Advances in the treatment of medial meniscus posterior root tear

Abstract

With the continuous progress of diagnosis and technology on knee osteoarthrosis, the concept of stepwise treatment and keeping meniscus as much as possible has been deeply rooted in people's minds. As an important anatomical structure for maintaining the annular tension of the medial meniscus of the knee, more and more attention has been paid to the posterior root. After the root tear of the medial meniscus, the annular tension loss, leading to the meniscus bearing load function partial or complete loss, and secondary knee medial space narrow, cartilage degeneration and genu varus deformity. In the of root tear of the medial meniscus different scholars hold different views. The of the medial meniscus posterior root tear of the knee is mainly conservative and operative treatment, and the conservative mainly includes non-steroidal drugs, functional exercise, physical therapy, and so on. The surgical mainly included the medial meniscus partial resection of the medial meniscus under the arthroscope, the medial meniscus posterior root repair under the arthroscopy, and osteotomy with medial meniscus posterior root repair under the arthroscopy. Despite the short-term curative effect of conservative therapy and resection is satisfied, long-term follow-up has no obvious improvement with knee pain, function and activity levels, and causes secondary biomechanical change of knee. For patients of age 90°) genu varus >5°, osteotomy can effectively improve the clinical curative effect. However, whether to repair the medial meniscus posterior root together is still controversial.
