Extract
The Swedish Knee Arthroplasty Register, a prospective national study of
total knee arthroplasty that was begun in 1975, and the corresponding Swedish
National Hip Register, which was begun in 1979, have had a dramatic impact on
joint arthroplasty in that country and have received increasing attention and
imitation in recent
years1-7.
Sharing registry information with surgeons has been an important factor in
allowing Sweden to have a rate of revision hip replacement of approximately 8%
compared with 18% in the United
States4.
