Knee replacement surgery 1

Knee pain is a common issue battled by many. However, in some cases, knee pain can become excruciating to the point where the patient cannot walk or do any daily activities properly. This inability to perform everyday tasks due to excruciating knee pain makes a patient wonder if they must undergo a knee replacement surgery or if a knee replacement surgery is worth it. However, the decision to undergo knee replacement surgery is a personal one that requires careful consideration. Before deciding if a knee replacement surgery is worth it, there are several factors that are to be considered, including the risks and benefits of knee replacement surgery.

In this blog, we will delve into the topic of knee replacement surgery to learn if knee replacement surgery is worth it and how to make a decision about it. So, please keep reading.

When is knee replacement surgery needed? How to Make a Decision?

While knee pain in certain cases may be chronic and limit mobility, the decision to get a knee replacement surgery must be thoroughly thought through. Before deciding to get a knee replacement surgery, it is essential to consult with your doctor to discuss your condition, symptoms and other treatment options, if any. After studying your case thoroughly, your doctor will guide you. 

A knee replacement surgery decision may be needed in the following situations, 

1. Excruciating pain that doesn’t get better 

If you find yourself experiencing a lot of discomfort, pain and swelling in your knee along with limited mobility, like trouble walking or navigating the stairs, then it may be a sign that a surgical intervention is needed. Additionally, if your knee continues to pain, even during periods of rest or at night, it may be an indication of getting medical attention and considering the surgical option.

2. When other treatments did not work 

Before deciding to get knee replacement surgery, every patient starts with the available basic treatment approaches. If you have tried various treatment options such as lifestyle changes, losing weight, anti-inflammatory medications, cortisone injections, and physiotherapy to ease and alleviate the symptoms of knee pain and swelling, then you may be the ideal candidate for a knee replacement surgery. 

3.   A knee deformity 

In case your leg has become deformed due to an injury or if a deformity has been present since birth, knee replacement surgery can be a good treatment option. Knee replacement surgery is a great option for correcting deformed knee joints and restoring their normal functionality.

4.  Reduced quality of life

A knee replacement surgery may be a good option to consider if the knee pain is interfering with your everyday activities and limiting your mobility to perform basic tasks.

When is a Knee Replacement Surgery not meant for You?

While knee replacement surgery can be transformative for some patients, it may not be a good and suitable option for everyone. Certain factors that may indicate that the decision of knee replacement surgery is not meant for you may include the following, 

  • Medical conditions and risks: Having certain medical conditions can increase the risks associated with knee replacement surgery. For example, a doctor may not advise you to undergo a knee replacement surgery if you have certain health conditions such as uncontrolled diabetes, severe heart or lung disease, etc. These conditions may increase your risk of developing potential surgery-related complications. 
  • Infections: If you have any ongoing infections, then a surgery for knee replacement may not be the right option for you, as you will be at a risk of getting an infection in the new knee. 
  • Poor overall health: If you have a compromised immune system or various health issues, then it may influence the decision of a knee replacement surgery, as it could increase the risks of surgery or hinder the recovery process.
  • If the reason for joint pain is something else: If the knee pain you’re experiencing is due to other conditions, such as lower back pain, then you may not need a knee replacement surgery. Treating the cause will ease the symptoms of knee pain in such cases. 
  • Old age: While age alone is not a determining factor, older individuals who have limited life expectancy or significant age-related health conditions and weak immunity may not be ideal candidates for knee replacement surgery.
