拼箱 眼泪
Overview
外侧副韧带（拼箱）是沿膝关节外侧延伸的一薄带结缔组织. 它连接股骨（大腿骨）和腓骨（小腿较细的长骨）。. Similar to the medial collateral ligament (at the inside of the knee), the 拼箱 works to stabilize the knee as it moves. 拼箱撕裂通常是由于对膝盖内侧的直接打击拉伸了外韧带，直到它撕裂. 撕裂可能发生在韧带中部或两端的任何地方.
人们经常在进行激烈碰撞的运动时撕裂拼箱, such as football or hockey. 拼箱和后外侧角（膝盖的背部和外侧部分）也可能在车祸中受伤, fall or another event that impacts the area. 重要的是要知道，拼箱撕裂通常与另一种膝盖损伤同时发生.

迹象 & 症状
The most common 症状 of an 拼箱 tear are pain, 刚度, swelling and tenderness along the outer side of the knee. Your knee may also feel loose, as though it will give way under stress. More severe tears can cause numbness or weakness in the foot; this occurs if the peroneal nerve (located near the 拼箱) is stretched at the time of injury or squeezed by subsequent swelling of the surrounding tissues.
诊断
The first step is a physical exam. Your doctor will check the outside of the knee for pain or tenderness, then apply pressure to the area while your leg is both bent and straight, which can indicate the severity of your injury.
有时，立即出现的疼痛和肿胀使人很难判断其严重程度. 在这种情况下, 你可能会被要求戴上一个轻型支架，并用冰敷和抬高膝盖，直到肿胀消退.
Your doctor may also order the following tests:
- x射线. These can reveal a fracture of the fibula or other bones, such as the femur and tibia (larger long bone of the calf).
- Magnetic resonance imaging (MRI). 该测试评估拼箱损伤的严重程度，准确率超过90%. 它通常用于确认韧带损伤的诊断，并检查软骨或其他膝关节韧带的损伤.
治疗
Treatment depends on the extent of injury. 严重的拼箱撕裂, which often happen along with other knee damage, 可能需要手术, followed by physical therapy. Less severe injuries usually respond to physical therapy alone. We offer the full range of physical therapies, including exercise regimens, 功能性活动和神经肌肉再教育（训练该区域恢复正常活动的技术）. 我们的专家指导每位患者通过个性化的方案，旨在促进愈合, recover function and improve physical performance.
Although severe injuries often require surgery, lesser damage usually responds well to nonsurgical treatment. Recovery time depends on the injury's severity.
Rehabilitation for an 拼箱 tear consists of:
- 休息一段时间
- 支撑
- 物理治疗
Once pain and swelling have subsided, 你应该能够开始锻炼来恢复力量和正常的活动范围.
If your torn 拼箱 doesn't heal sufficiently, you may experience instability in the joint, making it susceptible to reinjury. 手术治疗撕裂的拼箱通常需要全身麻醉，需要一到两个小时, 不过，如果其他膝盖损伤——比如前十字韧带撕裂——也需要手术治疗，则可能需要更长的时间. 外科十大赌博平台排行榜在膝盖外侧开一个切口，以便接近撕裂的韧带. 在某些情况下，用缝合线、螺钉或其他装置将韧带重新连接到骨头上. 在其他情况下, 韧带用患者另一侧膝盖或尸体膝盖的肌腱重建.
手术后，患者与物理治疗师密切合作，以恢复运动和力量. One to two weeks after surgery, you'll see the doctor again for a physical exam, removal of sutures and x射线. 手术后的六周内，你通常会使用拐杖和膝盖支架. 康复计划根据具体的损伤和手术程序而有所不同, 虽然完全恢复运动通常是在手术后9到12个月.
