What is a knee replacement?
A knee replacement is a resurfacing type of operation. A skin incision is made in the front of your knee. The kneecap and muscles are slid out of the way to access the joint surfaces.
The worn-out bone is removed and metal components are then placed on the end of the femur (thigh bone) and top of the tibia (shin bone) with a plastic cushion in between.
The back of the kneecap is sometimes also replaced with plastic if there is evidence of worn-out cartilage.
The new joint fits in amongst your own ligaments that run along the sides of your knee and utilises these ligaments for stability and to function properly
Computer navigation or robotic assistance is used to align the components accurately based on your unique anatomy. Dr Cohen aims to align the components to recreate the shape of your own knee before it wore out with arthritis. This hopefully allows your knee to be well balanced, minimising the need for ligament release, helping your new knee to work better.
The wound is closed with dissolving stitches and dressings are applied.
How long will the knee replacement last?
- For most people the knee replacement would last more than 15 years, and it may last as long as 20 or 25 years or more. There is, however, a small risk of failure at any time after knee replacement surgery for various reasons. These will be discussed in detail at your consultation.
- Dr Cohen takes certain steps to improve the chances of your joint replacement lasting a long time, including:
- choosing a prosthesis with proven results based on The Australian National Joint Replacement Registry Results
- using computer navigation/robotics and careful technique during surgery.
Knee Replacement Outcomes
Knee replacement surgery can be life-changing for those struggling with chronic knee pain and dysfunction. Our primary goal is to ensure your satisfaction following surgery, including reduced pain, improved mobility, functional independence, and an enhanced quality of life.
What is MAKO Robotic Surgery?
Dr Cohen utilises state-of-the-art MAKO robotic technology for partial and total knee replacement surgeries. MAKO technology combines CT-based planning with real-time bone and cartilage registration to provide a personalised surgical plan with precise execution and knee joint component placement. The MAKO system also provides real-time numerical assessment of the balance of the replaced knee joint, allowing for precise fine-tuning at any stage of the operation.
Alignment Philosophy - The Fingerprint Analogy
Just as no two fingerprints are the same, neither are any two knees. Dr Cohen’s alignment philosophy emphasises a personalised approach to knee replacement surgery, ensuring that implants fit and function seamlessly within your joint. By restoring your joint to its pre-arthritis state, the goal is to minimise soft tissue release and swelling after surgery, and hopefully provide a natural feel.
With this tailored approach, you can be confident that your knee replacement will be customised to match your unique knee joint anatomy.
Expected Recovery
We understand that knowing what to expect after your surgery can ease your concerns.
Below is a great graph to represent recovery from knee replacement surgery.
Here's a general timeline for recovery after knee replacement:
Weeks 1-2: Knee replacement is a major surgery. The first 2 weeks are crucial for recovery and focus on managing pain and swelling. You will start light exercises and physiotherapy to regain your motion. You should aim for 1000-1500 steps during this period, and resting the knee is essential to reducing the swelling post-surgery.
Weeks 3-6: At 3 weeks, you will turn the corner and notice a significant reduction in your pain. By now, you will hopefully only require simple pain killers like Panadol and an anti-inflammatory. Your motion will improve as will your strength, matched by a more intense physiotherapy program, which may include the introduction of the exercise bike. At this point, you should be aiming for 2000 steps per day, increasing by 500 steps per week from week 3 onwards.
Weeks 7-12: With week 7, most regular activities are reintroduced. You will be able to drive your car from week 6 and will no longer be restricted by your step count. You will begin to become accustomed to your new knee and notice a marked reduction in the swelling. Be careful, however, as if you overdo it, your knee can still swell and give you a bit of grief. If you work in a manual job, you will be cleared to return to full duties by this time.
6 Months: The majority of recovery occurs within the 6 months following surgery. By now, you will hopefully start to forget your knee has been replaced and be used to the feel of the knee. We even use the ‘Forgotten Joint Score’ to measure this effect. There is no restriction on your activity.
Following Dr Cohen’s detailed post-operative care plan will help to ensure a smooth and successful recovery.
Risks of Knee Replacement Surgery
While knee replacement surgery is generally safe and effective, it’s important to be aware of potential risks. Dr. Cohen will discuss the risks of this procedure at length during your consultation.
The risks of knee replacement include, but are not limited to:
- Infection
- Blood clots
- Fracture of the bone or damage to the ligaments
- Stiffness
- Implant-related issues
- Ongoing pain
Meticulous surgical technique, an evidence-based peri-operative protocol and by working together with Dr. Cohen and his team will help to reduce the risk of complications. You’ll also receive support and guidance on your surgical journey, ensuring peace of mind throughout your recovery.
Pain Medications
Managing pain after surgery is a top priority. Dr Cohen and his team provide a comprehensive pain management strategy, including:
Multi-Modal Pain Medications: Targeting the pain pathways at multiple levels with medications that work together to manage your post-surgery discomfort.
Custom Plans - Tailored pain management solutions based on your recovery progress and individual needs.
Bleeding and swelling Control: Tourniquet-less knee replacement, knee flexion pillows, Compression Wraps, Early Mobilisation, Regular Ice
We aim to minimise discomfort while ensuring you feel supported every step of the way.
