The treatment of knee injuries often includes conservative treatment and surgery, as follows: First, conservative treatment: conservative treatment includes braking, rest, cold compresses for the knee joint, and a combination of ultrashort wave, microwave, and non-steroidal anti-inflammatory drugs, such as celecoxib capsules and loxoprofen sodium, etc. After the above treatment, mild knee injuries will gradually be relieved or even completely cured. Second, surgical treatment: Surgical treatment is also available. If the patient has a serious knee injury, such as fracture, joint dislocation, meniscal tear, cruciate ligament rupture or medial and lateral collateral ligament rupture, surgical treatment needs to be considered. Restoring the structural integrity of the lesion through minimally invasive surgery such as arthroscopy can ensure gradual restoration of joint function. After several methods of treatment, a satisfactory recovery of the knee injury can be achieved. Patients should also cooperate with rehabilitation training after treatment to enhance the stability of the joint.
