| But first, you need a short introduction to our patient cohort. KLIKK. This is Norway, in the northernmost part of Europe. KLIKK. The Norwegian Arthroplasty Register is situated in Bergen, at the west coast. From here we survey the joint replacement activities in the country. The size of the country is not too small, but its sparsely habitated. There are only about 4.5 million Norwegians (KLIKK) Conviniently, we all have our own and unique national identification number. This number is very helpful in linking primary and revision procedures in the joint replacement registry. Health services (KLIKK) are predominantly public and about 500 orthopaedic surgeons, like this one here, serve the population. |
