In May, Mark was delighted to speak at the third annual Harrogate Partial Knee Meeting, held at the Pavilions of Harrogate.
The two-day event brought together experienced knee surgeons from across the UK and overseas to discuss current practice in partial knee replacement surgery. The programme covered patient selection, surgical techniques, imaging, rehabilitation, complications and the safe development of a partial knee replacement service.
Mark’s talk formed part of the final session, which focused on how surgeons can start or increase their use of partial knee replacement. I spoke about the surgeon profile needed to develop a successful unicompartmental knee replacement practice.
What is a partial knee replacement?
The knee is divided into three main compartments:
- The medial compartment, on the inside of the knee
- The lateral compartment, on the outside of the knee
- The patellofemoral compartment, between the kneecap and thigh bone
In some patients, arthritis is largely confined to one of these areas. When the remainder of the knee is still healthy, it may be possible to replace only the damaged part rather than performing a total knee replacement.
This is known as a partial knee replacement, or unicompartmental knee arthroplasty, often shortened to UKA.
Because the healthy cartilage, bone and ligaments are preserved, a partial knee replacement can provide a knee that feels more natural and retains good movement. However, it is not suitable for everyone. Careful examination, appropriate X-rays and good patient selection are essential.
Developing a successful partial knee replacement practice
Partial knee replacement is a technically demanding operation. Success involves more than learning the surgical steps.
Surgeons need to understand which patients are most likely to benefit, recognise when arthritis has spread too far for a partial replacement and select the appropriate procedure for the area of the knee involved.
The surgeon also needs the right training, support and commitment to reviewing their results. Regularly performing the procedure and working within an experienced multidisciplinary team can help establish consistent pathways before, during and after surgery.
Mark’s presentation considered the qualities and working practices that support this, including:
- A clear understanding of the indications for partial knee replacement
- Careful and consistent patient assessment
- Appropriate surgical training and ongoing development
- Honest discussion with patients about their options
- Close working with radiologists, anaesthetists, physiotherapists and the wider surgical team
- Regular review of outcomes and national joint replacement data
- The aim should never simply be to perform more partial knee replacements. It is to identify the patients for whom preserving the unaffected parts of the knee may offer a genuine advantage.
Why specialist educational meetings matter
The Harrogate meeting is designed to encourage practical and open discussion rather than presenting only straightforward or ideal cases.
During the event, surgeons discussed difficult decisions, complications, unsuccessful cases and the lessons that can be taken from them. The programme also included sessions on medial and lateral partial knee replacement, patellofemoral replacement, day-case surgery, imaging and technology-assisted surgery.
This type of education is important because partial knee replacement depends on sound judgement as much as technical ability. Sharing experience between surgeons helps improve how patients are assessed and treated.
Mark found the event an absolute pleasure to contribute to, alongside colleagues from the Harrogate knee team and a wider national and international faculty.
Could a partial knee replacement be suitable for you?
A partial knee replacement may be considered when:
- Arthritis is mainly limited to one part of the knee
- Knee pain is affecting walking, exercise, work or everyday life
- Non-surgical treatments are no longer providing enough relief
- The ligaments and unaffected areas of the knee remain suitable for preservation
- Some patients will be better treated with a total knee replacement, while others may not yet require surgery. The decision should be based on your symptoms, examination, imaging and personal goals rather than an X-ray alone.
Mr Mark Farndon assesses and treats patients with knee arthritis in Harrogate and Leeds. Following a detailed assessment, he can explain whether non-surgical treatment, partial knee replacement or total knee replacement may be the most appropriate option.
