Meniscal Lesions in Return to Sport After Anterior Cruciate Ligament Reconstruction

Correlation between TSK, ACL-RSI Score and mCRSQ Score

Tampa Scale of Kinesiophobia is a 17 item questionnaire used to assess the subjective rating of kinesiophobia or fear of movement. A score of 17 is the lowest possible score, and indicates no kinesiophobia or negligible. A score of 68 is the highest possible score and indicates extreme fear of pain with movement. ACL Return to Sport after Injury measures the patient's understanding of his knee. It comprises 12 questions with a score of 1 to 10 for each. It is considered that for a normal population without knee condition, the score is between 80 and 90%. modified Cincinnati Rating System Questionnaire has been designed to give your therapist information as to how your knee pain has affected your ability to manage in everyday life. It consists of 12 questions, 8 of which are included in the summary score. The total score is calculated as the sum of all questions responses, with 100 representing the best/excellent knee function, and 0 representing the worst/poor knee function.

Correlation between clinical and psychological features

Clinical assessment consist of three tests carried on during medical check-up: i) active and passive Range Of Motion (ROM); ii) anterior drawer test; iii) knee's alignment. All these measurements will be transformed in categorical variables in order to perform chi square test.

Association between clinical features and level of stability

Clinical assessment consist of three tests carried on during medical check-up: i) active and passive Range Of Motion (ROM); ii) anterior drawer test; iii) knee's alignment. All these measurements will be transformed in categorical variables. During the stability test, the patient stands with one and two legs respectively on a free to move balance disc for 30 seconds. Subjects were instructed to stand in the centre with their arms at their sides. Level of stability is defined as an index ranking from 1 (low stability) to 5 (high stability). Eta square between categorical variables from clinical assessment and the measure outcomes of biomechanical assessment will be performed.

Association between clinical features and limb symmetry index

Clinical assessment consist of three tests carried on during medical check-up: i) active and passive Range Of Motion (ROM); ii) anterior drawer test; iii) knee's alignment. All these measurements will be transformed in categorical variables. During jump tests, the subject carried a belt around their hips, and the sensor was placed above the greater trochanter of the hip. Before jumping, the subject had to stand in an upright and still position. A sequence of four different jumps has been executed. The limb symmetry index (LSI) was calculated by dividing the measured value of the injured leg by the value of the non-affected side and multiplying by 100. Eta square between categorical variables from clinical assessment and the time required to perform the test will be calculated.

Association between clinical features and Coordination Time

Clinical assessment consist of three tests carried on during medical check-up: i) active and passive Range Of Motion (ROM); ii) anterior drawer test; iii) knee's alignment. All these measurements will be transformed in categorical variables. The subject performed one-footed jumps through the course of red (forward-backward-forward jumps) and blue (sideway jumps) hurdles, completing 16 jumps. This had to be performed as quickly as possible by jumping on one leg without a rest between the hurdles. Eta square between categorical variables from clinical assessment and the time required to perform the test will be calculated.
