Active clinical trials for "Osteoarthritis, Knee"

In this study, a functional evaluation of total knee arthroplasty (TKA) patients is performed. The patients are measured prior to surgery and 6 and 12 months after surgery. The measurements consist of questionnaires and rising from a chair. Also, two types of TKA are functionally evaluated. At last, the TKA group will be compared to a THP group.

Total knee replacement surgery is commonly performed for patients suffering from severe knee osteoarthritis. However, 20% of patients continue to experience pain after surgery. There is currently no standardized pain management protocol for pain after total knee replacement. Cooled radiofrequency ablation has been used successfully to alleviate spin-related pain and has recently been approved by the FDA to treat chronic knee arthritic pain. This pilot study aims to collect preliminary data on the use of cooled radiofrequency ablation in patients undergoing total knee replacement.

Observational study.

The primary purpose of this investigation is to report the short-term clinical outcomes (2-3 years) of patellofemoral arthroplasty implanted using the MAKOplasty knee resurfacing system.

The knee prosthesis is a validated treatment for end-stage osteoarthritis, and this intervention usually provides a significant improvement in the quality of life of patients. However, a significant percentage of patients (up 30%) say disappointed with the outcome of the intervention. One hypothesis that could explain these poor results might be poor adaptation of the implants to the patient's anatomy, resulting in a non-physiological kinematics for the patient. Multiple studies try to obtain an individual adaptation of the intervention according to multiple criteria. The measurement of the kinematics of the knee before surgery could participate in this process.

This study seeks to find out if the tibial and patellar components of the Stryker Triathlon Tritanium primary total knee replacement achieve adequate fixation to the underlying bone.

The investigators assessed overall physical activity and sleep quality in subjects with knee osteoarthritis(OA) at baseline, and at four and 12 weeks following initiation of physical therapy. Subjects received a course of manual physical therapy with interventions targeted to relevant impairments in the lower quarter. No progressive activity intervention or guidance on sleep hygiene was included. The purpose of this study was to assess a relationship between manual physical therapy and habitual physical activity and sleep behavior in individuals with knee OA.

The observation of the clinical use of the Delivra Celecoxib cream (8%) in the treatment of osteoarthritis of the knee. Observations will be made over 12 weeks of treatment. Evaluations include: pain, functionality and patients global assessment of disease. Patients will self administer treatment as prescribed.

The objective of this study is to determine and compare the in vivo kinematics and vibroarthrography (VAG) signals for subjects implanted with Journey II Bi-Cruciate Stabilized (BCS), CR (Cruciate Retaining), and Bi-Cruciate Retaining (XR) TKAs.

The OA and Football Study is an epidemiological study designed to establish the prevalence of knee osteoarthritis in retired professional footballers. The study will also identify the key risk factors associated with knee osteoarthritis. The study is comprised of three phases: Phase I involves the dissemination of a questionnaire (demographic details, players history, injury and surgery and other known risk factors of OA), Phase II is a radiographic study that involves x-rays in a sample of footballers both with and without knee pain and Phase III is a case control study which will compared retired professional footballers with age-matched controls recruited from the general population in the East Midlands region.
