Knee replacement surgery can seem intimidating, but understanding the basics can ease your mind. Did you know that over 600,000 knee replacements are performed annually in the United States? This common procedure helps people regain mobility and reduce pain. Knee replacement involves replacing damaged knee parts with artificial components, often made of metal and plastic. Recovery time varies, but most patients return to normal activities within six weeks. Surprisingly, many patients report significant pain relief and improved quality of life post-surgery. Whether you're considering this surgery or just curious, these 15 facts about knee replacement will provide valuable insights.
What is Knee Replacement?
Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint. This helps relieve pain and disability, often caused by osteoarthritis or other joint diseases.
-
The first knee replacement surgery was performed in 1968. Since then, the procedure has become one of the most successful surgeries in medicine.
-
Knee replacements can be partial or total. Partial knee replacement involves replacing only one part of the knee, while total knee replacement involves replacing the entire joint.
-
The materials used in knee replacements are typically metal and plastic. These materials are chosen for their durability and compatibility with the human body.
Why People Get Knee Replacements
Knee replacements are often necessary when the knee joint is severely damaged. This damage can be due to various conditions, leading to pain and impaired movement.
-
Osteoarthritis is the most common reason for knee replacement surgery. This condition causes the cartilage in the knee to wear away, leading to pain and stiffness.
-
Rheumatoid arthritis can also necessitate knee replacement. This autoimmune disease causes inflammation in the joints, leading to pain and damage.
-
Knee injuries, such as fractures or ligament tears, can lead to the need for knee replacement if they cause significant damage to the joint.
The Procedure of Knee Replacement
Understanding the procedure can help alleviate some of the anxiety associated with surgery. Here's a brief overview of what happens during knee replacement surgery.
-
The surgery typically lasts between one to two hours. During this time, the damaged parts of the knee are removed and replaced with artificial components.
-
General or spinal anesthesia is used during the procedure. This ensures that the patient does not feel pain during the surgery.
-
Post-surgery, patients usually stay in the hospital for a few days. This allows doctors to monitor recovery and manage any immediate complications.
Recovery After Knee Replacement
Recovery is a crucial part of the knee replacement process. It involves physical therapy and gradual return to normal activities.
-
Physical therapy begins almost immediately after surgery. This helps improve mobility and strength in the new joint.
-
Most patients can resume normal activities within three to six weeks. However, full recovery can take up to a year.
-
Pain management is an important aspect of recovery. Doctors often prescribe medications to help manage pain and inflammation.
Benefits and Risks of Knee Replacement
Like any surgery, knee replacement has its benefits and risks. Understanding these can help patients make informed decisions.
-
Knee replacement can significantly reduce pain and improve quality of life. Many patients report being able to return to activities they enjoyed before their knee problems.
-
There are risks associated with knee replacement, including infection and blood clots. However, these risks are relatively low and can be managed with proper care.
-
The artificial knee joint can last for 15 to 20 years. This means that many patients may only need one knee replacement in their lifetime.
