Filter by:In order to investigate the role of acetabular cup screw holes for the transport of osteolysis-inducing particles in a total hip arthroplasty articulation, the investigators compare the amount of bone loss around acetabular cups with and without holes. Bone loss is measured with computed tomography at 7 years and 15 - 18 years of follow-up.
Total hip arthroplasty (THA) requires bone reconstruction in case of severe acetabular injury, with risk of dislocation, especially postoperatively. Dual-mobility cups have proved effective in preventing dislocation in THA revision for instability, but their behavior when cemented in a metal reinforcement has been little studied. The present study assessed results for a dual-mobility cup cemented in a metal reinforcement, in terms of aseptic loosening and postoperative instability. A single-center continuous series of 62 patients receiving such an assembly in THA revision was assessed retrospectively at a minimum 5 years' follow-up.
The "ball-in-socket" design of the Medial-Pivot knee system (MicroPort Orthopedics, Arling-ton, Tennessee, USA) aims to reproduce normal knee kinematics by medializing its rotational axis. Thegoal of this study was to measure knee range of motion (ROM) with this implant after a mean follow-up of 10 years and to report the survivorship and long-term clinical and radiological outcomes. Wehypothesized the prosthetic knee would have at least 120◦flexion at 10 years. This was retrospective, single-centre study of 74 Medial-Pivot knees implanted in71 patients (average age of 69 years) between May 2005 and November 2007. All patients who receiveda Medial-Pivot knee were included consecutively. The mean follow-up was 10 years. Clinical and radio-logical assessments were performed using the Knee Society Score (KSS) and Ewald's score. Kaplan-Meirsurvival analysis was used to calculate survivorship.
The consequences of chronically insufficient sleep are both behavioral and medical. . Patients who undergo total knee or hip arthroplasty commonly complain of sleep fragmentation after hospitalization The aim of the present study is to evaluate the changes inrest-activity circadian rhythm (RAR) and objective and subjective sleep quality and perceived pain, untill the 10th hospitalization day, in patients who underwent total knee or hip arthroplasty.
Post operative pain (POP) is a major obstacle on the road to healing, despite the increasing interest in postoperative pain management and development of pain control modalities (1). Postoperative pain is still insufficiently treated with more than 50% of patients suffering from moderate to severe pain early after surgery .Pain after orthopedic surgery is considered especially difficult to manage. Approximately half of total knee or hip arthroplasty patients present with extreme pain immediately after surgery. Total knee and hip arthroplasty often results not only in severe perioperative pain and debilitation, but chronic pain, joint stiffness, and functional disability many months or even years following the procedure. Various modalities of treating orthopedic POP exist, but the optimal management of postoperative pain remains controversial with no clear consensus of the best method.We suggest that acupuncture can be an effective treatment for post operative pain after total knee or hip arthroplasty.
Purpose The purpose of this study is to compare the clinical outcome and the rate of reoperations in a cohort of patients with undisplaced femoral neck fractures treated with internal fixation and patients with displaced femoral neck fractures treated with hip arthroplasty. Methods In a consecutive series of patients we compared the results of internal fixation for undisplaced femoral neck fractures with those of hip arthroplasty for displaced fractures (control group) of elderly patients. Risk of reoperation and patient reported hip function assessed with Harris hip score and WOMAC were used as outcome measurements.
Fractures of the radial head are among the most common fractures in the elbow and represent one-third of all elbow fractures.This retrospective cohort study was performed between 2004 and 2014 at Sundsvall and Umeå University hospital, Sweden. All patients who were operated on between 2004 and 2014 with a radial head arthroplasty for an acute or sequelae due to a caput radii fracture.The aim of this study is to evaluate clinical or radiological differences between patients treated with a unipolar or bipolar radial head arthroplasty.
The study's primary objective is to compare the following parameters between wound closure following primary TKA with and without supplement tissue adhesive (Leukosan®):
The purpose of the study is to investigate the efficacy of sleep medicine in the recovery of orthopaedic shoulder arthroplasty patients. The investigators hypothesize that a multimodal sleep pathway including non-pharmacological sleep hygiene interventions and the use of zolpidem can improve patient sleep, pain control, and subsequent recovery after undergoing total shoulder arthroplasty.
Total knee arthroplasty (TKA) is a well-established modality for the treatment of advanced knee osteoarthritis with high satisfaction rate. However, the traditional cutting jigs for distal femur cutting inevitably violates the medullary canal of femoral bone. The process of intramedullary reaming for the insertion of distal femur cutting jigs stimulated the dissipation of marrow emboli that reported lead to increased risk of myocardial infarction or cardiac stress perioperatively. There are emerging refinements aiming to reduce the insult to the medullary canal of the distal femur as well as to improve the prosthetic alignment, such as navigation assisted TKA or robotic surgery. In addition to better prosthetic alignment, computer-assisted navigation TKAs also mitigate perioperative blood loss and systemic emboli. The publication previously published by the investigators showed that navigation TKAs can lead to lesser extent of elevation of endothelial injury markers than the traditional TKAs. However, the detrimental effects of intramedullary reaming seem to be multi-dimensional and the whole picture has not been elucidated clearly at present. Previous studies have shown that operative trauma can trigger marked immune responses. Operative procedures can simultaneously stimulate the pro-inflammatory and anti-inflammatory response, with 80% of the leucocyte transcriptome being affected. Most studies of hip or knee surgery found that operation-triggered immune reactions are associated with postoperative recovery, infection, and even mortality. The navigation TKAs avoid the process of intra-medullary reaming, which is the mandatory part of conventional TKA for the distal femur cutting. The investigators hypothesize that the reaming process may exert substantial inflammatory response, which can be manifested by higher level of inflammatory markers in the serum and hemovac drainage samples obtained from the participants undergoing conventional TKAs.
