Patients’ perspectives of outcomes after total knee and total hip arthroplasty: a nominal group study

Abstract

Abstract Background While total joint replacements (TJR) are frequently performed, there is little qualitative research to define the outcomes most important to patients. Methods Patients who had received total hip (THR) or total knee replacements (TKR) participated in 8 nominal groups to answer the question “What result/results matter the most to a patient undergoing/having a knee or hip replacement?” Total 270 votes were allocated. Results Eight nominal groups were performed with 45 patients, 6 groups with mean age (71.1 ± 9.3), and 2 with 9 younger patients (mean age 36.8 ± 7.4). All had TJR between 2016 and 2018; overall, 40% were male, 15.6% were Black, and 75% were performed for osteoarthritis. While all groups ranked the same top 3 outcomes, responses varied with age: 1) relief of pain (46% vs. 35% in the young groups); 2) improved function including mobility (29% vs. 18% in the young groups); 3) restored quality of life (13% vs 33% of votes in the younger group). Conclusion Relief of pain and restoration of function, and improved quality of life are the 3 outcomes ranked highest by patients, confirming their inclusion in TJR clinical trials.
