British Orthopaedic Association (BOA) Guidelines recommend clinical and radiological follow-up after Total Hip Arthroplasty (THA) at 1 year, 5 years and every 5 years thereafter to detect asymptomatic failure. To evaluate the importance of routine follow-up appointments (OPAs) in detecting failing implants the presentation of patients undergoing revision THA was reviewed. 176 patients who received 183 first-time revision THAs over a seven-year period (2003-2010) were identified from an arthroplasty database. A preliminary study sampled 46 THAs in 45 patients. Retrospective chart review recorded symptoms and mode of presentation. Follow-up OPA costs were calculated to estimate savings. All patients had symptoms at the time of revision (pain 96%, decreased mobility 76%, limp 35%, stiffness 26%, night pain 24%). Route of presentation was 80% new referrals (GP 63%, in-patient 9%, A&E 4%,
Patients receiving cemented hemiarthroplasties after hip fracture have a significant risk of deep surgical site infection (SSI). Standard UK practice to minimize the risk of SSI includes the use of antibiotic-loaded bone cement with no consensus regarding type, dose, or antibiotic content of the cement. This is the protocol for a randomized clinical trial to investigate the clinical and cost-effectiveness of high dose dual antibiotic-loaded cement in comparison to low dose single antibiotic-loaded cement in patients 60 years and over receiving a cemented hemiarthroplasty for an intracapsular hip fracture. The WHiTE 8 Copal Or Palacos Antibiotic Loaded bone cement trial (WHiTE 8 COPAL) is a multicentre, multi-surgeon, parallel, two-arm, randomized clinical trial. The pragmatic study will be embedded in the World Hip Trauma Evaluation (WHiTE) (ISRCTN 63982700). Participants, including those that lack capacity, will be allocated on a 1:1 basis stratified by recruitment centre to either a low dose single antibiotic-loaded bone cement or a high dose dual antibiotic-loaded bone cement. The primary analysis will compare the differences in deep SSI rate as defined by the Centers for Disease Control and Prevention within 90 days of surgery via medical record review and patient self-reported questionnaires. Secondary outcomes include UK Core Outcome Set for hip fractures, complications, rate of antibiotic prescription, resistance patterns of deep SSI, and resource use (more specifically, cost-effectiveness) up to four months post-randomization. A minimum of 4,920 patients will be recruited to obtain 90% power to detect an absolute difference of 1.5% in the rate of deep SSI at 90 days for the expected 3% deep SSI rate in the control group.Aims
