INTRODUCTION: Cultures of deep synovial biopsies remain an important tool in diagnosing periprosthetic joint infection, a devastating complication following total hip arthroplasty (THA). Recent reports of unexpected positive intraoperative cultures in aseptic revision arthroplasty, however, challenge the validity and interpretation of these cultures. The aim of this study was to evaluate the contamination risk of synovial biopsy cultures collected intraoperatively during primary THA of healthy subjects...

BACKGROUND: In the context of an increase number of primary and revision total hip and total knee arthroplasty performed yearly, an increased risk of complication is expected. Prosthetic joint infection (PJI) remains the most common and feared arthroplasty complication. Ralstonia pickettii is a Gram-negative bacterium, that has also been identified in biofilms. It remains an extremely rare cause of PJI. There is no report of an identification of R. pickettii on an extracted spacer loaded with antibiotic...

BACKGROUND: Total wrist arthroplasty (TWA) has been described as traditionally being performed with fixation in the radius and carpus with cement. The TWA implant used in our series has been associated with promising results in studies with up to 6 years followup; however, studies evaluating survivorship, pain, and function with this implant are limited. QUESTION/PURPOSE: (1) To report ROM and pain scores after wrist reconstruction with cementless fourth-generation TWA at a mean followup of 9 years (range, 4...

BACKGROUND: Giant cell tumor (GCT) of bone is a benign, though locally aggressive tumor, classically described as an eccentric lytic lesion, often with cortical expansion and destruction. It typically involves the metaphysis or epiphysis of long bones in skeletally mature patients, with a slight female predominance. The incidence in the small bones of the hand has been reported to be 2% to 5%. METHODS: Treatment options have evolved in recent years, and currently include intralesional curettage with or without adjuvant therapy, wide resection, and occasionally amputation...

Peri-prosthetic joint infection remains one of the most difficult and challenging complications following hip and knee arthroplasty for both patients and surgeons. Two-stage revision arthroplasty for infection remains the most popular option for the majority of patients and arguably the only option for some. The use antibiotic spacers and in particular articulating spacers has improved the quality of life for patients between stages. The spacers provides local delivery of high concentration antibiotics and provides many benefits to the soft tissues including maintaining soft tissue tension and range of movement...

BACKGROUND: In young patients with osteonecrosis of the femoral head (ONFH), short-stem total hip arthroplasty (THA) could allow a potential advantage in preserving metaphyseal bone-stock, when revision surgery might become necessary. However, only a few studies have evaluated the outcome of short-stem THAs in ONFH. We reviewed the prospectively collected data of a cementless partial neck-retaining short-stem with ceramic-on-ceramic bearings in ONFH patients. METHODS: Thirty patients (37 hips) younger than 60 years (mean age at surgery, 51...

BACKGROUND: Although use of intramedullary hip screws (IMHS) for intertrochanteric (IT) hip fractures has become more common, limited data have suggested difficulties in conversion to hip arthroplasty. The present study investigates whether conversion of failed IT fracture fixation with an intramedullary vs extramedullary device leads to different rates or types of complications or decreased arthroplasty survivorship. METHODS: One hundred eleven patients were converted to hip arthroplasty after previous surgical treatment of an IT fracture from 2000 to 2010...

INTRODUCTION: Optimal positioning of the patellar component is crucial for the success of a total knee arthroplasty (TKA). Usually, the patellar component is placed empirically over the presumed centre of the patellar cut. Medialization of the prosthetic patella has been recommended; however, no evidence-based guidelines have been reported. MATERIAL AND METHOD: This anatomical study aims to quantify a pre-defined optimal location for positioning of the patellar component with regard to the centre of the patellar cut...

OBJECTIVES: Few studies have assessed outcomes following non-metal-on-metal hip arthroplasty (non-MoMHA) revision surgery performed for adverse reactions to metal debris (ARMD). We assessed outcomes following non-MoMHA revision surgery performed for ARMD, and identified predictors of re-revision. METHODS: We performed a retrospective observational study using data from the National Joint Registry for England and Wales. All non-MoMHAs undergoing revision surgery for ARMD between 2008 and 2014 were included (185 hips in 185 patients)...

Motion at the bone-implant interface, following primary or revision knee arthroplasty, can be detrimental to the long term survival of the implant. This study employs experimentally verified computational models of the distal femur to characterise the relative motion at the bone-implant interface for three different implant types; a posterior stabilising implant (PS), a total stabilising implant (TS) with short stem (12mm x 50mm), and a total stabilising implant (TS) with long offset stem (19mm x 150mm with a 4mm lateral offset)...

INTRODUCTION: Total hip arthroplasty (THA) is a very successful procedure. Revision THA is becoming increasingly common. Recent developments to improve outcomes include the development of large trabecular metal (TM) acetabular cups and augments. There is a paucity of data on the benefit of these new techniques. METHODS: A single-centre retrospective review consisting of a radiological review of post-op revision THA anteroposterior pelvis. Data collection was performed using the Irish National Orthopaedic Register (INOR) and from a previous project...

INTRODUCTION: Trabecular Titanium is an advanced cellular solid structure, composed of regular multiplanar hexagonal interconnected cells that mimic the morphology of the trabecular bone. This biomaterial demonstrated improved mechanical properties and enhanced osteoinduction and osteoconduction in several in vitro and in vivo studies. The aim of this study was to assess Trabecular Titanium osseointegration by measuring periacetabular changes in bone mineral density (BMD) with dual-emission X-ray absorptiometry (DEXA)...

The potentially severe complications related to metal-on-metal (MoM) hip replacements have led to a dramatic decrease of their use. Large diameter heads are more likely to fail than smaller diameters, but complications have been described even with « small » diameters. Therefore, monitoring of MoM arthroplasties is mandatory. This includes physical examination, X-Rays, metal ion levels, and potentially cross-sectional imaging. Despite pathophysiology of adverse reactions to metal debris (ARMD) is better understood, their evolution and the potential systemic complications remain unclear...

Total hip replacement can provide pain relief and restore function in patients suffering from hip arthritis, including in those under the age of 50. However, shortened implant longevity in this age group has been a concern because the clinical results after revision surgery are inferior to those after primary hip arthroplasty. Technical choices (approach, implants, type of fixation and bearing couple) must be made to maximise longevity based on published data and thoroughly discussed with the patient. Finally, long term results (clinical outcome and implant longevity) associated with this surgery are such that it appears unnecessary to postpone the surgery once the indication is established...
