Introduction: In the United Kingdom, the wait for hip or knee joint replacement surgery can be particularly long. There are conflicting research accounts whether debilitating symptoms, such as pain and the effects on physical function and quality of life deteriorate or remain the same in individuals who are on the waiting list for hip or knee joint replacement. This study was conducted to investigate the severity of pain, level of physical function and quality of life amongst adults with osteoarthritis awaiting hip or knee joint replacement.

Methods: A longitudinal study was undertaken in the North West of England during 2003–2005. A total of 105 patients listed for primary hip or knee joint replacement were recruited, interviewed at baseline, and followed-up at three, six and nine months, or until their joint replacement. Measurement tools used were a visual analogue scale (VAS), Western Ontario McMaster’s University (WOMAC) Osteoarthritis Index and the Medical Outcomes Study Short Form Health Survey (SF-36).

Results: High levels of pain and poor physical function and quality of life were experienced by patients on the waiting list for joint replacement. At the three month follow-up (n=84) changes in VAS pain scores (0.6; 95% CIs mean difference 0.3,1.0); WOMAC pain scores (1.2 (95% CIs mean difference 0.7, 1.8) and WOMAC physical function scores (4.8; 95% CIs mean difference 2.8, 6.7) were significantly worse compared to baseline. However, there were minimal changes in quality of life as measured by the SF-36 while on the waiting list.

Discussion: The often long wait for joint replacement surgery and deterioration in pain and physical function has highlighted the need for active management by health professionals while patients are on the waiting list. There needs to be a clinical reassessment of patients by health professionals while on the waiting list for joint replacement.
