BackgroundIndividuals with hip or knee osteoarthritis (OA) are referred to orthopaedic surgeons if considered by their GP as potential candidates for total joint replacement (TJR). It is not clear which patients end up having this surgery.AimThe aim of the study was to investigate symptom variation in individuals with OA newly referred by GPs to an orthopaedic surgeon for consideration for TJR, and to determine the predictors of having this procedure.Design And SettingA longitudinal study of patients at a regional orthopaedic centre with follow-up at 3, 6, and 12 months by postal questionnaire.MethodGP referrals of patients with OA to orthopaedic surgeons were consecutively sampled. Of the 431 eligible patients, 257 (59.6%) were recruited. Validated measurement tools were used to measure pain, physical functioning, severity of OA, and health-related quality of life.ResultsOver half the participants were in constant pain, taking pain medication more than once per day. Only 67 of 134 (50%) hip and 40 of 123 (33%) knee patients had a TJR within 12 months. Those who had a replacement had been diagnosed with OAfora shorter time, reported more frequent pain, were more likely to use a walking stick, and had worse pain, stiffness, and physical functioning.ConclusionMany individuals considered for TJR ultimately may not have surgery, and more effective strategies of management need to be developed between primary and secondary care to achieve better outcomes and to improve quality of care.
