Total Knee Replacement

Overview

In a healthy knee, the joint surfaces are covered with smooth cartilage, acting as a natural cushion to absorb shock and allow friction-free movement. Knee arthritis causes progressive cartilage loss, leading to pain, stiffness, swelling, and reduced mobility. These symptoms can significantly impact daily activities, work, and overall quality of life. 

Total knee replacement surgery (also called total knee arthroplasty) is designed to relieve pain, restore function, and improve mobility by replacing the damaged joint surfaces with a high-quality artificial implant. In selected patients where osteoarthritis affects only one compartment of the knee, a partial knee replacement may be a suitable alternative. 

What does the procedure involve?

A total knee replacement involves removing the damaged cartilage and a thin layer of underlying bone from the end of the femur (thighbone), top of the tibia (shinbone), and if required, the underside of the kneecap (patella). These surfaces are replaced with precisely shaped metal and medical-grade polyethylene (plastic) implants that replicate the natural contours and movement of the knee. 

Advanced techniques such as computer navigation or robotic-assisted knee replacement surgery may be used to ensure highly accurate bone preparation and implant positioning and alignment. 

Robotic-assisted knee replacement

While the surgeon maintains full control during the operation, the use of robotic assistance provides millimetre-accurate planning and execution, improving precision in bone preparation and implant placement. Dr Free has completed international fellowship training in robotic knee replacement surgery and will explain the process, benefits, and any potential risks during your consultation. 

Procedure preparation

Pre-operative preparation – See the pre-operative information page for general guidelines 

Day of surgery – You will be admitted on the morning of the operation. Our team will provide fasting instructions and admission details.  

Anaesthesia – Partial knee replacement can be performed under general or spinal anaesthesia. The anaesthetist will contact you before surgery to discuss your options. 

Total knee replacement recovery

Hospital stay – Most patients stay 1-3 days. 

Early mobilisation – Walking with assistance typically begins on the day of surgery 

Pain management – Medication is provided to keep you comfortable 

Wound care – A waterproof dressing will be applied. If it remains clean and intact, it can stay in place until your two-week follow-up. 

Rehab protocol

Rehabilitation after ACL surgery is essential for a successful recovery and optimal outcome. Dr Free strongly advocates a collaborative approach to ACL rehabilitation and works closely with a trusted team of physiotherapists dedicated to helping you reach the best possible results. The structured rehabilitation program includes:
