Coverage and accuracy of diagnosis of cruciate ligament injury in the Finnish National Hospital Discharge Register.

Introduction: Routinely collected hospital discharge data are a valuable and widely used source of information when assessing the incidence of sports and other injuries in epidemiological studies. However, in order to ensure the usefulness of a hospital discharge register for scientific purposes, the coverage and accuracy of the database should be evaluated. In this study, cruciate ligament rupture was used to assess the coverage and accuracy of the Finnish National Hospital Discharge Register (NHDR).

Incidence and risk factors of acute traumatic primary patellar dislocation.

Purpose: The purpose of this study was to investigate incidence, nature, and risk factors of primary traumatic patellar dislocations.

Methods: We identified acute first-time traumatic patellar dislocations from a national hospital discharge register. Patients with previous patellar dislocations, subluxations, or knee traumas were excluded.
