The discoid meniscus lack of normal function is different in anatomicalfeature and histological structure and with natural meniscus. It’s one of thereasons that could cause knee instability, easily leading to the dysfunctionof the corresponding knee. Discoid meniscus injury often occurs in youngadults, while the type of injury has its own characteristics. Once damagedthe discoid meniscus will show a range of symptoms. The knee would turnto limited mobility, instability, accelerated degeneration and other moreserious consequences if it was not treated properly or adequately. So theearlier diagnosis and appropriate treatment are made, the better prognosiswill appear. With the help of current surgical techniques, especially thedevelopment of arthroscopic treatment, it’s possible to carry out themeniscal suture repair with partial meniscectomy at the same time. Andnew surgery such as meniscus transplantation is also carried out after totalmeniscectomy. The anatomy, etiology, clinical manifestations, diagnosticmodalities and criteria, and practical management considerations arereviewed. |
