The aim of this study was to ascertain whether there was a correlation between commonly used scoring scales used for follow-up study of management of knee problems and whether age, gender, and time interval between injury and management and type of management affect the assessment of outcome in the management of ACL insufficiency. One hundred and twelve patients who had received ACL reconstruction were identified from hospital records. Each of them received a package containing three questionnaires, namely the Lysholm knee score, Mothadi-QoL, and the Modified Cincinnati Rating Scale. The overall response rate was 55%. There was a relatively strong relationship between all three scores, with a very strong correlation between Cincinnati and Mohtadi questionnaires. The Lysholm score showed significant correlation between the method of treatment and outcome. Our study shows a good relationship between the three scoring systems, and helps to understand what questions should be asked to the patient with an ACL injury to elicit a true representation of their knee function
