What is Total Knee Replacement?
Total knee replacement is a surgery that replaces a damaged knee joint with an artificial one. Doctors often suggest this procedure when knee pain and stiffness limit daily life. Many people ask about total knee replacement because it can help restore movement and reduce pain. During the surgery, the doctor removes the damaged parts of the knee and puts in metal and plastic parts. These new parts work like a healthy knee joint. According to the World Health Organization (WHO), this surgery is safe and helps many people walk better.
Who Needs Total Knee Replacement? (Indications)
Not everyone with knee pain needs surgery. However, some people benefit more than others. Doctors may suggest total knee replacement if:Pain is severe and does not improve with medicine or therapyKnee pain makes it hard to walk, climb stairs, or get up from a chairOther treatments, like injections or braces, do not helpThe knee is stiff or swollen most of the timeX-rays show serious joint damage
For many, these signs mean it is time to consider knee replacement surgery.
Symptoms Leading to Surgery
Often, people notice certain symptoms before surgery becomes an option. For example, you may feel:Constant knee pain, even at restSwelling that does not go awayStiffness, especially in the morningDifficulty bending or straightening the kneeGrinding or clicking sounds in the joint
Because these symptoms can worsen over time, it is important to talk to your doctor early.
Causes of Knee Damage
Many things can damage the knee joint. The most common cause is osteoarthritis, which wears away the joint over time. Other causes include:Rheumatoid arthritis, which is swelling caused by the immune systemOld injuries, like broken bones or torn ligamentsInfections that harm the jointObesity, which puts extra stress on the knee
Since these problems can get worse, early care is important.
Diagnosis and Evaluation
First, your doctor will ask about your symptoms and medical history. Next, they will check your knee for swelling, movement, and pain. Often, doctors use X-rays or MRI scans to see inside the joint. Blood tests may also help rule out infections or other problems. Because every patient is different, your doctor will decide the best tests for you. The Centers for Disease Control and Prevention (CDC) recommends seeing a specialist for a full evaluation before surgery.
