Year | Author | Type of study | Sample size | Method | Results |
|---|---|---|---|---|---|
2020 | Vichainarong et al. (Vichainarong et al. 2020) | A prospective, randomized, double-blind study | 72 | PAI + CACB vs iPACK + PAI + CACB | iPACK + PAI + CACB does not reduce postoperative opioid consumption (p = 0.08) |
2019 | Kim et al. (Kim et al. 2019) | A triple-blinded, randomized controlled trial | 86 | PAI vs iPACK + ACB + modified PAI | iPACK + ACB + PAI significantly improved analgesia (p = 0.001) and reduced opioid consumption (p = 0.005) |
2021 | Kertkiatkachorn et al. (Kertkiatkachorn et al. 2021) | A prospective, randomized controlled trial | 66 | Continuous ACB + iPACK vs continuous ACB + PAI | ACB with IPACK block provides a non-inferior analgesia |
2021 | Naranjo et al. (2021) | A prospective, randomized controlled trial | 80 | iPACK + ACB vs PAI + ACB | iPACK + ACB was more effective in reducing pain after TKA (p < 0.01) |
