Filter by:Leg length discrepancies following total hip arthroplasty have been associated with nerve palsies, gait abnormalities, and lower back pain. Leg length discrepancies are related to poorer functional outcomes and patient dissatisfaction. Failure to restore femoral offset following total hip arthroplasty has been linked to decreased range of motion and abductor muscle strength, impingement, limping, higher dislocation rates, increased polyethylene wear, and loosening of implants. Computer navigation has shown to improve the accuracy of leg length and hip offset during total hip arthroplasty. The investigators research objective is to prove the accuracy of the Intellijoint HIP™ system for determining leg length and hip offset. The investigators hypothesis was that Intellijoint HIP™, an imageless intraoperative intelligent instrument, could improve the accuracy of leg length and hip offset during primary total hip arthroplasty. The investigators plan to study this hypothesis in humans by comparing the leg length and hip offset discrepancies produced with Intellijoint HIP™ to the standard at the investigators institution, which is a pin and outrigger system.
The objective of this study is to assess the changes in daily physical activity and gait pattern, following a viscosupplement injection among a population who is suffering from hip osteoarthritis. A kinetic and kinematic gait analysis, an Actigraph activity monitor, a functional Timed-Stair-Test and two questionnaires (Medical Outcome Study Short-Form36 (MOS-SF36), Hip disability and Osteoarthritis Outcome Score (HOOS)) about how the pathology affects the quality of life, will be use.
The purpose of this study is to determine which of the following drugs: enoxaparin, dabigatran and rivaroxaban causes least blood loss after total hip replacement (THR).
Pain and reduced function are the most common symptoms of coxarthritis. Pain relief and normal range of motion (ROM) restoration are the objectives of a Total Hip Arthroplasty (THA) procedure. It is recognized that increased head-neck ratio results in increased ROM due to the fact that prosthetic impingement between neck and acetabular liner occurs with wider arcs of motion. This head-neck ratio has been investigated extensively only in vitro (on cadavers or sawbones) or using mathematical modeling in computer simulations. These studies are limited by the lack of soft tissues and muscle activations in the models. This study will clinically assess the effect of prosthetic head diameter on patient capability of performing movements which require extreme arcs of motion of the hip joint. Therefore, the research questions are: - What role do soft tissues play in limiting ROM? - Can prosthetic impingement really occur in a well positioned THA? - Can a bigger head diameter alone reduce the risk of impingement?
The investigators believe that the application of non-linear methods of analysis using the ganglion and neural network technique will make it possible to analyse all of the complex data obtained in patients with hip osteoarthritis before and then after total hip replacement, and should allow us to identify a combination of objective variables to classify the surgery as " successful " or " unsuccessful ". To this end, the study will take place as follows: Step 1: Screening, and inclusion. Step 2: Evaluation of the hip osteoarthritis and analysis of locomotor activity Step 3: Total hip replacement Step 4: Clinical evaluation of locomotor activity carried out between 6 months and 1 year after the THR Step 5: Data analysis
The aim of the present study is to explore the most efficient surgical approach in total hip replacement in short and long term when concerning strength, functionality and postoperative complications. The objective is to register muscular strength, hip joint functionality/mobilisation and complications after total hip arthroplasty (THA) performed by two minimal invasive/incision surgeries (MIS) versus the traditionally lateral approach. The primary working hypothesis is that due to a minimal dissection and reduced trauma in the muscles, patients will tolerate early hospital discharge better after MIS than after traditional lateral surgery. Patients in the MIS group will also be more active and maintain muscular strength and hip joint functionality/mobilisation better than patients in the lateral group.
To pilot test an activity-focused intervention that educates patients undergoing total hip (THA) or total knee (TKA) arthroplasty due to osteoarthritis about the appropriate type, frequency, intensity, and duration of expected leisure activities after surgery and to determine if the intervention changed expectations.
This randomized clinical trial will evaluate the efficacy of an antiresorptive osteoporosis drug (denosumab) in prevention of periprosthetic bone loss and in promotion of implant osseointegration (bone bonding) in postmenopausal women after total hip replacement. The investigators assume that denosumab prevents periprosthetic bone loss and enhances bone bonding of the hip stem in postmenopausal women.
The objective of this study is to compare the clinical efficacy of intra-articular injections of autologous platelet rich plasma (PRP) vs hyaluronic acid (HA) for symptomatic early osteoarthritis (OA) of the hip. Secondarily, this study aims to determine the feasibility and safety of treating early OA of the hip with HA and PRP.
The primary objectives of this clinical study include: - Evaluate E1 Wear including early bedding-in process, clinical outcomes on patients who received Total Hip Arthroplasty with E1 - Compare E1 wear used with CoCr and Biolox Delta heads
