Chen EY, et al. - Via 125,019 patients (age <65 years) who underwent total knee arthroplasty (TKA) and total hip arthroplasty (THA) between 2009 and 2012, the researchers intended to determine the chronic prescription opioid use pre- and post-THA and TKA. One year post-surgery, about 72% of 24,127 patients who were chronic prescription opioid users prior to surgery were no longer chronic users. Also, 4% of the 100,892 patients who were nonconsumers before surgery grew into chronic users within 1-year post-surgery. Marked risk factors of persisting chronic opioid use post-surgery were TKA and hospital stay longer than 3 days, however, age played a jumbled role in foretelling the change of opioid use. Hence, according to the definition of chronic use, a decline from 19% to 9% post- total joint arthroplasty (TJA) in overall chronic opioid use was observed. Furthermore, patients stopped the chronic opioid use after TJA (72%) rather than opting to become the chronic users (4%).
