Hospital variation in revision rates after primary knee arthroplasty was not explained by patient selection: baseline data from 1452 patients in the Danish prospective multicenter cohort study, SPARK
To investigate whether hospital variations in patient selection were associated with differences in cumulative revision rates (CRRs) after primary knee arthroplasty (KA) across three Danish regions: Capital Region, Central Denmark Region, and North Denmark Region.
Key Findings:
Significant variation in CRRs was observed across different regions in Denmark, with no clear correlation found based on patient demographics or implant selection.
Patient characteristics and PROMs were systematically collected to assess potential factors influencing revision rates.
Interpretation:
The study highlights the need for further investigation into factors influencing CRR variations beyond patient selection and implant choice, including potential institutional practices and regional healthcare policies.
Limitations:
The study does not yet report postoperative outcomes, which limits the understanding of the impact of the findings.
Potential biases in patient selection and reporting may exist, which could affect the validity of the results.
Conclusion:
Further analysis is required to understand the underlying causes of CRR variations in knee arthroplasty across different hospitals.

A long-term cohort study found that obesity was not associated with worse patient-reported outcomes or higher reoperation rates following total ankle replacement in optimized surgical candidates.
