[Research progress on the application of lower limb alignment in discoid meniscus injury].

Discoid meniscus injury is a kind of common sports injury. Its treatment methods include arthroscopic discoid meniscus plasty, discoid meniscus subtotal resection, discoid meniscus total resection and so on. Although the short-term clinical effect is good, the long-term clinical effect is not ideal. At present, different scholars have different views on the choice of surgical methods for discoid meniscus injury. In recent years, many scholars have shown that the choice of operation and the change of lower limb force line are related to the therapeutic effect of discoid meniscus injury. This paper mainly summarizes the current situation of the treatment of discoid meniscus injury and the changes of the force line of the lower limbs after operation, and expounds therole of the evaluation of the force line of the lower limbs in the treatment of discoid meniscus, so as to provide the basis for the clinical individualized treatment of discoid meniscus injury.
