Using an instrumented pressure mat, patients completed 3 sets of 3 repetitions of bodyweight squats.

A limb-by-time interaction for quadriceps peak torque (N\u00b7m) was observed where the ACLR limb increased peak torque across visits (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.01); however, strength deficits persisted at visit 2 (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.01) when compared with the nonoperative limb.
