Get prescriptions or refills through a video chat, if the doctor feels the prescriptions are medically appropriate. Making a medial meniscal root tear diagnosis is difficult because the typical history of locking, catching or giving way is less likely to be present. MR imaging is reliable in the detection of meniscal tears and identification of meniscal fragmentation and displacement [1, 2, 3, 4].Displaced meniscal fragments are often clinically significant lesions requiring surgical intervention and, therefore, are important to identify. The healing time in children is a little less as the healing process is faster in children than in adults. They act as shock absorbers and stabilize the knee. AJSM 2003; 31:216-220.
