The Medicines and Healthcare products Regulatory Agency (MHRA) has issued an important update regarding the risks associated with Profemur cobalt chrome modular neck hip replacements. A recent investigation has revealed unexpected complications, including increased device fractures and wear-related effects, which may significantly raise the likelihood of revision surgeries. This development is highly relevant for clinical, quality, and regulatory teams working with orthopedic devices.

What changed?
On September 30, 2025, the MHRA released findings from its investigation into Profemur modular neck hip implants that contain cobalt chrome. The investigation highlighted higher-than-expected risks of corrosion and wear within these components, which can lead to both fractures and the need for revision surgeries. This is a deviation from the anticipated safety outcomes associated with these devices.
Manufacturers and clinical teams are being urged to assess the impact of this information on their practices and take steps to ensure patient safety while reviewing their current inventories of affected devices.
Clinical findings and implications
The core findings of the MHRA’s investigation raise concerns about the long-term performance of Profemur cobalt chrome modular neck hip replacements:
- Device wear and corrosion: Increased wear and corrosion have been observed in the cobalt chrome components, potentially causing inflammation and adverse tissue reactions.
- Fracture risks: Higher-than-anticipated occurrences of device fracture have been documented, necessitating revision surgeries in affected patients.
- Metal-wear effects: The wear-related release of cobalt particles may pose a systemic risk to patients and complicate their post-operative outcomes.
These findings emphasize the importance of ongoing monitoring and proactive intervention strategies for healthcare providers managing patients implanted with these devices.
Who is affected?
The MHRA has identified key stakeholders who should carefully review their practices in light of this announcement:
- Healthcare professionals: Surgeons, orthopedic teams, and device management departments must assess whether their patients have been implanted with these devices, monitor performance, and educate affected individuals about potential risks.
- Medical device manufacturers: Manufacturers of Profemur modular neck hip replacements must examine their production processes and provide updated safety information to the public.
- Regulatory and quality teams: These teams should verify compliance with safety standards and assess the applicability of reporting systems for adverse events.
Patients and caregivers should consult their healthcare providers if concerned about their implanted devices.
FAQ
- 1. What are Profemur modular neck hip replacements?
These are orthopedic implants used in hip surgeries to restore mobility and reduce pain. They feature modular neck components for improved fitting. - 2. What risks are associated with cobalt chrome components?
Cobalt chrome modular necks may experience wear and corrosion over time, which can lead to fracture or adverse tissue reactions. - 3. Should healthcare providers replace these devices immediately?
Not necessarily. Monitoring patient outcomes, conducting individual risk assessments, and consulting with orthopedic experts are recommended before taking such measures.
Quick recap and actions
The MHRA has uncovered heightened risks associated with Profemur cobalt chrome modular neck hip implants, including wear, corrosion, fractures, and the need for revision surgeries. Clinical, quality, and regulatory teams are strongly advised to assess their current protocols, inventory, and affected patient populations. Immediate attention to monitoring and reporting systems is critical to mitigating patient risk.
