Year | Author | Type of study | Sample size | Method | Results |
|---|---|---|---|---|---|
2019 | Aso et al. (2019) | A prospective single-center double-blind, randomized controlled trial | 40 | PAI with a femoral nerve block (FNB) vs FNB alone | PAI with FNB was more effective in reducing pain after TKA (p < 0.05) |
2018 | Fenton et al. (2018) | A prospective single-center double-blind, randomized controlled trial | 80 | PAI vs PAI with FNB catheter | PAI with FNB was more effective in reducing pain after TKA (p < 0.005) |
2020 | Kampitak et al. (2020) | A prospective single-center double-blind, randomized controlled trial | 90 | PAI with continuous adductor canal block with (1) obturator nerve block vs (2) tibial nerve block vs (3) obturator and tibial nerve block | PAI with triple nerve block was more effective in reducing pain after TKA (p < 0.05) |
2018 | Biswas et al. (2018) | A prospective single-center double-blind, randomized controlled trial | 201 | PAI with sham adductor canal block (ACB) vs PAI with adductor canal block vs PAI with intrathecal morphine | PAI with ACB was more effective in reducing pain after TKA (p = 0.007) |
2022 | Luo et al. (2022) | A prospective single-center, double-blind, randomized controlled trial | 86 | PAI vs PAI with ACB | PAI with ACB was more effective in reducing pain after TKA (p < 0.05) |
2018 | Tziona et al. (2018) | A prospective single-center, double-blind, randomized controlled trial | 40 | PAI vs PAI with ACB | PAI with ACB was more effective in reducing morphine consumption (p < 0.05) |
2019 | Lan et al. (2019) | Double-blind, randomized, placebo-controlled trial | 46 | PAI vs PAI with CACB | PAI with CACB was more effective in reducing pain after TKA (p < 0.001) |
2017 | Gudmundsdottir et al. (2017) | Randomized, double-blind, placebo-controlled trial | 69 | PAI vs PAI with CACB | CACB added to PAI showed no benefit |
