Kinematically Aligned Total Knee Replacement Surgery
Knee Replacement Procedures: Kinematically Aligned Total Knee Replacement Surgery
Kinematically aligned total knee replacement surgery is an advanced surgical approach designed to restore the natural alignment and movement of the knee joint. This procedure uses cutting-edge technology, such as Sphere, KA, and MyKnee systems, to personalise the alignment of the knee replacement to match the patient’s unique anatomy. By closely replicating the knee’s natural motion, this technique may help improve comfort, function, and satisfaction compared to traditional total knee replacement methods.

What Is Kinematically Aligned Total Knee Replacement Surgery?
Kinematically aligned knee replacement is a surgical technique that prioritises restoring the knee joint’s natural alignment and movement. This approach uses advanced technologies like Sphere implants, MyKnee personalised cutting guides, and efficiency-focused tools to customise the procedure to each patient’s anatomy. Unlike traditional mechanical alignment, which focuses on standardised positioning, kinematic alignment aims to replicate the natural angles and motion of the patient’s knee for a more personalised outcome.
When Is Kinematically Aligned Total Knee Replacement Recommended?
Kinematically aligned knee replacement may be recommended for patients who:
- Have Advanced Osteoarthritis: Severe wear and tear of the knee joint causing chronic pain, stiffness, and limited mobility.
- Have Joint Deformities: Misalignment or structural issues affecting the knee’s natural motion.
- Seek a Personalised Solution: Patients who may benefit from a customised approach to knee replacement.
- Have Not Found Relief: Patients whose symptoms persist despite non-surgical treatments, such as physiotherapy, medications, or injections.
Preparation For Kinematically Aligned Total Knee Replacement Surgery
Proper preparation ensures the best possible outcomes:
- Pre-Surgical Assessment: Dr Scott Tulloch will perform a thorough evaluation of your knee, including imaging tests such as X-rays, CT scans, or MRIs, to plan the personalised alignment.
- Pre-Surgery Instructions: You may be advised to stop certain medications, follow fasting guidelines, and prepare for post-surgical care, such as arranging assistive devices or modifying your home.
- Lifestyle Adjustments: Improving overall health through weight management, smoking cessation, and pre-surgery exercises may help optimise recovery and reduce risks.
What Happens During The Surgery?
- Surgical Technique: Kinematic alignment uses advanced tools like MyKnee cutting guides and imaging technology to create a personalised surgical plan tailored to your unique anatomy.
- Anaesthesia: The procedure is performed under general anaesthesia or regional anaesthesia (e.g., spinal anaesthesia).
- Procedure Steps:
- Damaged cartilage and bone are removed from the knee joint.
- Personalised implants, such as Sphere components, are positioned to closely match the natural alignment of your knee.
- The new joint is aligned and stabilised for optimal function.
- Duration: Surgery generally takes 1-2 hours.
Understanding The Risks
As with any surgical procedure, kinematically aligned total knee replacement carries potential risks. Dr Scott Tulloch will discuss these with you and outline steps to minimise them. Risks may include:
- Infection at the surgical site
- Blood clots in the legs or lungs
- Stiffness or limited range of motion in the knee
- Implant loosening or wear over time
- Rare complications, such as nerve or blood vessel damage
What To Expect After Surgery
- Hospital Stay: Most patients stay in hospital for 2-3 days for monitoring and initial recovery.
- Pain Management: Medications and cold therapy may be used to manage post-surgical pain and swelling.
- Assistive Devices: Crutches or a walker may be required to support mobility during the initial recovery phase.
- Discharge Instructions: You will receive detailed guidance on wound care, activity restrictions, and recognising signs of complications.
Rehabilitation And Recovery
- Recovery Timeline: Initial recovery may take 4-6 weeks, with full recovery typically achieved within 3-6 months.
- Physiotherapy: A structured physiotherapy program is essential to rebuild strength, improve flexibility, and restore knee function.
- Activity Restrictions: High-impact activities may need to be avoided during recovery to protect the new joint and ensure proper healing.
Long-term Outcomes
Kinematically aligned total knee replacement may provide significant relief from pain and improved joint function for many patients. The personalised approach aims to create a more natural feeling in the knee, potentially improving satisfaction and long-term outcomes.
The implants used in this procedure, such as Sphere components, are designed to last 15-20 years or more, depending on factors such as activity levels and overall health. Regular follow-up appointments with Dr Scott Tulloch are recommended to monitor the condition of the knee and maintain optimal results.
Maintaining an active, healthy lifestyle, including regular low-impact exercise, can help preserve the benefits of the procedure and enhance long-term knee function.
