Quadriceps and hamstring torque were recorded using an isokinetic dynamometer. The anterior tibial translation was measured using the Kneelax 3 Arthrometer. The eccentric and concentric motor coordination was tested by multi\u2010joint lower\u2010limb tracking\u2010trajectory test. All measurements were taken 12\u00a0months after surgery.

However, side\u2010to\u2010side differences in flexor peak torque were significantly higher at 60\u00b0\/s for the STGR group than the ST group (<jats:italic>P<\/jats:italic> = 0.002).

This finding could be important for functional activity or sports with high demands on hamstring muscle strength. It is recommended that gracilis muscle should be preserved as possible during ACL reconstruction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>Prospective
