Establishing the Clinical Significance Values of the Lysholm Knee Score

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: * What is the minimal clinically important difference value of the Lysholm Knee Score? * What is the substantial clinical benefit value of the Lysholm Knee Score? * What are the risk factors that prevent patients who have undergone anterior cruciate ligament reconstruction from reaching the minimal clinically important difference value? * What are the risk factors that prevent patients who have undergone anterior cruciate ligament reconstruction from reaching the substantial clinical benefit value?
