About Knee Replacement Surgery

The knee is a complex joint that connects the bones of the legs. Knee replacement surgery, also known as knee arthroplasty, is conducted when the knee’s bones and cartilage are severely worn down by arthritis or any injury. The replacement parts, also called prostheses, are generally made of metal and plastic and last for a long time. If traditional medication, therapy, injections and more have not brought relief to the patient, they may be eligible for knee replacement surgery.

Types of Knee Replacement Surgery

There are many types of knee replacement surgeries based on the extent of the procedure and the specific needs of the patient. Some common types are:

Total Knee Replacement (TKR)

Also known as total knee arthroplasty, total knee replacement (TKR) surgery involves replacing the entire damaged knee joint with an artificial prosthesis. The prosthesis includes metal components for the femur and tibia and a plastic spacer in between to allow smooth movement.

Partial Knee Replacement (PKR)

Partial knee replacement surgery (PKR) is performed when only one compartment of the knee is affected by arthritis or damage. In PKR, only the damaged portion of the knee joint is replaced with a prosthetic implant, preserving healthy bone and ligaments.

Bilateral Knee Replacement

Bilateral knee replacement surgery involves replacing both knees in a single surgical procedure. It is typically performed for patients with significant arthritis or damage in both knees, allowing them to undergo a surgery and recovery period instead of two separate ones.

Complex or Revision Knee Replacement

This surgery is performed when a previous knee replacement has failed or requires correction. Complex or Revision knee replacement involves removing the existing prosthesis and replacing it with a new one to address complications, instability, or wear and tear.

Minimally-Invasive Knee Replacement

In this approach, smaller incisions are made compared to traditional knee replacement surgery. Minimally invasive knee replacement surgery aims at minimising muscle and tissue disruption, potentially leading to shorter hospital stays, reduced scarring, and faster recovery times.

Reasons for Knee Replacement Surgery

The procedure is recommended when other treatments, such as medication, physiotherapy, or lifestyle modifications, have failed to provide relief from knee pain or restore mobility. Some conditions may also lead to the need for a knee replacement, including:

Osteoarthritis

Osteoarthritis is a common degenerative joint disease, it may occur when the protective cartilage that cushions the bones in the knee joint wears away, leading to pain, stiffness, and limited mobility.

Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune condition causing inflammation and damage to the joints, including the knees. The resulting pain, swelling, and stiffness can make it difficult to perform daily activities.

Post-traumatic Arthritis

Post-traumatic arthritis is a form of arthritis that may develop after a knee injury, such as a fracture or ligament tear. The resulting damage to the joint can lead to pain, swelling, and decreased mobility.

Avascular Necrosis

Avascular necrosis is a condition in which the bone tissue in the knee joint dies due to a lack of blood supply. It can be caused by trauma, medications, or medical conditions such as sickle cell anaemia.

Knee Deformities

A knee replacement may be necessary to correct a deformity in the knee joint, such as bowing or twisting.

Risks Factors of Knee Replacement

Several risk factors can contribute to the need for knee replacement surgery. These include:

• Age: Advanced age is a common risk factor, as wear and tear on the knee joints tend to increase with time.
• Osteoarthritis: Osteoarthritis, a degenerative joint disease, is a primary contributor to the need for knee replacement. It causes the gradual breakdown of cartilage in the knee joint, leading to pain and stiffness.
• Rheumatoid arthritis: Individuals with rheumatoid arthritis, an autoimmune disorder affecting the joints, may require knee replacement surgery due to joint damage and inflammation.
• Gender: Women, particularly those over the age of 50, are more likely to undergo knee replacement surgery. Hormonal factors and anatomical differences may contribute to this increased risk.
• Obesity: Excess body weight places additional stress on the knee joints, increasing the risk of joint deterioration and the need for knee replacement.
• Trauma or injury: Previous knee injuries or trauma, such as fractures or ligament tears, can accelerate joint damage and contribute to the need for surgical intervention.
• Genetics: Genetic factors may predispose individuals to conditions such as osteoarthritis, influencing the likelihood of requiring knee replacement surgery.
• Inactive lifestyle: Lack of physical activity or an inactive lifestyle can contribute to weakened muscles and joint instability, increasing the risk of knee problems that may necessitate surgery.
• Other medical conditions: Certain medical conditions, such as avascular necrosis, gout, or bone dysplasia, can contribute to the deterioration of knee joints and elevate the risk of needing a knee replacement.
• Occupational factors: Jobs or activities that involve repetitive stress on the knees, such as heavy lifting or prolonged kneeling, may contribute to joint wear and tear, increasing the likelihood of requiring knee replacement surgery.

Preparation for Knee Replacement Surgery

• Medical assessment: The doctor will conduct a comprehensive review of the patient's personal and family medical history.
• Diagnostic tests: A series of lab, diagnostic, and imaging tests will be performed to assess the patient's fitness for the procedure.
• Medication review: The doctor may adjust current medications, either starting or discontinuing them as necessary. Patients should inform the doctor about their current medication regimen.
• Health discussion: Patients are encouraged to communicate any medications and chronic conditions they have to ensure a thorough understanding of their health status.
• Lifestyle considerations: Quitting smoking a few weeks before the procedure is advised, as it can impact the healing process.
• Physical activity: Regular exercise before the procedure is recommended to enhance post-operative healing.

Knee Replacement Procedure

• Preoperative checks: The doctor and care team will confirm the absence of allergies to medications and latex used during surgery.
• Anaesthesia administration: The anaesthetist administers anaesthesia to ensure the patient's comfort during the procedure.
• Incision and access: Precise incisions are made in and around the knee to provide access to the affected area.
• Removal of damaged parts: Injured or damaged portions of the knee are carefully removed, and the joint is meticulously prepared for the placement of prostheses.
• Prosthesis attachment: The doctor securely attaches the prostheses using specialised cement, ensuring a stable and durable fixation.
• Quality checks and adjustments: Thorough checks for movement, along with any necessary adjustments and repairs, are performed to optimise the functionality of the replaced joint.

Recovery After Knee Replacement Surgery

• Hospital stay duration: The length of the hospital stay varies based on the type of procedure performed.
• Activity restrictions: Patients are advised to refrain from lifting heavy objects, engaging in strenuous activities, or operating heavy machinery during the initial recovery period.
• Assistance arrangements: Arrangements should be made for someone to assist the patient until they regain the ability to perform daily activities independently.
• Mobility support: The doctor may recommend using a splint or a walker to aid in movement during the early stages of recovery.
• Home modifications: Home modifications may be necessary to create a more accommodating environment for the patient.
• Timeline for recovery: Full weight-bearing on the ankle and a return to daily activities may take up to 4 months, with a complete recovery extending up to a year.
• Follow-up appointments: Regular follow-up appointments are crucial for monitoring potential complications and ensuring a smooth recovery.
• Pain management: Pain relief medications will be provided to enhance the patient's comfort during the healing process.

Movement guidance: Patients will receive guidance on the gradual restoration of movement, specifying the type and range of activities they can perform at each stage of recovery.
