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...

Total hip arthroplasty (THA) is one of the successful and cost-benefit surgical treatments. One-stage bilateral THA (BTHA) has a large number of advantages, although there are concerns about the higher complications in this procedure. Aim of our study was to evaluate the complications and outcomes of cementless one-stage BTHA in osteoarthritis patients. A total of 147 patients from 2009 till 2012, underwent one-stage BTHA in Milad and Erfan hospitals, Tehran, Iran. A prospective analysis of the functional outcomes and complications of one-stage BTHA through Hardinge approach in patients with osteoarthritis was performed...

INTRODUCTION: Since the first measurement method of patella height in 1929 (Janssen), more than 16 methods have been described. Most of these measures are not suitable to measure patella height after total knee arthroplasty (TKA). One of us (JC) modified the original Caton Deschamps (oCD), index with a new relative index called modified Caton Deschamps (mCD) index, by using new landmarks. The purpose of this study was to determine how patella height is modified after TKA. MATERIAL AND METHOD: Sixty primary TKAs were consecutively prospectively enrolled...

BACKGROUND: Total hip arthroplasty (THA) in patients with sequelae of Legg-Calvé-Perthes disease (LCP) is technically demanding because of the disease related deformities occuring in the proximal femur and/or the multiplanar deformities secondary to corrective osteotomies in childhood. Little is known about the long-term outcome of the procedure in this challenging group of patients. METHODS: We carried out a systematic review of the literature to determine the functional outcome, complications and revision rate of THA in patients with sequelae of LCP disease...

BACKGROUND: Surgeon at primary total hip arthroplasty sometimes cannot achieve sufficient cementless acetabular press-fit fixation and must resort to other fixation methods. Despite a predominant use of cementless cups, this issue is not fully clarified, therefore we performed a large retrospective study to: 1) identify risk factors related to patient or implant or surgeon for unsuccessful intraoperative press-fit, 2) check for correlation between surgeons' volume of operated cases and the press-fit success rate...

BACKGROUND: Earlier results with porous tantalum acetabular cups in revision THA generally have been favorable. Recently there has been some evidence presented that porous tantalum cups might decrease the risk of rerevision in the setting of revision hip surgery performed owing to prosthetic joint infection (PJI). As the data supporting this assertion come from a study with a limited study population, examining this issue with a large registry approach may be enlightening. QUESTIONS/PURPOSES: By combining results from two large, national registries, we asked: (1) Do porous tantalum cups show improved survival after revision THA compared with other cementless designs? (2) Does the use of porous tantalum cups influence survivorship when rerevision for PJI is the endpoint? METHODS: A total of 2442 first-time THA revisions with porous tantalum cups and 4401 first-time revisions with other uncemented cups were included in this collaborative study between the Australian and Swedish national joint registries...

INTRODUCTION: Along with the increase of osteoporotic patients in an aging society, complications in surgeries associated with osteoporosis are also increasing. In cementless total knee arthroplasty (TKA), poor primary stability and subsequent initial loosening of the implant may be seen. CASE REPORT: The patient, a 75-year-old Asian woman with a history of osteoporosis, underwent cementless TKA. Knee radiography at 5 weeks postoperatively showed radiolucent lines outlined beneath the tibial tray and around the stem...

BACKGROUND: Loosening and periprosthetic osteolysis are some of the most common long-term complications after hip arthroplasty. The decision-making process and surgical treatment options are controversial. METHODS: We retrospectively reviewed 96 acetabular revisions (91 patients) performed between 2002 and 2012, with a minimum of 2 years of follow-up and a mean of 5.7 years of follow-up. Clinical outcome was assessed using the Harris Hip Score. The size and location of osteolytic lesions were evaluated using the preoperative radiographs; healing of the defects was categorized using a standardized protocol...

In this paper, the effects of geometric parameters on the development of stress in custom cementless hip implant have been studied. Taguchi methods and analysis of variance (ANOVA) were used to find out which geometric parameters are statistically significant for the maximum von Mises stresses in the hip implant. The multiple regression analysis was also performed, to replace the FE solver and accurately and quickly predict the stress values for new patients. Three parameters horizontal offset (HO), vertical offset and neck shaft angle (NSA), with three levels have been selected...
