Total Knee Replacement
If your knee is severely damaged by arthritis or injury, it may be hard for you to perform simple activities, such as walking or climbing stairs. You may even begin to feel pain while you are sitting or lying down.
If nonsurgical treatments like medications and using walking supports are no longer helpful, you may want to consider total knee replacement surgery. Joint replacement surgery is a safe and effective procedure to relieve pain, correct leg deformity, and help you resume normal activities.
The most common cause of chronic knee pain and disability is arthritis. There are many types of arthritis, most knee pain is caused by just three types: osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis.
A knee replacement (also called knee arthroplasty) might be more accurately termed a knee “resurfacing” because only the surface of the bones is actually replaced.
People who benefit from total knee replacement often have:
- Severe knee pain or stiffness that limits your everyday activities
- Moderate or severe knee pain while resting, either day or night
- Chronic knee inflammation and swelling that does not improve with rest or medications
- Knee deformity — a bowing in or out of your knee
The following symptoms may be the first warning of knee problems:
Pain is the most common complaint. It can vary from recurring vague discomfort to sudden, severe pain following an injury.
Swelling immediately following an injury is usually due to bleeding inside the joint. Swelling with clear fluid can come on more slowly and is a sign of some internal knee irritation.
Locking or “giving way” can be due to a variety of causes, but is most often associated with mechanical problem or a “loose body” in the knee.
Limited movement or stiffness may be noted at certain times of the day or may occur soon after injury.
Grinding or cracking may be noticed in the knee. This may indicate a roughening of the bone or articular cartilage.
If you have pain or any combination of these problems, it is important to see a doctor as soon as possible.
