Study summary

The investigators intend to establish a national cohort including all persons in the ages from 15-20 years old with patellar instability (PI) or a prior knee injury (ACL-ruptur or meniscus damage) . The cohort will be nicknamed "The Faroese Knee Cohort".

The overall aim is to investigate two groups.

1. The patella instability group, in which we intend to investigate the following.

* Prevalence of patellar dislocation and trochlear dysplasia in the Faroe Islands.
* Risk factors for patellar dislocations-
* Heredity of trochlear dysplasia.
* If there is a specific gene responsible for the development of trochlear dysplasia.
* The development of retropatellar artrhosis, its onset and its impact on quality of life and function,
2. Knee injury group (ACL-ruptur or meniscus injury)

* The prevalence of ACL-rupture and/or meniscus injury in this specific group in the Faroe Islands.
* The impact on quality of life and function.

Eligibility

Primary outcome measure(s)

• Severity of patellar dislocations — 1 year
  The severity of PD defined by number of PD or near-dislocations the patient experience (daily, weekly, monthly, yearly).
