• anterior eructate ligament reconstruction
• predictor of jogging
• isokinetic muscle strength of leg extensors

The purpose of this study was to determine if there were any reliable predictors for achieving jogging requirements after anterior cruciate ligament (ACL) reconstruction We analyzed associations among variables collected from 128 subjects at 12 weeks postoperatively, including jogging parameters (i e pain, apprehension, speed, and distance), the isokinetic muscle strength of the leg extensors, the knee stability, and patient's profiles (i e age, sex, activity level, body mass index (BMI). memscectomy, and cartilage injury)
Jogging parameters were significantly correlated with the isokinetic muscle strength of leg extensors but not with the knee stability With the jogging ability of achieving a distance of 2000m at a velicity of 9km/h being an objective variable, a logistic regression analysis revealed that the isokinetic muscle strength of leg extensors and BMI were considered relevant Using a receiver operating characteristic (ROC) curve analysis and a contingency table. the cut-off values of the isokinetic muscle strength of leg extensors to the uninvolved side and body weight were 85% and 1.9Nm/kg, respectively, whose sensitivity and specificity were 0.90 and 0.82. respectively Therefore, we concluded that the isokinetic muscle strength of leg extensors is a reliable predictor for projecting the timing to start jogging after ACL reconstruction (Jpn J Phys Fitness Sports Med 2010, 59 : 281 similar to 290)
