Strategies to Manage Poorer Outcomes After Hip or Knee Arthroplasty: A Narrative Review of Current Understanding, Unanswered Questions, and Future Directions

Abstract

PurposeAlthough hip or knee arthroplasty is generally a successful intervention, it is documented that 15%–30% of patients undergoing arthroplasty report suboptimal outcomes. This narrative review aims to provide an overview of the key findings concerning the management of poorer outcomes after hip or knee arthroplasty.MethodA comprehensive search of articles was conducted up to November 2023 across three electronic databases. Only studies written in English were included, with no limitations applied regarding study design and time.ResultEfficiently addressing poorer outcomes after arthroplasty necessitates a thorough exploration of appropriate methods for assessing recovery following hip or knee arthroplasty, ensuring accurate identification of patients at risk or experiencing poorer recovery. When selecting appropriate outcome measure tools, various factors should be taken into consideration, including understanding patients' priorities throughout the recovery process, assessing psychometric properties of outcome measure tools at different time points after arthroplasty, understanding how to combine/reconcile provider‐assessed and patient‐reported outcome measures, and determining the appropriate methods to interpret outcome measure scores. However, further research in these areas is warranted. In addition, the identification of key modifiable factors affecting outcomes and the development of interventions to manage these factors are needed.ConclusionThere is growing attention paid to delivering interventions for patients at risk or not optimally recovering following hip or knee arthroplasty. To achieve this, it is essential to identify the most appropriate outcome measure tools, factors associated with poorer recovery and management of these factors.
