1. FTB and ACB showed similar resting and activity pain scores, but FTB had better analgesic efficacy at 48 hours postoperatively.
2. ACB better preserved quadriceps muscle strength, whereas one study suggested FTB had advantages in quadriceps strength recovery.
3. No significant differences were observed regarding postoperative adverse reaction incidence rates and patient satisfaction scores.
4. The study recommends further large-scale, high-quality RCTs due to study limitations and differences in enrolled articles.
5. The anatomical differences contribute to differential effects of FTB and ACB on analgesia and muscle function.
