Aims

This study evaluates the association between consultant and hospital volume and the risk of re-revision and 90-day mortality following first-time revision of primary hip arthroplasty for aseptic loosening.

Aims

In metal-on-metal (MoM) hip arthroplasties and resurfacings, mechanically induced corrosion can lead to elevated serum metal ions, a local inflammatory response, and formation of pseudotumours, ultimately requiring revision. The size and diametral clearance of anatomical (ADM) and modular (MDM) dual-mobility polyethylene bearings match those of Birmingham hip MoM components. If the acetabular component is satisfactorily positioned, well integrated into the bone, and has no surface damage, this presents the opportunity for revision with exchange of the metal head for ADM/MDM polyethylene bearings without removal of the acetabular component.

Aims

We compared the risks of re-revision and mortality between two-stage revision surgery and single-stage revision surgery among patients with infected primary knee arthroplasty.

Aims

Despite multiple trials and case series on hip hemiarthroplasty designs, guidance is still lacking on which implant to use. One particularly deficient area is long-term outcomes. We present over 1,000 consecutive cemented Thompson’s hemiarthroplasties over a ten-year period, recording all accessible patient and implant outcomes.

Aims

Surgical site infection (SSI) is a common complication of surgery with an incidence of about 1% in the United Kingdom. Sutures can lead to the development of a SSI, as micro-organisms can colonize the suture as it is implanted. Triclosan-coated sutures, being antimicrobical, were developed to reduce the rate of SSI. Our aim was to assess whether triclosan-coated sutures cause a reduction in SSIs following arthroplasty of the hip and knee.

Aims

This study aimed to compare the change in health-related quality of life of patients receiving a traditional cemented monoblock Thompson hemiarthroplasty compared with a modern cemented modular polished-taper stemmed hemiarthroplasty for displaced intracapsular hip fractures.

Objectives

The objective of this study was to assess all evidence comparing the Thompson monoblock hemiarthroplasty with modular unipolar implants for patients requiring hemiarthroplasty of the hip with respect to mortality and complications.

Objectives

We have increased the dose of tranexamic acid (TXA) in our enhanced total joint recovery protocol at our institution from 15 mg/kg to 30 mg/kg (maximum 2.5 g) as a single, intravenous (IV) dose. We report the clinical effect of this dosage change.

Aims

A fracture of the hip is the most common serious orthopaedic injury, and surgical site infection (SSI) is one of the most significant complications, resulting in increased mortality, prolonged hospital stay and often the need for further surgery. Our aim was to determine whether high dose dual antibiotic impregnated bone cement decreases the rate of infection.

Background

Approximately half of all hip fractures are displaced intracapsular fractures. The standard treatment for these fractures is either hemiarthroplasty or total hip arthroplasty. The recent National Institute for Health and Care Excellence (NICE) guidance on hip fracture management recommends the use of ‘proven’ cemented stem arthroplasty with an Orthopaedic Device Evaluation Panel (ODEP) rating of at least 3B (97% survival at three years). The Thompsons prosthesis is currently lacking an ODEP rating despite over 50 years of clinical use, likely due to the paucity of implant survival data. Nationally, adherence to these guidelines is varied as there is debate as to which prosthesis optimises patient outcomes.

Objectives

We wanted to investigate regional variations in the organisms reported to be causing peri-prosthetic infections and to report on prophylaxis regimens currently in use across England.

The National Institute for Health and Clinical Excellence (NICE) has thus far relied on historical data and predominantly industry-sponsored trials to provide evidence for venous thromboembolic (VTE) prophylaxis in joint replacement patients. We argue that the NICE guidelines may be reliant on assumptions that are in need of revision. Following the publication of large scale, independent observational studies showing little difference between low-molecular-weight heparins and aspirin, and recent changes to the guidance provided by other international bodies, should NICE reconsider their recommendations?

Objectives

To review the current best surgical practice and detail a multi-disciplinary approach that could further reduce joint replacement infection.

Introduction: Payment by results was introduced into the NHS in an effort to finance Trusts fairly and reward good performance. Tariffs for a single patient episode are derived from diagnosis and procedure codes, comorbidities, patient age, and length of stay. Poor data collection can result in a lower tariff with subsequent under billing of the Primary Care Trust (PCT). In addition, an individual surgeon’s performance in future comparison league tables will rely on the accuracy of this data. Methods of documentation and data collection vary in different units. We evaluated the methods and the resulting tariffs in 2 units in the Northern Deanery.

Methods: Case notes were examined for 20 consecutive orthopaedic patients discharged from unit A, and 20 from unit B. The case mix in the two groups was similar. A correct tariff based on case notes was compared with the actual tariff used to bill the PCT for each patient. The coding department derived actual tariffs from data in electronic discharge summaries created by ward based junior medical staff in unit A. Accurately completed typed case notes were available to coders in unit B.

Results: Only 3 of the 20 tariffs (15%) were correct for unit A patients. This represented a total financial loss to the trust of £14892 (25% of total revenue). In unit B, 19 of 20 (95%) tariffs were correct. An error in the coding for one procedure resulted in a higher tariff being assigned to a patient (total gain of £486, < 1%).

Discussion: Orthopaedic departments create large Trust revenue. Accurate documentation and information transfer for coding is essential for payment by results to function correctly. Trusts which fail to do this will be financially penalised and surgeon league tables may not adequately reflect individual case complexity. We recommend all Trusts use the model established in unit B.

We wished to determine the most accurate and reliable technique for insertion of tibial prostheses, with tibial resection guided by either intramedullary (IM) or extramedullary (EM) alignment jigs.

135 consecutive AGC cemented total knee replacements in 126 patients in a single unit were performed by, or directly supervised by, four consultant surgeons. Ethical approval and patient consent was obtained. Intramedullary alignment was used for the femoral cuts and patients were randomised at the time of operation to have either IM or EM guides for resection of the proximal tibia, cut with a zero degree posterior slope in both. The protocol only entered patients into the trial if their knees were suitable for use with both IM and EM tibial alignment although, in the event, no patients were excluded. Long leg radiographs (standing hip to ankle) were taken by a standardised method three months after the surgery. A blinded assessor, unaware of the alignment method used, evaluated acceptable films and measured tibial component alignment. The proportion of tibial prostheses aligned within two degrees of 90 was the endpoint of the study.

Of the 135 knees 100 suitable x-rays were assessed. Correct tibial alignment was more likely in the IM group (85%) than the EM group (65%), p=0. 019. Though mean alignment was similar, variation (standard deviation) was less in the IM group (2. 0 vv 2. 2).

In the AGC knee, intramedullary alignment guides are superior to extramedullary guides for alignment of the tibial prosthesis. We recommend the routine use of intramedullary tibial alignment.
