Table 2 PAI vs PNB
Year | Author | Type of study | Sample size | Method | Results |
|---|---|---|---|---|---|
2020 | Nicolino et al. (Nicolino et al. 2020) | Controlled, double-blinded, randomized | 70 | LIA with a saphenous nerve block (SNB) vs intra-articular cocktail | LIA with SNB was more effective in reducing pain after TKA (p = 0.001) |
2018 | Tong et al. (Tong et al. 2018) | A prospective single-center, double-blind, randomized controlled trial | 40 | LIA vs adductor canal block (ACB) | ACB was more effective in reducing total morphine consumption in the first 24 (p = 0.004) and 48 h (p = 0.03) |
2018 | Runge et al. (Runge et al. 2018) | A prospective single-center, double-blind, randomized controlled trial | 82 | PAI vs combined obturator nerve and femoral triangle blockade | Combined femoral triangle blockade was more effective in reducing morphine consumption (p < 0.001) |
2019 | Cicekci et al. (Cicekci et al. 2019) | A prospective single-center, double-blind, randomized controlled trial | 79 | PAI vs ACB | ACB was more effective in reducing morphine consumption (p < 0.005) |
2020 | Lützner et al. (Lützner et al. 2020) | Randomized, double-blind, placebo-controlled trial | 140 | Femoral nerve block, continuous sciatic nerve block, and single-shot obturator nerve block vs LIA with a continuous intraarticular catheter with ropivacaine | Femoral nerve block, continuous sciatic nerve block, and single-shot obturator nerve block were more effective in reducing morphine consumption (p < 0.05) |
2019 | Kostelnik et al. (2019) | Two-group randomized, controlled clinical trial | 40 | Single shot sciatic nerve block combined with adductor canal block with a catheter (CACB) vs LIA | Single-shot sciatic nerve block combined with CACB was more effective in reducing morphine consumption (p < 0.01) |
