This study aims to assess the feasibility of conducting a pragmatic, multicentre randomized controlled trial (RCT) to test the clinical and cost-effectiveness of an informal caregiver training programme to support the recovery of people following hip fracture surgery. This will be a mixed-methods feasibility RCT, recruiting 60 patients following hip fracture surgery and their informal caregivers. Patients will be randomized to usual NHS care, versus usual NHS care plus a caregiver-patient dyad training programme (HIP HELPER). This programme will comprise of three, one-hour, one-to-one training sessions for the patient and caregiver, delivered by a nurse, physiotherapist, or occupational therapist. Training will be delivered in the hospital setting pre-patient discharge. It will include practical skills for rehabilitation such as: transfers and walking; recovery goal setting and expectations; pacing and stress management techniques; and introduction to the HIP HELPER Caregiver Workbook, which provides information on recovery, exercises, worksheets, and goal-setting plans to facilitate a ‘good’ recovery. After discharge, patients and caregivers will be supported in delivering rehabilitation through three telephone coaching sessions. Data, collected at baseline and four months post-randomization, will include: screening logs, intervention logs, fidelity checklists, quality assurance monitoring visit data, and clinical outcomes assessing quality of life, physical, emotional, adverse events, and resource use outcomes. The acceptability of the study intervention and RCT design will be explored through qualitative methods with 20 participants (patients and informal caregivers) and 12 health professionals.Aims
Methods
Urinary catheter use in the peri-operative and post-operative phase following arthroplasty may be associated with increased risk of urinary tract infection (UTI) and deep prosthetic joint infection (PJI). These can be catastrophic complications in joint arthroplasty. We performed a systematic review of the evidence on routine use of antibiotics for urinary catheter insertion and removal following arthroplasty. Electronic databases were searched using the HDAS interface. Grey literature was also searched. From 219 citations, six studies were deemed eligible for review. Due to study heterogeneity a narrative approach was adopted. Methodological quality of each study was assessed using the CASP appraisal tool. Included studies were found to have moderate to good methodological quality.Aims
Methods
Tantalum trabecular metal components are increasingly used to reconstruct major bone defects in revision arthroplasty surgery. It is known that some metals such as silver have antibacterial properties. Recent reports have raised the question as to whether Tantalum components are protective against infection in revision surgery. This is based on a retrospective, single institution review, of revision cases comparing tantalum with titanium acetabular implants, which reported a lower incidence of subsequent infection in the tantalum group. This laboratory study aimed to establish if tantalum had any intrinsic antibacterial properties against planktonic bacteria or ability to inhibit biofilm formation. Equal sized pieces of tantalum (Trabecular metal, Zimmer UK) and titanium (Trilogy, Zimmer UK) were sterilised and then incubated with a low dose inoculum of either Staphylococcus aureus or Staphylococcus epidermidis for 24 hours. After serial dilution, colony forming units were quantified on MH agar plates. To establish the ability to inhibit biofilm formation these tantalum and titanium pieces were then washed twice, sonicated and washed again to remove loosely adhered planktonic bacteria. They were then re-incubated for 24 hours prior to quantifying colony forming units. All experiments were performed in triplicateIntroduction

Previous systematic reviews have shown that patients experience low physical activity levels following total hip replacement (THR). However no previous systematic reviews have examined the changes between pre- and post-operative physical activity levels. AMED, MEDLINE, EMBASE, CENTRAL, CINHAL, openSIGLE, Introduction
Methods
Vancomycin is commonly added to acrylic bone cement during revision arthroplasty surgery. Proprietary cement preparations containing vancomycin are available but significantly more expensive. We investigated whether the antibiotic elution and mechanical strength of ‘home-made’ vancomycin containing bone cement was comparable to commercial vancomycin-impregnated cement. A total of 18 cement discs of constant size, containing either proprietary CopalG+V®; or ‘home-made’ CopalR+G® with vancomycin added by hand, were made. Each disc contained the same antibiotic quantities (0.5g gentamycin, 2g vancomycin) and was immersed in ammonium acetate buffer in a sealed container. Fluid from each container was sampled at eight time points over a two week period. The concentration of gentamicin and vancomycin in the fluid was analysed using high performance liquid chromatography mass spectrometry. The impact strength of each PMMA cement preparation was measured using a Charpy-type impact tester.Introduction
Methods
This analysis determined whether the type and level of physical activity changes during the initial 24 months post-total hip (THR) or total knee replacement (TKR) compared to pre-operative levels, and how this change compares to people without arthroplasty or osteoarthritis. Data from a prospective cohort dataset (Osteoarthritis Initiative dataset) of community-dwelling individuals who had undergone a primary THR or TKR were identified. These were compared to people who had not undergone an arthroplasty and who did not have a diagnosis of hip or knee osteoarthritis during the follow-up period (control). Data were analysed comparing between-group and within-group differences for physical activity (gardening, domestic activities, sports, employment, walking) within the first 24 months post-arthroplasty.Introduction
