When using a staged approach to eradicate chronic infection after total hip replacement, systemic delivery of antibiotics after the first stage is often employed for an extended period of typically six weeks together with the use of an in situ antibiotic-eluting polymethylmethacrylate interval spacer. We report our multi-surgeon experience of 43 consecutive patients (44 hips) who received systemic vancomycin for two weeks in combination with a vancomycin- and gentamicin-eluting spacer system in the course of a two-stage revision procedure for deep infection with a median follow-up of 49 months (25 to 83). The antibiotic-eluting
The number of revision arthroplasties being performed in the elderly is expected to rise, including revision for infection. The primary aim of this study was to measure the treatment success rate for octogenarians undergoing revision total hip arthroplasty (THA) for periprosthetic joint infection (PJI) compared to a younger cohort. Secondary outcomes were complications and mortality. Patients undergoing one- or two-stage revision of a primary THA for PJI between January 2008 and January 2021 were identified. Age, sex, BMI, American Society of Anesthesiologists grade, Charlson Comorbidity Index (CCI), McPherson systemic host grade, and causative organism were collated for all patients. PJI was classified as ‘confirmed’, ‘likely’, or ‘unlikely’ according to the 2021 European Bone and Joint Infection Society criteria. Primary outcomes were complications, reoperation, re-revision, and successful treatment of PJI. A total of 37 patients aged 80 years or older and 120 patients aged under 80 years were identified. The octogenarian group had a significantly lower BMI and significantly higher CCI and McPherson systemic host grades compared to the younger cohort.Aims
Methods
Femoral cement-in-cement revision is a well described technique to reduce morbidity and complications in hip revision surgery. Traditional techniques for septic revision of hip arthroplasty necessitate removal of all bone cement from the femur. In our two centres, we have been using a cement-in-cement technique, leaving the distal femoral bone cement in selected patients for septic hip revision surgery, both for single and the first of two-stage revision procedures. A prerequisite for adoption of this technique is that the surgeon considers the cement mantle to be intimately fixed to bone without an intervening membrane between cement and host bone. We aim to report our experience for this technique. We have analyzed patients undergoing this cement-in-cement technique for femoral revision in infection, and present a consecutive series of 89 patients. Follow-up was undertaken at a mean of 56.5 months (24.0 to 134.7) for the surviving cases.Aims
Methods
The duration of systemic antibiotic treatment following first-stage revision surgery for periprosthetic joint infection (PJI) after total hip arthroplasty (THA) is contentious. Our philosophy is to perform an aggressive debridement, and to use a high local concentration of targeted antibiotics in cement beads and systemic prophylactic antibiotics alone. The aim of this study was to assess the success of this philosophy in the management of PJI of the hip using our two-stage protocol. The study involved a retrospective review of our prospectively collected database from which we identified all patients who underwent an intended two-stage revision for PJI of the hip. All patients had a diagnosis of PJI according to the major criteria of the Musculoskeletal Infection Society (MSIS) 2013, a minimum five-year follow-up, and were assessed using the MSIS working group outcome-reporting tool. The outcomes were grouped into ‘successful’ or ‘unsuccessful’.Aims
Methods
We aimed to report the mid- to long-term rates of septic and aseptic failure after two-stage revision surgery for periprosthetic joint infection (PJI) following total hip arthroplasty (THA). We retrospectively reviewed 96 cases which met the Musculoskeletal Infection Society criteria for PJI. The mean follow-up was 90 months (SD 32). Septic failure was assessed using a Delphi-based consensus definition. Any further surgery undertaken for aseptic mechanical causes was considered as aseptic failure. The cumulative incidence with competing risk analysis was used to predict the risk of septic failure. A regression model was used to evaluate factors associated with septic failure. The cumulative incidence of aseptic failure was also analyzed.Aims

Recurrent infection following two-stage revision total hip arthroplasty
(THA) for prosthetic joint infection (PJI) is a devastating complication.
The purpose of this study was to report the survival of repeat two-stage
revision hip arthroplasty, describe complications, and identify
risk factors for failure. We retrospectively identified 19 hips (19 patients) that had
undergone repeat two-stage revision THA for infection between 2000
to 2013. There were seven female patients (37%) and the mean age
was 60 years (30 to 85). Survival free from revision was assessed
via Kaplan–Meier analysis. The patients were classified according
to the Musculoskeletal Infection Society (MSIS) system, and risk
factors for failure were identified. Mean follow-up was four years
(2 to 11).Aims
Patients and Methods
Two-stage exchange remains the gold standard
for treatment of peri-prosthetic joint infection after total hip replacement
(THR). In the first stage, all components and associated cement
if present are removed, an aggressive debridement is undertaken
including a complete synovectomy, and an antibiotic-loaded cement
spacer is put in place. Patients are then treated with six weeks
of parenteral antibiotics, followed by an ‘antibiotic free period’
to help ensure the infection has been eradicated. If the clinical
evaluation and serum inflammatory markers suggest the infection
has resolved, then the second stage can be completed, which involves
removal of the cement spacer, repeat debridement, and placement
of a new THR. Cite this article:
We conducted a prospective study of a delta ceramic total hip
arthroplasty (THA) to determine the rate of ceramic fracture, to
characterise post-operative noise, and to evaluate the mid-term
results and survivorship. Between March 2009 and March 2011, 274 patients (310 hips) underwent
cementless THA using a delta ceramic femoral head and liner. At
each follow-up, clinical and radiological outcomes were recorded.
A Kaplan-Meier analysis was undertaken to estimate survival.Aims
Patients and Methods
We report the outcome at ten to 15 years of two-stage revision for hip infection in 99 patients using the Prostalac articulated hip spacer system. All the patients were contacted to determine their current functional and infection status using the Oxford-12, Short form-12, and Western Ontario and McMaster University Osteoarthritis Index questionnaires. A total of 11 of the 99 patients had a further infection, of whom seven responded to repeat surgery with no further sequelae. The mean interval between the stages was five months (1 to 36). We were able to review 48 living patients, with a mean age of 72 years (46 to 86), 34 (71%) of whom provided health-related quality-of-life outcome scores. The mean follow-up was 12 years (10 to 15). The long-term success rate was 89% and with additional surgery this rose to 96%. The mean global Western Ontario and McMaster University Osteoarthritis Index score was 80.6 ( Two-stage revision for hip infection using a Prostalac interim spacer offers a predictable and lasting solution for patients with this difficult problem.
Based on the first implementation of mixing antibiotics
into bone cement in the 1970s, the Endo-Klinik has used one stage
exchange for prosthetic joint infection (PJI) in over 85% of cases.
Looking carefully at current literature and guidelines for PJI treatment,
there is no clear evidence that a two stage procedure has a higher
success rate than a one-stage approach. A cemented one-stage exchange
potentially offers certain advantages, mainly based on the need
for only one operative procedure, reduced antibiotics and hospitalisation time.
In order to fulfill a one-stage approach, there are obligatory pre-,
peri- and post-operative details that need to be meticulously respected,
and are described in detail. Essential pre-operative diagnostic
testing is based on the joint aspiration with an exact identification
of any bacteria. The presence of a positive bacterial culture and
respective antibiogram are essential, to specify the antibiotics
to be loaded to the bone cement, which allows a high local antibiotic
elution directly at the surgical side. A specific antibiotic treatment
plan is generated by a microbiologist. The surgical success relies
on the complete removal of all pre-existing hardware, including
cement and restrictors and an aggressive and complete debridement
of any infected soft tissues and bone material. Post-operative systemic
antibiotic administration is usually completed after only ten to
14 days. Cite this article:
We present a series of 114 patients with microbiologically-proven chronically-infected total hip replacement, treated between 1991 and 2004 by a two-stage exchange procedure with antibiotic-loaded cement, but without the use of a prolonged course of antibiotic therapy. The mean follow-up for all patients was 74 months (2 to 175) with all surviving patients having a minimum follow-up of two years. Infection was successfully eradicated in 100 patients (87.7%), a rate which is similar to that reported by others, but where prolonged adjuvant antibiotic therapy has been used. Using the technique described, a prolonged course of systemic antibiotics does not appear to be essential and the high cost of the administration of antibiotics can be avoided.
