If the pain is more pronounced after a traumatic knee injury, there may be a bone fracture or fracture, or there may be a meniscal or cruciate ligament injury in the knee. If a bone fracture or fracture is considered, an x-ray of the knee joint should be completed and further CT and 3D reconstruction should be done if necessary. If a knee meniscus or cruciate ligament injury is considered, an MRI of the knee joint needs to be completed to determine the condition. If there is no fracture and no obvious meniscus or cruciate ligament injury after examination, consider local soft tissue injury, pay attention to rest, local swelling and pain aerosols can be sprayed, oral Luofen-zoin extended-release tablets for pain relief, 1-2 weeks can generally recover.
