BiFeS vs. iPACK in Postoperative Knee Arthroplasty Analgesia

The Biceps Femoris Short Head (BiFeS) block is a new fascial plane block technique targeting the sensory innervation of the posterolateral capsule of the knee while preserving motor function. The aim of this study is to evaluate the postoperative analgesic efficacy of the BiFeS block combined with the adductor canal block (ACB) in patients undergoing total knee arthroplasty, compared to ACB + iPACK block. The study is planned as a prospective, randomized, double-blind, parallel two-group trial. Patients will be randomized in a 1:1 ratio to receive ACB + iPACK (Group A) or ACB + BiFeS (Group B). Postoperative pain scores (VAS), opioid consumption, early mobilization, and quality of recovery (QoR-15) outcomes will be compared.

FAB Block vs. Placebo for Hip Arthroplasty Patients

Hip arthroplasty surgery can be associated with significant pain. A regional anesthesia technique, the femoral articular branch block (FAB), has recently been proposed to collectively block terminal femoral and accessory obturator nerve branches to the hip joint with a single injection, theoretically blocking most of the innervation relevant to hip arthroscopy while sparing the main femoral nerve branches to the quadriceps muscles. The investigators aim to demonstrate the analgesic benefits of FAB. The investigators hypothesize that FAB will reduce opioid consumption and improve postoperative quality of recovery in patients having hip arthroplasty. This is a randomized, controlled, double-blind study and half the patients will be randomized to receive the femoral articular branch block and the other half of patients will be randomized to receive a placebo block. A comparison of pain will be made between both groups.

Continuous Adductor Canal Block in Outpatient Total Knee Arthroplasty

Total knee arthroplasty (TKA) is a frequent performed surgery. Many institutions are implementing outpatient programs for this surgery and adequate pain management is an important feature. Analgesic duration of single shot nerve blocks is limited to no more than 24h. Conversely, the use of continuous nerve block (CNB) through a perineural catheter and infusion of local anesthetic may increase duration of analgesia and provide better outcomes. The purpose of this study is to evaluate effectiveness and safety of using CNB in patients undergoing primary TKA, and its effects on patients' quality of recovery. We hypothesize that continuous adductor canal block would lead to a better quality of recovery in patients undergoing primary TKA.
