Despite the prevalence of studies relating to hip and knee arthroplasties, no Canadian studies exist in the literature regarding patients' perceptions and concerns prior to undergoing these procedures. A 32-question, 5-point Likert scale questionnaire was developed and administered to a Canadian cohort. One hundred fifty-six knee and 85 hip arthroplasty patients returned the survey. Results consistently showed complications arising from surgery, ways to reduce pain after surgery, and ability to walk properly again as the 3 top concerns for patients whether stratified by age, sex, residential status or joint replacement type. Other results discussed include resources used by patients to become better informed about joint arthroplasty, differences in Western Ontario and McMaster Universities Index of Osteoarthritis scores between groups, and significant differences in patient concerns as determined by ridit analyses.
