The Danish Knee Arthroplasty Register (DKR) is a national clinical quality database which fx covers side of operation, revision arthroplasty, previous operation on the same knee, functional level, knee score, femur/tibia/patella component, fixing method and type of cement.

One of the main aims of DKR is to identify predictors for the outcomes of knee prosthesis operations so as to improve the treatment to patients and reduce the number of complications and revisions.

DKR was sstablished in 1997. The population is all primary knee arthroplasty and revisions and follow-up examinations at one of the six orthopaedic departments in Denmark undertaking this type of operation, including private hospitals. Data from reporting departments is entered via KMS (Clinical Measurement System) and cross-batched with the National Patient Register (LPR).

The Regional Clinical Quality Databases

Data about clinical quality are collected with the purpose of monitoring and raising the quality of patient treatment in the Danish health-care system. These data can, as well as all other public registers, be made accessible for research projects based on systematic protocols and approved according to the relevant legislations.

Applying for access to data from a regional clinical database requires a list of demands to be obtained. A project description should be attached containing a description of the project explaining the rationale, purpose, methods, budget, publication plan etc.

Furthermore, The Danish Data Protection Agency must approve the project.

Application process

  • Apply via research access (Danish: forskeradgang), an online application system
  • Submit the protocol to The Danish Clinical Registries (RKKP)
  • RKKP registers the application
  • The application is forwarded to the relevant clinical database
  • Potential dialog about adjustment to the protocol
