Anterior Cruciate Ligament Injuries
Conditions
Brief summary
Anterior cruciate ligament reconstruction stabilizes the knee joint biomechanically and returns the patients back to the sportive activities. Numerous techniques exist to perform an anterior cruciate ligament reconstruction surgery. Remnant- preserving reconstruction technique is performed to increase surgery success rates and to accelerate the post-surgical return to sport process. In general, there is no consensus regarding the clinical outcomes of remnant-preserving anterior ligament reconstruction over standart procedure. The purpose of this study is to compare the patients who had remnant-preserving anterior cruciate ligament reconstruction with healthy controls in terms of muscle strength and proprioception.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Isokinetic muscle strength | 1 day | Isokinetic muscle strength values of the Quadriceps Femoris and Hamstring muscles in the knee joint will be measured using the Biodex® System Pro 4 (Biodex Cor. Shirley NY, USA) device. Subjects will perform a warm-up exercise for the knee joint at 75 pedal cycles per minute for three minutes on a bicycle ergometer prior to testing. After the warm-up exercises, the subjects will be allowed to rest for 10 minutes. Subjects will be seated on the isokinetic device chair with their backs perpendicular to 90º. Concentric isokinetic muscle strength measurements of the affected side and unaffected side quadriceps femoris and hamstring muscles of the subjects will be performed with 5 repetitions at 180º /sec, 240º /sec, 300º /sec after the torso, pelvic and thigh belts are attached. Between tests, subjects will be allowed to rest for one minute each. The peak torque values of the cases will be recorded in Nm. |
| Proprioception | 1 day | Biodex® System Pro 4 (Biodex Cor. Shirley NY, USA) device will be used to evaluate the proprioception sensation of the knee joint. The subjects will be asked to sit on the isokinetic dynamometer device with the knee joint in 90º flexion. The sense of proprioception of the operated and non-operated knees will be measured at three different angles of 20º, 50º and 70º. During the test, the target angle will be displayed by the device and the limb will be held in this position for 10 seconds. Then, returning to the starting point, the subject will be asked to actively find the target angle with eyes closed. The scores will be averaged by repeating the measurements three times for each reference angle. A rest period of 3 minutes will be allowed between different reference angles. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Kinesiophobia | 1 day | The level of fear of movement of the participants will be evaluated with the Tampa Kinesiophobia Scale which is a 17-item scale developed to measure fear of movement/re-injury. The scale includes parameters of injury/re-injury and fear and avoidance in work-related activities. The scale evaluates fear of movement with a 4-point Likert-type scoring system (1= Strongly disagree, 4= Totally agree). While the total score is determined between 17-68, a higher score means that the fear of movement is greater. |
