Determining Appropriateness of Total Joint Arthroplasty for Hip and Knee Osteoarthritis: A Patient-Centred Conceptual Model.

Our proposed conceptual model reconceptualises the appropriateness of TJA to be more patient-centred. Hence, this approach has the potential to be a more inclusive approach and ensure patients undergoing TJA are eligible, ready to proceed, and achieve what matters most to them. Future research is needed to test and validate the model.
