Introduction

Hospitals within the NHS are currently grappling with a shortage of bone cement, a crucial material used in many orthopaedic surgeries. Bone cement is especially important in knee replacement operations, providing stability and support for patients who have suffered trauma—such as neck of femur fractures—or those undergoing surgery due to cancer-related bone issues. In response to these recent supply problems, leading bodies like the British Orthopaedic Association (BOA), the British Association for Surgery of the Knee (BASK), and other specialist groups have issued guidance to help hospitals decide how best to prioritise knee surgery cases. This article explains how hospitals are following BOA guidance to manage limited bone cement supplies and explores innovative solutions like the use of uncemented implants that some clinics have successfully introduced.

Why Bone Cement Matters and What the Shortage Means

Bone cement is much more than just glue—it forms the structural bond between the artificial knee implant and the patient’s bone, helping to secure the implant firmly in place. For many patients, especially those who have suffered trauma such as hip fractures or have cancer affecting their bones, bone cement is essential for providing a stable and lasting repair.

Unfortunately, the UK is currently facing a shortage of this vital material, causing delays and potential disruption to elective orthopaedic surgeries across NHS hospitals. This affects not just waiting lists but also patient recovery and outcomes. Recognising this challenge, the BOA and related specialist societies have provided clear guidance to help clinical teams navigate this shortage sensibly. A key part of this guidance is prioritising cases that most urgently require cemented implants—such as revisions due to infection—to ensure those in greatest need can still receive timely treatment.

How BOA and Specialist Societies Guide Prioritisation

The BOA’s recommendations offer a practical framework for hospitals needing to allocate scarce bone cement. Priorities are set based on the clinical urgency of each case: trauma patients and those requiring revision surgeries to address infections are at the top of the list. In making these decisions, doctors also consider patient factors like overall health and risk of complications.

The guidance from the BASK knee society complements this approach by offering focussed advice on managing knee surgery cases during the shortage. Both organisations emphasise the importance of collaboration across specialties—surgeons, anaesthetists, physiotherapists—to ensure decisions balance patient safety with effective resource use. These expert-led recommendations are further supported by NHS elective orthopaedics guidelines, which seek to create a consistent nationwide response to the cement shortage.

Innovative Solutions: Using Uncemented Implants Where Possible

One way hospitals are adapting to the bone cement shortage is by using uncemented knee implants for those patients whose conditions allow it. Unlike cemented implants, uncemented prosthetics depend on the natural growth of bone onto the implant surface, eliminating the need for cement altogether.

This approach has been successfully adopted by clinics such as MSK Doctors, which have transitioned selected patients to uncemented implants while maintaining excellent clinical results. By reserving cement for cases where it is absolutely essential, these innovations help maintain patient care standards despite supply constraints and reduce surgical delays.

Leadership and Support in a Challenging Time

Navigating this complex situation requires strong clinical leadership. Professor Paul Lee, a leading expert in orthopaedics and musculoskeletal rehabilitation, exemplifies this skill through his clinical work and his ambassadorial role with the Royal College of Surgeons of Edinburgh. His expertise helps ensure that best practices are maintained during these challenging times.

At MSK Doctors, this leadership is paired with a commitment to providing a professional and supportive environment for patients undergoing knee surgery. The clinic places great value on following specialist society guidance closely, ensuring patient-centred care that responds proactively to shortages while maintaining high standards of treatment.

Conclusion

Bone cement remains a cornerstone in many knee replacement surgeries, especially for trauma and complex revision cases. The current shortage means hospitals must prioritise carefully and look to new approaches to sustain service quality. Thanks to clear, evidence-based guidance from the BOA, BASK, and other expert groups, NHS hospitals can manage these challenges thoughtfully and effectively.

With experienced clinicians like Professor Paul Lee and dedicated teams at clinics such as MSK Doctors, patients can be reassured that their knee care continues to be delivered safely and effectively, even when resources are limited. This balanced approach ensures that, despite temporary shortages, the standard of orthopaedic care remains high and patient outcomes continue to improve.
