Patient expectations are key independent predictors of improved functional outcome and satisfaction following total joint arthroplasty.
Better understanding of this link would improve both total joint arthroplasty (TJA) care and the long-term outlook for these patients, suggests a study from Toronto Western Hospital, Toronto, Canada and Brigham and Women’s Hospital, Boston, Massachusetts.
This prospective cohort study by Nizar N Mahomed and colleagues evaluated 102 patients with primary total hip (THA) and 89 with total knee arthroplasty (TKA) via self-report questionnaires.
Patients completed the questionnaires prior to surgery and six months post-surgery. At final follow-up, researchers used the Medical Outcomes Study Short Form 36 (SF-36), the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) and a satisfaction scale to evaluate outcomes.
All of the patients, who averaged in their 60s, achieved significant improvements in their WOMAC and SF-36 scores after surgery.
Their expectations around the surgery were not linked with age, gender, index joint of surgery, marital status or race, nor were they correlated with pre-operative functional health status.
