Are outcomes after total knee arthroplasty worsening over time? A time-trends study of activity limitation and pain outcomes.
The authors examined whether function and pain outcomes of patients undergoing primary total knee arthroplasty (TKA) are changing over time. Using Mayo Clinic Total Joint Registry data, they found that patient-reported function and pain outcomes after primary TKA have worsened over the study period 1993-95 to 2002-05; this time-trend is independent of changes in preoperative pain/limitation and certain patient characteristics.

Chronic opioid use emerging after bariatric surgery.
The purpose of this study was to determine opioid use the year after bariatric surgery among patients who did not use opioids chronically pre-surgery and to identify pre-surgery characteristics associated with chronic opioid use after surgery. It found that patients dispensed 60 to 119 days’ supply during the pre-surgery year were 13.23 to 14.29 times more likely to use opioids chronically post-surgery than patients without opioid use pre-surgery.

Adductor canal block versus femoral nerve block for total knee arthroplasty: a prospective, randomized, controlled trial.
In a study of pain relief for patients recovering from a total knee arthroplasty, researchers found that adductor canal block (ACB) results in less motor impairment for quadriceps muscles after surgery than femoral nerve block (FNB) and it provides a comparable level of pain relief. The prospective, randomized, controlled study included 46 patients receiving ACB and 47 receiving FNB.
