Expectations of total knee and hip arthroplasty patients: a multimethod study.

Recruitment & Eligibility

Status: Recruiting

Sex: Not specified

Target Recruitment: 1500

Inclusion Criteria

In order to be eligible to participate in this study, a subject must meet all of the following criteria:
- Suffering from symptoms of osteoarthritis: pain and/or stiffness during movements and when getting out of bed or a chair; and limitations during activities of daily life) (indicated by the note 'possibly osteoarthritis' in the referral)
- Having an appointment for a consultation at the Department of Orthopedics
- Receiving TKA/THA within six months after the consultation;The number of patients that is reported in D2 requires an explanation.
In this study, patients will be asked to complete questionnaires at several points in time and video recordings of the consultation between orthopedic surgeons and their TKA/THA patients will be analyzed. It is anticipated that 300 participating TKA/THA patients are required to find effects with questionnaire data, and 30 participating TKA/THA patients to find effects with the video data.
Participants need to be recruited before the consultation takes place for two reasons: (1) the first questionnaire will be completed before the consultation takes place; and (2) the patient has to give permission to videotape the consultation on forehand. However, it is not clear until the consultation has taken place whether the patient will receive TKA/THA. Therefore, all patients who meet the first and second inclusion criterion will be asked to participate. Approximately 1 out of 5 of these patients will eventually receive TKA/THA. Therefore, to reach the required sample size (300 TKA/THA patients for the questionnaire study and 30 TKA/THA patients for the video recordings), we need to recruit five times the number of participants (respectively 1500 and 150) who complete the first questionnaire and give permission to videotape the consultation. To answer the research questions, only the data of the patients who also meet the third inclusion criterion (undergoing TKA/THA) will be used. Patients who do not receive TKA/THA will receive no more questionnaires after the first one.

Exclusion Criteria

A patient who meets any of the following criteria will be excluded from participation in this study:
1. Suffering from dementia, because of expected difficulties in completing the questionnaires without assistance and taking decisions independently
2. Inadequate proficiency of the Dutch language, because of expected difficulties with completing a Dutch questionnaire and with doctor-patient communication
