Key Takeaways:
Arthritis is an inflammation of the joints that can cause pain and stiffness, often worsening over time.
Knee replacement surgery can "cure" arthritis in the knee by removing the arthritic surfaces and alleviating associated symptoms.
Despite the effectiveness of knee replacement surgery, it does not cure arthritis in other parts of the body.
There are several ways to manage arthritis pain, including activity modifications, maintaining a healthy weight and using heat and cold therapies.
It's important to consult a healthcare provider if you experience persistent pain, swelling or stiffness in your knee.
Arthritis is a common condition that affects millions of people worldwide, causing pain and reducing mobility. According to the CDC, 24% of all adults in the US have arthritis. That is 58.5 million people.
One of the most frequently asked questions in orthopedic practice is, "Will knee replacement surgery cure arthritis?" This article aims to provide a comprehensive answer to this question.
What is Arthritis?
Arthritis refers to inflammation of the joints, causing pain and stiffness that can worsen over time. There are various types of arthritis, with osteoarthritis and rheumatoid arthritis being the most common. The knee is one of the joints most frequently affected by arthritis, which can significantly impair an individual's ability to move around comfortably.
Does Knee Replacement Surgery Get Rid of Arthritis?
Knee replacement surgery, medically known as arthroplasty, is a common procedure for treating severe arthritis in the knee. When performing this surgery, the surgeon removes all of the arthritic surfaces within the knee joint. This process also involves removing the anterior cruciate ligament (ACL), possibly the posterior cruciate ligament (PCL) and the menisci (meniscus). Furthermore, any osteophytes (bone spurs) are also removed.
The ultimate goal of a knee replacement is to alleviate the pain caused by arthritis, restore joint function and improve the patient's quality of life. Thus, to a large extent, knee replacement surgery can be said to "cure" arthritis in the sense that it removes the arthritic surfaces of the knee and alleviates associated symptoms.
Can You Still Have Arthritis After Knee Replacement Surgery?
While knee replacement surgery effectively removes the arthritis from the knee joint, it's important to understand that it doesn't cure arthritis in the entire body. If you have arthritis in other joints, those will remain unaffected by the knee replacement surgery.
Moreover, a small number of patients may experience continued pain after knee replacement surgery. This could be due to various reasons, including infection, implant problems or the development of arthritis in the hip or foot altering the way you walk.
Preventing Arthritis
While arthritis isn't fully preventable due to factors such as age and genetics, there are lifestyle changes that can reduce the risk or slow its progression:
Maintain a healthy weight: Extra weight puts additional pressure on your joints, including your knees.
Regular exercise: Low-impact activities can help strengthen muscles and keep joints flexible.
Healthy diet: Foods rich in antioxidants and Omega-3 fatty acids have been shown to have anti-inflammatory properties.
Protect your joints: Using the correct technique when lifting or carrying items can help avoid unnecessary stress on your joints.
How Can I Ease Arthritis Pain?
There are various ways to manage arthritis pain, and they often work best in combination. They include:
Regular physical activity to strengthen the muscles around the joints and increase flexibility
Maintaining a healthy weight to reduce stress on the joints
Using heat and cold therapies to relieve pain and stiffness
Over-the-counter pain relievers and anti-inflammatory drugs
Physical therapy and occupational therapy
Assistive devices like braces, canes, or shoe inserts
Cortisone (steroid) injections into the knee joint
In severe cases where these methods are not effective, surgical options like knee replacement may be considered.
What to Expect During a Knee Replacement Surgery
Knee replacement surgery is a relatively common procedure but is still a major surgery. It typically takes between 1 to 2 hours. The surgeon will remove the damaged cartilage and bone from your knee and replace it with an artificial joint made of metal and plastic. You'll be given anesthesia to ensure you're pain-free during the operation.
Post-surgery, the medical team will monitor your recovery, manage any pain and usually get you on your feet with a walking aid. Some patients will undergo surgery in a same-day setting where they will be discharged hours after the procedure. All other patients will typically be discharged from the hospital to home within 24 hours of the procedure.
Recovery and Rehabilitation After Knee Replacement
Recovery from knee replacement surgery is a gradual process. Initial recovery, where you can move about and take care of daily activities independently, typically takes about 2-4 weeks. Full recovery can take up to 2 months, or longer in some cases.
Physical therapy is a crucial part of recovery, helping to restore strength and mobility in your knee. It's important to stick to your rehabilitation program to achieve the best possible outcome.
Pain management, wound care and prevention of blood clots are also key aspects of the post-surgery period.
When to Consult a Doctor
If you're experiencing persistent pain, swelling or stiffness in your knee that limits your daily activities or affects your quality of life, it's time to seek medical advice.
Early diagnosis and treatment can often slow the progression of arthritis and reduce damage to the joints. If you've already been diagnosed with arthritis and your symptoms have worsened, or if conservative treatments aren't providing relief, it may be time to discuss surgical options like knee replacement with your healthcare provider.
Knee replacement surgery can effectively "cure" arthritis in the affected knee by removing the diseased parts of the knee joint. However, it's crucial to have realistic expectations and understand that the surgery won't cure arthritis in other parts of the body. Always consult with your healthcare provider to discuss the best treatment options for your specific situation.
