The purpose of this CRT study is to compare clinical and functional outcomes of three graft types ( Quadriceps tendon with bone versus Hamstring tendon versus Quadriceps tendon without bone) for reconstration of anterior cruciate ligament among football players.
In the previous studies patellar tendon and hamstring tendon were the most investigated graft types. While quadriceps tendon has been investigated a fewer times. And to our knowledge there is no control study that compare quadriceps tendon-patellar bone autograft with Quadriceps Autograft and Hamstring Autograft as control randomized study. All of the patients will be examined before of the surgery and 3, 6, 12, 24 months after the surgery to compare the outcome of differnt graft types. While a secand aim of this study is to examen the effect of rehabilitation protocol on the short and long term within all of the clinical and the functional outcomes. The rehabilitation protocol will contain one phase before the surgery and four phases after the surgery.The goal of the first phase will be pain and inflammation control, increase ROM and muscle strength will be during the second and the third phases.In the last phase all of the players have to achieve maximum muscle strength and neuromuscular control.

change of Isokinetic strenght test
the assessment will be made with GENU 3 dynamometer (GENU 3, Easytech, Firenze, Italy), using isokinetic parameters at angular velocities of 60°/sec (3 repetitions), 180°/sec (5 repetitions) and 300°/sec (15 repetitions) with 30 seconds of rest among these. To determine the height of the chair, the lateral femoral condyle was aligned with the rotational axis of the dynamometer. The peak torque, average torque and flexor-extensor torque rate value. Patients will be warm up in a cycle ergometer previously (5 min) and them performing mobilization exercises and stretching in lower limbs (5 min).
Time frame: Patients will be examined before , after 3 , 6 12 and 24 month of the surgery
Visual Analogical Scale
the participants will be completed a visual analogue scale (0-10 points) to assess the presence of knee pain.
Time frame: Patients will be examined before , after 3 , 6 12 and 24 month of the surgery
Pressure Pain Thresholds
We will use an electronic algometer (Somedic AB, Farsta, Sweden) over 6 points: epicondyle (1), at the midpoint between the greater trochanter and the lateral condyle of the femur on the external (2), at three centimeters above the patella in the vastus medialis (3), at the midpoint between the lower pole of the patella and the anterior tuberosity of the tibia (4), at 3 cm above the patella in midline of the thigh (5) and at the inclusion of the goose leg. The mean of 3 trials will be used for the main analysis.
Time frame: Patients will be examined before , after 3 , 6 12 and 24 month of the surgery
MUSCLE ARQUITECTURE
an ultrasound device (MyLab™ 25, Esaote Medical Systems,Genova, Italy) and a 12 MHz linear probe will be used in this study. The depth and width of quad tendon and articular cartilage of femoral trochlea will be captured.
Time frame: Patients will be examined before , after 3 , 6 12 and 24 month of the surgery

All patients will receive six months rehabilitation program which aim to recover the strength and function
ANTEROPOSTERIOR LAXITY
it will be measured using the KT-2000 TM arthrometer (MEDmetric, Sn Diego, CA, USA)
Time frame: Patients will be examined before , after 3 , 6 12 and 24 month of the surgery
Tegner questionnaire
It is a subjective satisfaction index of on a scale of 0 to 100
Time frame: Patients will be examined before , after 3 , 6 12 and 24 month of the surgery
Single-legged hop test
The patient is placed standing on one leg and must jump as far as possible landing on the same leg.
Time frame: Patients will be examined before , after 3 , 6 12 and 24 month of the surgery
