I was excited to discover MEDtube during my online research for video content in ortopedics. Such project was missing. Professional medical education requires more open and innovative approach. I will use the platform in my teaching activities and publish own content. I look forward to joint projects with MEDtube and promise my personal support in Hong Kong and continental China. Good luck!
