Review Meta Analysis Comparative Study
Is Adductor Canal Block Better Than Femoral Nerve Block in Primary Total Knee Arthroplasty? A GRADE Analysis of the Evidence Through a Systematic Review and Meta-Analysis.
Total knee arthroplasty (TKA) is associated with intense postoperative pain with a need for early ambulation to gain function and prevent postoperative complications. Compared with femoral nerve block (FNB), adductor canal block (ACB) can relieve postoperative pain and preserve quadriceps muscle strength. This meta-analysis was conducted to investigate which analgesic method provides better pain relief and functional recovery after TKA. ⋯ Compared with FNB, ACB shows similar pain control after TKA. However, ACB can better preserve quadriceps muscle strength and improve mobilization ability. In conclusion, ACB showed better functional recovery after TKA without compromising pain control. Therefore, ACB is recommended as an alternative analgesic method for early ambulation after TKA.

As health care reform drives providers to reduce costs and improve efficiencies without compromising patient care, preoperative planning has become imperative. The purpose of this study is to determine whether height, weight, and gender can accurately predict total knee arthroplasty (TKA) sizing. ⋯ This novel TKA templating model allows final implants to be predicted to within 1 size. The model allows for simplified preoperative planning and potential implementation into a cost-savings program that limits inventory and trays required for each case.

Hip dislocation is one of the most common postoperative complications after total hip arthroplasty (THA). Potential contributors include patient- and surgical-related factors. We performed a retrospective cohort study to identify risk factors for postoperative dislocation in patients receiving THA via the posterolateral approach. ⋯ Surgeons should aim for a shortening of leg length <5 mm to reduce the risk of postoperative dislocation in primary THA. Although anteversion was reduced for dislocating THA, there is likely no universal safe zone for cup positioning. Hip stability is multifactorial, and optimal cup positioning may vary from patient to patient.

Randomized Controlled Trial Comparative Study
Intravenous vs Oral Acetaminophen as an Adjunct to Multimodal Analgesia After Total Knee Arthroplasty: A Prospective, Randomized, Double-Blind Clinical Trial.
The efficacy of intravenous (IV) acetaminophen compared with its oral formulation for postoperative analgesia is unknown. We hypothesized that the addition of acetaminophen to a multimodal analgesia regimen would provide improved pain management in patients after total knee arthroplasty (TKA) and that the effect of acetaminophen would be variable based on the route of delivery. ⋯ Neither IV nor oral acetaminophen provides additional analgesia in the immediate postoperative period when administered as an adjunct to multimodal analgesia in patients undergoing TKA in the setting of a spinal anesthetic.

Comparative Study
Outpatient and Inpatient Unicompartmental Knee Arthroplasty Procedures Have Similar Short-Term Complication Profiles.
Advances in surgical techniques and anesthesia have made performing unicompartmental knee arthroplasty (UKA) in the outpatient setting a possibility. The touted benefits of outpatient surgery include higher patient satisfaction and reduced costs. However, detailed information on the perioperative outcomes of outpatient compared with inpatient UKA in a large, national patient population in the United States has never been reported. The present study compares perioperative complications between outpatient and inpatient UKAs in the National Surgical Quality Improvement Program database. ⋯ Based on the perioperative outcome measures assessed in this study, outpatient UKA can be appropriately considered in carefully selected patients based on the lack of differences in rates of 30-day perioperative complications and readmissions between the outpatient and matched inpatient groups.
