**3. Clinical presentation**

There were 2 presentations of patients with meniscal root tear.


Meniscus root tear's diagnoses is challenging. Patient might not have a problem of locking or catching knee. Medial knee pain and joint line tenderness are the most common symptom and sign especially at the posteromedial of the knee joint. Deep flexion of the knee might provoke the pain. Meniscus specific test such as Mcmurray's test was positive in 57%. Joint effusion presented in 14% [28]. Compared to other meniscus injuries, medial meniscus root tears are common in Asian populations, in particular, females and higher Body Mass Index (BMI > 30 kg/m2 – 4.9 fold increase) patients. If patient had a varus mechanical axis, the risk of medial meniscus posterior root tear increased by 3.3-fold [29]. Generally, we recommend further investigation such as, an MRI in patients with progressive medial joint knee pain with no or mild osteoarthritis to rule out medial meniscus posterior root tear.
