Filter by:The goal of this observational study is to evaluate the diagnostic performance of the T2 mapping technique of the following 4 MRI scans in detecting hip chondro-labral lesions in comparison with intraoperative arthroscopic findings: 1) basal 3T MRI with T2 mapping technique, 2) 3T MRI with T2 mapping technique and limb traction; 3) 3T arthro-MRI with T2 mapping technique; 4) 3T arthro-MRI with T2 mapping technique and limb traction.
Disturbances of balance and postural stability are frequent in patients with coxarthrosis due to the damage to the mechanoreceptors, characteristic of arthritic degeneration, and muscular hypotrophy of the affected limb. The aim of the study is to evaluate with adequate instrumentation the alterations of proprioception and postural control in patients with hip osteoarthrosis and the effectiveness of joint reconstruction in improving any deficit.
This is a single-site, three-arm, parallel-group randomized clinical trial (RCT). The clinical effects of a nurse-led, very brief, preoperative mindfulness-based intervention for hip and knee replacement patients will be investigated relative to an audio-recorded very brief, preoperative mindfulness-based intervention delivered during the standard nurse consult and a nurse-led preoperative pain psychoeducation intervention during the standard nurse consult.
The primary objective of investigators' proposed study is to demonstrate that the following two cohorts undergoing total hip arthroplasty will have equivalent visual analog scale (VAS) scores up to 3 months post-operatively: one that is administered a modified multimodal analgesic pathway without opioids and the other administered the current standard multimodal analgesic pathway used at Johns Hopkins Bayview Hospital (which includes opioids). The secondary objective is to demonstrate that these cohorts will also have equivalent functional outcomes as determined by both objective measures (such as hip range of motion) and patient-reported outcome measures, such as the Hip Disability and Osteoarthritis Outcome Score (HOOS) and the University of California at Los Angeles (UCLA) activity score.
The objective of this consecutive series PMCF study is to collect data confirming safety, performance and clinical benefits of the G7 Freedom Constrained Liners when used for primary and revision total hip arthroplasty (implants and instrumentation) at 5 years follow-up. Since G7 Acetabular Cup System has only been on the market since 2015, a prospective follow-up will be necessary to obtain data for the 5 year post-surgery time-point for each patient.
This study is a prospective validation study of a new hip and knee replacement-specific questionnaire that can be used to predict postoperative complications. The purpose of this study is to confirm the validity of a new hip and knee scoring system to be used as a clinical tool to predict potential complication rates in patients undergoing total hip or knee replacement surgery. This scoring system aims to stratify patients into specific risk categories based a standardized calculated score. Patients will be evaluated on health risk factors and severity of disease on radiographic imaging prior to surgery, associated to higher complication rates following surgery. The hopeful anticipated result of this study is a prospective validation of the scoring system with both statistical and clinical significance in predicting postoperative complication rates in patients with moderate to high health risk, This stratification system may prove meaningful by allowing these patients, especially those classified as High-Risk, to be incorporated into more appropriate healthcare bundle payment systems that account for their higher financial demands. Furthermore, the stratification may allow for preoperative counseling and a shift towards non-operative management, or surgeon-patient conversations regarding the need to modify a portion of their objective risks prior to surgical intervention. Predictive risk models such as the one presented in the current study will be essential tools as the number of total hip arthroplasty procedures performed each year continue to increase and both the numbers of procedures and associated complications impose a significant cost on the U.S. healthcare system.
This study will examine alterations in muscle in individuals with hip osteoarthritis compared to individuals without hip arthritis. All individuals will receive imaging of their hip and low back muscles in order to compare differences between groups. The investigators hypothesize that there will be differences between groups and that these differences will be related to strength, functional, and balance impairments which will also be measured in all individuals.
This is a prospective study to compare migration of the Microport Prime acetabular cup to a well-established acetabular cup design after total hip replacement. We will enroll 30 patients with the Prime cup and compare migration, function, pain and quality of life to a historical cohort of patients whom had a different cup used during surgery.
The prevalence of severe and disabling osteoarthritis of the hip and/or knee in Albertans is high and increasing. Existing nonsurgical treatments often inadequately control symptoms. Analgesic medications are frequently poorly tolerated in seniors. In these circumstances, joint arthroplasty remains the most evidence based definitive treatment option. In Alberta, wait times for orthopedic assessment and joint arthroplasty are unacceptably long. Additionally, there is a subset of patients who would benefit from joint arthroplasty but are not candidates because they are too young or are poor surgical candidates because of medical comorbidities. There is a great need for a clinically effective and cost-effective nonsurgical treatment option for severe knee and hip osteoarthritis. There is a growing body of published studies consistently documenting a good safety profile for Bone Marrow Aspirate Concentrate (BMAC) injections. The risks and adverse events are comparable to injection of commonly used therapeutic agents (i.e. corticosteroid and hyaluronic acid), including joint swelling (this risk may be increased if the joint was previously affected by gout), stiffness, soreness and, very rarely, infection. The emerging literature also documents promising improvements in pain relief and function. If intra-articular BMAC injection results in safe, significant and predictable relief of pain and disability in Albertans with severe hip and/or knee osteoarthritis, BMAC could offer an expeditious and cost-effective alternative to joint arthroplasty thus shortening arthroplasty wait times. Additionally, patients with severe osteoarthritis who are unfit for arthroplasty could be offered this less invasive intervention. The aim of this trial is to evaluate the safety and effectiveness of BMAC injection in patients with severe hip or knee osteoarthritis.
The aim of this study is to evaluate the effect of a functional task-training program combined with therapeutic ultrasound on pain, strength, gait biomechanics and functionality in adults with hip osteoarthritis.
