This can be explained: due to the different arrangement of collagen fiber bundles in different positions of the meniscus, it leads to different anatomical lesions: lesions at the meniscal margin. Close to the joint capsule is usually a longitudinal tear, the injury in the free part is usually a transverse tear or a flap tear. In addition, the type of meniscal injury depends on age as shown by the thickness and quality of the cartilage layer of the tibial and femoral facets. Young people have thick, elastic, and well-absorbed articular cartilage, so they often see longitudinal tears. Adults over 30 years old cartilage quality begins to decline, unable to absorb rotational forces, resulting in a horizontal tear or a diagonal tear. In the elderly, there is a lot of degeneration of the cartilage, the cartilage layer is lost, the joint space of the knee joint narrows, the rolling motion of the condyle on the tibial plateau is subject to much friction, so there is often a ragged tear.<sup>(5,4,6)<\/sup>. In our study group, the group over 30 years old accounted for more than other authors, which could explain the second highest rate of our cross tear group after longitudinal tear group.<\/p>\n<p><strong>Distribution of tear area<\/strong><\/p>\n<p><strong><em>Table 3: <\/em><\/strong><em>Distribution of tear area<\/em><\/p>\n<table>\n<tbody>\n<tr>\n<td>\n<p><strong>Torn area<\/strong><\/p>\n<\/td>\n<td>\n<p><strong>SL<\/strong><\/p>\n<\/td>\n<td>\n<p><strong>TL%<\/strong><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>Red-red zone<\/p>\n<\/td>\n<td>\n<p>24<\/p>\n<\/td>\n<td>\n<p>22,6<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>Red-white area<\/p>\n<\/td>\n<td>\n<p>38<\/p>\n<\/td>\n<td>\n<p>35,9<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>White\u2013white area<\/p>\n<\/td>\n<td>\n<p>44<\/p>\n<\/td>\n<td>\n<p>41,5<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p>Total<\/p>\n<\/td>\n<td>\n<p>106<\/p>\n<\/td>\n<td>\n<p>100<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Ch\u00fang t\u00f4i g\u1eb7p c\u1ea3 3 nh\u00f3m r\u00e1ch \u1edf v\u00f9ng \u0111\u1ecf- \u0111\u1ecf: 24\/106 tr\u01b0\u1eddng h\u1ee3p (chi\u1ebfm t\u1ef7 l\u1ec7 22,6%), v\u00f9ng \u0111\u1ecf-tr\u1eafng: 38\/106 tr\u01b0\u1eddng h\u1ee3p (chi\u1ebfm t\u1ef7 l\u1ec7 35,9%), v\u00f9ng tr\u1eafng-tr\u1eafng: 44\/106 tr\u01b0\u1eddng h\u1ee3p (chi\u1ebfm t\u1ef7 l\u1ec7 41,5%), s\u1ef1 kh\u00e1c bi\u1ec7t n\u00e0y kh\u00f4ng c\u00f3 \u00fd ngh\u0129a th\u1ed1ng k\u00ea.
