Are you prepared to be asked clinical case studies?

Have strong, up-to-date, MSK clinical knowledge 

Consider looking at NICE guidelines for common conditions you may encounter in primary care

Be aware of multi-systems that can masquerade as MSK pains e.g. red flags, rheumatological conditions, vascular pathologies etc.

Think about your management plan for the patient e.g. self management, further investigations, onward referrals, MDT discussion etc.
