Individualized knee replacements: a personalised approach to joint health
While traditional knee replacements have been highly successful, advances in medical technology now allow surgeons to tailor knee replacements to the unique anatomy of each patient.
In this article, consultant orthopaedic surgeon Mr Jonathan Quayle explores an individualized approach to knee replacements, how it differs from standard procedures, and what patients can expect before, during, and after knee surgery.
Traditional vs individualised alignment
Historically, knee surgeons positioned joint replacements in ways intended to compensate for the perceived limitations of implants. This often involved altering a patient’s individual anatomical alignment. With advances in manufacturing techniques and technological adjuncts, it is now possible to replicate a patient’s original anatomy without the need for bespoke implants.
Individualised alignment with conventional implants
Rather than using bespoke implants or image-guided surgery, Mr Jonathan Quayle achieves a personalised outcome by applying a calipered kinematic alignment technique. This method uses standard knee implants, but they are positioned with great precision to restore the knee’s natural anatomy and movement.
While this technique can be performed with robotic or navigation assistance, Mr Quayle delivers it using conventional surgical instruments, ensuring that each knee is aligned as closely as possible to the patient’s original joint structure.
Why an individualised alignment makes a difference
Traditional knee replacements can sometimes feel unnatural or restrict certain movements because they don’t respect a patient’s natural joint orientation. Applying an Individualized alignment strategy restores your knee’s original kinematics, meaning the way your knee moves after surgery feels closer to how it did before arthritis or injury.
What to expect during surgery
The surgical procedure is similar to traditional knee replacement surgery, with the key difference being the implant positioning is matched to your knee rather than the other way around. The operation usually takes 1 to 2 hours and is performed under general or spinal anaesthesia.
Recovery and rehabilitation
Recovery can vary, but most patients are encouraged to begin movement exercises soon after knee surgery. Physiotherapy is crucial to regain strength, flexibility, and function. Because the implant is tailored to your knee, many patients report a more natural feel and smoother recovery.
Potential benefits of an individualized approach
- Better fit and comfort: reduced risk of implant loosening or discomfort.
- Improved functionality: more natural knee movement during walking, climbing, and daily activities.
- Potential for longer implant life: accurate alignment may reduce wear over time.
- Personalised care: surgery and recovery plans are tailored specifically to you.
Is it right for you?
Individualised knee alignment is particularly beneficial for patients with high activity levels and can even be used in patients with more severe deformities and unusual anatomy. However, not every patient is a candidate, and the decision should be made with a specialist orthopaedic surgeon after a thorough assessment.
If you are struggling with knee pain and are considering knee surgery, consulting Mr Quayle about individualized knee replacements may provide the best outcome for your mobility and long-term joint health.
