Twleve adolescent female athletes with prior anterior cruciate ligament reconstruction were individually-matched by age (16.4\u00b10.9 vs. 16.4\u00b11.0\u2009yrs.), body mass index (23.2\u00b12.1 vs. 23.2\u00b12.7\u2009kg\/m2), and sport to 12 female athlete controls. One total-body and 2 lateral-leg dual X-ray absorptiometry scans measured total\/segmental body composition. Isokinetic dynamometry measured knee extensor\/flexor peak torque. Squat jumps on force platforms measured bilateral peak vertical ground reaction force. Paired t-tests assessed lean mass, peak torque, and force between previously-injured athletes\u2019 legs and between previously-injured and control athletes\u2019 legs. Previously-injured athletes\u2019 involved vs. non-involved leg demonstrated lower total (7.13\u00b10.75 vs. 7.43\u00b10.99\u2009kg; p&lt;0.01) and anterior (1.49\u00b10.27 vs. 1.61\u00b10.23\u2009kg; p&lt;0.01) and posterior (1.90\u00b10.19 vs. 2.02\u00b10.21\u2009kg; p=0.04) upper-leg lean mass. Involved leg peak torque (1.36\u00b10.31; 1.06\u00b10.27; 0.97\u00b10.19\u2009Nm\/kg) was lower vs. non-involved leg (1.71\u00b10.36; 1.24\u00b10.33; 1.04\u00b10.15\u2009Nm\/kg; p&lt;0.01\u22120.02) for extension at 60 and 120\u00b0\/sec and flexion at 60\u00b0\/sec and vs. controls\u2019 \u2018matched\u2019 leg (1.77\u00b10.40\u2009Nm\/kg; p=0.01) for extension at 60\u00b0\/sec. Involved leg force (296\u00b145N) was lower vs. non-involved leg (375\u00b155N; p&lt;0.01) and vs. controls\u2019 \u2018matched\u2019 leg (372\u00b188N; p=0.02).
