Halder AM, Gehrke T, Günster C, et al. - Using nationwide healthcare insurance data for inpatient hospital treatment, 23,644 aseptic revision (R)-TKAs in 21,573 individuals treated between January 2013 and December 2017 were examined in order to assess the association between hospital volume and re-revision rate after R-TKA. On the 1-year re-revision rate, hospital volume had an important impact. The 90-day mortality and major in-house adverse events declined with rising volume, however, following risk adjustment, this was not statistically important. In summary, evidence of greater risk for re-revision surgery in hospitals with fewer than 25 R-TKA per year was discovered. Moreover, it may add to improved patient care if complex elective procedures like R-TKA which need experience and a specific logistic background were done in specialized centers.
