- Is the Turkish version of the Tegner Activity Score a reliable scale?
- What is the minimal clinically important difference value of the Turkish version of the Tegner Activity Score?
- What is the substantial clinical benefit value of the Turkish version of the Tegner Activity Score?
- Conditions
- Knee Injuries
- Being tested
- Anterior cruciate ligament reconstruction

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Anterior cruciate ligament reconstructionProcedure or surgery
Patients with anterior cruciate ligament rupture will undergo anterior cruciate ligament reconstruction surgery.
| Study group | Role | What they receive |
|---|---|---|
| Anterior Cruciate Ligament Injury Patients | Patients who will undergo anterior cruciate ligament reconstruction because of anterior cruciate ligament rupture Receives: Procedure: Anterior cruciate ligament reconstruction |
What is being measured
The primary outcome is the main question the study is designed to answer.
Functional level
Tegner Activity Score (total score between 0-10) (higher values indicate higher functional level)
Measured: before the surgery, after 1 week from the surgery and after 3 months from the surgery
Secondary outcomes (2)
Functional level
Lysholm Knee Score (total score between 0-100) (higher values indicate higher functional level)
Measured: before the surgery
Functional level
International Knee Documentation Committee-Subjective Knee Evaluation Form (total score between 0-100) (higher values indicate higher functional level)
Measured: before the surgery
