Aim. The aim of this study is to evaluate the value of inflammatory parameters normalization and/or increased time between stages necessary in predicting healing and preventing infection recurrence. Method. We retrospectively studied all cases of total hip and knee arthroplasty that underwent revision for infection in our institution between 2011 and 2014. We revised the clinical and laboratory information from 55 patients (27 hips: 28 knees) with a mean age of 68 years. The average values before the first stage were 88.6 mm/h (15–134) and 59.1 mg/L (2–279) for the erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP) serum respectively. In 10 cases (18.2%) it was not possible to perform the second stage. Moreover, in the other 45 cases of re- arthroplasty, the mean follow-up was 32 months (1 year). Results. Among the 45 cases in which the two stages were completed, only 3(6.7%) had recurrence of infection. No significant differences between the two groups regarding the absolute values of ESR and/or CRP before the second stage or variation between the first and second stage of revision were seen. Interestingly, in the group of cases where there was recurrence of infection, the average values of CPR and ESR before the second stage were even lower: 6.0 vs. 11.8 mg/L and 19.3 vs. 28.7 mm/h respectively. Analysing the temporal influence on the recurrence rate, we find that the 17 cases in which the second stage was performed in less than 90 days, there were no recurrences. The three recurrences occurred in the group of patients with an interval > 90 days (3/28 – 11%). Conclusions. Knowing when to perform the second stage safely is one of the most difficult decision in two-stage procedures. Tradition mandates
An instrumented blood culture system automatically flags when growth within the culture medium has been detected (‘work in progress’), and subsequently when the organism has been identified. We explore using this data to switch patients to oral therapy within 72 hours post-surgery, reducing costs and improving antimicrobial stewardship. This retrospective review focused on clinically significant culture-positive bone and joint infections over a 5-month period in 2022. Two cohorts were defined as either having positive intraoperative microbiology at <72 hours or at ≥72 hours.Aim
Method
Most acetabular defects can be treated with a cementless acetabular cup and screw fixation. However, larger defects with segmental bone loss and discontinuity often require reconstruction with augments, a cup-cage, or triflange component – which is a custom-made implant that has iliac, ischial, and pubic flanges to fit the outer table of the pelvis. The iliac flange fits on the ilium extending above the acetabulum. The ischial and pubic flanges are smaller than the iliac flange and usually permit screw fixation into the ischium and pubis. The custom triflange is designed based on a pre-operative CT scan of the pelvis with metal artifact reduction, which is used to generate a three-dimensional image of the pelvis and triflange component. The design of the triflange involves both the manufacturing engineer and surgeon to determine the most appropriate overall implant shape, screw fixation pattern, and cup location and orientation. A plastic model of the pelvis, and triflange implant can be made in addition to the triflange component to be implanted, in order to assist the surgeon during planning and placement of the final implant in the operating room. A wide surgical exposure is needed including identification of the sciatic nerve. Proximal dissection of the abductors above the sciatic notch to position the iliac flange can risk denervation of the abductor mechanism. Blood loss during this procedure can be excessive. Implant survivorship of 88 to 100% at 53-month follow-up has been reported. However, in a series of 19 patients with Paprosky type 3 defects, only 65% were considered successful. The custom triflange also tends to lateralise the hip center which may adversely affect hip mechanics. The use of a triflange component is indicated in cases with massive bone loss or discontinuity in which other reconstructive options are not considered suitable.
Although the introduction of ultraporous metals in the forms of acetabular components and augments has substantially improved the orthopaedic surgeon's ability to reconstruct severely compromised acetabuli, there remain some revision THAs that are beyond the scope of cups, augments, and cages. In situations involving catastrophic bone loss, allograft-prosthetic composites or custom acetabular components may be considered. Custom components offer the potential advantages of immediate, rigid fixation with a superior fit individualised to each patient. These custom triflange components require a pre-operative CT scan with three-dimensional (3-D) reconstruction using rapid prototyping technology, which has evolved substantially during the past decade. The surgeon can fine-tune exact component positioning, determine location and length of screws, modify the fixation surface with, for example, the addition of hydroxyapatite, and dictate which screws will be locked to enhance fixation. The general indications for using custom triflange components include: (1) failed prior salvage reconstruction with cage or porous metal construct augments, (2) large contained defects with possible discontinuity, (3) known pelvic discontinuity, and (4) complex multiply surgically treated hips with insufficient bone stock to reconstruct using other means. The general indications for using custom triflange components include: (1) failed prior salvage reconstruction with cage or porous metal construct augments, (2) large contained defects with possible discontinuity, (3) known pelvic discontinuity, and (4) complex multiply surgically treated hips with insufficient bone stock to reconstruct using other means. We previously reported on our center's experience with 23 patients (24 hips) treated with custom triflange components with minimum 2-year follow-up. This method of reconstruction was used in a cohort of patients with Paprosky Type 3B acetabular defects, which represented 3% (30 of 955) of the acetabular revisions we performed during the study period of 2003 to 2012. At a mean follow-up of 4.8 years (range, 2.3–9 years) there were 4 subsequent surgical interventions: 2 failures secondary to sepsis, and 1 stem revision and 1 open reduction internal fixation for periprosthetic femoral fracture. There were 2 minor complications managed nonoperatively, but all of the components were noted to be well-fixed with no obvious migration or loosening observed on the most recent radiographs. Harris hip scores improved from a mean of 42 (SD ± 16) before surgery to 65 (SD ± 18) at latest follow-up (p<0.001). More recently, we participated in a multi-center study of 95 patients treated with reconstruction using custom triflange components who had a mean follow-up of 3.5 years. Pelvic defects included Paprosky Type 2C, 3A, 3B and pelvic discontinuity. Concomitant femoral revision was performed in 21 hips. Implants used a mean of 12 screws with 3 locking screws. Twenty of 95 patients (21%) experienced at least one complication, including 6% dislocation, 6% infection, and 2% femoral-related issues. Implants were ultimately removed in 11% of hips. One hip was revised for possible component loosening. Survivorship with aseptic loosening as the endpoint was 99%, Custom acetabular triflange components represent yet another tool in the reconstructive surgeon's armamentarium. These devices can be helpful in situations of catastrophic bone loss, achieving reliable fixation. Clinical results are inferior to both primary THA and more routine revision THA. Patients and surgeons should be aware of the increased complications associated with these complex hip revisions.
Acetabular defects often result from osteolysis with or without component loosening. The goals of acetabular reconstruction in the face of significant rim or column deficiencies are to create a stable acetabular construct, which will facilitate acetabular component biologic fixation and long-term stability. Four reconstructive techniques have emerged to treat these defects: 1) Large allografts, 2) Cup / Cage constructs, 3) Metallic augments and uncemented hemispherical cups, and 4) Triflange custom implants. While all of these techniques have demonstrated success, we have elected to pursue triflange implants to improve fixation on host bone, allow modular liner options, facilitate enhanced fixation surfaces, match patient complex geometries, opportunity to utilise locking screws, and possibly reduce surgical operative time. Furthermore, screw paths and lengths can be planned pre-operatively along with custom pelvic model generation which makes surgical exposure and reconstructive more understandable. Multiple studies have shown excellent survivorship in series of the most challenging acetabular reconstructions.
The Two Week Waiting Time Standard, which requires that patients with suspected cancer referred by general practitioners should be seen within 2 weeks, was introduced in 2000. We reviewed the performance of this standard with regards to proportion of patients seen and tumour detection rates. We reviewed all the referrals sent under the ‘two week’ rule from January 2004 to December 2005, to our bone and soft tissue sarcoma service. These referrals were evaluated for: Whether or not the referral met established referral guidelines for bone and soft tissue tumours The proportion of patients seen within two weeks The proportion of patients referred under the guidelines that had malignant tumours. This was compared with the total number of referrals to the unit and their tumour detection rates. A total of 40 patients were referred under the ‘two week’ rule. 95% of these were seen within two weeks of referral. Of the 40 patients, three patients had soft tissue metastasis from a primary tumour elsewhere, and six had primary malignant soft tissue tumours. 13 had a benign bone/ soft tissue tumour. 18 (45%) patients had a non neoplastic pathology (6 Muscle tear/ herniation; 4 ganglion/bursa; 2 lumps that disappeared) During the same period a total of 507 patients were referred by other routes.Introduction

Hip and knee joint arthroplasty
The progressive painful and disabling predicament of patients with severe osteoarthritis awaiting a total hip or knee arthroplasty (THA/TKA) results in a decline in muscle mass, strength and function also known as Sarcopenia. We conducted a cross-sectional, prospective study of patients on the waiting-list for a THA/TKA in the South Australian public healthcare system and compared the findings to healthy participants and patients newly referred from their general practitioners. Participants with a history of joint replacements, pacemakers and cancers were excluded from this study. Outcomes of this study included (i) sarcopenia screening (SARC-F ≥4); (ii) sarcopenia, defined as low muscle strength (hand grip strength M<27kg; F<16kg), low muscle quality (skeletal muscle index M<27%, F<22.1%) and low physical performance (short physical performance battery ≤8). Additional outcomes include descriptions of the recruitment feasibility, randomisation and suitability of the assessment tools. 29 healthy controls were recruited; following screening, 83% (24/29) met the inclusion criteria and 75% (18/24) were assessed. 42 newly referred patients were recruited; following screening, 67% (30/45) met the inclusion criteria and 63% (19/30) were assessed. 68

Aims. Elective orthopaedic services have had to adapt to significant system-wide pressures since the emergence of COVID-19 in December 2019. Length of stay is often recognized as a key marker of quality of care in patients undergoing arthroplasty. Expeditious discharge is key in establishing early rehabilitation and in reducing infection risk, both procedure-related and from COVID-19. The primary aim was to determine the effects of the COVID-19 pandemic length of stay following hip and knee arthroplasty at a high-volume, elective orthopaedic centre. Methods. A retrospective cohort study was performed. Patients undergoing primary or revision hip or knee arthroplasty over a six-month period, from 1 July to 31 December 2020, were compared to the same period in 2019 before the COVID-19 pandemic.
