VARIABLES PREDICTING AGILITY IN AMATEUR FOOTBALL PLAYERS AFTER MEDIUM-
TERM CROSS LIGAMENT RECONSTRUCTION: A MULTIPLE LINEAR REGRESSION
ANALYSIS.
Anterior cruciate ligament, agility, physical therapy assessment, muscle
performance
Introduction: Anterior cruciate ligament (ACL) injuries are among the most common in
sports, especially those involving agility. The surgery is performed using autograft and
aims to restore biomechanics and minimize knee instability.
Objective: The present study aims to evaluate the predictive variables of agility in soccer
players who underwent primary reconstruction surgery of the anterior cruciate ligament
using grafts from the contralateral and ipsilateral patella.
Methods: Cross-sectional study with male patients, soccer players, operated by the same
team and who are between 2 and 3 years after surgery. Individuals will perform a
functional assessment following the tests of: Agility (t-test); objective joint stability (KT-
1000TM); Leg Hop Test; Y Balance Test and muscle performance (Isokinetic).
Partial results: partial data from 44 (19 contralateral and 25 ipsilateral) subjects were
statistically analyzed by multiple linear regression. Among the variables tested, only joint
stability showed a significant result for (P=0.006) to predict agility.
