Excerpt
The purpose of this study was to examine the relationship between an isokinetic knee-flexion-extension strength ratio and Lysholm score in subjects with anterior cruciate ligament (ACL) reconstruction who were professional athletes. Fifteen subjects, three females and twelve males (age mean=24.13 years-old) between 24-52 weeks postoperative ACL reconstruction. Concentric isokinetic knee-flexion-extension strength ratio was evaluated using a Cybex isokinetic system at a speed of 180 degree/sec. Subjects were given one minute rest followed by five maximal efforts extension. The identical protocol was also repeated on the contralateral limb. On the day of functional testing, subjects were given instructions and day reply Lysholm test form. Flexion-extension work ratio value means were 91.8±6.25 for the involved limb and 83.4±4.4.78 for the uninvolved limb. Mean score for Lysholm test were 89.2±3.45 for patients with ACL reconstruction. Pearson-product moment correlation coefficients values between Lysholm Score and flexion-extension ratio were.54 and.61 for the involved and uninvolved limb respectively. This suggests a moderate correlation and that isokinetic testing alone may be sufficient to clinically assess a patient's readiness to return a dynamic functional level.
