Thirty adolescent athletes (ages 14-18) who underwent ACLR were randomly allocated to either the control group receiving traditional postoperative rehabilitation (n = 15) or the intervention group combining BOSU ball training with resistance exercises (n = 15).

The intervention group demonstrated notably better anterior-posterior knee joint stability (P < .05) than the control group at the 6-month and 12-month follow-ups after the surgery, greater reach distances in the Star Excursion Balance Test (P < .05), higher quadriceps and hamstring strength ratios (P < .05), and superior ACL-RSI scores (P < .01).
