Evaluation of the effectiveness of hip and knee implant models used in Catalonia: a protocol for a prospective registry-based study.

The study presented in this protocol will allow us to identify the hip and knee prosthesis models whose results might be better or worse than expected. This information could have a potential impact at the patient, orthopaedic surgeon, healthcare manager, decision-making and industry levels, both in the short term and in the medium and long term.
