Comparison of postoperative motor ability and postoperative analgesia
SD
When comparing quadriceps strength on the affected side during the same postoperative period, the PENG group exhibited higher strength than the FICB group. Furthermore, the quadriceps strength on the affected side in the FICB group was lower than that of the healthy side in the same group at 24 and 48 h postoperatively, with statistically significant differences (P < 0.05). Additionally, the PENG group had an earlier time of initial ambulation after surgery than the FICB group. The detailed data are shown in Table 
Comparison of motor ability between the two groups after surgeryData are presented as mean ± SD. When comparing the number of effective PCNA presses during the same postoperative period, the PENG group had a lower number than the FICB group. Moreover, the number of rescue analgesia administrations from 0 to 24 h after surgery was lower in the PENG group compared to the FICB group, with a statistically significant difference (P < 0.05). The detailed data are shown in Table 
Comparison of postoperative analgesia between the two groups after surgeryData are presented as mean ± SD or number (times).
