Does choice of bearings influence the survival of cement-less total hip arthroplasty in patients aged 20–55 years? Comparison of 21,594 patients reported to the Nordic Arthroplasty Register Association dataset 2005–2017
Mikkelsen, Rasmus Tyrsted; Overgaard, Søren; Pedersen, Alma B.; Kärrholm, Johan; Rolfson, Ola; Fenstad, Anne Marie; Furnes, Ove Nord; Hallan, Geir; Mäkelä, Keijo; Eskelinen, Antti; Varnum, Claus (Journal article; Peer reviewed, 2023)Background and purpose: The bearings with the best survivorship for young patients with total hip arthroplasty (THA) should be identified. We compared hazard ratios (HR) of revision of primary stemmed cementless THAs with ... -
Impact of hip arthroplasty registers on orthopaedic practice and perspectives for the future
Varnum, Claus; Pedersen, Alma Bečić; Rolfson, Ola; Rogmark, Cecilia; Furnes, Ove; Hallan, Geir; Mäkelä, Keijo; de Steiger, Richard; Porter, Martyn; Overgaard, Søren (Peer reviewed; Journal article, 2019)Total hip arthroplasty (THA) registers are established in several countries to collect data aiming to improve the results after THA. Monitoring of adverse outcomes after THA has focused mainly on revision surgery, but ... -
Increasing risk of revision due to infection after primary total hip arthroplasty: results from the Nordic Arthroplasty Register Association
Dale, Håvard; Fenstad, Anne Marie; Hallan, Geir; Overgaard, Søren; Pedersen, Alma B.; Hailer, Nils P.; Kärrholm, Johan; Rolfson, Ola; Eskelinen, Antti; Mäkelä, Keijo T.; Furnes, Ove Nord (Journal article; Peer reviewed, 2023)Background and purpose: The incidence of periprosthetic joint infection after total hip arthroplasty (THA) may be increasing. We performed time-trend analyses of risk, rates, and timing of revision due to infection after ... -
International variation in distribution of ASA class in patients undergoing total hip arthroplasty and its influence on mortality: data from an international consortium of arthroplasty registries
Silman, Alan; Combescure, Christophe; Ferguson, Rory J; Graves, Stephen E.; Paxton, Elizabeth W; Frampton, Chris; Furnes, Ove Nord; Fenstad, Anne Marie; Hooper, Gary; Garland, Anne; Spekenbrink-Spooren, Anneke; Wilkinson, J. Mark; Mäkelä, Keijo; Lübbeke, Anne; Rolfson, Ola (Journal article; Peer reviewed, 2021)Background and purpose — A challenge comparing outcomes from total hip arthroplasty between countries is variation in preoperative characteristics, particularly comorbidity. Therefore, we investigated between-country ... -
Similar early mortality risk after cemented compared with cementless total hip arthroplasty for primary osteoarthritis: data from 188,606 surgeries in the Nordic Arthroplasty Register Association database
Pedersen, Alma B.; Mailhac, Aurélie; Garland, Anne; Overgaard, Søren; Furnes, Ove; Lie, Stein Atle; Fenstad, Anne Marie; Rogmark, Cecilia; Kärrholm, Johan; Rolfson, Ola; Haapakoski, Jaason; Eskelinen, Antti; Mäkelä, Keijo; Hailer, Nils P. (Journal article; Peer reviewed, 2021)Background and purpose — Current literature indicates no difference in 90-day mortality after cemented compared with cementless total hip arthroplasty (THA). However, previous studies are hampered by potential selection ... -
Total hip arthroplasties in the Dutch Arthroplasty Register (LROI) and the Nordic Arthroplasty Register Association (NARA): comparison of patient and procedure characteristics in 475,685 cases
Van Steenbergen, Liza N.; Mäkelä, Keijo; Kärrholm, Johan; Rolfson, Ola; Overgaard, Søren; Furnes, Ove; Pedersen, Alma B.; Eskelinen, Antti; Hallan, Geir; Schreurs, Berend W.; Nelissen, Rob G.H.H. (Journal article; Peer reviewed, 2021)Background and purpose — Collaborations between arthroplasty registries are important in order to create the possibility of detecting inferior implants early and improve our understanding of differences between nations in ... -
