Addressing Patients' Expectations of Total Knee Arthroplasty in a Randomized Trial

Addressing Patients' Expectations of Total Knee Arthroplasty: Developing and Testing an Educational Intervention in a Randomized Trial

The goals of this study are to develop and test an educational intervention to address patients' expectations of long-term outcomes of total knee arthroplasty.

The first goal of this study is to develop an educational intervention to address patients' expectations of long-term outcomes of total knee arthroplasty. The intervention will be structured according to the expectations listed in the Hospital for Special Surgery Total Knee Replacement Expectations Survey. The second goal is to test the intervention in a randomized trial. An additional goal is to compare patients' self-reported knee symptoms with radiographic findings.

The primary outcome is the within-patient change between pre and post program scores measured by the Hospital for Special Surgery Total Knee Replacement Expectations Survey.

The secondary outcome is to compare patient-reported symptoms with radiographic ratings of disease activity.

The secondary outcome is to determine if expectations after the class coincide more closely with orthopedic surgeons expectations

Inclusion Criteria: Patients will be eligible for this study if they are 40 years of age or older and are scheduled for primary total knee arthroplasty at the Hospital for Special Surgery. Exclusion Criteria: Patients will be excluded from this study for the following reasons: if they are not fluent in English; if they are not going to attend the preoperative knee replacement class; if they are unable to complete the surveys; if they refuse to participate.
