Effect of Rehabilitation Programs Based on Eccentric Exercise of Knee Extensor Muscles in Isotonic and Isokinetic Conditions After Partial Menisectomy

A randomized clinical trial involving 32 individuals submitted to partial menisectomy 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 15 days after partial menisectomy. The programs will last six weeks, with training frequency of two sessions per week, separated by a minimum interval of 72 hours.

Treatment and study plan

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.

15 days after partial menisectomy, 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.

Isotonic 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.

15 days after partial menisectomy, subjects randomly allocated to this arm will be submitted to a muscle rehabilitation program based on isotonic eccentric exercise lasting six weeks, with training frequency of two sessions per week, separated by a minimum interval of 72 hours.

Primary outcomes

  1. The femoral quadriceps muscle mass through nuclear magnetic resonance imaging

    Time frame: Change from baseline and six weeks after intervention protocol

Secondary outcomes

  1. Performance of knee extensors through computerized dynamometry

    Time frame: Change from baseline and six weeks after intervention protocol

  2. Functionality of the individuals through Lysholm score

    Time frame: Change from baseline and six weeks after intervention protocol

  3. Functionality of the individuals through single and triple hop test

    Time frame: Change from baseline and six weeks after intervention protocol
