The Lysholm scale is a well validated functional score designed for knee ligament injuries but has also been validated for other knee injuries. Different scores are more useful at different stages post ligament reconstruction. Functional rating scales may have to be modified for articular cartilage repair.
Rating systems for ligament evaluation should look at functional score, activity grading and static stability assessment and functional test before during and after ligament reconstruction.
