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

Abstract

IntroductionTotal joint arthroplasty (TJA) for osteoarthritis is one of several treatment options with benefits and harms that patients value differently. However, the process for determining TJA appropriateness does not sufficiently acknowledge patient perspectives. The aim of this paper is to propose an evidence‐informed patient‐centred conceptual model for elective TJA appropriateness for hip and knee osteoarthritis.MethodsOur interprofessional team developed a conceptual model for determining the appropriateness of adults considering elective TJA. The model was informed by a review of the evidence, a qualitative study we conducted with adults who underwent TJA for osteoarthritis to determine barriers and facilitators to the use of appropriateness criteria, and the research and clinical experience of team members.ResultsAppropriateness is providing health services (e.g., TJA) with net benefits to the right patient at the right time. The proposed Patient‐centred Elective TJA Appropriateness Conceptual Model involves three key steps. First, assess adults with osteoarthritis to determine eligibility for TJA. Second, acknowledge the patient's informed preferences including their expectations and goals. Third, explore and support their mental and physical readiness for TJA. Given that osteoarthritis is a chronic condition, these steps can be revisited over time with patients.Discussion and ConclusionOur 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.
