Quadriceps Muscle Activation as Assessed by Surface Electromyography (sEMG) |
Quadriceps muscle activation was examined using surface electromyography (sEMG) of the vastus medialis oblique muscle. Peak sEMG activity was recorded in microvolts (uV) on the surgical and contralateral limbs while performing five maximal effort isometric contractions in full knee extension--the reported values are equal to the quadriceps sEMG in uV of the contralateral limb minus the quadriceps sEMG in uV of the surgical limb. |

Number of Successful Repetitions With Straight Leg Raise Test |
The straight leg raise assessment was performed in a standardized long-sitting position with well-knee flexed to 90 degrees. Patients were asked to complete 30 repetitions of straight leg raises with a small bolster supporting the heel using the following criteria; (1) perform with no visible quad lag (2) reach the height of the opposite tibial tubercle and (3) maintain a controlled rate of 30 hertz for the ascending and descending phases. The examination was only performed on the surgical limb and the absolute number of successful repetitions is reported. |
