Filter by:The investigators are comparing the range of movements the knees of patients who had total knee replacement surgery for knee osteoarthritis. In the study arm, the implant used was a Sigma Cruciate Retaining (CR) Press Fit Condylar (PFC) 150, which is a high flexion knee system designed to combine function with wear resistance. It can accommodate up to 150 degrees of knee flexion. In the cohort arm, the implant used was the standard Sigma CR which can accommodate up to 120 degrees of flexion.
The goal of the study is to know if the reconstruction of the lower limb mechanical axis and the patient knee function is improved after Total Knee Arthroplasty (TKA) using patient specific instruments.
The purpose of this study is to compare an orthopaedic manual physical therapy (OMPT) to corticosteroid injection for the management of knee osteoarthritis.
In the majority of patients with osteoarthritis of the knee the disease originates in the medial compartment. There are two different approaches to replacing this arthritic area. Some surgeons feel that it is always best to replace both the knee compartments with a Total Knee Replacement (TKR). Others feel it is best to replace just the damaged component of the knee with a Unicompartmental Knee Replacement (UKR). There is little agreement amongst knee surgeons. Both interventions are established and well documented procedures, yet little evidence exists to support either practice. Each intervention is considered standard care. There exists little evidence, however, to prove the clinical and cost effectiveness of either management option. The aim of the Total or Partial Knee Arthroplasty Trial (TOPKAT) will be to assess the clinical and cost effectiveness of Total Knee Replacements versus Unicompartmental Knee Replacements in patients with medial osteoarthritis. This will be examined using an appropriate patient base and long term assessments. The trial has a combined device/expertise based allocation depending on the local situation. Surgeons who are in equipoise and have sufficient experience to perform both TKR and UKR, randomisation and allocation can be based on "device" (UKR or TKR). The same surgeon will perform the operation for both arms of the study. For surgeons who hold a preference for one treatment over the other, an "expertise" based randomisation will then occur. UKR surgeons will work alongside TKR surgeons. Patients recruited to the study from these sites will be randomised to one of the treatment options and treated by the appropriate surgeon. In such cases the patient is internally referred to the other surgeon's operating list. Patients will be recruited by their consultant knee surgeons in collaboration with the local research team. TOPKAT are hoping to recruit 500 patients altogether, with 250 per arm of the trial.
We will conduct a large randomized controlled trial comparing the effectiveness and cost-effectiveness of Tai Chi mind-body exercise and standard-of-care Physical Therapy for Knee Osteoarthritis.
The purpose of this study is to compare the the Nexgen knee replacement system using cementless fixation with the same system using cemented fixation. At minimum 2-year follow-up, the hypothesis is that NexGen total knee arthroplasties using cementless and cemented fixation will demonstrate no differences in clinical outcome based on Oxford and Knee Society scores, patient-assessed visual analog pain, clinical complications, radiographic fixation and implant survivorship.
The purpose of this study is to determine whether: 1. Progressive resistance training improves pain and disability 2. Progressive Resistance training improves muscular strength, ability to walk and quality of life
Osteoarthritis (OA) is the most common joint disease associated with aging. Although many patients take glucosamine supplements as a non-traditional treatment for osteoarthritis, the effectiveness of these supplements is questionable. This study will evaluate glucosamine therapy by directly analyzing two functions of joint fluid that are impaired by osteoarthritis - namely, the abilities to lubricate the joint and absorb shocks during activity. Joint fluid samples will be collected from subjects with knee osteoarthritis and analyzed on a device that simulates typical joint movements. After 3 months of glucosamine supplementation, samples will be collected again to detect potential improvements in joint fluid function.
Knee Osteoarthritis (OA) accounts for a significant proportion of mobility limitations and is one of the most disabling problems facing the growing population of older adults. The purpose of this research is to reduce disablement of older adults with symptomatic knee osteoarthritis.
The aim of the project is to assemble and to follow on a 10-year period a nationwide representative sample of lower limb OA patients. General objectives: To document the natural history and to identify predictive factors of the evolution and consequences of hip and knee OA in terms of pain, functional disability, structural damage, quality of life, autonomy, medical and health care use and cost of disease.
