1-year follow-up of 920 hip and knee arthroplasty patients after implementing fast-track: Good outcomes in a Norwegian university hospital
(Journal article; Peer reviewed, 2015)Background — Fast–track has become a well–known concept resulting in improved patient satisfaction and postoperative results. Concerns have been raised about whether increased efficiency could compromise safety, and whether ... -
A 2-year RSA study of the Vanguard CR total knee system: A randomized controlled trial comparing patient-specific positioning guides with conventional technique
(Journal article; Peer reviewed, 2018)Backgound and purpose - There is some concern regarding the revision rate of the Vanguard CR TKA in 1 registry, and the literature is ambiguous about the effi cacy of patient-specifi c positioning guides (PSPGs). The objective ... -
A randomized controlled trial on maximal strength training in 60 patients undergoing total hip arthroplasty: Implementing maximal strength training into clinical practice
(Journal article; Peer reviewed, 2018)Background and purpose — Total hip arthroplasty (THA) patients have reduced muscle strength after rehabilitation. In a previous efficacy trial, 4 weeks’ early supervised maximal strength training (MST) increased muscle ... -
A randomized study on migration of the Spectron EF and the Charnley flanged 40 cemented femoral components using radiostereometric analysis at 2 years
(Journal article; Peer reviewed, 2011)Background and purpose We performed a randomized study to determine the migration patterns of the Spectron EF femoral stem and to compare them with those of the Charnley stem, which is regarded by many as the gold standard ... -
Can we define success criteria for lumbar disc surgery? Estimates for a substantial amount of improvement in core outcome measures
(Journal article; Peer reviewed, 2013)Background and purpose A successful outcome after lumbar discectomy indicates a substantial improvement. To use the cutoffs for minimal clinically important difference (MCID) as success criteria has a large potential bias, ... -
CT-based migration analysis is more precise than radio-stereometric analysis for tibial implants: a phantom study on a porcine cadaver
(Peer reviewed; Journal article, 2023)Background and purpose: Radiostereometric analysis (RSA) is the gold standard for migration analysis, but computed tomography analysis methods (CTRSA) have shown comparable results in other joints. We attempted to validate ... -
Dose reduction does not impact the precision of CT-based RSA in tibial implants: a diagnostic accuracy study on precision in a porcine cadaver
(Peer reviewed; Journal article, 2023)Background and purpose: Radiostereometric analysis (RSA) is the gold standard for evaluation of migration of implants. CT-RSA has been shown to have precision at the level of RSA in hip, shoulder, and knee joint replacements. ... -
The extent of first-time THA revision is not associated with patient-reported outcomes at 1-year follow-up: a study of 426 aseptic revisions
(Peer reviewed; Journal article, 2023)Background and purpose: Studies evaluating pain and patient-reported outcome measures (PROMs) related to type of revision total hip arthroplasty (rTHA) are sparse. Our aim was to compare pain, physical function, quality ... -
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
(Journal article; Peer reviewed, 2017)Background and purpose — A large number of fixation methods of hamstring tendon autograft (HT) are available for anterior cruciate ligament reconstruction (ACLR). Some studies report an association between fixation method ... -
The incidence of late-detected developmental dysplasia of the hip and its functional outcomes: a 17-year cohort study using selective ultrasound screening
(Peer reviewed; Journal article, 2023)Background and purpose: We aimed to establish the incidence of late-detected developmental dysplasia of the hip (DDH) with a selective ultrasound (US) examination over 17 years using the femoral head coverage (FHC) as a ... -
The indication for aseptic revision TKA does not influence 1-year outcomes: an analysis of 178 full TKA revisions from a prospective institutional registry
(Peer reviewed; Journal article, 2022)Background and purpose: Outcomes following revision total knee arthroplasty (TKA) may depend on the indication for revision surgery. We compared pain, patient-reported outcome measures (PROMs), and patient satisfaction ... -
Internal fixation of fragility fractures of the femoral neck

Intraoperatively local infiltration anesthesia in hemiarthroplasty patients reduces the needs of opioids: a randomized, double-blind, placebo-controlled trial with 96 patients in a fast-track hip fracture setting
(Peer reviewed; Journal article, 2022)Background and purpose — Local infiltration analgesia (LIA) is commonly used as a component in multimodal analgesia. Pain management directed towards hip fracture patients operated on with hemiarthroplasty is often based ... -
Less periprosthetic bone loss following the anterolateral approach to the hip compared with the direct lateral approach: A subgroup analysis from a randomized trial in patients with a femoral neck fracture
(Journal article; Peer reviewed, 2018)Background and purpose — The loss of bone mineral in the proximal femur following hip arthroplasty may increase the fracture risk around uncemented stems. We hypothesized that the surgical approach to the hip might influence ... -
Muscular strength after total hip arthroplasty. A prospective comparison of 3 surgical approaches
(Journal article; Peer reviewed, 2015)Background and purpose — Minimizing the decrease in muscular strength after total hip arthroplasty (THA) might allow patients to recover faster. We evaluated muscular strength in patients who were operated on using 3 ... -
