Abstract
Background
In the UK 70,000 knee arthroplasties are performed each year. Although outcomes from knee arthroplasties are usually excellent, they can nevertheless lead to negligence claims. The aim of this study was to establish the incidence, cost and cause of negligence claims arising from knee arthroplasties.
Method
All claims made to the NHS Litigation Authority between 2003 and 2008, where the operation was knee arthroplasty, were included in this study. Data obtained from the NHS Litigation Authority were reviewed, coded and analysed. For negligence to have occurred, patients must have suffered harm as a result of substandard care. Hence the cause of negligence claims was analysed in terms of: (1) Substandard care and (2) Harm caused.
Results
There were 326 claims over the five-year period, resulting in an incidence of 65 claims per year. Of the 326 claims, 246 have been closed with 80 remaining open. 40% of closed claims resulted in the payment of damages. The total cost of negligence claims over the period was £6.6 million. Substandard care commonly encountered in negligence claims was: surgical quality (56%), post-op care (23%), and infection control (8%). Harms commonly encountered in negligence claims were: additional/unnecessary operation (30%), pain (23%) and amputation (8%).
Conclusion
There is a significant litigation burden associated with knee arthroplasties. The unexpected prominence of additional/unnecessary operation, pain and amputation in negligence claims emphasise the need for patients to be warned about these risks.
