Meniscus and lower limb alignment play an important role in load transfer of knee joint and has internal relationship between them. At present, different scholars have different views on the choice of surgical methods for patients with medial meniscus injury with knee varus. In recent years, many scholars have shown that choice of operation and abnormal lower limb alignment are related to repair and healing of medial meniscus injury and clinical effect. Therefore, evaluation of lower limb alignment should pay attention on diagnosis and treatment for patient with medial meniscus injury. This paper summarizes biomechanical function and internal relationship between meniscus and lower limb alignment, and expounds the interaction between medial meniscus posterior root injury, degenerative injury, acute tear and lower limb alignment, respectively. It shows that osteotomy plays an important role in repairing medial meniscus injury and the occurrence and development of knee osteoarthritis in patients with abnormal lower limb alignment and medial meniscus injury. It is expected to provide theoretical guidance for the clinical treatment of patients with medial meniscus injury with abnormal lower limb alignment.
