Osteoarthritis of Knee

This study aims to investigate whether oral cannabis extracts can effectively manage pain caused by osteoarthritis (OA), a common joint condition affecting one in seven Canadians. Current OA treatments often have limited effectiveness and may cause side effects. As a result, many individuals with OA turn to medical cannabis for pain relief, despite limited scientific evidence supporting its efficacy. The goal of this study is to assess the feasibility of a larger trial evaluating the effects of two cannabis compounds-CBD and THC-compared to a placebo (a look-alike substance containing no active drug) on pain interference in patients with hip and/or knee osteoarthritis. Participants will: * Take either CBD, THC, or a placebo capsule daily for 8 weeks * Complete follow-ups remotely, with no in-person clinic visits required * Maintain a diary tracking their study drug usage and any additional pain medications

Although the primary knee motion occurs in flexion/extension, the frontal and transverse (off-axis) knee motions are smaller but crucial for maintaining joint stability and normal knee loading. Altered kinematics and neuromuscular control in off-axis knee motions have been reported in patients with knee osteoarthritis (OA), which are associated with excessive knee loading and the progression of knee OA. However, traditional rehabilitative treatments for people with knee OA and existing exercise equipment often focus on sagittal plane movement. Probably due to the technical limitations, there is a lack of convenient and effective equipment/method to train patients with knee OA in off-axis (frontal and transverse) planes. The purpose of this study is to use a robot-aided elliptical training device to measure knee neuromechanical properties and to improve neuromuscular control in off-axis knee motions, aiming for joint de-loading and pain reduction for individuals with knee OA.

The purpose of this study is to assess obese patients with knee arthritis and determine the non-inferiority of a low dose steroid treatment vs. standard dose steroid treatment for two knee outcome measures: pain and function.

This study is a prospective, randomized, double-blinded, placebo-controlled study of the drug colchicine in the acute postoperative period for patients who are undergoing a total knee arthroplasty (TKA). Patients aged 18 years or older who are undergoing TKA will be invited to participate in the study. The primary endpoint of this study is to determine if colchicine, an anti-inflammatory medication commonly used for gout attacks, will decrease the postoperative pain of patients undergoing elective TKA.

The menisci of the knee joint are structures composed of cartilage and connective tissue, whose primary functions are to stabilize the joint and distribute weight across joint surfaces. In doing so, it helps protect the joint from osteoarthritis - a form of joint failure commonly referred to as "joint wear". Meniscal surgeries are among the most common orthopaedic procedures performed both in Sweden and globally. Historically, damaged menisci were treated by removing the injured part. However, this approach is linked to early-onset osteoarthritis. Osteoarthritis affects approximately one-third of individuals over the age of 45 and ranks among the ten most common diagnoses in Europe based on years lived with disability. The knee is the most frequently affected joint, and the importance of the menisci in preserving knee function has become increasingly recognized. In recent years, advances in surgical techniques have led to a shift towards meniscus-preserving procedures. A typical injury is the displaced meniscus, in which a large portion of the meniscus becomes detached from the joint capsule and wedges itself inside the joint, causing mechanical locking and preventing full extension. A displaced meniscus often loses its blood supply and suffers mechanical damage from being compressed between the joint surfaces. To preserve the meniscus and prevent irreversible damage, early surgical intervention is required. If the injury is too old or the tissue too damaged, the injured part of the meniscus must be removed, which significantly increases the risk of developing early knee osteoarthritis. It remains unclear how soon surgery must be performed to successfully preserve the meniscus, and this likely depends on various other factors, including patient age, presence of additional joint injuries, and surgical technique. There is currently no reliable data on the proportion of displaced menisci that heal after meniscus-preserving surgery. However, studies suggest that 20-30% of repaired menisci require reoperation due to failed healing. Given that displaced menisci are considered surgical emergencies, they pose a significant burden on healthcare systems already strained by limited access to urgent surgery. Meanwhile, ongoing development of surgical techniques raise ethical and logistical questions for health providers - especially as the scientific evidence for the benefits of some advanced treatments remains inconclusive. Therefore, more research is needed to guide the optimal management of displaced bucket-handle lesions across a diverse patient population, taking into account age, activity level, and concurrent injuries. A key priority is to identify predictors of healing potential, particularly the time window during which surgical repair remains a viable option. With better knowledge, more menisci could potentially be preserved - reducing both the number of unnecessary re-operations and the long-term incidence of knee osteoarthritis.

Osteoarthritis (OA) is a chronic degenerative disease characterized by the breakdown and repair processes of the cartilage structure in synovial joints. Balneotherapy is one of the most commonly applied treatment methods in patients with OA. It is used to reduce pain and stiffness, improve joint mobility and quality of life, and prevent disease progression. Hyperthermia caused by balneotherapy activates the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis. After heat stress, HSp levels in the blood increase, triggering the HSp-cytokine-HPA-cortisol anti-inflammatory feedback mechanism, resulting in an anti-inflammatory effect and neuroendocrine immune regulation. In various pathologies associated with low-grade inflammation-especially rheumatic diseases-balneotherapy and mud therapy have been reported to decrease serum concentrations of pro-inflammatory cytokines such as TNF-α and IL-1β. Serum COMP levels are elevated in OA patients. There is evidence that measuring COMP levels could serve as a prognostic marker for the development of OA in patients with chronic knee pain. It is evaluated not only as a cartilage marker but also as an indicator of synovial inflammation. The aim of this study is to evaluate the response to inflammation and stress in patients with knee OA by examining the levels of CRP, IL-1 beta, COMP, and HSp following balneotherapy treatment. Additionally, changes in patients' quality of life and functional status after balneotherapy will also be evaluated.Fifty patients with primary osteoarthritis who meet the inclusion criteria and are receiving inpatient or outpatient treatment in the Physical Medicine and Rehabilitation clinic will be included in the study. It is planned to include 30 patients in the treatment group and 20 patients in the control group. Pain will be assessed using VAS, physical function and stiffness using WOMAC, and quality of life using the SF-36 scale. To determine the serum levels of COMP, IL-1 beta, CRP, and HSp70, blood samples will be collected under standard conditions from patients in a fasting state between 8:00-9:00 AM. Biochemical markers will be evaluated using ELISA kits. For balneotherapy, patients will be treated in a thermal pool for 15-20 minutes daily, with full-body immersion, for a total of 15 days.

Joint replacement surgery is an effective treatment for severe joint diseases, but the postoperative recovery process is complex and lengthy. Preoperative rehabilitation training, as an important part of preoperative preparation, has been proven to significantly improve postoperative recovery outcomes. However, there is currently a lack of systematic research on the optimal protocols and duration of preoperative rehabilitation training and their specific impacts on postoperative recovery. This study aims to evaluate the effects of preoperative rehabilitation training on postoperative recovery after joint replacement through a randomized controlled trial, providing scientific evidence for clinical practice.

This study aims to investigate the effects of fatigue induced by isokinetic exercise on passive and active joint position sense in postmenopausal women diagnosed with knee osteoarthritis (gonarthrosis). A healthy control group matched for age and sex will also be included for comparative analysis. Participants will undergo proprioceptive assessments before and after an isokinetic fatigue protocol. We hypothesize that (1) fatigue will impair both passive and active joint position sense in patients with gonarthrosis, (2) active joint position sense will be more affected than passive sense, and (3) the deterioration in proprioception will be greater in the gonarthrosis group compared to healthy controls.

Total Knee Replacement surgery is common procedure that is usually done for patients suffering from persistent pain with limitation of movement. Unfortunately, they do suffer after the operation as it is associated still with significant pain that affect the rehabilitation plan, hospital length of stay, life style and patient satisfaction. New approaches are rising every day to add to the multimodal management plan. Genicular nerves cooled radiofrequency ablation is a new approach that can be simply done U.S. guided with little side effects, if any, and great results.

The goal of this study is to determine whether undergoing bariatric surgery before knee replacement leads to better outcomes compared to undergoing knee replacement before bariatric surgery. Our secondary goal is to compare complication rates between these groups to determine if there is a difference based on the order of the two procedures. Participants will be randomly placed in one of two groups, with each undergoing both procedures but in opposite order. Quality of life will be assessed via questionnaires before and between each procedure, and rates of complications will also be documented to compare their rates between groups.

Osteoarthritis is a degenerative disease affecting joint cartilage and its surrounding tissue. It is the leading cause of disability in the elderly. Photobiomodulation (PBM), has been used widely for alleviation of pain, reduction of inflammation, and acceleration of wound healing, and particularly to treat knee osteoarthritis (KOA). The purpose of the current study is to determine if a near-infrared PBM device (B-Cure Laser), applied at home, by the patient or personal caregiver in a real-life situation, can reduce pain and improve functionality in patients with KOA.

Knee replacement surgery is a surgery designed to treat severe arthritis of the knee. However, as many as 20% of patients are not satisfied with the results of their surgery. To place the knee replacement in correct position, the kinematic alignment method, which tries to reproduce the patient normal anatomy, has shown promise in improving the satisfaction after knee replacement surgery. It is not known if using a robotic arm to assist in surgery is better than the traditional method when trying to recreate kinematic alignment. The goal of this study is to learn if robotic assisted surgery is better than traditional method for knee replacement done using kinematic alignment. The main questions the study tries to answer are: 1. Do the radiographs of kinematic knee replacement surgeries done with robotic assistance show better alignment than radiographs of kinematic knee replacements done with the traditional method? 2. Does robotic assisted kinematic knee replacement give better function to patients than traditional knee replacement done with kinematic alignment? 3. Does robotic assisted kinematic knee replacement decrease pain, improve knee movement and improve knee stability better than traditional knee replacement done with kinematic alignment? 4. Are there more complications with robotic assisted kinematic knee replacement in comparison to traditional kinematic knee replacement? 5. How long long does it take a surgeon to become good a performing a kinematic knee replacement using robotic assistance? Researchers will compare knee replacements done using a robotic to make the bone cuts, and compare it to the usual method using guides and manual instruments. All the knee replacements will be done using the kinematic alignment and with the same type of knee replacement prothesis. Participants will: * Have a knee replacement done with the kinematic alignment technique by an experienced surgeon, with or without robotic assistance during the surgery. * Visit the clinic before surgery, six weeks after surgery, three months, six months, twelve months and twenty-four months after the surgery. * Fill questionnaire, have their knee examined and have radiographs of their knee done at each visit.
