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 ... -
Incidence and risk factors of intraoperative periprosthetic femoral fractures during primary total hip arthroplasty: 218,423 cases reported to the Norwegian Arthroplasty Register between 1987 and 2020
Brüggemann, Heinrich; Dalen, Ingvild; Bache-Mathiesen, Lena Kristin; Fenstad, Anne Marie; Hallan, Geir; Fosse, Lars (Peer reviewed; Journal article, 2022)Background and purpose: Intraoperative periprosthetic femoral fractures (IPFFs) can occur during primary total hip arthroplasty (THA). We describe the incidence of IPFFs during THA in Norway and estimate potential risk ... -
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 ... -
Musculoskeletal pain is not clearly associated with the risk of anterior cruciate ligament reconstruction in adolescents
Strømme, Sofie Hammernes; Guddal, Maren Hjelle; Fenstad, Anne Marie; Visnes, Håvard; Zwart, John Anker Henrik; Storheim, Kjersti; Johnsen, Marianne Bakke (Peer reviewed; Journal article, 2023)Objectives: The purpose of this study was to investigate whether self-reported musculoskeletal pain (MSP) was associated with a future anterior cruciate ligament reconstruction (ACLR). Methods: In this population-based ... -
Predicting anterior cruciate ligament reconstruction revision: A machine learning analysis utilizing the Norwegian knee ligament register
Martin, Richard Kyle; Wastvedt, Solvejg; Pareek, Ayoosh; Persson, Andreas; Visnes, Håvard; Fenstad, Anne Marie; Moatshe, Gilbert; Wolfson, Julian; Engebretsen, Lars (Peer reviewed; Journal article, 2022)Background: Several factors are associated with an increased risk of anterior cruciate ligament (ACL) reconstruction revision. However, the ability to accurately translate these factors into a quantifiable risk of revision ... -
Predicting subjective failure of ACL reconstruction: A machine learning analysis of the Norwegian Knee Ligament Register and patient reported outcomes
Martin, Richard Kyle; Wastvedt, Solvejg; Pareek, Ayoosh; Persson, Andreas; Visnes, Håvard; Fenstad, Anne Marie; Moatshe, Gilbert; Wolfson, Julian; Engebretsen, Lars (Peer reviewed; Journal article, 2022)Objectives: Accurate prediction of outcome following anterior cruciate ligament (ACL) reconstruction is challenging, and machine learning has the potential to improve our predictive capability. The purpose of this study ... -
Rates of subjective failure after both isolated and combined posterior cruciate ligament reconstruction: A study from the Norwegian Knee Ligament Registry 2004-2021
Moatshe, Gilbert; LaPrade, Christopher M.; Fenstad, Anne Marie; Persson, Andreas; LaPrade, Matthew D.; Martin, Richard Kyle; Engebretsen, Lars; LaPrade, Robert (Peer reviewed; Journal article, 2024)Background: Outcomes after posterior cruciate ligament (PCL) reconstruction (PCLR) have been reported to be inferior to those of anterior cruciate ligament reconstruction. Furthermore, combined ligament injuries have been ...
