Research summary
Total knee replacement, or total knee arthroplasty, is a surgical procedure which aims to relieve chronic knee pain and improve function. While the majority of patients who have a knee replacement procedure experience good outcomes, up to 20% of patients experience poor outcomes. This subset of patients experience persistent pain, functional difficulties and are dissatisfied following surgery. Previous research indicates that these findings cannot be entirely explained by biomedical factors. A number of studies have demonstrated the influence of psychological factors on outcomes of knee replacement surgery. The current study aims to examine the specific psychological factors which are involved in recovery from a knee replacement. The following psychological factors will be examined: anxiety, depression, stress, personality traits, quality of life, general ability to cope with problems and how they cope with pain. Demographic information will also be collected. It is anticipated that the findings will enhance understanding of the specific psychological factors involved in recovery from a knee replacement. It is also anticipated that the findings will inform the development of a preoperative measure to screen for patients at risk of poor outcomes and the development of subsequent interventions for this population.
Participants will be patients aged 18 years and older who attend the Primary Joint Unit (PJU) in Musgrave Park Hospital, Belfast for a total knee replacement. Prior to attending the preoperative clinic, participants will be posted a cover letter introducing the study and a participant information sheet (PIS). The PJU will then telephone potential participants to establish their interest in the study. Interested patients will be sent the consent form and questionnaire pack along with a stamped addressed envelope. Questionnaires will also be posted at six weeks, 12 weeks and one year following surgery. Clinical information about the knee replacement, other health conditions, complications and the amount of contact with the health service will also be gathered from medical notes and ongoing audit data.
