The Faroese Knee Cohort Study on Causes and Long-Term Effects of Patellar Dislocation, Trochlear Dysplasia, and Knee Injuries in Ages 15 to 20

What this Trial Is About

Researchers are establishing the Faroese Knee Cohort to include all individuals aged 15 to 20 years from the Faroe Islands who have patellar instability or a prior knee injury such as ACL rupture or meniscus damage. The study focuses on understanding patellar dislocations, trochlear dysplasia, and their long-term effects, including the development of retropatellar arthritis and impacts on quality of life and function. It also investigates the prevalence and outcomes of ACL and meniscus injuries in this population. This observational study does not involve any intervention. Participants are grouped based on their knee condition those with patellar dislocation without trochlear dysplasia, those with patellar dislocation and trochlear dysplasia, and those with ACL or meniscus injuries. These diagnoses are determined using MRI or X-ray imaging, and the study examines various knee measurements and behavioral risk factors such as participation in pivoting sports. Participants will be followed and assessed for the severity and frequency of patellar dislocations or near-dislocations over one year. Researchers will collect patient-reported outcomes related to activity levels, luxation scores, and patellofemoral pain. The study includes clinical evaluations, imaging, and questionnaires to understand risk factors and long-term effects on knee function and quality of life, with a planned observation period extending to 2051.
