Revision surgery on prosthetic knee implants is sometimes necessary for patients who have undergone a total knee replacement. In reoperations, the patient returns to the operating room to have their old prosthesis removed and their new one implanted.
In some cases, only one of the knee prostheses implanted during the first knee replacement treatment may need to be swapped out during a subsequent procedure known as a “revision knee replacement” (known as “revision total knee replacement”). A major revision like this one is a complex operation that needs careful preparation, specialised implants and instruments, a long window of opportunity within which to do the treatment, and the application of refined surgical skills.
When specific circumstances are met, a patient may be a candidate for knee revision surgery. If a patient’s prosthetic knee implant fails due to normal wear and tear or an infection, the patient may require knee revision surgery. In older individuals, a knee replacement implant can last for the remainder of their lives. In contrast, younger patients, particularly those who lead active lifestyles, are more prone to encounter knee prostheses that deteriorate over time.
Knee revision surgery is often done for the following reasons, among others:
Approximately 1-2% of patients who undergo a complete knee replacement develop an infection, and when this happens, knee revision surgery is typically required to treat the infection.
Instability manifests itself in the inability to maintain balance while standing or walking, and it occurs when the soft tissues surrounding the knee are unable to provide stability required for the knee to function properly.
When considerable scar tissue accumulates around the knee, as it does in some people, it can create stiffness, which in turn can impede a person’s range of motion. Over time, frictional wear and tear can cause prosthetic parts to loosen or break.
What to anticipate?
Prior to the Incision
Knee replacement surgery always calls for a general anaesthetic. If you prefer to be awake but numb below the waist, spinal anaesthesia is an option, whereas general anaesthetic will put you to sleep.
An intravenous antibiotic will be administered to you before, during, and after surgery to prevent infection. Numbness in the knee and its surrounding area may result from a nerve block, but it usually goes away after a period of therapy.
Within the framework of the procedure
To completely examine the insides of your knee, you’ll need to bend it. Before removing the damaged cartilage and bone from your knee joint, your surgeon will make an incision between 6 and 10 inches (15 and 25 cm) long and move your kneecap out of the way.
The surgeon will next fit the prosthetic joint components to the cleaned and sterilised joint surfaces. The doctor will flex and rotate your knee to check its range of motion and make sure it is stable before stitching up the wound. Typically, surgical procedures take around two hours.
After the surgery is completed
Following the completion of the treatment, you will be led to a secluded part of the recovery room, where you will be able to get some rest. There is a large amount of variance in the amount of time it takes for a patient to make a complete recovery after undergoing surgery from one individual to the next. The activities for the day can now be brought to a close, and a sizable percentage of the audience can be dismissed to go home. With the medication that your doctor has given you, you should be able to control the discomfort you are experiencing.
Regular foot and ankle mobility helps minimise the risk of edoema and blood clots. This is because it causes an increase in the amount of blood that flows to the muscles in the legs. Your medical professional may recommend that you take blood thinners and wear support tights or compression boots in order to further reduce the likelihood of developing edoema and blood clots.
You’ll need to do some breathing exercises on the regular and ramp up your activity level slowly. In order to get the most out of your replacement knee, a physical therapist will prescribe you particular exercises to undertake. After being discharged from the hospital, you will either continue your physical therapy sessions at home or find a local clinic.
Get in the habit of working out regularly as directed. Pay close attention to the wound care, nutrition, and exercise instructions given to you by your healthcare team if you want to get the most out of your rehabilitation.

What is knee revision surgery?
To correct the alignment of a damaged or diseased knee joint, surgeons perform a procedure called knee replacement (or arthroplasty, for short). In theory, it might reduce discomfort and let people get back to work.
During surgery, damaged bone and cartilage in the thighbone, shinbone, and kneecap are removed, and the patient’s natural joints are replaced with artificial ones (prostheses) constructed of metal alloys, premium plastics, and polymers. These artificial joints are created using the patient’s own natural joints. This procedure is performed on the patient after the native joints have been replaced with prostheses.
Metal alloys are used in the production of these replacement joints. Your mobility, stability, and strength in the knee will be evaluated by your orthopaedic surgeon before they make a decision on whether or not to do knee replacement surgery on you. With the use of an X-ray, one is able to assess the degree of severity of an injury.
Who really does require knee revision surgery?
If the patient’s prosthetic knee implant has been harmed as a result of an infection or normal wear and tear, knee revision surgery may be required. A knee replacement implant may become a permanent component of the patient’s anatomy in the case of an elderly patient. The likelihood of knee prosthesis degrading over time is higher in younger patients, especially those who lead active lifestyles.
This is particularly valid for patients who take part in sports. Patients who have had knee replacement surgery in the past are more susceptible to this. Compared to patients who don’t engage in such rigorous physical activity; patients who regularly engage in such strenuous physical activity, such as playing sports or going for long runs, have a higher risk of developing the illness.
In what circumstances is knee revision surgery required?
Surgery to replace the knee is often recommended for people who suffer from osteoarthritis because it can help lessen the excruciating pain that the condition causes. For the vast majority of patients who are in need of a knee replacement, normal day-to-day activities such as walking, climbing stairs, and getting out of seats become difficult to perform. Those who experience knee discomfort on a consistent basis may find it challenging to relax and unwind.
