2. The study is aimed at helping to make a decision on whether an athlete can get back to sporting activities or not after anterior cruciate ligament reconstruction due to their physical performance. The case study can be applied in athletes to conduct a vail sport test which checks physical performance in terms of movement quality, muscle strength, endurance, and power after ligament reconstruction.

3. The case study fits into existing research literature due to assess the reliability of Vial Sport Test, which has been used in sports over time to establish the physical performance of the ACL-reconstructed patients. The application of the Vial Sport Test shows its reliability in this case as long as the score is done on repeated occasions, though the method cannot be used to measure the overall quality of movement.
4. The participants included thirty ACLR patients, with twelve being female and eighteen men. These participants were volunteers undergoing rehabilitation. These individuals were selected from the ages of eighteen to twenty-three years, and they must have taken about five months from the time of surgery.
5. The study was recorded using a video from the front and lateral views. The first video contained the single-leg squat which was recorded for three minutes, the second video taking ninety seconds recorded the lateral bounding and the third and fourth videos, each two minutes captured the forward and backward jogging.
6. i. Flexing of the knees at 30 degrees once the foot had contracted the ground
ii. Lateral bounding using a sports cord
iii. Forward and backward jogging utilizing the resistance of a sport cord
iv. Repeating the activities several times.
7. Data contained the number of times the patients could conduct physical activities such as jogging, squatting, and lateral bounding. Data was collected through videotaping the anterior and lateral views of the performance using therapists. The videos were recorded within thirty seconds interval for each participant. The test scores made up the data used in the study.
8. The computer program that was used in the calculation of the data was SPSS version 19.0. The question that the data was designed to answer was whether Vial Sport Test could be used as a reliable test for athletes who had undergone anterior cruciate ligament reconstruction.
9. Out of the possible 54 points, the average Vial Sport Test indicated a score of 45 as shown by the calculation of three graders. The single-leg squat recorded a score of 13; lateral bounding had 11.9, forward jogging with 10.1 and backward jogging with a score of 10.
10. the study conducted indicated that Vial Sport Test can be used as a dependable means in establishing physical performance of the ACL-reconstructed patients, as long as it is done on repeated occasions. Therefore, before sending ACL-reconstructed patients to the field again, it is necessary to measure and establish whether they are fit or not.
11. The caution the authors raised about the study is the lack of prior evidence on reliability of the Vial Sport Test. That creates doubt on whether it can be used on all occasions without misguiding athletes on their physical performance in the field.
12. The report does not provide enough history on Vial Sport Test, it is even indicated that there is no enough evidence showing that it's reliable, but the study concludes by showings its reliability. The information may mislead some athletes on their physical performance, and that may put them in danger if they practice without being fully recovered after ligament reconstruction.
