A subcutaneous hematoma from a knee fall does not necessarily require surgery.
The treatment of subcutaneous hematoma depends on the specific condition of the knee, commonly used conservative treatment and surgical treatment.
If the hematoma is outside the joint and the amount is not large, conservative treatment can be carried out. Cold compresses can be applied within 72 hours, and hot compresses can be applied after 72 hours, and the hematoma may recover gradually, and if it fails to recover, puncture and aspiration of fluids can be carried out with compression bandage.
If the hematoma is large or recurs after puncture and aspiration, it may be caused by inflammation of the bursa and requires surgery.
If the hematoma is caused by a fracture of the knee bone or cartilage, or a meniscus injury, surgery is usually required.
Subcutaneous hematoma of knee injury should go to the hospital in time, and the doctor will determine the specific condition according to the symptoms, signs and auxiliary examination to determine whether surgical treatment is needed.
