November 20, Lars-Petter Granan defended his PhD thesis on the development of the world´s first national knee ligament registry in Norway.
With its start in 2004, the PhD thesis of Lars-Petter Granan from the Oslo Sports Trauma Research Center describes the background, design, implementation and the first results from this registry.
Furthermore it outlines how a registry can be used to develop clinically relevant guidelines on timing of primary ACL reconstruction.
In addition, valuable comparisons are done between the NKLR and similar registries in Denmark, Sweden, and the USA (MOON).
It is the main intention of the knee ligament registries to contribute to quality control and improvement of the surgical cruciate ligament procedures. This may be done through establishing evidence based national guidelines and protocols for surgical procedures and rehabilitation.
The NKLR has calculated that if 14 patients—registered in the database—with one specific fixation device show failure, this may be considered a failure of that specific device. This will enable the NKLR to give early warnings on poor procedures and devices, and to identify prognostic factors.
The NKLR has the capacity to define the epidemiology of cruciate ligament surgery, to serve as an early warning system for premature device and procedure failure, and to identify factors that are associated with both good and poor outcomes. On the basis of this evidence, clinical practice can be improved following the best example through feedback to hospitals and surgeons.
Lars Engebretsen was the main supervisor for this project.
