Adductor canal blocks (ACBs) provide effective analgesia following total knee arthroplasty. We hypothesized that ACB single injection plus intravenous (IV) dexamethasone (Dex) shows non-inferiority to catheter, while ACB single injection does not. ⋯ Single injection ACB, with and without IV Dex, is non-inferior to ACB catheters in 24-hour opioid consumption, and may be attractive options for early-discharge, fast-track total knee arthroplasty.

Randomized Controlled Trial
Continuous Adductor Canal Blocks Provide Superior Ambulation and Pain Control Compared to Epidural Analgesia for Primary Knee Arthroplasty: A Randomized, Controlled Trial.
Adductor canal blocks (ACBs) are an alternative to femoral nerve blocks that minimize lower extremity weakness. However, it is unclear whether this block will provide analgesia that is equivalent to techniques, such as epidural analgesia. The purpose of this randomized controlled trial was to compare continuous ACBs with epidural analgesia for primary total knee arthroplasty. ⋯ Continuous adductor analgesia provides superior ambulation, lower pain scores, faster discharge, and greater patient satisfaction when compared to epidural analgesia for primary total knee arthroplasty.

Gait instability and muscle rigidity are known characteristics of Parkinson's disease (PD), putting PD patients at risk for complications following total joint arthroplasty (TJA). The outcomes of Parkinson's patients undergoing TJA are largely unknown. This study evaluated the outcomes of TJA in this population. ⋯ Patients with PD are at increased risk for complications, particularly periprosthetic infection following TKA and periprosthetic fracture and dislocation following THA. Despite this increased risk of complications, patients with PD can demonstrate improved functional outcomes but not as high as patients without PD. Patients with PD should be counseled appropriately prior to undergoing TJA.

The use of intravenous acetaminophen has seen recent enthusiasm as one component of a multimodal approach to pain management. However, there is a lack of literature examining the efficacy of intravenous acetaminophen for pain control in total joint arthroplasty. The purpose of this study was to evaluate the efficacy of intravenous acetaminophen following primary total knee arthroplasty. ⋯ Intravenous acetaminophen is effective in significantly reducing opioid requirements in the first 24 hours following primary total knee arthroplasty. Additionally, there is a clinically significant decrease in VAS pain scores in patients receiving this intervention.
