We randomised 120 patients who were undergoing either primary total hip or knee arthroplasty to receive either ferrous sulphate or a placebo for three weeks after surgery. The level of haemoglobin and absolute reticulocyte count were measured at one and five days, and three and six weeks after operation. Ninety-nine patients (ferrous sulphate 50, placebo 49) completed the study. The two groups differed only in the treatment administered.

Recovery of level of haemoglobin was similar at five days and three weeks and returned to 85% of the pre-operative level, irrespective of the treatment group. A small, albeit greater recovery in the level of haemoglobin was identified at six weeks in the ferrous sulphate group in both men (ferrous sulphate 5%, placebo 1.5%) and women (ferrous sulphate 6%, placebo 3%). The clinical significance of this is questionable and may be outweighed by the high incidence of reported side effects of oral iron and the cost of the medication. Administration of iron supplements after elective total hip or total knee arthroplasty does not appear to be worthwhile.

Introduction: With an ever-increasing elderly population the rise in primary total hip replacement is inevitable. This translates into a comparative rise in revision hip surgery. We performed an observational study to determine current revision hip surgical practices in one UK region.

Methods: We utilized a regional hip register (Trent Arthroplasty Audit Group (TAAG)) to review current revision hip surgical practice in our region. 136 surgeons in 21 different hospitals, covering a population of 6.2 million, contribute to the register. We analysed completed data forms to produce the following results.

Results: 875 revision THRs performed between 2000 and 2002 were identified. 54% were female, with a mean age of 70 (range 26–97). 45 different femoral stems requiring revision were identified. Reasons for revision were aseptic loosening of both components (23%), cup alone (24%), stem alone (17%), infection (14%), recurrent dislocation (10%), periprosthetic fracture (5%) and acetabular erosion (3%). Over 25 different femoral stems and over 30 different acetabular components were utilised by surgeons. In 70% of cases the femoral and acetabular components were made by different manufacturers. Bone graft was used in approximately 50% of cases. 90% of centres contributing to TAAG perform revision hip surgery. 24% of all revision THRs were performed by surgeons performing 5 or less per year. Only 40% of revision THRs were performed by ‘revision surgeons’ performing > 20 per year.

Conclusions: It is evident the majority of centres, both teaching and DGH, in our region regularly perform revision hip surgery, with up to a quarter performed by non-revision specialists. With increasing numbers of prostheses available, high numbers of component mismatch use, and the inevitable increase in future need for revision hip surgery, is the occasional revision surgeon compromising patient care? Will this have future medico-legal consequences?
