Brief Summary

A randomized clinical trial involving 30 individuals submitted to ACL reconstruction will be conducted. Participants will be randomized into: Group I, submitted to a muscular rehabilitation program based on eccentric isokinetic exercise; and Group II, submitted to a muscular rehabilitation program based on eccentric isotonic exercise. Concomitantly with the muscular rehabilitation protocols, individuals will undergo the same physiotherapeutic protocol with analgesia, edema reduction, range of motion, proprioception and functionality goals. Muscle rehabilitation programs based on eccentric isotonic and isokinetic exercise will begin 45 days after ACL reconstruction. The programs will last six weeks, with training frequency of two sessions per week, separated by a minimum interval of 72 hours.

Conditions

Anterior Cruciate Ligament Injury

Outcome Measures

Primary Outcomes (1)

• The femoral quadriceps muscle mass through nuclear magnetic resonance imaging

  Change from baseline and six weeks after intervention protocol

Secondary Outcomes (3)

• Performance of knee extensors through computerized dynamometry

  Change from baseline and six weeks after intervention protocol

• Functionality of the individuals through Lysholm score

  Change from baseline and six weeks after intervention protocol

• Functionality of the individuals through single and triple hop test

  Change from baseline and six weeks after intervention protocol

Study Arms (2)

Group 1.

EXPERIMENTAL

The participants randomly allocated to this arm will undergo a muscular rehabilitation program based on the isokinetic eccentric exercise for the extensor muscles of the operated knee. The contralateral non-operated lower limb will be used as control, so it will not undergo any muscular rehabilitation program.

Other: Isokinetic eccentric exercises

Group 2.

ACTIVE COMPARATOR

The participants randomly allocated to this arm will undergo a muscular rehabilitation program based on the isotonic eccentric exercise for the extensor muscles of the operated knee. The contralateral non-operated lower limb will be used as control, so it will not undergo any muscular rehabilitation program.

Other: Isotonic eccentric exercises

Interventions

Isokinetic eccentric exercises OTHER

The individuals of both groups will be submitted to the same physiotherapeutic protocol with objectives of analgesia, reduction of edema, recovery of range of motion, proprioception and functionality. 45 days after ACL reconstruction, subjects randomly allocated to this arm will be submitted to a muscle rehabilitation program based on isokinetic eccentric exercise lasting six weeks, with training frequency of two sessions per week, separated by a minimum interval of 72 hours.

Group 1.

Isotonic eccentric exercises OTHER
