Greater strength, endurance found in quadriceps after PCL tear vs ACL tear

Compared with ACL tears, the quadriceps muscle of the injured limb had greater strength and endurance after PCL tears, according to study results.

Researchers compared quadriceps and hamstring muscle strength and endurance between 20 prospectively enrolled patients with isolated PCL tears and a retrospective, matched control group of 20 patients with isolated ACL tears. Using an isokinetic testing device, the researchers evaluated the maximal torque and total work of the quadriceps and hamstring.
