Knee Replacement: Frequently Asked Questions

As people age, knee pain can become a reality for many. Although joint disorders are common, when the pain worsens and is not adequately treated, it can compromise quality of life, making surgery necessary. Let’s look at the answers to the most frequent questions regarding knee joint pain, conservative therapies, surgical procedures, and recovery times.

Why Does My Knee Hurt?

Knee pain can be caused by various conditions, such as congenital problems, developmental difficulties, or trauma. However, the most common cause is arthritis, a condition that frequently affects people over 50. It’s important to note that the severity of arthritis is not necessarily related to age: you could be 50 and suffer from advanced, painful arthritis, or 80 with a mild form of the disease.

What Are the Non-Surgical Treatment Options?

The first approach is often conservative and may include physical therapy, medications, injections, or the use of braces. These treatments can be effective for many people. However, if significant improvements are not achieved, it may be necessary to consider surgical intervention.

Does Losing Weight Help Relieve Knee Pain?

Yes, there is a clear correlation between weight loss and improvement in arthritic conditions, especially in the knees and hips. For overweight patients, losing weight can alleviate joint pain and improve outcomes of any potential prosthetic surgery. In fact, many facilities require patients to reach an ideal weight before surgery to optimize recovery times and the effectiveness of the intervention. However, losing weight is not easy. If you already suffer from joint pain, it’s advisable to follow a low-impact exercise program, such as cycling, using an elliptical, or swimming. These activities help burn calories without exacerbating the pain.

Does Arthritis Disappear After Knee Replacement?

Yes, knee replacement surgery eliminates arthritis in the joint by replacing the damaged parts with an artificial knee. This implant consists of components made of metal and high-density polyethylene (plastic). In younger patients, ceramic materials are preferred due to their greater wear resistance compared to other components.

How Long Does a Knee Prosthesis Last?

Thanks to continuous technological advancements, a knee prosthesis can last between 20 and 30 years. For patients undergoing the procedure at 60 years or older, the prosthesis should last for the rest of their lives.

What Are the Recovery Times After Surgery?

After knee replacement surgery, a care period will be necessary for the first two or three weeks, as the patient will not be able to move easily. At home, the use of a walker and support may be needed to perform daily activities. Driving will be discouraged for about a month. Physical therapy sessions usually last six to eight weeks to promote complete recovery.
