Filter by:Knee osteoarthritis (KOA) is a major public health problem among the elderly and is associated with considerable disability. Previous studies on the pathogenesis of this disease mainly focus on cartilage degeneration, but lack of attention to synovitis lesions, and even believe that it is a secondary change in the pathogenesis of osteoarthritis.In recent years, a large number of studies at home and abroad have pointed out that the occurrence and development of knee osteoarthritis are accompanied by synovitis at each stage, and synovial lesions may be the primary manifestation of knee osteoarthritis and affect the evolution of knee osteoarthritis.To this end, some scholars proposed that synovitis lesions as a starting point, may be a new target for the treatment of knee osteoarthritis.
It is stated that after arthroplasty surgery, besides the physiological factors, the factors related to the individuals may affect the recovery. Among these factors, one of the most defined in the literature is kinesiophobia. Although kinesiophobia is defined as the terms of "fear of movement" and "fear related to pain"; There are also definitions for situations in which fear of movement is most extreme or pain-related fear avoidance beliefs. Kinesiophobia, which usually occurs in the preoperative period and supports the development of chronic pain, may also affect the early recovery findings. It is very important to determine the presence and severity of kinesiophobia as it is associated with functional results after surgery. Individuals' perceptions about themselves, expectations of recovery, and personal beliefs before surgery are thought to affect recovery in the early period. In the studies conducted, it was stated that individuals with high perception about himself and the surgical process recover faster and return to activities. However, it is emphasized that studies should be conducted on the effect of individuals' personal factors such as self-efficacy, self-perception and their perspective on health on the healing process.
Sponsor is conducting this post market clinical follow-up (PMCF) study to evaluate the safety and efficacy of its EVOLUTION® Revision CCK Tibia and EVOLUTION® Revision CCK Femur with EVOLUTION® CCK Tibial inserts. These type of studies are required by regulatory authorities for all devices that have been approved in Europe (EU) to evaluate the medium and long term clinical evidence. This study has been designed in accordance with MEDDEV2.12/2 rev 2 (European Medical Device Vigilance System) and ISO (International Organization for Standardization) 14155:2011 guidelines.
PURPOSE: To compare the effect of hyaluronic acid (HA) or platelet-rich plasma (PRP) on pain, physical function, quality of life and knee joint morphology in patients with knee osteoarthritis severity II-III. BACKGROUND: Knee osteoarthritis affects quality of life significantly because it is the most common joint disease and causes considerable disability. Pathogenesis is multifactorial, nevertheless reduced cartilage production, increased destruction, and synovial inflammation are important factors in the osteoarthritis process. Today, symptomatic drugs are commonly used in the treatment of osteoarthritis, but these treatments have limited effects on cartilage degeneration. Intraarticularly, hyaluronic acid (HA) and platelet-rich plasma (PRP) treatments have been used for osteoarthritis due to pain and functional effects. HA has been shown to reduce the levels of collagen degradation products and maintain normal cartilage metabolism. PRP is thought to have positive effects on clinical and tissue healing due to the numerous growth factors involved. However there is no research to prove definitively that one of the two applications in knee osteoarthritis is superior to the other. METHOD: 120 patients between the ages of 50-70, OA severity II-III will be included in the study. Patients will be stratified according to the severity and age of OA, and two groups will be randomly assigned as HA and PRP. HA and PRP injections will be performed two times and one month apart. Outcome measures are pain, physical function, quality of life, muscle strength, WORMS, and patient satisfaction. Each patient will be examined at baseline, first, third, sixth, ninth and twelfth months.
Stromal vascular fraction of cells (SVF) will be extracted from lipoaspirate by enzymatic digestion. SVF will be administered in a single dose intraarticularly 4 weeks after arthroscopic debridement. All patients will receive cell therapy.This is a single arm study with no control.
The focus of the study is to determine the prevalence and variance of self-reported knee pain characteristics in a community-derived sample of adults aged 40 years and over. It will also identify characteristics such as structural changes of osteoarthritis of the knee as well as physiological parameters and blood and urine biomarkers.
This study aims to compare the efficacy between Boonme stick exercise and quadriceps strengthening exercise in knee osteoarthritis.Patients diagnosed as knee osteoarthritis using Altman criteria will be randomized into 2 groups using simple random technique. Patients will be instructed and trained for both quadriceps or Boonme stick exercise by one-trained physical therapist. All patients will be treated with behavioral modification, NSAIDs and analgesic drugs and regularly follow-up . Assessment included visual analogue scale, exercise compliance, WOMAC and patient satisfaction were done by an assessor in a blinded fashion.
The purpose of this study is to find if autologous stem cell transplantation can improve clinical manifestations of knee osteoarthritis.
