Joint capsule injuries are generally caused by external blows, crushing, collision or weight bearing, twisting and other activities, resulting in local swelling, pain, skin ecchymosis, limb movement restrictions and other symptoms. The most common are finger, knee, ankle injuries, we should give ice and local braking at the time of injury. If there is obvious pain, you can analgesic drugs symptomatic treatment, serious to give a cast or bandage for external fixation. The duration of immobilization is usually about 2-3 weeks. After the acute period, local physical therapy and rehabilitation of joint function can be carried out. If there is a joint dislocation, ligament rupture or open injury, surgical repair is required to repair the ligament or joint capsule. Joint capsule injury in our life many people generally after trauma without bleeding, will use some blood circulation drugs, for local rubbing, this treatment is wrong. Because in the early stage of joint injury, the capillaries rupture, we need the ruptured capillaries to contract to stop the bleeding. In the acute stage, we need to apply ice, but many people do the opposite, using hot compresses or blood-boosting medications like Yunnan Baiyao for local rubbing, which can cause the stumps of the broken and contracted blood vessels to re-expand and bleed again, resulting in more swelling and pain at the injured site. So when it comes to this kind of joint capsule injury, we must remember that in the early stage of the injury, especially within eight hours, we should take ice packs as much as possible, and then after 24 hours, we should use blood-stasis-activating drugs for local treatment.
