Knee Replacement Surgery in Singapore

What is Knee Replacement Surgery?

Known as knee arthroplasty, a knee replacement surgery involves removing the damaged or diseased bone and cartilage and replacing them with metal implants that act as artificial joints. The procedure aims to resurface damaged portions of the knee joint and improve knee function and relieve chronic knee pain that cannot be treated in any other way. The procedure may involve a total knee replacement, which involves replacing the entire knee joint, or a partial knee replacement, which consists in replacing only the damaged part of the joint.

When is Knee Replacement Surgery Needed?

Knee replacement surgery is typically needed when other treatments, such as medications, physical therapy, or injections, have failed to relieve chronic knee pain and improve knee function. It may also be recommended for patients who have various types of arthritis that can result in knee pain. Older adults are more likely to experience osteoarthritis where flexible tissue at the end of bones wears down over time, resulting in chronic pain. Rheumatoid arthritis, which causes inflammation of the synovial membrane, can also be another reason for pain and stiffness in knee joints. 

From the above, it is clear to see that common symptoms that may indicate the need for knee replacement surgery include severe knee pain, stiffness, swelling, limited range of motion, and difficulty performing everyday activities. 

Depending on the extent of damage, your doctor may suggest a knee replacement surgery. 

Who Usually Needs to Get a Knee Replacement Surgery?

Apart from elderly patients with osteoarthritis, knee replacement surgery may be an option for athletes in Singapore to recover from traumatic arthritis which causes damage to the cartilage of the knee due to injury and resume sports activities. 

When Will a Total Knee Replacement be Recommended?

A total knee replacement surgery is recommended when other treatments have failed to relieve knee pain or improve knee function. The decision to recommend the surgery is made by an orthopaedic surgeon based on factors such as the severity of knee pain, limitations in activities of daily living, and other medical conditions. For example, suppose an individual's knee is severely damaged by an injury, making it hard to perform simple daily activities like climbing the stairs. In that case, a total knee replacement might be an option. However, non-surgical, conservative treatments may be recommended first, and knee replacement surgery is not always necessary. 

What to Consider Before Knee Replacement in Singapore

Before undergoing knee replacement surgery in Singapore, there are a few things patients should keep in mind. For one, choosing a qualified and experienced surgeon and hospital or clinic where the surgery will be performed is crucial. Patients should also discuss potential risks or complications with their doctor and understand the rehabilitation process after the surgery.

In addition, patients should prepare for the surgery by following their doctor's instructions. This may include not eating or drinking anything for a certain amount of time before the surgery. 

What Happens During a Knee Replacement Surgery?

Prior to the surgery, general anaesthesia may be administered to put you to sleep during the procedure. Alternatively, you may opt for spinal or epidural anaesthesia to block any sensation in the lower half of the body. However, bear in mind that you will remain awake while undergoing knee replacement surgery. 

Once the anaesthesia takes effect, your doctor will make a cut down your knee to access the joint. They will then remove the damaged parts of the knee before fitting the metal implants in. There may be three implants, in total, to be attached to the femur, tibia, and patella surfaces in your knee. To complete the knee replacement surgery, a plastic articular spacer will be positioned between the metal components to improve implant stability.

Things to Note After Knee Replacement in Singapore

After undergoing knee replacement surgery in Singapore, it is important for patients to carefully follow their doctor's instructions for post-operative care and rehabilitation. This may include taking medications, performing prescribed exercises, and attending physical therapy sessions to regain strength and mobility.

Patients should also prevent infection by keeping the wound clean and dry and avoiding activities that could damage the new knee joint. Attending all follow-up appointments with the doctor is also crucial for monitoring progress and ensuring that the knee is healing properly. Patients should also report any unusual symptoms, such as fever, increased pain, or swelling, to their doctor as soon as possible.

Possible Risks Associated with Knee Replacement Surgery

Like any surgery, knee replacement carries certain risks. These may include infection, blood clots, nerve damage, or allergic reaction to anaesthesia. In some cases, the surgery may not be successful, and patients may experience complications such as stiffness or instability in the joint. As such, it is important to seek the advice of an orthopaedic specialist in Singapore.

Frequently Asked Questions About Knee Replacement Surgery in Singapore

1How do I know when it’s time to get a knee replacement?

The most common condition that requires knee replacement surgery is osteoarthritis, a condition that is characterised by the breakdown of joint cartilage. Other forms of arthritis, such as rheumatoid arthritis and arthritis arising from a knee injury, may also result in knee joint degeneration. Hence, younger people who do sports regularly in Singapore may also suffer from knee ailments that may require surgery. In this case, you can consult our sports injury doctor based in Singapore to find a suitable treatment for your condition. 

Surgery is usually recommended when non-surgical knee treatments fail to alleviate the pain. Depending on your condition, a partial or total knee replacement may be recommended. You may also need revision surgery 15 to 20 years after the initial surgery to repair worn-out prostheses. 

2How long does it take to recover from knee surgery in Singapore?
Patients typically stay in the hospital for 3 to 5 days after the knee replacement surgery, depending on the complexity of the procedure. You will be able to stand up with the help of crutches within 12 to 24 hours of the surgery, and you may continue to need crutches until around 6 weeks after the surgery. Painkillers will be prescribed to help you manage the pain, and it may take up to 3 months for the pain to completely subside. Full recovery may take at least a year.
3What percentage of total knee replacements are successful?
The success rate of total knee replacements varies depending on several factors, such as age, overall health, and severity of the condition. Generally, studies show that up to 95% of patients experience significant improvement in pain relief and overall function following knee replacement surgery, making it a treatment option to consider for those suffering from severe knee joint problems.
