ACL quality of life

The ACL Quality of Life (ACL-QOL) is a patient-reported outcome measure designed to assess the impact of anterior cruciate ligament (ACL) injury on the patient's quality of life. It was developed by Ronald C. Kessler, M.D., M.P.H., and his colleagues in 1998 and has since been widely used in clinical practice and research. The ACL-QOL questionnaire consists of 32 items across five domains, including symptoms, sports activities, work activities, social activities, and emotions. Each item is rated on a 5-point Likert scale, with higher scores indicating better quality of life. The total score ranges from 0 to 160, with higher scores indicating better quality of life.

The ACL-QOL is used to evaluate patients with ACL injuries who have undergone surgical or non-surgical treatment. It is often used as part of a comprehensive assessment that includes a physical examination, imaging studies, and other outcome measures.

The ACL Quality of Life (ACL-QOL) questionnaire is scored by adding up the responses to each item, with a possible total score ranging from 0 to 160. Higher scores indicate better quality of life and a lower impact of the ACL injury on the patient's daily activities and emotions.

There are no strict cutoffs for what is considered a "normal" score on the ACL-QOL, as the normal range can vary depending on factors such as age, sex, and activity level. However, in general, a score above 120 is considered to indicate good quality of life, while a score below 80 is considered to indicate poor quality of life.
