INTRODUCTION: Short stems were developed as a bone-conserving alternative especially for the young hip arthroplasty patient. Patients suffering from osteonecrosis of the femoral head are frequently younger than primary arthritis patients. The outcome of short stems in these patients remains unclear. The aim of our study was to compare mid-term survival of short stems after osteonecrosis of the femoral head (ONFH) and primary arthritis. MATERIALS AND METHODS: Data on short stem implantations over a 10-year period were collected...

BACKGROUND: Nontraumatic osteonecrosis of the femoral head (ONFH) is treated with a series of methods. High-energy extracorporeal shock wave therapy (ESWT) is an option with promising mid-term outcomes. The objective of this study was to determine the long-term outcomes of ESWT for ONFH. METHODS: Fifty-three hips in 39 consecutive patients were treated with ESWT in our hospital between January 2005 and July 2006. Forty-four hips in 31 patients with stage I-III nontraumatic ONFH, according to the Association Research Circulation Osseous (ARCO) system, were reviewed in the current retrospective study...

The authors describe a surgical biological reconstruction of the humeral head with frozen autogenous allograft technique for the treatment of young patients with focal osteonecrosis of the humeral head. This represents a possible alternative, maybe even definitive for some patients, when compared to hemiarthroplasty or total shoulder arthroplasty. The technique consists of the fixation of a frozen autogenous allograft with previously-molded articular cartilage from the humeral head, after cleansing the osteonecrotic focus...

BACKGROUND: This study investigated the risk factors for postoperative complications requiring revision surgery within 3 years after transtrochanteric rotational osteotomy (TRO) for osteonecrosis of the femoral head (ONFH). METHODS: We reviewed 127 patients (147 hips) who underwent TRO (anterior or posterior rotational osteotomy) for ONFH between January 2002 and December 2014. Two patients were lost to follow-up, and five patients with progression of femoral head collapse requiring a salvage procedure such as total hip arthroplasty within 3 years after TRO were excluded...

Background: Younger patients undergoing cemented total knee arthroplasty (TKA) may be at risk for lower implant survivorship and higher revision rates due to the historical increased prevalence of aseptic loosening and instability in this cohort. The recent advances of cementless TKAs may mitigate some of these complications. However, there is a paucity of studies reporting on patients who are under 50 years who have undergone a cementless TKA. Therefore, this study evaluated: (I) implant survivorship; (II) functional outcomes and complications; and (III) radiographic outcomes in patients who were less than 50 years of age and underwent cementless TKA...

Total shoulder arthroplasty (TSA) is an effective approach for the treatment of a variety of clinical conditions affecting the shoulder, including osteoarthritis, inflammatory arthritis and osteonecrosis, and the number of TSA implanted has grown exponentially over the past decade. This review gives an update of the major complications, mainly infections, instability and loosening, encountered after TSA, based on a corpus of recent publications and a dynamic approach: The review focuses on the causes of glenoid loosening, which account for 80% of the complication, and underlines the importance of glenoid positioning in the recovery of early shouder function and in the long term survival rate of TSA...

The aim of this study was to determine how an ultra-short anatomic uncemented stem vs a diaphyseal filling five-eighths porous coated uncemented femoral stem (conventional stem) affects the survival of primary total hip arthroplasties in octogenarians. The current study consisted of 52 patients (55 hips) in the ultra-short stem group (mean age, 85.5±5.3 years) and 61 patients (72 hips) in the diaphyseal (conventional) stem group (mean age, 84.1±4.8 years). The predominant diagnosis was osteoarthritis, followed by osteonecrosis of the femoral head, in both groups...

BACKGROUND: Spontaneous osteonecrosis of the knee (SONK) is a clinical entity identified by acute knee pain usually associated with joint effusion, with radiographic findings of a radiolucent defect on the weightbearing area of the femoral condyle. Conservative treatment is initially undertaken; however, surgical procedures are often necessary. Historically, surgical options have included core decompression, cartilage repair, high tibial osteotomy, or joint arthroplasty. Few studies in the literature have reported the use of fresh osteochondral allograft (OCA) for the treatment of SONK lesions...

Background and Objectives Knee osteoarthritis (OA) is a significant public health burden. Rates of total knee arthroplasty (TKA) in OA vary substantially between geographical regions, most likely due to the lack of standardised indication criteria. We set out to define indication criteria for the German healthcare system for TKA in patients with knee OA, on the basis of best evidence and transparent multi-stakeholder consensus. Methods We undertook a complex mixed methods study, including an iterative process of systematic appraisal of existing evidence, Delphi consensus methods and stakeholder conferences...

INTRODUCTION: Core decompression (CD) with or without the addition of autologous bone graft (CDBG) is currently the most widely accepted treatment for hip osteonecrosis in stages of pre-collapse. The use of bone marrow mesenchymal stem cells (CDSC) is emerging as a promising biological alternative. We sought to determine the total hip arthroplasty (THA) conversion rate for patients treated with CD, CDBG or CDSC. MATERIAL AND METHODS: Between 1996 and 2012, 97 cases were evaluated in 72 patients: 47 CD cases, 34 CDGB cases and 16 CDSC cases...

BACKGROUND: Modern management of human immunodeficiency virus (HIV) infection has afforded patients longevity while increasing the burden of arthroplasty procedures because of the increased risk of osteonecrosis, fragility fractures, and degenerative joint disease. Early publications on hip and knee arthroplasty in HIV-positive patients reported a high risk of complications, although some more recent publications demonstrated acceptable outcomes. Despite the widespread nature of the HIV pandemic, there is a paucity of literature addressing outcomes following joint arthroplasty in infected patients...

BACKGROUND: The purpose of this study is to clarify interobserver and intraobserver reliabilities of the three-dimensional (3D) templating of total hip arthroplasty (THA). METHODS: We selected preoperative computed tomography from 60 hips in 46 patients (14 men and 32 women) who underwent primary THA. To evaluate interobserver and intraobserver reliability, 6 orthopedic surgeons performed 3D templating twice over a 4-week interval. We investigated intraclass correlation coefficients (ICCs) and percent agreement of component size and alignment, comparing morphological differences in the hip...

INTRODUCTION: The management of osteonecrosis (ON) of the femoral head remains controversial. It is unclear the extent to which non-arthroplasty procedures are used and there has been no previous report of the trends in operative management of ON in the UK. Our objective is to report current trends in management of ON of the femoral head amongst specialist hip surgeons in the UK. METHODS: A single-stage internet-based survey was e-mailed to 352 eligible members of the British Hip Society (BHS)...

Several reports have shown good long-term results with the Birmingham hip resurfacing (BHR) arthroplasty, but little is known about the results in Asian countries where there is a high prevalence of osteonecrosis and developmental dysplasia of the hip, and many females with small femoral head sizes. Therefore, we retrospectively evaluated the long-term clinical results of the BHR in 112 Japanese patients (53 males and 59 females-130 hips) with an average age of 52 years. Implant survivorship was analyzed using the Kaplan-Meier method with the endpoint being revision for any reason...
