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.
Tourniquet use during total knee replacement (TKR) improves visibility, significantly decreases intra-operative blood loss and reduce operative time. However, tourniquet use also has a negative effect on postoperative pain, postoperative range of motion(ROM), wound complication, deep vein thrombosis (DVT), pulmonary embolism (PE), thigh muscle strength, and functional recovery after TKR. Therefore, the investigators conducted a three-arm prospective, randomized, controlled trial study to compare the efficacy of different tourniquet pressure used between systolic blood pressure + 75 mmHg, systolic blood pressure + 100 mmHg, and systolic blood pressure + 150 mmHg.
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.
Knee osteoarthritis (OA) is a highly prevalent condition that results in substantial pain and loss of function. The end stage treatment for knee OA is total knee arthroplasty (TKA), a common and safe procedure typically performed for relief of symptoms. However, an increasing number of patients are complaining about their TKA due to altered sensations between their previous joint and the implant. Although several designs have been proposed to improve these outcomes, the knee kinematics after TKA remains different from physiological kinematics. The Medial Pivot TKA design was introduced to closely mimic normal knee kinematics and create the natural feeling of the knee. This study is intended to evaluate the clinical effectiveness and ability to restore knee motion of two TKA devices: the Medial Pivot Persona TKA Zimmer design with the traditional Zimmer Persona Knee-PS. The investigator's hypothesis is that the Medial Pivot design will results in better patient outcomes and restore knee motion at natural parameters.
To evaluate a new, low intensity ultrasound device in the treatment of chronic pain due to osteoarthritis in the knee. Enhancing CBD oil penetration into joints by sonophoresis.
The purpose of this study is to follow the patient's short term and long term clinical outcome after undergoing joint replacement surgery.
The social impact of degenerative diseases such as articular cartilage pathology and osteoarthritis (OA) is steadily increasing, because of the continued rise in the mean age of the active population. A variety of noninvasive solutions have been proposed for pain treatment, improvement in function and disability, and ultimately, modification of the course of severe cartilage lesions and OA, with variable success rates. Intra articular and genicular nerves radiofrequency (RF) is a minimally invasive technique that usually aims at the neuropathic pain. One important mechanism for the chronic pain mediated by OA is peripheral sensitization, which increases the transmission of pain signals. Through conduction block in pain-transmitting nerve fibers by thermal damage, RF could ease pain without destroying the antennal nerve. The role of growth factors (GFs) in chondral repair is now widely investigated in vitro and in vivo. Platelet-rich plasma (PRP) is a simple, low cost, and minimally invasive method that allows one to obtain from the blood a natural concentrate of autologous GFs.
The purpose of this study is verify the efficacy and safety of Cettum (Electric moxibustion) for patients with knee osteoarthritis.
This is an early user evaluation of the robotic-assisted total knee arthroplasty platform. The objective of this surgeon group is to capture data on the defined objectives and provide Stryker with feedback.
