Swedish Knee Arthroplasty Register is a national clinical registry that records knee arthroplasty procedures across Sweden. The register collects longitudinal data on implants, procedures, and outcomes to support quality improvement, clinical research, and health policy. It informs clinicians, hospitals, and policymakers by producing annual reports, benchmarking performance, and promoting evidence-based practice.
The register was established in 1975 during a period when Scandinavian nations were expanding national quality registries alongside projects in Karolinska Institute, Sahlgrenska University Hospital, Uppsala University Hospital, Lund University, and Göteborg. Early development involved orthopedic surgeons associated with Göteborg University, collaborations with registry experts from Norway and Denmark, and engagement with national health authorities from Stockholm. Over subsequent decades the register evolved with methodological contributions from researchers linked to Harvard Medical School, University of Oxford, and Stanford University visiting collaborations, and with comparative work paralleling registries such as the Norwegian Arthroplasty Register and the Australian Orthopaedic Association National Joint Replacement Registry.
The register’s primary objective is to monitor implant survival and patient outcomes after knee arthroplasty to reduce revision rates and improve patient safety alongside institutions such as Karolinska University Hospital, Sahlgrenska Hospital, and regional health boards in Skåne County. Secondary aims include providing data for epidemiological studies at universities like Uppsala University and Lund University, informing procurement decisions by agencies comparable to Swedish Association of Local Authorities and Regions, and supporting guideline development referenced by professional societies such as the Swedish Orthopaedic Association and international bodies including the International Society of Arthroplasty Registries.
Governance includes a steering committee composed of orthopedic surgeons from centers such as Linköping University Hospital and Örebro University Hospital, researchers affiliated with Karolinska Institute and University of Gothenburg, and representatives from regional healthcare authorities in Västra Götaland County. Data custodianship follows Swedish data protection frameworks involving legal contexts like Swedish Data Protection Authority and national ethics review boards similar to those at Uppsala University Hospital. Operational management interfaces with clinical teams at hospitals including Danderyd Hospital and Malmö University Hospital, and collaborates with academic units at Chalmers University of Technology for registry infrastructure and analysis.
The registry captures perioperative and implant-specific variables reported by surgeons at institutions across Sweden including Stockholm, Gothenburg, and Malmö. Core datasets include implant brand, fixation method, patient demographics, and revision indicators, enabling survival analysis methods taught at universities such as Karolinska Institute and Uppsala University. Data linkage leverages national population registers like the Swedish National Board of Health and Welfare and personal identity number systems used across Swedish agencies, permitting outcome ascertainment and death linkage mirroring practices at Statistics Sweden. Quality assurance entails validation studies undertaken with partners at University of Oxford and statistical support from groups at Imperial College London and University of Cambridge for risk-adjustment and Kaplan–Meier survival estimation.
Analyses from the register have identified prosthesis-specific failure patterns, influenced implant selection at hospitals including Sahlgrenska University Hospital and procurement policies in Skåne County Council. Reported reductions in revision rates have been cited in clinical guidelines produced by organizations such as the Swedish Knee Arthroplasty Working Group and informed device regulatory discussions involving agencies analogous to the European Medicines Agency and health technology assessment bodies connected with National Institute for Health and Care Excellence. Comparative studies with the Norwegian Arthroplasty Register and the Finnish Arthroplasty Register have shaped implant surveillance internationally and contributed to safer surgical practice in centers at Harvard Medical School and Mayo Clinic.
The register underpins peer-reviewed publications in journals frequented by researchers at The Lancet, BMJ, Journal of Bone and Joint Surgery, and Acta Orthopaedica. Collaborative studies involve investigators from Karolinska Institute, University of Oxford, Stanford University School of Medicine, and McMaster University, addressing topics from prosthesis longevity to perioperative risk stratification. Methodological papers draw on biostatistics groups at University of Cambridge and Imperial College London, and registry findings have been cited in textbooks used at Uppsala University and training curricula of the Swedish Orthopaedic Association.
The register participates in multinational initiatives with the International Society of Arthroplasty Registries, comparative projects with the Australian Orthopaedic Association National Joint Replacement Registry, and data harmonization efforts with the European Arthroplasty Registry Network. Its models for continuous quality improvement have been referenced by health systems at NHS England, academic centers like Johns Hopkins Hospital, and regulatory frameworks influenced by the European Commission. Ongoing exchanges with registries in Norway, Denmark, Finland, and networks linked to World Health Organization efforts on patient safety continue to expand its international influence.
