iPACK Block vs. Periarticular Infiltration for TKA Pain Control

Condition(s) studied

Study summary

This study aims to retrospectively compare two different multimodal analgesic techniques for pain management after total knee arthroplasty (TKA). The primary purpose is to evaluate whether a combination of two specific nerve blocks administered by an anesthesiologist (Femoral Triangle Block + iPACK block) resulted in superior postoperative pain control compared to a hybrid combination of a nerve block and a local infiltration administered by the surgeon (FTB + Periarticular Infiltration \[PAI\]).

The hypothesis is that the FTB + iPACK combination is associated with a significant reduction in Numeric Rating Scale (NRS) pain scores with movement at 24 hours postoperatively. This is a retrospective, observational cohort study conducted at a single center, involving medical records of patients who underwent primary unilateral TKA. Data from patients who received either FTB + iPACK or FTB + PAI as part of their standard clinical care will be extracted and analyzed retrospectively.

Eligibility

Primary outcome measure(s)

• Postoperative Pain Score with Movement at 24 Hours — 24 and 48. hours postoperatively
  Pain assessed via Numeric Rating Scale (NRS) during active movement (e.g., active knee flexion or straight leg raise). Scale: 0 (no pain) to 10 (worst pain imaginable).
