一个女人疼痛的膝盖

The knee is formed by the femur (thigh bone), the tibia (shin bone) and the patella (the knee cap). It is essentially a hinge joint that is held in place by the medial collateral (MCL), 侧抵押(拼箱), 前十字韧带(ACL)和后十字韧带(PCL).

Most of us have heard that women athletes are more prone to suffering from a traumatic knee injury. But what most people don't know is that you don't have to be a weekend warrior to end up with a serious knee problem. Each year, 大约有1000万女性因为膝盖疼痛去看十大赌博平台排行榜, 通常是由与运动无关的活动引起的, 比如起重箱, 在园艺时爬楼梯或蹲得太久.

为什么女性膝盖受伤越来越多? 研究人员猜测，最可能的原因之一是女性的体型. Women tend to have wider hips and are slightly knock-kneed (their thighbones tend to curve inward from the hip to the knee) and this alignment can create added stress on the joints. 另一个原因可能与女性的肌肉有关. 更常见的是，女性使用腿部肌肉的方式与男性不同.

Here are some common knee problems women encounter and tips from UCSF orthopedic surgeons and knee specialists on how to prevent them:

问题:髌骨或膝盖骨疼痛(膝盖骨前部疼痛)

When working properly, your patella should glide straight up and down as you extend your leg. But sometimes the kneecap slides slightly off track and rubs against the bone and cartilage nearby. 这会导致膝盖前面和膝盖骨后面的疼痛和肿胀. 你还能听到噼啪声.

Solution

防止疼痛, it's important to build up muscle endurance and strengthen the quadriceps muscles in the front of your leg. You'll also need to stretch the muscles and tendons that may be tight such as the hamstrings (in the back of the leg) and the iliotibial band (on the outer side of the leg). 避免可能加重膝盖骨的活动也是明智的, 比如爬楼梯, 在山上跑上跑下，过度下蹲.

问题:内侧副韧带撕裂

The MCL is usually injured when the outside of the partially flexed knee is struck with the foot fixed to the ground. Injury to the MCL can also occur with excessive lateral rotation (outside twisting) of the knee. 这种力量使膝盖内侧变宽, 创建拉伸, 韧带部分撕裂或完全撕裂. An injury to the MCL may be isolated or a component of a more complex knee injury. The injuries that frequently occur in combination with MCL tears are ACL and meniscus (cartilage) tears. The most common symptom following an injury to the MCL is pain directly over the ligament on the inner portion of the knee. 如果只是MCL受伤, 大多数病人在急性受伤后仍能继续行走, however they often have difficulty with activities involving pivoting and twisting. Pain and stiffness in the joint are localized to the inner part of the knee and the area may become swollen. 更严重的MCL撕裂可能会给患者一种不稳定的感觉.
