Demographic and operative data were collected. Isokinetic knee flexion and extension peak torque was assessed bilaterally at 180\u00b0\/s using a standardized dynamometer protocol, and Limb Symmetry Index (LSI) was calculated preoperatively and at 4 months postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Ninety\u2010three patients met the inclusion criteria (mean age, 15.6\u2009\u00b1\u20091.3 years).

The postoperative asymmetry seemed primarily driven by strength gains in the contralateral healthy limb. These findings highlight the importance of not overlooking quadriceps strengthening even when using an HS autograft and support the continued use of this graft choice in adolescents, especially regarding the preservation of flexion strength.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n
