INTRODUCTION: Despite enthusiasm for metal-on-metal bearings, disappointing short- to mid-term outcomes has all but halted the use of this bearing articulation. This review presents mid-term results for the ReCap Magnum total hip replacement. PATIENTS AND METHODS: This prospective study evaluated 79 ReCap/Magnum/Taperloc total hip replacements with mean follow-up of 7.1 (range 3.7-9.2) years. 43 were female and 36 male. Metal ions were measured and radiographic measurement included a 'margin of safety' angle to quantify risk of edge loading...

INTRODUCTION: Cartilage wear is a concern after hemiarthroplasty. The precise pattern of the progression of wear has not been evaluated. We previously reported the application of radiostereonetric analysis (RSA) for the measurement of cartilage wear in patients. The purpose of this study was to report the amount and the orientation of the steady state wear of cartilage between 1 and 3 years after bipolar hemiarthroplasty. METHODS: 22 patients with a bipolar hemiarthroplasty for displaced femoral neck fracture were included...

BACKGROUND: Periprosthetic joint infection (PJI) following total hip arthroplasty (THA) can be treated with irrigation and debridement with head and polyethylene exchange (IDHPE) or 2-stage revision (2SR). Few studies have compared patient-reported outcome measures (PROMs) in patients managed with these treatments. METHODS: A retrospective review identified 137 patients who had an infected primary THA between 1986-2013. Control cohorts were matched according to age and Charlton Comorbidity Index (CCI)...

INTRODUCTION: Most total hip arthroplasties (THAs) in the UK are performed through a posterior or lateral surgical approach. We aimed to investigate any difference in outcome from revision THA according to the approach at primary and revision THA surgery. METHODS: A retrospective cohort study of 205 patients who underwent revision THA for aseptic loosening. Patients rated their pain from 0-10 and completed the Self-Administered Patient Satisfaction Scale (SAPS), Oxford Hip Score (OHS), WOMAC and Short form-12 questionnaires...

PURPOSE: The aim of this work is to evaluate an acetabular antibiotic loaded bone cement spacer in 2-stage revision surgery as a potential approach able to reduce complications during the inter-stage period (i.e. dislocation, acetabular wear), as well as simplify 2-stage hip revision surgery and improve hip biomechanics. METHODS: We performed a retrospective comparative study and evaluated clinical, radiological and surgical data of 71 patients affected by periprosthetic hip infection who were treated with 2-stage exchange...

INTRODUCTION: The femoral canal fill between an anatomic and a straight prosthesis design in cementless total hip arthroplasty (THA) was compared. We hypothesised that the anatomic SPS stem has higher proximal fill and lesser distal fill than the straight stem. MATERIAL AND METHODS: The femoral canal fill was measured on 3 months routine postoperative x-rays at 5 levels of the stem in 50 consecutive patients, aged 35-83 years, who underwent 56 THA procedures by a single surgeon in this hospital...

BACKGROUND: Bone impaction grafting is a biologically and mechanically appealing option in acetabular revision surgery, allowing restitution of the bone stock and restoration of the biomechanics. We analysed differences in proximal migration of the revision acetabular components when bone impaction grafting is used together with a cemented or an uncemented cup. PATIENTS AND METHODS: 43 patients (47 hips), revised due to acetabular loosening and judged to have less than 50% host bone-implant contact were included...

BACKGROUND: Determining the aetiology of persistent pain following total hip arthroplasty (THA) can be challenging. Impingement of the iliopsoas muscle due to a malpositioned acetabular component after THA might be a potential cause of postoperative groin pain. METHODS: We retrospectively analysed the data of 12 consecutive patients from our orthopaedic department who underwent cup revision for painful iliopsoas impingement after primary THA. RESULTS: Thorough physical examination as well as radiological assessment of the included patients revealed that malpositioning of the acetabular component provoked iliopsoas impingement...

INTRODUCTION: Patients who undergo either primary or revision total hip arthroplasty (THA) mainly expect improvement in pain, function/activity and quality of life. The purpose of the study was to measure the degree of short-term and medium-term improvement and the differences in patient-reported outcome that can be expected in patients undergoing revision THA, compared to patients undergoing primary THA. METHODS: In this study, the results of patient-reported outcome measurements were compared in 124 matched patients, who underwent revision surgery and primary THA between 01/2007 and 12/2009...

INTRODUCTION: The outcomes of total hip replacement in patients suffering from residual poliomyelitis are poorly covered in the literature. In this retrospective study we posed the question of whether total hip replacement performed for degenerative hip diseases in limbs with residual poliomyelitis could determine satisfactory mid-term clinical and radiographic results, with a reasonable complication rate. METHODS: A retrospective study was carried out to assess the results of 14 total hip replacements performed on 14 patients with residual poliomyelitis on the involved limb from June 1999 to September 2011...

INTRODUCTION: 15%-20% of patients presenting for total hip arthroplasty (THA) have bilateral disease. While simultaneous bilateral THA is of interest to patients and surgeons, debate persists regarding its merits. The majority of previous reports on simultaneous bilateral THA involve patients in the lateral decubitus position, which require repositioning, prepping and draping, and exposure of a fresh wound to pressure and manipulation for the contralateral THA. The purpose of this study was to compare complications, component position, and financial parameters for simultaneous versus staged bilateral THAs using the direct anterior approach (DAA)...

BACKGROUND: Legg-Calvé-Perthes disease (LCPD) is a paediatric form of osteonecrosis that ultimately heals but will cause femoral head and acetabular deformities. The purpose of this study was to investigate the early serum measurement of osteocalcin in children with femoral head necrosis compared with that of healthy children. METHODS: 20 patients with LCPD (4 girls and 16 boys) and 20 healthy volunteers (5 girls and 15 boys) were enrolled. All patients did not have additional treatment...

INTRODUCTION: The current study was designed to describe types of histological changes within the acetabular labrum in the advanced stages of coxarthrosis, in patients requiring total hip arthroplasty (THA). METHODS: 77 consecutive patients without systemic disorders or prior hip surgery, scheduled for THA with 3 types of coxarthrosis: avascular necrosis (AVN), idiopathic, and dysplastic coxarthrosis were analysed. Patient's data: age, gender, side of the involvement, duration of the symptoms were recorded, and standard anteroposterior (AP) radiographic views of the pelvis were obtained...

AIM: The purpose of this study was to analyse the extent of surgical correction and the early clinical results obtained using periacetabular osteotomy with allogenic bone grafting in patients with severe acetabular dysplasia. METHODS: 44 hips in 38 patients were confirmed to have severe acetabular dysplasia and underwent this procedure. The mean follow-up period was 4.2 (range 1.5-8.2) years. Severe acetabular dysplasia was defined as a centre-edge angle less than 0°, an acetabular-head index less than 50% and an acetabular roof obliquity greater than 30°...

PURPOSE: Eccentric rotational acetabular osteotomy (ERAO) is a modification of rotational acetabular osteotomy (RAO); it has been reported that ERAO allows the femoral head to translate medially and distally. However, no study has compared femoral head translation following RAO or ERAO. The purpose of this study was to compare immediate postoperative translation of the femoral head after RAO and ERAO in comparison with the preoperative position by radiological methods. METHODS: Patients treated by RAO or ERAO between 2006 and 2014 were retrospectively evaluated...

PURPOSE: We assessed the natural history of asymptomatic pseudotumours associated with metal-on-metal hip resurfacings (MoMHRs), and factors associated with future revision. METHODS: In 2007-2008, we identified 25 MoMHRs (21 patients; mean age 59.9 years; 76% female) with asymptomatic pseudotumours. All patients underwent identical initial assessment (ultrasound, blood metal ions, radiographs, Oxford Hip Score [OHS]) and were considered asymptomatic because they denied experiencing hip symptoms, were satisfied with their MoMHR surgery, and had good or excellent OHSs (≥34)...

INTRODUCTION: Ceramic-on-ceramic (CoC) couplings are alternative bearings surfaces that have been reported to reduce osteolysis, wear debris and aseptic loosening compared to the use of polyethylene. Early experiences with ceramics had poor results, but they have led to many improvements in the manufacture and design of subsequent implants. METHODS: We analysed medical files of 300 CoC total hip arthroplasty (THA) with a modular neck performed during period 1995-2000 by a single surgeon for a minimum follow-up of 13 years, evaluating clinical and radiological outcome...
