ACL reconstruction patients have increased risk of knee arthroplasty at 15 years of follow-up: Data from the Norwegian Knee Ligament Register and the Norwegian Arthroplasty Register from 2004 to 2020
Visnes, Håvard; Gifstad, Tone; Persson, Andreas; Lygre, Stein Håkon Låstad; Engebretsen, Lars; Drogset, Jon Olav; Furnes, Ove Nord (Peer reviewed; Journal article, 2022)Background: Anterior cruciate ligament (ACL) injury is considered a risk factor for osteoarthritis. The primary aim of the present study was to investigate the cumulative risk of, and risk factors associated with, a ... -
Ceiling Effect of the Combined Norwegian and Danish Knee Ligament Registers Limits Anterior Cruciate Ligament Reconstruction Outcome Prediction
Martin, R. Kyle; Wastvedt, Solvejg; Pareek, Ayoosh; Persson, Andreas; Visnes, Håvard; Fenstad, Anne Marie; Moatshe, Gilbert; Wolfson, Julian; Lind, Martin; Engebretsen, Lars (Peer reviewed; Journal article, 2023)Background: Clinical tools based on machine learning analysis now exist for outcome prediction after primary anterior cruciate ligament reconstruction (ACLR). Relying partly on data volume, the general principle is that ... -
Genetic variation in candidate genes and patellar tendinopathy: Prospective cohort study of 126 elite volleyball players
Haug, Kari Bente Foss; Visnes, Håvard; Sivertsen, Einar; Bahr, Roald (Journal article; Peer reviewed, 2018)Variation in genes coding for structural proteins may represent risk factors for developing tendinopathy among athletes. The purpose of this prospective cohort study of elite volleyball students was to investigate whether ... -
Good validity in the Norwegian Knee Ligament Register: Assessment of data quality for key variables in primary and revision cruciate ligament reconstructions from 2004 to 2013
Midttun, Espen; Andersen, Morten Torheim; Engebretsen, Lars; Visnes, Håvard; Fenstad, Anne Marie; Gjertsen, Jan-Erik; Persson, Andreas (Peer reviewed; Journal article, 2022)Background: The Norwegian Knee Ligament Register was founded in 2004 to provide representative and reliable data on cruciate ligament surgery. The aim of this study was to evaluate the validity of key variables in the ... -
How to translate and locally adapt a PROM: Assessment of cross‐cultural differential item functioning
Krogsgaard, Michael R.; Brodersen, John; Christensen, Karl B; Siersma, Volkert Dirk; Jensen, Jonas; Hansen, Christian Fugl; Engebretsen, Lars; Visnes, Håvard; Forssblad, Magnus; Comins, Jonathan D. (Peer reviewed; Journal article, 2020)Translating patient‐reported outcome measures (PROMs) can alter the meaning of items and undermine the PROM's psychometric properties (quantified as cross‐cultural differential item functioning [DIF]). The aim of this paper ... -
Jumper's knee paradox—jumping ability is a risk factor for developing jumper's knee: A 5-year prospective study
Visnes, Håvard; Aandahl, Hans Åge; Bahr, Roald (Journal article; Peer reviewed, 2012-10-11)Background The ‘jumper's knee paradox’, where symptomatic athletes appear to perform better in a counter movement jump (CMJ) compared to asymptomatic controls in previous case–control studies is not fully understood. Aim ... -
The long-term risk of knee arthroplasty in patients with arthroscopically verified focal cartilage lesions: A linkage study with the Norwegian Arthroplasty Register, 1999 to 2020
Birkenes, Thomas; Furnes, Ove Nord; Lygre, Stein Håkon Låstad; Solheim, Eirik Johan; Årøen, Asbjørn; Knutsen, Gunnar; Drogset, Jon Olav; Heir, Stig; Engebretsen, Lars; Løken, Sverre Bertrand; Visnes, Håvard (Peer reviewed; Journal article, 2023)Background: Focal cartilage lesions are common in the knee. The risk of later ipsilateral knee arthroplasty remains unknown. The purposes of the present study were to evaluate the long-term cumulative risk of knee arthroplasty ... -
Machine learning algorithm to predict anterior cruciate ligament revision demonstrates external validity
Martin, Richard Kyle; Wastvedt, Solvejg; Pareek, Ayoosh; Persson, Andreas; Visnes, Håvard; Fenstad, Anne Marie; Moatshe, Gilbert; Wolfson, Julian; Lind, Martin; Engebretsen, Lars (Peer reviewed; Journal article, 2022)Purpose: External validation of machine learning predictive models is achieved through evaluation of model performance on different groups of patients than were used for algorithm development. This important step is ... -
Major increase in incidence of pediatric ACL reconstructions from 2005 to 2021: A study from the Norwegian Knee Ligament Register
Tveiten, Caroline Emilie Van Woensel Kooy; Jakobsen, Rune Bruhn; Fenstad, Anne Marie; Persson, Andreas; Visnes, Håvard; Engebretsen, Lars; Ekås, Guri Ranum (Peer reviewed; Journal article, 2023)Background: The incidence of pediatric and adolescent anterior cruciate ligament reconstruction (ACLR) is increasing in several countries.
