Robotic arm surgery for joint replacement_environmental data

Dear Network Colleagues, 

I am doing some research into environmental impact differences (amongst other outcomes) between manual and robotic arm orthopaedic surgery (partial/total knee and total hip).

I would greatly value any papers, reports, case studies, presentations etc that anyone is able to .share with me? I will of course look into the resources on here and repositories online.

Many thanks

Kind regards

Mel
