Knee Replacement Surgery: An Overview

Knee replacement surgery, also known as knee arthroplasty, is a surgical procedure to replace a damaged or diseased knee joint with an artificial joint, typically made of metal, plastic, or ceramic. This procedure is usually recommended for individuals who have severe knee pain, stiffness, and reduced mobility that has not improved with non-surgical treatments, such as physical therapy, medications, or injections.

Types of Knee Replacement Surgeries

There are two main types of knee replacement surgeries: total knee replacement and partial knee replacement. The type of surgery performed depends on the extent of the damage to the knee joint. In a total knee replacement, the entire knee joint is replaced, whereas in a partial knee replacement, only the damaged part of the knee joint is replaced.

Preparation for Knee Replacement Surgery

Before undergoing knee replacement surgery, several tests and evaluations are performed to determine if the patient is a suitable candidate for the procedure. These tests include a physical examination, blood tests, X-rays, and MRI scans. The patient will also be required to stop taking certain medications, such as blood thinners, and avoid eating or drinking anything for a specific amount of time before the surgery.

The Knee Replacement Surgery Procedure

The procedure for knee replacement surgery typically takes 1-2 hours and is performed under general anesthesia or spinal anesthesia. The surgeon will make an incision on the knee to access the damaged joint and remove the damaged cartilage and bone. The artificial joint is then attached to the remaining bone using cement or another fixation method. Finally, the incision is closed with sutures or staples, and the patient is moved to a recovery room.

Recovery and Rehabilitation

After the surgery, the patient will spend several days in the hospital under close observation to monitor their recovery. Physical therapy will begin as soon as possible to help the patient regain strength and mobility in the knee joint. The patient will also be given pain medications and antibiotics to manage pain and prevent infection. Recovery time varies depending on the individual, but most patients can resume normal activities within a few months.

Risks and Complications

Like any surgery, knee replacement surgery carries risks and complications, including infection, blood clots, nerve damage, and implant failure. The risk of complications can be minimized by following the pre- and post-operative instructions provided by the surgeon and taking steps to reduce the risk of infection.


Knee replacement surgery is a common procedure that can significantly improve the quality of life for individuals with severe knee pain and mobility issues. It is important to work closely with the surgeon and follow their instructions before and after the surgery to minimize the risk of complications and ensure a successful recovery.

Avoid These 5 Mistakes After Knee Replacement Surgery

Knee replacement surgery can be a life-changing procedure for those with severe knee pain and limited mobility. However, proper post-operative care is crucial for a successful recovery. In this article, we’ll go over four common mistakes that people make after knee replacement surgery and how to avoid them.

  1. Endlessly Focusing On Quad Muscles

After knee replacement surgery, it’s common for quad muscles to be weak and not turn on. While it’s important to work on activating them in the beginning, once they are functioning properly, it’s time to move on to other muscle groups. Focusing solely on quad muscles can lead to over-dominance, which may have contributed to the knee osteoarthritis that led to the surgery in the first place. Instead, work on strengthening other muscle groups, such as the glutes.

  1. Not Taking Enough Pain Medication

It’s understandable to want to avoid taking pain medication, but after knee replacement surgery, it’s important to follow your doctor’s recommendations. Pain management is crucial for a successful recovery, and trying to tough it out can impede progress. Taking medication as prescribed can make rehabilitation easier and less painful.

  1. Not Drinking Enough Water

Proper hydration is crucial for healing after knee replacement surgery. All the processes that happen inside our cells occur within water, and not drinking enough can lead to slower healing and increased pain. Aim to drink two to three liters of water per day, but adjust based on your doctor’s recommendations and your individual needs.

  1. Comparing Your Progress With Others

It’s easy to fall into the trap of comparing your progress with others. However, every individual’s recovery process is unique, and comparing yourself to others can be discouraging. Remember that everyone heals at their own pace, and focus on your own progress and goals.

5. Pushing Yourself Too Soon, Too Fast

Pushing yourself too soon and too fast after knee replacement surgery can have several negative effects on your recovery and overall outcome. Here are some potential consequences:

  1. Delayed Healing: Your body needs time to heal after knee replacement surgery. If you push yourself too soon and too fast, you may delay the healing process and potentially damage the surgical site. This can lead to complications such as infection, swelling, and pain.
  2. Increased Pain: Pushing yourself too soon and too fast can lead to increased pain in the knee joint. This can be due to the strain put on the joint, as well as the increased inflammation and swelling that can occur.
  3. Reduced Range of Motion: If you try to do too much too soon after knee replacement surgery, you may inadvertently limit your range of motion. This can happen if you try to move your knee too much or too forcefully before it’s ready, which can cause scar tissue to form and restrict your movement.
  4. Re-Injury: Pushing yourself too soon and too fast after knee replacement surgery can increase your risk of re-injury. This is because your knee joint is still fragile and vulnerable to damage, and if you overdo it, you may put too much stress on the joint and cause further damage.
  5. Longer Recovery Time: Finally, pushing yourself too soon and too fast after knee replacement surgery can actually lengthen your overall recovery time. If you delay healing or re-injure the joint, you may need to spend additional time in physical therapy or even require another surgery to correct the issue.

Overall, it’s important to follow your doctor’s recommendations and take things slow and steady after knee replacement surgery. With patience and care, you can help ensure a successful and speedy recovery.

In conclusion, knee replacement surgery can be a life-changing procedure, but proper post-operative care is crucial for a successful recovery. By avoiding these four common mistakes, you can ensure that your rehabilitation is as smooth and successful as possible. Remember to listen to your doctor’s recommendations and take care of your body as it heals.
