Abstract

The alteration of the strength of the quadriceps and hamstrings after six months of reconstruction of the anterior cruciate ligament (ACL) induces a decrease in performance and can cause injury. Hypothesis: The muscular strength of the operated side of anterior cruciate ligament after 6 months of surgery shows some muscular weakness in the quadriceps and hamstrings in comparison with the healthy side. Motor performance will be dependent on the total recovery of muscle strength of these young athletes. Purpose: This study evaluated the isokinetic muscle strength parameters after 6 months of anterior cruciate ligament rehabilitation in young athletes. Methods: We measured muscle strength of 50 patients, 6 months after surgery after ACL reconstruction. The parameters used to evaluate the strength of the quadriceps and hamstrings were the: peak torque, average power, total work, max repetition total work and the ratio agonist / antagonist (AGO/ANTAG). They were studied at various speeds: 120, 180.300 degrees / sec. Results: muscle strength in the operated side after 6 months of conservative treatment shows a deficit only at the level of the quadriceps muscle in comparison with the healthy side. Conclusion: hamstrings are recovered more quickly than the quadriceps.
