Fixation, sex, and age: highest risk of revision for uncemented stems in elderly women - data from 66,995 primary total hip arthroplasties in the Norwegian Arthroplasty Register
(Peer reviewed; Journal article, 2020)Background and purpose: There is no consensus on best method of fixation in hip arthroplasty. We investigated different modes of fixation in primary total hip arthroplasty (THA) and the influence of age and sex, to assess ... -
Graft fixation influences revision risk after ACL reconstruction with hamstring tendon autografts : A study of 38,666 patients from the Scandinavian knee ligament registries 2004–2011
(Peer reviewed; Journal article, 2018)Background and purpose — A large number of fi xation methods of hamstring tendon autograft (HT) are available for anterior cruciate ligament reconstruction (ACLR). Some studies report an association between fi xation method ... -
High failure rate after internal fixation and beneficial outcome after arthroplasty in treatment of displaced femoral neck fractures in patients between 55 and 70 years. An observational study of 2,713 patients reported to the Norwegian Hip Fracture Register
(Peer reviewed; Journal article, 2018)Background and purpose — The treatment of patients between 55 and 70 years with displaced intracapsular femoral neck fracture remains controversial. We compared internal fixation (IF), bipolar hemiarthroplasty (HA) and ... -
Higher revision risk for unicompartmental knee arthroplasty in low-volume hospitals
(Peer reviewed; Journal article, 2014)Background and purpose — Some studies have found high complication rates and others have found low complication rates after unicompartmental knee arthroplasty (UKA). We evaluated whether hospital procedure volume influences ... -
Improved survival for anatomic total shoulder prostheses: Results of 4,173 shoulder arthroplasties reported to the Norwegian Arthroplasty Register from 1994 through 2012
(Peer reviewed; Journal article, 2015-07-30)Background and purpose — Previously, implant survival of total shoulder prostheses was reported to be inferior to that of hemiprostheses. However, the use of total prostheses has increased in Norway due to reported good ... -
Increasing risk of prosthetic joint infection after total hip arthroplasty. 2,778 revisions due to infection after 432,168 primary THAs in the Nordic Arthroplasty Register Association (NARA)
(Peer reviewed; Journal article, 2012-10)Background and purpose: The risk of revision due to infection after primary total hip arthroplasty (THA) has been reported to be increasing in Norway. We investigated whether this increase is a common feature in the Nordic ... -
Increasing risk of revision due to deep infection after hip arthroplasty. A study on 97,344 primary total hip replacements in the Norwegian Arthroplasty Register from 1987 to 2007
(Peer reviewed; Journal article, 2009-12)Background and purpose: Over the decades, improvements in surgery and perioperative routines have reduced the incidence of deep infections after total hip arthroplasty (THA). There is, however, some evidence to suggest ... -
