“…In the modern culture of evidence based practice and especially after recent high-profile medical device malfunctions, most notably with metal-on-metal bearing arthroplasty, orthopaedic surgeons should be cautious about novel treatments and have been urged to demand highquality evidence to legitimise product claims [11,12]. In this study we evaluated the validity of claims made in print journal advertisements published internationally, and the influence on the manufacturers' target audience: practising orthopaedic surgeons.…”

Purpose Advertisements are commonplace in orthopaedic journals and may influence the readership with claims of clinical and scientific fact. Since the last assessment of the claims made in orthopaedic print advertisements ten years ago, there have been legislative changes and media scrutiny which have shaped this practice. The purpose of this study is to re-evaluate these claims. Methods Fifty claims from 50 advertisements were chosen randomly from six highly respected peer-reviewed orthopaedic journals (published July-December 2011). The evidence supporting each claim was assessed and validated by three orthopaedic surgeons. The assessors, blinded to product and company, rated the evidence and answered the following questions: Does the evidence as presented support the claim made in the advertisement and what is the quality of that evidence? Is the claim supported by enough evidence to influence your own clinical practice? Results Twenty-eight claims cited evidence from published literature, four from public presentations, 11 from manufacturer "data held on file" and seven had no supporting evidence. Only 12 claims were considered to have high-quality evidence and only 11 were considered well supported. A strong correlation was seen between the quality of evidence and strength of support (Spearman r =0.945, p <0.0001). The average ICC between the assessors' ratings was strong (r =0.85) giving validity to the results. Conclusion Orthopaedic surgeons must remain sceptical about the claims made in print advertisements. High-quality evidence is required by orthopaedic surgeons to influence clinical practice and this evidence should be sought by manufacturers wishing to market a successful product.

“…There have also been high-profile episodes of medical device malfunction, including most notably metal-on-metal bearing arthroplasty [10]. These episodes have made orthopaedic surgeons more sceptical about new advances and they have been urged to scrutinise all available evidence before changing their clinical practice [11,12].…”

“…There now exists good evidence to demonstrate excellent short-term functional results and lower dislocation rates compared to standard THA. However, the analysis of national joint registries [3,5] revealed higher revision rates for hip resurfacing arthroplasty devices, notably metal-on-metal (MoM) bearings in women, compared with THA devices. To date, we have few data to guide our choices regarding the right technical choices (such as implant selection) or to inform our prognostic estimates when considering the revision of a failed hip resurfacing arthroplasty.…”
