Pros and Cons of Partial Knee Replacement

According to the CDC, nearly 33 Million US Adults suffer from Osteoarthritis. AT certain age, your doctor may recommend you a Partial or Unicompartmental Knee Replacement procedure to get rid of your symptoms. It’s generally prescribed to people having Osteoarthritis and can be performed quickly. Consider the pros and cons of Partial Knee Replacement before going for a total knee replacement. It may not be a long-lasting solution to the problems but should get you the right movement and motion you need. So, let’s jump in to find out what you need to know.

What are the Pros of Partial Knee Replacement?

After many years of continuous arthritis, people who need full knee replacement might think they have no other option. Even though a partial knee replacement may not cure the problem, it has big advantages. You can still perform daily routines and help your body heal itself naturally instead of simply replacing damaged parts with synthetic substances. It’s a standard procedure before knee replacements to become successful. Here are some Pros of Partial Knee Replacement you should know.

1. Partial Knee Replacement is Minimally Invasive

The procedure can last up to 1 to 2 hours in duration. Partial knee replacement surgery is a minimally invasive procedure used to replace only the damaged portion of the knee joint. This process is an alternative to a total knee replacement for some people. During partial knee replacement surgery, the damaged parts are removed.

The ends of these bones are then shaped and prepared for new prosthetic components to be attached. These new components will replace the joint surfaces and support the patient's weight when walking. Partial knee replacement surgery is performed with the patient under general anesthesia, which means the patient is asleep.

2. Quick Recovery Time is one of the Pros of Partial Knee Replacement

Partial knee replacement surgery can have you feeling better in no time. Patients are often able to walk without assistance shortly after the surgery. A partial knee replacement procedure is a minimally invasive surgical option that replaces or resurfaces only one part of the knee.

3. There is Minimal Discomfort in Partial Knee Replacement

A partial knee replacement procedure results in little to no discomfort. The surgery is minimally invasive and results in less pain and swelling than a traditional knee replacement. When it is time to decide on knee replacement, you need to consult with an Orthopaedic Surgeon. This will allow you to discuss your options and determine if partial knee replacement surgery is right for you.

4. Partial Knee Replacement Retains Natural Knee Motion

A partial knee replacement is a surgery to replace only the diseased or damaged parts of your knee, retaining much of your natural knee motion. A partial knee replacement is best for individuals with osteoarthritis in one part of the knee, who have a good range of motion and do not need to walk long distances.

Knee replacements are designed to relieve pain from arthritis by replacing damaged or worn-out parts of the knee joint. The knee is an important joint that allows us to walk, run, climb stairs and throw. It's a complex joint of many moving parts, including bones, ligaments, cartilage, tendons, and muscles.

5. Low Risk

Partial knee replacement surgery is a less invasive surgical procedure used to replace only the damaged parts of the knee joint. It can be done using minimally invasive technology or using open surgery. Being minimally invasive, the procedure requires general anesthesia and can be done through small incisions.

These small incisions are made to access the joint through which a surgeon implants the prosthesis without any additional incisions. As a result, it requires less time to recover and has fewer complications.

What are the Cons of Partial Knee Replacement Procedure?

Although Unicompartmental or Partial Knee Replacement works in some cases, you may need to undergo total knee replacement for moderate to severe conditions. As with any procedure that affects a person's health, it is important to be aware of all the cons of partial knee replacement, especially before getting a medical procedure done. Here are some aspects you need to consider first and foremost.

1. Not a Permanent Solution

A partial knee replacement surgery is not a permanent solution, but it can help you feel better and move more easily. The surgery is a way to relieve pain and improve function in people with arthritis in the knee, but it is not a cure. Your knee joint will continue to degenerate and may require further surgery. One of the many cons of partial knee replacement is that it will last for 8 to 10 years after which, you’ll likely suffer the same problems.

2. Partial Knee Replacement can Worsen Osteoarthritis

According to a study by researchers at Johns Hopkins Medicine, partial knee replacement can worsen Osteoarthritis. The study found that people who had a partial knee replacement were more likely to experience a worsening of their Osteoarthritis than those who did not have surgery.

3. Infections are Rare Cons of Partial Knee Replacement

Partial knee replacement can result in infections, which can be serious and may require additional surgery. You should know what to look for and when to call your doctor.

Since the artificial joint replaces damaged cartilage and not bone, there is a risk of loosening, so you need to understand the symptoms of a knee replacement that needs to be replaced. Different infections of partial knee replacement include Redness, Warmth, or pain around the incision, or an increase in swelling.

4. Loosening of Implants

Loosening of implants after partial knee replacement is a common complication in one-third of patients. This problem can cause pain and joint instability. However, the study, published in the journal Arthritis Care & Research, found no differences in pain, knee instability, or joint strength between patients who received a certain type of cement, known as methyl methacrylate (MMA), and those who did not.

5. Arthritis may Develop Even after Partial Knee Replacement

Even after Partial Knee Replacement surgery, arthritis may develop. This is because the pain of arthritis is similar to the pain of partial knee replacement. Most of the symptoms of Osteoarthritis after Partial Knee Replacement are either related to pain or pain-related dysfunction in the knee.

Conclusion on the Pros and Cons of Partial Knee Replacement

Even though the procedure is minimally invasive and less risky, you need to follow certain precautions to avoid further complications. Stop smoking, consult your healthcare provider if you are on medication, and keep following the post-surgery measures. Keep all the Pros and cons of Unicompartmental Knee Replacement Procedure in mind before and after the surgery.
