Article entitled ¿hospital frailty risk score predicts adverse events in primary total hip and knee arthroplasty" written by matthias meyer, md, lukas parik, md, franziska leiss, md, and tobias renkawitz, md published by the journal of arthroplasty accepted on june 30, 2020 was reviewed.The articles purpose was to determine the utility of the hfrs as a predictor for postoperative adverse events after primary total hip (tha) and knee (tka) arthroplasty.4558 thas and 3692 tkas were performed at a high volume arthroplasty center.Press-fit acetabular components and cement-free stems of one single manufacturer (pinnacle cup, corail, or trilock stem; depuy, warsaw, in) were used in all thas.Cemented tka was performed through a medial parapatellar approach.Cemented components of one single manufacturer (pfc sigma; depuy) were used in all tkas.No patella resurfacing was performed.A retrospective analysis between 2011 and 2019 of the hfrs was calculated for each patient.Reoperation rates, readmission rates, complication rates, and transfusion rates were compared between patients with low and intermediate or high frailty risk.The study determined that hfrs predicts adverse events after tha and tka and therefore allows hospitals to identify at-risk patients without extra effort or expense.Findings: adverse events after tha: 198 patients required reoperation within 90 days 177 patients required readmission to the hospital within 90 days 57 patients diagnosed with a periprosthetic fracture 22 patients diagnosed with luxation 38 patients diagnosed with a wound healing disorder 5 patients diagnosed with a joint infection 3 patients diagnosed with acute coronary syndrome 9 patients diagnosed with decompensated heart failure 21 patients diagnosed with cardiac arrythmia 24 patients diagnosed with acute renal failure 11 patients diagnosed with thrombosis 7 patients diagnosed with pulmonary embolism 33 patients diagnosed with collapse 4 patients diagnosed with cerebrovascular accident 68 patients diagnosed with postoperative delirium 71 patients diagnosed with clavien-dindo iv 82 patients required a transfusion adverse events after tka: 169 patients required reoperation within 90 days 196 patients required readmission to the hospital within 90 days 14 patients diagnosed with a periprosthetic fracture 12 patients diagnosed with insufficient range of motion 33 patients diagnosed with a wound healing disorder 2 patients diagnosed with a joint infection 4 patients diagnosed with acute coronary syndrome 2 patients diagnosed with decompensated heart failure 15 patients diagnosed with cardiac arrythmia 24 patients diagnosed with acute renal failure 14 patients diagnosed with thrombosis 8 patients diagnosed with pulmonary embolism 47 patients diagnosed with collapse 7 patients diagnosed with cerebrovascular accident 55 patients diagnosed with postoperative delirium 60 patients diagnosed with clavien-dindo iv 59 patients required a transfusion depuy products: -unknown acetabular cup pinnacle -unknown acetabular liner -unknown femoral head -unknown femoral stem corail -unknown femoral stem trilock -unknown knee femoral sigma -unknown knee tibial insert sigma -unknown knee tibial tray sigma.
