INTRODUCTION: fast-track protocols in total hip and knee arthroplasty (THA/TKA) have improved postoperative recovery and reduced postoperative morbidity. Additionally, increasing life expectancy and improved surgical techniques have led to an increasing number of older adult patients undergoing THA/TKA. However, no large detailed studies on fast-track THA/TKA in older adults are available. Consequently, we aimed to describe the length of stay (LOS) and postoperative morbidity in a large cohort of patients ≥85 years within a continuous multicentre fast-track collaboration.

METHODS: we used a prospective observational cohort design with unselected consecutive data between 2010 and 2017 on primary elective THA and TKA patients ≥85 years. Data were obtained from nine centres reporting to the Lundbeck Foundation Centre for Fast-track Hip and Knee Replacement database and the Danish National Patient Registry on LOS, readmissions and mortality. Causes of morbidity were determined by review of health records.

RESULTS: we included 1,427 (3.9% of all THA/TKA) procedures with 62.3% THA. Median age was 87 (IQR: 85-88) years with 71% women. LOS decreased from median 4 (3-6) days in 2010 to 2 (2-3) days in 2017. The proportion with LOS > 4 days decreased from 32 to 18%. Readmission and mortality rate remained at about 11.7 and 0.9% after 30 days and 16.0 and 1.5% after 90 days, respectively.

CONCLUSION: this detailed large multicentre fast-track THA/TKA study in patients ≥85 years found major reductions in LOS without increase in readmission or mortality rates. The unchanged readmission rate poses an area for further improvements.
