Study summary

The goal of this observational study is to learn about patients who will undergo anterior cruciate ligament reconstruction. The main questions it aims to answer are:

  • Is the Turkish version of the Tegner Activity Score a valid scale?
  • 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?

What researchers measure

Primary outcomes

  1. Functional level

    Tegner Activity Score (total score between 0-10) (higher values indicate higher functional level)

    Time frame: before the surgery, after 1 week from the surgery and after 3 months from the surgery

Secondary outcomes

  1. Functional level

    Lysholm Knee Score (total score between 0-100) (higher values indicate higher functional level)

    Time frame: before the surgery

  2. Functional level
