Thousands of NHS Joint Replacements at Risk Amid Bone Cement Shortage
A critical shortage of essential bone cement could lead to the cancellation of thousands of vital joint replacement operations across the National Health Service (NHS) in Australia. Health authorities have issued a stark warning to clinical and orthopaedic leads nationwide, flagging potential manufacturing delays of at least two months.
The issue stems from a packaging fault affecting bone cement products supplied by Heraeus Medical, a key supplier to the NHS. This unforeseen problem has temporarily halted production at their primary manufacturing site, casting a shadow over product availability for an extended period.
Understanding the Crucial Role of Bone Cement
Bone cement plays an indispensable role in orthopaedic surgery, acting much like a high-strength grout. It’s used to securely affix artificial joints to the patient’s bone, a process most commonly seen in hip and knee replacement procedures. The cement is specifically designed to harden rapidly, creating a stable and robust bond that ensures the new implant remains firmly in place.

Beyond standard fixation cements, some affected products incorporate antibiotics. These specialised cements are crucial in high-risk infection scenarios or during revision surgeries, where a previous joint replacement has failed or become infected. The antibiotics are released locally into the surrounding tissues, aiding in infection control. Certain formulations are specifically designed for managing infections during complex revision procedures. In these instances, the cement can be used to permanently secure a new implant after an infection has been cleared, or it can form temporary “spacers.” These spacers help maintain the joint’s space and stability while delivering potent doses of antibiotics before a new implant is eventually inserted.
The Impact on Patients and Waiting Lists
The potential disruption comes at a time when NHS waiting lists for orthopaedic procedures are already at an all-time high. Parliamentary data from February 2025 revealed that over 31,323 patients were awaiting hip replacements, with a median waiting time of approximately 24.7 weeks. Similarly, 49,500 patients were on the waiting list for knee replacements, facing an average wait of 28.7 weeks.
This two-month delay in bone cement supply could therefore impact thousands of individuals who have already endured lengthy waits for essential treatment. To put the scale into perspective, NHS England performed approximately 120,000 hip replacement procedures and 96,000 knee replacements during the 2023/24 period.
NHS Response and Mitigation Efforts
The NHS is treating this situation with utmost seriousness. An incident team has been established, and close collaboration with Heraeus Medical is underway to address the crisis. The NHS Supply Chain department has communicated the issue to its partners, stating, “We are assessing the potential supply impact and will provide further updates as more information becomes available.”
The supply chain notice further elaborated: “We are coordinating with the Department of Health and Social Care and NHS England to manage the situation nationally. NHS Supply Chain is engaging with the impacted supplier Heraeus Medical and alternative suppliers to identify potential support options.”
Heraeus Medical UK Ltd holds a significant contract with the NHS under the Total Orthopaedic Solutions 3 (TOS3) framework, valued between £1.8 billion and £2 billion over four years.
Expert and Patient Advocacy Concerns
Deborah Alsina, Chief Executive of Arthritis UK, expressed deep concern over the developing situation. “This is a crushing blow for those individuals who have finally made it to the front of the orthopaedic surgery queue after a long time waiting,” she stated. “We trust the Department for Health and Social Care will work hard to address the supply issues given the impact on those waiting in pain whose lives are left on hold.”
Alsina highlighted the significant personal toll on individuals living with arthritis and the broader challenge for the government in meeting ambitious waiting list reduction targets. “As this news breaks, we urge hospitals to communicate quickly with those affected to avoid additional worry and uncertainty,” she added. Arthritis UK is also offering support through its helpline and online community for those concerned about the delays.
The current treatment delays compound an already challenging situation, with over 7.37 million treatments – involving 6.23 million patients – currently in the backlog for procedures like hip replacements. This includes more than 190,000 individuals who have been waiting for at least a year, often in considerable pain.
Reassurance on Existing Procedures
Heraeus has provided reassurance that patients who have already undergone operations using the existing bone cement products are not affected by this issue. The company explained that a critical machine failure at their main production site during a process improvement project has led to the inability to release pouch bone cements manufactured on that specific machine.

“We plan to re-start production as quickly as possible, but with the production cycle time to get products to the market, this will result in a supply shortage of pouch cements for at least the next two months,” Heraeus stated. “Products already in the market are not affected and comply with our packaging quality criteria.”
An NHS spokesperson confirmed that immediate guidance is being issued to hospitals to ensure trauma and urgent care can continue safely. The focus is on enabling the use of alternative suppliers where feasible and prioritising orthopaedic waiting lists based on patient need in the coming weeks. While existing stock in hospitals remains unaffected, the NHS is working collaboratively with the government and professional bodies to ensure safe and effective care is maintained throughout the resolution of this supply issue, aiming to minimise delays for less urgent patient care.
