Knee Replacement FAQs
What is knee replacement?
Knee replacement is a surgery where damaged parts of the knee joint are removed or smoothed and replaced with an artificial joint made of metal and plastic. This surgery replaces worn-out cartilage and helps reduce pain. It can also help you move more easily and get back to normal activities. In some cases, it can help straighten legs that have become bowed or knock-kneed over time.

FAQs
You may need knee replacement surgery if:
- Pain makes it hard to do everyday activities like walking, climbing stairs, or getting in and out of chairs
- You have knee pain even when resting
- Your knee is swollen and doesn’t improve with rest or medicine
- You cannot fully bend or straighten your knee
Yes. Surgery is usually recommended only after other treatments have been tried. These may include:
- Medications
- Injections
- Physical therapy
- Other types of surgery
The artificial knee can be attached using cement, or a mix of cemented and non-cemented parts. Your surgeon will decide what is best for you.
Most patients begin walking and moving their knee the day after surgery. Moving early helps improve blood flow and lowers the risk of blood clots and swelling. Many patients go home or to a rehab center within about three days.
Recovery varies by person, but most patients:
- Use a walker, crutches, or a cane for 3 to 6 weeks
- Return to light daily activities (like driving) in 3 to 6 weeks
- Fully recover in about 3 to 6 months
Like any surgery, there are some risks, but serious problems are not common. The most common issue is blood clots. To help prevent them, doctors may use:
- Compression socks
- Inflatable leg sleeves
- Blood-thinning medications
With modern medications and a dedicated care team, most patients are kept comfortable during recovery after surgery.
