Abstract
BackgroundTo investigate prospectively the patient-relevant outcome 7 years after total hip replacement (THR) for osteoarthritis (OA).Methods219 consecutive patients (120 women) with primary OA, mean age 71 (range 50-92) were assigned for THR. They were examined preoperatively, at 3, 6, 12 months, and at 4, 5 and 7 years postoperatively with the self-administered questionnaires SF-36 and WOMAC. Supplementary questions regarding postoperative complications, general co-morbidity, social circumstances and patient satisfaction were asked at the three last follow-ups. A reference group, 117 subjects (67 women), mean age 72 (range 52-92) without hip complaints were recruited from the community and investigated at the same times.Results151/170 (89%) of the patients and 65/74 (88%) of the reference group participated at the 7 year follow-up. The best postoperative result was reported one year postoperatively. At the 7 year follow up there was a significant difference between the patients and controls in SF-36 physical function (PF) and role physical (RP) but not of WOMAC function. There was no difference in frequency of co-morbid conditions between those operated and the reference group, but those operated were in greater need of walking aid (46% vs. 8% p < 0.0001) and reported more regional and widespread pain (68% vs. 53% p < 0.05).ConclusionThis study shows that in an unselected cohort the patients experience a similar health-related quality of life as a reference group of a similar age and sex structure 7 years after THR except for general physical function where the patients score worse.
Highlights
To investigate prospectively the patient-relevant outcome 7 years after total hip replacement (THR) for osteoarthritis (OA)
In a review in Lancet 2007 [1]THR was identified as the operation of the century since THR has revolutionized the management of elderly patients with osteoarthritis (OA) with very good long term results in terms of prosthetic survival and cost-effectiveness
In patients suffering from severe osteoarthritis (OA) total joint replacement is known to be the most effective treatment [2]and it offers the patient pain relief as well as improved physical function [3,4]
Summary
To investigate prospectively the patient-relevant outcome 7 years after total hip replacement (THR) for osteoarthritis (OA). Total hip replacement (THR) is one of the most common interventions in orthopedic surgery. In a review in Lancet 2007 [1]THR was identified as the operation of the century since THR has revolutionized the management of elderly patients with osteoarthritis (OA) with very good long term results in terms of prosthetic survival and cost-effectiveness. In patients suffering from severe osteoarthritis (OA) total joint replacement is known to be the most effective treatment [2]and it offers the patient pain relief as well as improved physical function [3,4]. The main indication for THR is severe pain [5]. Patients’ expectations after THR have changed [6]
