Abstract
Background and purpose: Considering dissatisfaction rates of around 10% after total hip arthroplasty (THA), this study aimed to investigate the role of pain catastrophising (PC) on functional outcomes, pain, and quality of life following THA in a large prospective study. PC is the tendency to focus on and exaggerate painful stimuli combined with a decreased ability to deal with pain.
Patients and methods: A prospective comparative study was performed with 531 patients undergoing primary unilateral THA between 2019 and 2020. Patients were considered PC with a preoperative score ⩾30 on the PC Scale, resulting in 57 (11%) PC-patients. Patient-reported outcome measures (PROMs) were collected preoperatively, at 3 months, 1 year, and 2 years postoperatively and consisted of Hip disability and Osteoarthritis Outcome Score-Physical Function (HOOS-PS), Oxford Hip Score (OHS), pain (NRS), and quality of life (EQ-5D), including minimal clinical important differences (MCIDs) and patient acceptable symptom state (PASS), as well as length of stay and aseptic revisions.
Results: PC-patients reported inferior preoperative scores on all PROMs and had longer hospital stay (p = 0.02). Although PC-patients had more improvement in all scores and a higher proportion generally reached MCID, they still reported lower OHS, more pain, and lower EQ-5D at 2-year follow-up (all p < 0.03), and fewer PC-patients reached PASS for OHS and EQ-5D at final follow-up. No difference in aseptic revisions was seen (p = 0.95).
Conclusions: PC-patients had worse preoperative subjective function and more pain. Although they showed more improvement than non-PC patients at all outcomes, less patients reached PASS for OHS and EQ-5D at 2-year follow-up.
期刊介绍:
HIP International is the official journal of the European Hip Society. It is the only international, peer-reviewed, bi-monthly journal dedicated to diseases of the hip. HIP International considers contributions relating to hip surgery, traumatology of the hip, prosthetic surgery, biomechanics, and basic sciences relating to the hip. HIP International invites reviews from leading specialists with the aim of informing its readers of current evidence-based best practice.
The journal also publishes supplements containing proceedings of symposia, special meetings or articles of special educational merit.
HIP International is divided into six independent sections led by editors of the highest scientific merit. These sections are:
• Biomaterials
• Biomechanics
• Conservative Hip Surgery
• Paediatrics
• Primary and Revision Hip Arthroplasty
• Traumatology
