Osteo Arthritis Knee and Hip

The aim is to evaluate the test-retest reliability of the primary care-adapted Ekblom-Bak submaximal ergometer bicycle test in patients with hip- and/or knee osteoarthritis (OA). Forty patients with hip- and/or knee OA eligible for the Swedish national OA treatment program in primary care are to be recruited. After screening for contraindications, participants will perform the aEB-test twice within 1-2 weeks. The investigators hypothezise that the test will demonstrate acceptable test-retest reliability in patients with hip- and/or knee OA. To establish reliability is essential for future studies using this test in this population and may support its integration into routine clinical assessment.

This study aims to find out which lifestyle approach works best for people with chronic musculoskeletal pain (such as low back pain or hip/knee osteoarthritis) who also have poor sleep. Participants will be randomly assigned to one of three 12-month home-based programs: exercise, cognitive behavioral therapy for insomnia (CBT-I), or a combination of both. Each program includes up to 10 online sessions with a physiotherapist and guidance on managing pain, sleep, and physical activity. We will measure changes in pain, sleep quality, and overall health using questionnaires, wearable devices, sensory tests, and blood samples. The goal is to improve understanding of non-medication treatments for pain and sleep problems.

This study aims to learn how symptoms and daily functioning change over time in people with hip or knee osteoarthritis (OA). The goal is to use this information to build computer models that can predict these changes. In the future, these models may help give people with OA the right self-care advice at the right time through a web application called ArtroseCoach. People with OA will take part in this study for one year. Every two weeks, they will fill in online questionnaires covering various aspects of their health and daily functioning, such as pain, daily activities, and participation in life. During the year, participants will be randomly assigned to one of several self-care programs in the ArtroseCoach web app. These programs focus on physical activity, weight management, or sleep. Each program lasts 12 weeks. At four points during the year (weeks 3, 15, 27, and 39), participants will receive one of these programs or no program at all. No one will receive the same program twice. The ArtroseCoach web app provides education about OA, lifestyle advice, and tips to support behavior change. The study will help researchers understand which factors are linked to changes in pain and physical functioning over time. This knowledge will be used to improve the ArtroseCoach and other future tools that support people with OA in managing their condition on their own.

Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are common operations used to treat severe joint disease, most often caused by osteoarthritis. An increasing number of these procedures are now performed as outpatient surgery, meaning that patients can go home on the same day as the operation. This can be beneficial for both patients and healthcare systems, but it requires safe and efficient anaesthetic care. Two different types of anaesthesia are commonly used for these operations: general anaesthesia (where the patient is asleep) and spinal anaesthesia (where the lower part of the body is numbed). Both methods are well established and widely used. Previous studies suggest that the choice of anaesthesia may affect how quickly patients recover, how comfortable they feel after surgery, and whether they can be safely discharged on the day of surgery. However, most existing studies are based on retrospective data, and there is limited randomized evidence comparing these anaesthetic techniques in the outpatient setting. The GASPS trial is a multicentre, randomized, phase IV clinical study that compares general anaesthesia and spinal anaesthesia in adults undergoing outpatient primary total knee or hip arthroplasty. A total of 600 participants will be included and randomly assigned to receive one of the two anaesthetic methods on the day of surgery. All participants will receive standard surgical and perioperative care, and both anaesthetic techniques are part of routine clinical practice. The main aim of the study is to investigate whether the type of anaesthesia influences the chance of successful same-day discharge, defined as going home on the day of surgery without needing to be readmitted within 48 hours. The study will also examine recovery time, pain, nausea and vomiting, use of pain medication, complications, patient-reported recovery and function, and healthcare costs. In addition, patient experiences of anaesthesia and postoperative recovery will be explored through interviews in a smaller group of participants. Participants will be followed using questionnaires and medical records from the day of surgery up to 12 months after the operation. The results of this study are expected to provide clear and reliable information to help guide anaesthetic care for patients undergoing outpatient hip and knee replacement surgery.
