Abstract：Objective To explore the effect of saphenous nerve block through inferior approach of medial femoris muscle in total knee arthroplasty in advanced age. Methods A total of 104 advanced age patients with total knee arthroplasty admitted to Lishui People’s Hospital, Zhejiang Province from January 2020 to January 2022 were selected, they were divided into study group (52 cases) and control group (52 cases) according to the random number table method. The control group received sciatic nerve block anesthesia through lower outer approach of large rotor, and study group was anesthetized by saphenous nerve block through inferior approach of medial femoris muscle. Surgical indexes and nerve block indexes were compared between two groups; visual analogue scale (VAS) scores of resting and active state were compared between two groups before surgery (T0), 6 h after surgery (T1), 12 h after surgery (T2), 24 h after surgery (T3) and 48 h after surgery (T4); the knee function scores of two groups were compared one and six months after surgery; the occurrence of adverse reactions was observed. Results There were no significant differences in operation time, anesthesia completion time, sensory block onset time, sensory block maintenance time, motor block onset time, motor block maintenance time, and motor block effect score between two groups (P＞0.05); the sensory block effect score in study group was higher than that in control group, and the difference was statistically significant (P＜0.05). At T1, there were no significant differences in resting and active VAS scores between two groups compared with T0 (P＞0.05); at T2-T4, the resting and active VAS scores of two groups were higher than those at T0, and the differences were statistically significant (P＜0.05). At T0-T1, there was no significant differences in resting and active VAS scores between two groups (P＞0.05); At T2-T4, the resting and active VAS scores of study group were lower than those of control group, and the differences were statistically significant (P＜0.05). Six months after surgery, the knee function scores of two groups were higher than those of one month after surgery, and the differences were statistically significant (P＜0.05); one and six months after surgery, there was no significant difference in knee function scores between two groups (P＞0.05). There was no significant difference in the total incidence of adverse reactions between two groups (P＞0.05). Conclusion It is safe and reliable to apply saphenous nerve block through inferior approach of medial femoris muscle in total knee arthroplasty in advanced age, which can enhance analgesic effect and reduce postoperative pain.
