Filter by:The success of total knee arthroplasty depends on a number of factors including pre-operative range of movement, obesity, medical comorbidities, prosthesis design, preparation and implantation of the prosthesis, soft tissue balancing, as well as implants alignment. Optimal placement of the implants within 3° of the mechanical axis of the lower limb has been proven to reduce wear and early implant failure. Compared to conventional techniques, computer-Aided Navigation total knee arthroplasty has been widely used in the last decade and have been proven to improve the accuracy of prosthesis placement and lower limb alignment by reducing the number of outliers with more than 3° deviation from the mechanical axis. However, its use also involves a steep learning curve, high initial capital cost and longer duration of surgery. Traditional computer-navigated TKA using optical tracking systems also requires fixation of the femoral and tibial reference arrays to bone using anchoring pins. Complications reported with the use of these pins include either femoral or tibial fracture, pin site pain, pin site infection and osteomyelitis. The investigators study aims to investigate the accuracy of a new pinless navigation system for TKA that will avoid these complications.
This study is intended to gather medium (0-5 years) and long-term (6-10 years) information regarding the performance and safety of the commercially available Ceramax™ Ceramic on Ceramic Total Hip System. This is a two-phased study consisting of a clinical follow-up phase and a clinical outcomes phase. In Phase One (0-5 years), diagnostic, demographic and operative information will be gathered for each subject enrolled in this study. In addition, Harris Hip Evaluations, subjective evaluations and radiographs will be completed annually. In Phase Two (6 - 10 years), a subjective outcomes questionnaire and a SF-12 Health Survey will be mailed to subjects annually.
The purpose of this study is to examine whether an magnetic resonance imaging (MRI) -guided treatment strategy based on a predefined treatment algorithm can prevent progression of erosive joint damage, increase remission rate and improve functional level in the short and long term in patients with rheumatoid arthritis (RA).
Dysfunction of the jaw, associated with pain in the jaw or about the jaw in the face can be quite long lasting and debilitating. Dextrose injection with a small needle has be notably helpful in preliminary studies in reducing pain and improving jaw function. This randomized trial will compare dextrose injection with saline injection for temporomandibular(jaw) dysfunction, also known as TMD.
Nuclear Magnetic Resonance Therapy (NMRT) is gaining as a novel mode of therapy in osteoarthrosis. A prospective double blind randomised study of 100 patients was conducted to investigate efficacy of NMRT in the treatment of mild to moderate osteoarthrosis (OA) of the knee joint. The null hypothesis was that there is no benefit of NMRT over placebo in mild to moderate oteoarthosis of the knee.
NOR-DMARD is a register-based longitudinal observational study of which the main objectives are to study the effectiveness of treatment of inflammatory joint diseases with biological disease modifying anti-rheumatic drugs (DMARDs) in clinical practice, by measuring disease activity, health related quality of life, function and joint damage, and to study the long-term safety of such treatment. Other objectives include the assessment of cost-effectiveness of treatment, to identify and and validate clinical, genetic and immunological predictors of efficacy and adverse events, to assess the impact of treatment with biological DMARDs on work participation and work productivity, to investigate different strategies for use of biological DMARDs, to assess the performance of different outcome measures, and to ensure a systematic and timely follow-up of patients treated with biological DMARDs.
The purpose of this study is to evaluate the use and efficacy of the 3DKnee™ System using Vitamin E UHMWPE tibial inserts for total knee replacement surgery.
The primary objective of this investigation is to evaluate survivorship at ten years. For this post approval study (PAS), a maximum acceptable hazard of revision is assumed to be a constant 1% per year.
The purpose of this study is to compare injecting local anesthetic (numbing medication) in different patterns around a major nerve in the leg. Patients who undergo surgery to the lower leg and/or foot are usually offered the option of a nerve block to help with pain control after surgery. A nerve block involves injecting local anesthetic (numbing medicine) by a nerve or nerves that provide sensation to the area where surgery will be performed. The local anesthetic (numbing medication) numbs up the area where the surgery is performed and helps decrease the amount of pain felt after surgery. The local anesthetic (numbing medication) can be injected in various patterns by a nerve, such as in one spot by a nerve or completely surrounding a nerve. The local anesthetic will be either injected around the sciatic nerve or will injected in a way that will split the sciatic nerve into the two component nerves that make it up, the tibial and sciatic, and surrounds each nerve. The hypothesis is that subjects in the group that local anesthetic is injected in a pattern that separates the sciatic nerve into the two component nerves may have a faster onset time of regional anesthesia and block success than subjects in the group that have the local anesthetic injected at around the nerve.
The objectives of this research are to: Conduct a proof of concept randomized controlled trial with up to 300 patients undergoing primary total knee replacement (TKA) at Brigham and Women's Hospital (BWH). The trial will compare a "Care Navigator" post-discharge intervention versus "Usual Care" post discharge management of patients undergoing TKA. The intervention will focus on the challenging process of transitions from the acute care hospital to inpatient or outpatient rehabilitation, and from inpatient rehabilitation to home. The principal goals of the trial are: 1. To establish whether "Care Navigator" intervention improves functional outcomes as compared with the "Usual Care" treatment six months after TKA surgery. 2. To establish whether "Care Navigator" intervention is cost effective six months after TKA surgery. The investigators hypothesize that: 1. Incorporating the Care Navigator role into the "Usual Care" treatment will increase TKA patients' rate of adherence to the rehabilitation protocol and improve functional outcomes. 2. Addition of a Care Navigator is cost-effective.
