We invite Professor Cobb back to discuss the latest in surgical education with particular focus on arthroplasty surgery. Questions include:

- How has hip arthroplasty practice changed globally in the last 20 years?

- How this compares to UK practice and explanations behind the difference?

- Which practice is more effective and which is more cost-effective?

- Is there a large learning curve to direct anterior approach and if so how can it be mitigated?

- How does cognitive task analysis, virtual reality and team simulation address this?
