: Recent reports suggest that uncemented total hip replacement arthroplasty (THR) results in favorable short- to mid-term clinical results. In the present study, we assessed the mid-term clinical results of VerSys Hip System uncemented THR at our hospital. MATERIALS AND METHODS: We studied patients who received THR using VerSys Hip System and who could be followed-up more than 3 years. Clinical records were used to retrospectively identify patient characteristics, which included age, gender, disease requiring THR, preoperative and postoperative pain score of the Japan Orthopaedic Association scoring system, range of motion in flexion and abduction, operating time, intraoperative complication, and additional operation or revision surgery...

BACKGROUND: Patient-reported scoring systems have recently been used after surgical procedures. The purpose of this prospective study was to evaluate the patient-reported outcomes of femoral osteotomy and total hip arthroplasty (THA) for osteonecrosis of the femoral head (ONFH). METHODS: Forty-two symptomatic ONFH patients with asymptomatic contralateral hip underwent either transtrochanteric anterior rotational osteotomy (ARO) or THA as a primary operation. Of these, 20 patients whose contralateral hips remained asymptomatic at the final follow-up (more than 1 year postoperatively) were recruited to participate in this study...

To present the morphological changes of classic primary versus rapidly progressive and secondary hip osteoarthritis (HO) and to examine the expression of two pluripotent mesenchymal stem cell-like markers in the synovial membrane. A prospective observational study was conducted in 57 consecutive cases of radiologically confirmed HO in which total hip arthroplasty was performed. Based on the radiological and clinicopathological features, the cases were divided into three categories: classic primary HO (group A; n=16), rapidly destructive HO (group B; n=24), and HO secondary to avascular osteonecrosis of the femoral head (group C; n=17)...

BACKGROUND: Total hip arthroplasty (THA) for sequelae of Legg-Calve-Perthes disease (LCPD) involves specific concerns for deformity, leg length discrepancy (LLD), and relatively young age. Excellent long-term outcome has been proven after Alumina-Alumina (Al-Al) THA for relatively young patients, however, there was no study for Al-Al THA for LCPD sequelae. The aim of this study is to evaluate the results of Al-Al THA for LCPD sequelae and to compare the results with those for adult-onset ONFH, in which THA is necessitated in relatively young age and excellent long term outcome has been proven after Al-Al THA...

BACKGROUND: Osteonecrosis of the femoral head (ONFH) is a debilitating disease in orthopedics, frequently progressing to femoral head collapse and osteoarthritis. It is thought to be a multifactorial disease. ONFH ultimately results in femoral head collapse in 75-85% of untreated patients. Total hip arthroplasty (THA) yields satisfactory results in the treatment of the end stage of the disease. However, disease typically affects males between the ages of 20 and 40 years and joint replacement is not the ideal option for younger patients...

Osteonecrosis of the femoral head (ONFH) following femoral neck fractures is a rare, yet severe, disorder in children and adolescents. This study evaluated the effectiveness of core decompression (CD) combined with implantation of bone marrow-derived cells (BMDC) and rhBMP-2 for osteonecrosis of femoral head (ONFH) after femoral neck fractures in children and adolescents. This study included 51 patients, aged 11.4-18.1 years, with ARCO stages I-III ONFH after femoral neck fractures between 2004 and 2010. The hips were divided into two groups based on whether the lateral pillar of the femoral head (LPFH) was preserved: LPFH and non-LPFH groups...

Bone metabolism is affected by mechanical, genetic, and environmental factors and plays a major role in osteoporosis. Nevertheless, the influence of environmental pollution on the occurrence of osteoporosis is still unclear and controversial. In this context, heavy metals are the most important pollutants capable to affect bone mass. The aim of this study was to investigate whether heavy metals accumulation in bone tissues could be related to the altered bone metabolism and architecture of osteoporotic patients...

This study aimed to compare the microstructure and nanomechanical properties of single trabecular bone in different regions of osteonecrosis of the femoral head. Osteonecrotic femoral heads were taken from 20 patients undergoing total hip arthroplasties between 2011 and 2014. Following incision, resin was embedded and polished, and divided into four regions according to the type of pathologic change; i.e., subchondral bone, and necrotic, sclerotic, and healthy regions. Indents from a single trabecular bone of each region were randomly selected to undergo nanoindentation...

INTRODUCTION: Osteonecrosis of the femoral head (ONFH) is a devastating disease with complete collapse of the femoral head often reported in greater than 70% of patients within 3 to 4 years of diagnosis. Early intervention prior to collapse may improve the chance of success of joint preserving procedures. QUESTIONS/PURPOSES: The purpose of this study was to evaluate whether core decompression with mesenchymal stem cells combined with bisphosphonate therapy can improve the clinical outcomes and reduce the risk of hip replacement when compared to treatment with bisphosphonate therapy alone...
