Clinical Outcomes of Intraarticular Platelet-Rich Plasma Injection in Knee Osteoarthritis

This prospective single-arm interventional study was designed to assess the short-term clinical outcomes of intra-articular platelet-rich plasma (PRP) injections in patients with Kellgren-Lawrence grade II and III knee osteoarthritis. A total of 59 patients (61 knees) were enrolled and followed for six months. Pain and function were measured using the Visual Analogue Scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Safety monitoring included documentation of injection-site pain and other adverse events.

Manual Arthroplasty Versus VELYS Robotic-Assisted Solution Functional Alignment Arthroplasty for Knee Osteoarthritis

The goal of this clinical trial is to learn if the VELYS Robotic-Assisted Solution (VRAS) device helps to improve outcomes from total knee replacement, when compared to regular non-robotic-assisted total knee replacement in the treatment of osteoarthritis. It will also aim to review the longer-term safety and efficiency effects of using this device. The main questions it aims to answer are: 1. Does VRAS device-assisted total knee replacement improve patient outcomes (such as their function, satisfaction, and pain) when compared to non-robotic-assisted total knee replacement? 2. Does VRAS device-assisted total knee replacement improve clinical outcomes (such as revision risk, complications, and hospital length of stay) when compared to non-robotic-assisted total knee replacement? 3. Does VRAS device-assisted total knee replacement improve functional outcomes (including biomechanical motion analysis) when compared to non-robotic-assisted total knee replacement? 4. What are the economic and efficiency effects of VRAS device-assisted total knee replacement compared to non-robotic-assisted total knee replacement? 5. What are the human factor and learning curve effects of introducing VRAS device-assisted total knee replacement into healthcare teams? 6. Are there any differences in safety and adverse event incidence between VRAS device-assisted total knee replacement and non-robotic-assisted total knee replacement? Participants will: * Be randomised to receive a total knee replacement using either regular non-robotic-assisted methods, or with the use of the VRAS device. * Be assessed pre-operatively at the clinic, and then at 6 weeks, 6 months, and 12 months following date of operation. At these appointments patients will answer questionnaires, receive an x-ray (pre-operatively, and at 6 months post-operatively), and a subgroup will be reviewed in the motion analysis laboratory (pre-operatively, and at 6 months post-operatively). * Have their longer-term outcomes including any revision operations monitored out to 10 years through national registry data linkage (no actual follow-up for patients after 12 months).

Impact of Pre-operative Sarcopenia on Functional Recovery After Hip Arthroplasty in Older Adults

This single-centre, exploratory study at Montpellier University Hospital will investigate whether having low muscle mass and strength before hip-replacement surgery, a condition called sarcopenia, impact the return to everyday independence in people aged 75 years or older. About 20 volunteers, scheduled for surgery because of a recent femoral-neck fracture or severe arthritis that no longer responds to usual care, will give consent, answer brief health questionnaires, attempt simple walking and chair-rise tests if possible, and provide a small blood sample. While they are already under anaesthesia for their planned operation, the surgical team will take a tiny muscle sample through the same incision, so no extra cuts are needed. During the hospital stay or shortly after discharge, each participant will have a painless MRI scan of the thigh muscles and a very-low-dose bone scan (DXA) to measure muscle and bone health. The research team will then telephone participants at 3 and 6 months to ask about daily activities, walking ability, and any complications. The study lasts about six months for each person and does not alter their usual medical or rehabilitation care. Potential benefits include close follow-up, personalised feedback on muscle and bone results, and helping doctors learn whether pre-surgery muscle weakness predicts slower recovery-information that could guide future, more personalised exercise and nutrition programs. Extra study procedures carry only minimal risks: a routine blood draw, scans with none (MRI) or very little (DXA) radiation, and a muscle biopsy taken during surgery. Taking part is entirely voluntary, and participants may withdraw at any time without affecting their current or future care. The whole project will run for 18 months.

Patient Pain and Function in Medial Knee Osteoarthritis After Anteromedial vs Anterolateral Intra-Articular Corticosteroid Injection

The primary purpose of this study is to find out if there is a difference in pain experienced in patients with knee arthritis of the inside of their knee if they get a steroid injection on the inside or outside of their knee. Participants will: 1. Be randomly divided into getting their steroid injection on the inside or outside of their knee. 2. Answer a pain survey before their injection as well as over the phone 2 weeks, 6 weeks, and 12 weeks after their injection.

Research on the Pathogenesis and Therapeutic Targets of Articular Cartilage Degeneration in Osteoarthritis

Before you are included in this study, you will undergo the following examinations to determine if you are eligible to participate: Before you are included in this study, your doctor will ask and record your medical history, conduct a physical examination on you, and perform necessary imaging tests. 2. If you are more than qualified examination, will study according to the following steps: if you meet the inclusion criteria, will study according to the following steps: (1) when you accept total knee replacement, the doctor will collect a small piece of articular cartilage (0.5 cm x 0.5 cm x 0.5 cm) used for research and analysis. (2) The process of collecting tissue specimens will be carried out by experienced orthopedic doctors, and the entire process will take approximately 5 to 10 minutes. One week and two weeks after the operation, the doctor will follow up with you to understand your recovery progress. 3, other matters need your cooperation: please timely follow-up to the hospital after the operation, so that the doctor evaluate your recovery.

Evaluation of Choose to Move Replacement Ready (CTM-RR)

Choose to Move (CTM) is a 3-month, choice-based health-promoting program for low active older adults being scaled-up across British Columbia (BC), Canada. Recently, the investigators adapted CTM for the \>14000 people in BC who are on surgical waitlists for total knee replacement or total hip replacement (TKR/THR) for osteoarthritis (OA). The primary goals of this observational study are to describe how the adapted program, Choose to Move Replacement Ready (CTM-RR), is implemented in BC and determine if the adapted program improves health outcomes in people with hip and/or knee osteoarthritis who are on surgical waitlists for TKR/THR. The investigators will also evaluate whether any health benefits achieved by CTM-RR participants are maintained three months after they finish the program and also during the remaining time that they wait for their TKR/THR surgery. The investigators will work with referral partners from hospitals and orthopaedic clinics in BC to recruit participants into CTM-RR. Participants who enrol in CTM-RR will answer online survey questions about the program and about their physical activity, mobility, pain, function, quality of life, willingness to undergo surgery, overall perception of their joint condition, psychosocial health, self-efficacy, social isolation, loneliness, and sedentary time. CTM-RR activity coaches will also answer online survey questions about the program. CTM-RR participants, activity coaches, and referral partners will also participate in interviews about the program.

Comparing Ankle Fusion to Ankle Replacement

End-stage ankle arthritis (ESAA) is a debilitating condition associated with severe pain, dysfunction, and reduced quality of life. Many patients with ESAA have difficulty walking for even 100 feet or up a single flight of stairs. Patients seeking surgery for ESAA have two primary treatment options: ankle arthrodesis (i.e., ankle fusion) and ankle arthroplasty (i.e., ankle replacement). Few studies have directly compared the effectiveness of these two procedures, and no randomized controlled trials (RCTs) have been performed. The investigators will compare the following in subjects undergoing ankle arthrodesis and ankle arthroplasty before surgery, and post-surgery at 3 and 6 months, and on an annual basis up to ten years. 1. Overall physical function and ankle specific function 2. Ankle pain intensity and interference with activities 3. Activity levels 4. Overall general health 5. Post-surgical complication rates The investigators will also identify prognostic factors that are predictive of higher physical function, ankle specific function, reduced pain, improved general health, and overall patient satisfaction.

Ultrasonographic Evaluation of Talar Cartilage Thickness in Patients With Spinal Cord Injury

Spinal cord injury patients often present with musculoskeletal comorbidities, including osteoarthritis. Early detection of cartilage damage is important for preventing osteoarthritis progression. This study aims to compare the talar cartilage thicknesses of spinal cord injury patients with healthy subjects. The secondary aim is to investigate a correlation between the talar cartilage thickness and disease-related parameters. The patient group is to be assessed for talar cartilage thickness (via ultrasound), functional status, spasticity, and ambulation levels.

Post-Operative Pain Relief: Zynrelef or Periarticular Injections in RATKA

Prospective Cohort of patients who are scheduled for a Robot Assisted Total Knee Arthroplasty (RATKA). A prospective survey of patient reported outcome measures (Numeric Rating Scale) will be obtained postoperatively of 72 hours, as well as at the postoperative opioid consumption after 72 hours.

Platelet Rich Plasma for Musculoskeletal Conditions

The primary purpose of this study is to follow patients with various musculoskeletal (MSK) conditions over a one-year follow-up period after receiving a platelet rich plasma (PRP) injection, assessing changes in their pain levels, functional abilities, and overall patient satisfaction. This will develop a robust registry of patients treated with PRP for a range of MSK conditions. These conditions include, but are not limited to, osteoarthritis (OA) of the knee, hip, glenohumeral joint, elbow, ankle, and sacroiliac joint, as well as rotator cuff tendinopathy, lateral and medial epicondylitis, plantar fasciitis, patellar tendinopathy, Achilles tendinopathy, and proximal hamstring tendinopathy.

Investigating the Safety and Regenerative Potential of MSC-Derived Secretome Combined With PRGF in Knee Osteoarthritis

This Phase I/II randomized clinical trial investigates the safety, feasibility, and early regenerative potential of intra-articular administration of mesenchymal stem cell (MSC)-derived secretome combined with Plasma Rich in Growth Factors (PRGF) in patients with knee osteoarthritis (KOA). The study aims to assess whether this cell-free, biologically enriched therapeutic combination can reduce pain, improve joint function, and promote cartilage repair.

Future Osteoarthritis Treatment - Free Open Online Course for All

The basic treatment for osteoarthritis is education and information, often provided as so-called osteoarthritis schools. These can be provided either physically at the health center or digitally. The content is similar in all osteoarthritis schools. It is not clear whether today's osteoarthritis schools contain what people with osteoarthritis are asking for in terms of education and information. The purpose of this project is therefore to highlight what people with osteoarthritis want the osteoarthritis school to contain and whether there is a need for other ways of running osteoarthritis schools than today. Participating in this project means that you will be invited to a focus group with other people who have osteoarthritis. Focus groups will be held at Forum Medicum, Sölvegatan 19 in Lund and will last approximately 1 hour. There will be several different times to choose from. The conversation in the focus group will be recorded. The project will collect and register information about you. We will collect information about gender, age, in which joint(s) the person has osteoarthritis and how long they have had osteoarthritis, as well as whether they have participated in any osteoarthritis school and if so, what form (physical or digital). The recorded conversation from the focus group will be transcribed.

Bone Enhanced Ultrasound (BEUS) Data Library Development Project

A common treatment for low back pain involves fluoroscopy-guided spinal facet joint injections and/or medial branch nerve blocks. Unfortunately, fluoroscopy requires expensive equipment and personnel and exposes patients and healthcare providers to ionizing radiation. Ultrasound offers a safer, lower-cost alternative, but the traditional 2-dimensional (2D) ultrasound systems are limited due to poor image quality, particularly in patients with higher body mass index (BMI). As an alternative, a novel Bone Enhanced Ultrasound (BEUS) technology uses artificial intelligence (AI) to create real-time 3-dimensional (3D) images of the spine to guide needle placement for these injections. The AI software is trained by overlaying computed tomography (CT) and ultrasound images from a patient dataset to recognize anatomical landmarks. BEUS aims to ultimately replace fluoroscopy for spinal injections, reducing radiation exposure, lowering healthcare costs, and improving accessibility, especially in rural settings where CT and fluoroscopy are unavailable. A key limitation, however, is that the current AI system is trained based primarily on patients (mostly pediatric) undergoing perioperative assessment of scoliosis. To address this, the current study aims to develop a new, more clinically relevant training AI dataset by collecting spinal ultrasounds from up to 100 adult participants (most/all of whom are followed at the local chronic pain clinic for low back pain) with existing spinal CT or magnetic resonance imaging (MRI) scans. This dataset will be used to retrain the current AI model to enhance the accuracy of 3D spinal reconstructions, thereby improving the clinical relevance of the BEUS system.
