Study Summary

Seven randomized controlled trials including 267 patients who had undergone anterior cruciate ligament reconstruction were included in this systematic review and meta-analysis comparing plyometric training rehabilitation versus conventional postoperative rehabilitation. Pooled outcomes of interest included subjective functional scores (IKDC, Lysholm, KOOS), limb symmetry index (LSI), quadriceps peak torque strength, and dynamic balance performance. Overall, plyometric training demonstrated improvements in function, quadriceps strength and modest gains in limb symmetry, while results for dynamic balance were inconsistent across studies. The findings suggest that plyometric training may enhance specific neuromuscular recovery parameters following ACL reconstruction, although the magnitude and consistency of benefit vary depending on outcome measures and patient characteristics.
