Brief summary

In our clinic, routine suprainguinal fascia iliaca block (SIFIB) has been administered for postoperative analgesia in patients undergoing knee arthroplasty. Recently, we have introduced the IPACK (Infiltration between the Popliteal Artery and Capsule of the Knee) block to this regimen, and the aim of this retrospective study is to determine whether the addition of the IPACK block enhances the quality of analgesia. Knee arthroplasty, also known as knee joint replacement surgery, is a common procedure performed to alleviate pain and improve joint function in patients with knee osteoarthritis or other knee-related conditions. Postoperative pain management is crucial for patient comfort and overall recovery. In this study, we aimed to compare the two techniques mentioned earlier, namely the SIFIB (Suprainguinal Fascia Iliaca Block) and the SIFIB+IPACK, by examining the data of patients who underwent knee arthroplasty under spinal anesthesia at our clinic between January 1, 2023, and September 1, 2023.

Inclusion criteria

* Patients meeting the following criteria and whose postoperative follow-up forms were completed in full were included in the study * Patients underwent total knee arthroplasty (TKA) * ASA class I to III. * operated under spinal anesthesia * patient controlled analjgesia device was used for analgesia

Exclusion criteria

Patients whose data were inaccessible or had incomplete follow-up forms were excluded from the study to ensure the accuracy and reliability of our analysis. * PCA device problems in follow up in 24 hours * anesthesia plans were converted to general anesthesia * spinal anesthesia failure * peripheral blocks used other than protocol

Design outcomes

Primary

Measure	Time frame	Description
Opioid consumption	24 hours	Opioid consumption via PCA device

Secondary

Measure	Time frame	Description
NRS scores	24 hours	NRS scores in different time frames. In a Numerical Rating Scale (NRS), patients are asked to circle the number between 0 and 10, that fits best to their pain intensity. Zero usually represents 'no pain at all' whereas the upper limit represents 'the worst pain ever possible'.
