Aim. Repeat revision surgery of total hip or knee replacement may lead to massive bone loss of the femur. If these defects exceed a critical amount a stable fixation of a proximal or distal femur replacement may not be possible. In these extraordinary cases a total femur replacement (TFR) may be used as an option for limb salvage. In this retrospective study we examined complications, revision free survival (RFS), amputation free survival (AFS) and risk factors for decreased RFS and AFS following a TRF in cases of revision arthroplasty with a special focus on periprosthetic joint infection (PJI). Method. We included all implantations of a TFR in
Arthrofibrosis is a less common complication following anterior cruciate ligament (ACL) reconstruction and there are concerns that undergoing early surgery may be associated with arthrofibrosis. The aim of this study was to identify the patient and surgical risk factors for arthrofibrosis following primary ACL reconstruction. Primary ACL reconstructions prospectively recorded in the New Zealand ACL Registry between April 2014 and December 2019 were analyzed. The Accident Compensation Corporation (ACC) database was used to identify patients who underwent a subsequent
Aim. To investigate the incidence and time-trend in
Aim. Prosthetic joint infections (PJI) and fracture related infections (FRI) are the most challenging complications in orthopaedic surgery. An interdisciplinary approach is mandatory not only to correctly diagnose and treat major musculoskeletal infections but also to address the comorbidities and impairments these patients are not rarely suffering from. Since, little data exists on cardiac complications following PJI and FRI
Aim. Periprosthetic joint infection (PJI) is a devastating complication in revision total hip arthroplasty (THA). As preoperative diagnosis can be difficult, some patients who undergo planned aseptic
Recent advances in arthroplasty for the hip and the knee have motivated modern foot and ankle research to perfect the implant and technique for the optimal total ankle replacement. Unlike in the hip where different approaches can be done with similar implants, the approach of a total ankle is intimately associated to the prosthetic design. The anterior and lateral approaches have pros and cons regarding their respective soft tissue complications, osteotomy necessity, orientation of the bone cut and gutter visualization. While both have been studied independently, very few reports have compared both in the same setting. This study retrospectively looked at the difference in
This study aims to determine the incidence of surgical site infection leading to
Aims. Metal-on-metal total hip replacements (MoM THRs) are frequently revised. However, there is a paucity of data on clinical outcomes following
Aim. In two-stage replacements for septic loosening, some studies have suggested that associate bacterial colonization of spacers had a worse result in relation to the control of the infection and a higher rate of complications after the implantation of the definitive prosthesis. The aim of our study was to determine the
Introduction. PSI technology have proved helpful in difficult primary Total Knee Replacement. However applying it to revision was impossible due to multiple factor. To Start with the landmark We usually destroy it. There is an extensive damage at the bone at the epiphysis, the implant prevent an accurate visualization and debridement usually change the surface of the bone as well which make applying the psi dyed impossible, we are proposing a new way of using psi in revision where we don't depend on the all masses adjusted in primary. However we depend on the metaphysical area of the bone. Material & method. We have reviewed 56 MRI & CT scans for cases posted for revision and showed clearly that in spite of the extensive bony destruction and metal presence the MRI / CT scan we were able to visualize well the metaphysical area in the intramedullary canal in both tibial and femoral we have established a special external guide that depends on the outside surface of the metaphysis of the femur. We have tried this model on six plastic bone and showed that this external guide can give the accurate details that the surgeon is looking for in a
C-reactive protein (CRP) level is used at our tertiary paediatric hospital in the diagnosis, management, and discharge evaluation of paediatric septic arthritis patients. The purpose of this study was to evaluate the efficacy of a discharge criterion of CRP less than 2 mg/dL for patients with septic arthritis in preventing
Despite long-standing dogma, a clear relationship between the timing of surgical irrigation and the development of subsequent deep infection has not been established in the literature. Traditionally, irrigation of an open fracture has been recommended within six-hours of injury based on animal studies from the 1970s, however the clinical basis for this remains unclear. Using data from a multi-centre randomized controlled trial of 2,447 open fracture patients, the primary objective of this secondary analysis is to determine if a relationship exists between timing of wound irrigation (within six hours of injury versus beyond six hours) and subsequent
A significant portion of ankle arthroplasty and ankle arthrodesis procedures performed in British Columbia are funded by the public medical services plan (MSP). However, some patients are treated privately through self-pay or by the workers compensation board (WCB), with the latter two groups being more likely to receive treatment sooner. The potential effect of payer on patient-reported outcomes and
Internal fixation remains the treatment of choice for non-displaced femoral neck fractures in elderly patients, whereas, arthroplasty is preferred for displaced fracture patterns. Given technological advancements in implant design and excellent long-term outcomes, arthroplasty may provide improved outcomes for the treatment of non-displaced femoral neck fractures. The aim of our study was to conduct a systematic review of the orthopaedic literature (1) to investigate the outcomes of internal fixation for the treatment of non-displaced and minimally displaced femoral neck fractures in elderly patients and (2) to compare the outcomes of patients treated with internal fixation to arthroplasty in this patient population. Relevant articles were identified using PubMed, Embase, and CENTRAL databases. Manuscripts were included only if they contained (1) patients 60 years or older with (2) nondisplaced or minimally displaced (Garden I or II) femoral neck fractures (3) treated with internal fixation or arthroplasty or (4) separately reported outcomes in this patient population. The primary outcome was
Osseointegration has emerged as a promising alternative to rehabilitating with a traditional socket mounted prosthesis. Advantages have been reported to include improved functional mobility, better osseoperception, improved comfort, reduced pain, better biomechanical alignment and better gait, which all lead to a less restricted lifestyle and significantly improved quality of life. A major concern of the Osseointegrated approach lies in the risk of infections occurring from the permanent transcutaneous opening often referred to as the stoma. Several systematic reviews have indicated that the occurrence of minor infections can be quite common, serious complications are reported to be rare. In addition to commonly anticipated complications including fractures, surgical debridements or revisions, we have identified several significant events in which a patient may require to be readmitted and go through additional surgery. The objective of this study is to examine the rate of occurrence and reports on the best management practices of serious complications across a multi-centre review of more than 1000 osseointegration surgeries. A detailed analysis has been performed on all osseointegration surgeries performed by the Osseointegration Group of Australia and it's affiliates between since 2010. The majority of surgeries took place in Australia, the United States, the Middle East as well as in Europe. All events leading to a re-admission and subsequent re-operation have been identified through hospital operation records and pooled together for meta-analysis. Events identified include: revision of implants, periprosthetic fracture fixation, surgical debridement due to infections, neurectomies and soft- tissue refashioning.Introduction

Our aim was to highlight that there is a sub-group of patients with disabling symptoms after leg lengthening at primary hip replacement who benefit from
Lower limb amputation is associated with significant morbidity and mortality. Reflecting the predominance of vascular or diabetic disease as a cause for lower limb amputation, much of the available literature excludes lower limb amputation secondary to trauma in the reporting of complication rates. This paucity in the literature represents a research gap in describing the incidence of complications in lower limb amputation due to trauma, which we aim to address. Retrospective analysis of a prospectively collected database of all traumatic lower limb amputations secondary to trauma from a regional multidisciplinary amputee service at Queen Mary's Hospital. Electronic patient records and paper notes were consulted for evidence of re-operation, infection (superficial or deep), phantom limb pain and neuroma. 222 patients were screened and 108 included in the data analysis.Introduction

Introduction. Complication and revision rates have shown to be high for all metal-on-metal (MoM) bearings, especially for the ASR Hip System (ASR hip resurfacing arthroplasty (HRA) and ASR XL total hip arthroplasty (THA)). This prompted the global recall of the ASR Hip System in 2010. Many studies have previously explored the association between female gender and
