NCT05152758
Anterior cruciate ligament (ACL) ruptures are very common knee injuries amongst youth involved in sports and are often treated through ACL reconstruction surgeries. Unfortunately, up to 50% of individuals who undergo ACL reconstruction develop post-traumatic osteoarthritis (PTOA) in their injured knee by 20 years post-reconstruction causing pain, decreasing mobility, and impacting quality of life in young active individuals. Much remains unknown regarding the secondary prevention of PTOA, and more investigation is necessary to better understand its disease progression post-ACL reconstruction and types of conservative interventions that can prevent or delay its onset. Physical activity has improved patient-reported outcomes across many different chronic diseases including knee osteoarthritis (OA), and physical activity prescription has been shown to be an effective way to increase patients' levels of physical activity. It has not yet been heavily investigated in the context of post-ACL reconstruction, and individuals often exhibit decreased physical activity after ACL reconstruction which causes suboptimal cartilage health. Thus, physical activity prescription may improve habitual joint loading, leading to improved cartilage health and patient-reported health outcomes.

Immobilization after radius fracture seems to increase the risk of developing a Complex regional pain syndrome (CRPS), a condition associated with pain, increased skin sensitivity and reduced epidermal nerve density. The purpose of the study is to determine whether 5-week immobilisation leads to functional and structural sensory changes, and whether the changes are associated with persistent pain. The investigators plan an explorative, pilot study on six consenting patients immobilised after a distal radius fracture. The baseline measurements will be recorded at the day of or the day after trauma: Demographics, psychological and physical comorbidity, pain characteristics and intensity, hand function, health related quality of life (HRQOL), quantitative sensory testing will be recorded while skin biopsies are analyzed for epidermal nerve fiber density. Following variables such as pain characteristics and intensity, hand function, health related quality of life, quantitative sensory testing and skin biopsies will be reassessed when the cast is removed and two months later.
