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 ... -
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 ... -
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
Persson, Andreas; Gifstad, Tone; Lind, Martin; Engebretsen, Lars; Fjeldsgaard, Knut; Drogset, Jon Olav; Forssblad, Magnus; Espehaug, Birgitte; Kjellsen, Asle; Fevang, Jonas Meling (Peer reviewed; Journal article, 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 ... -
Injury patterns in posterolateral corner knee injury
Toyooka, Seikai; Persson, Andreas; LaPrade, Robert F.; Engebretsen, Lars; Moatshe, Gilbert (Peer reviewed; Journal article, 2023)Background: Posterolateral corner (PLC) knee injuries associated with different injury mechanisms are not well known. Purpose/Hypothesis: This study sought to assess the patterns of associated injuries in the setting ... -
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. It is uncertain whether this trend applies to countries that traditionally prefer ... -
Predicting anterior cruciate ligament reconstruction revision: A machine learning analysis utilizing the Norwegian knee ligament register
