent clots. Always take medicines exactly as prescribed and ask your pharmacist if you have questions.
For the first few weeks, you will need help with tasks like bathing, cooking, and getting around. Plan ahead for someone to assist you. Use a walker or crutches until your surgeon says it's safe to walk without them.
Eat a balanced diet rich in protein, vitamins, and calcium to help your bones and tissues heal. Drink plenty of water. Your physical therapist will give you specific exercises to do at home — do them regularly to improve movement and strength.
Recovery can be frustrating and sometimes painful. It is normal to feel down or anxious. Talk to your loved ones or your healthcare team about how you are feeling. Many people find that setting small, achievable goals helps their mood.
You can help prevent complications during recovery by following your care plan, keeping your wound clean, doing your exercises, and stopping smoking. To prevent future problems with your new knee, maintain a healthy weight and avoid high-impact activities.
Most people who have a knee replacement experience significant pain relief and improved mobility. With good rehabilitation and healthy habits, your new knee can last many years and greatly improve your quality of life.
