The knee joint is a relatively stable joint in the human body, and it acts as a connecting link in mechanics. Together, the platform is lined with elastic medial and lateral meniscus, reinforced by strong ligaments around the joint, and tibial collateral ligament on the inner surface. On the outside there is the peroneal collateral ligament, and the anterior and posterior cruciate ligaments located between the femorotibial articular surfaces are rich in extensive synovial infiltration, such as suprapatellar bursa, subpatellar bursa, and infrapatellar fat pad.
1 tendon: attached from front to back on the medial tibial condyle The sartorius from the anterior superior iliac spine to the medial condyle of the tibia, the gracilis from the upper and lower limbs of the pubic bone, the semitendinosus and semimembranosus from the ischial tubercle, and the lateral condyle of the tibia is attached to the hip that migrates down The tensor fascia lata, and the biceps femoris from the ischial tuberosity to the peroneal head, the powerful quadriceps in front, and the patellar ligament that is wrapped by the patellar quadriceps aponeurosis , attached to the back of the knee joint of the tibial tuberosity, above the medial and lateral condyles of the femur, respectively attached to the medial and lateral heads of the gastrocnemius originating from the calcaneal tubercle, and semimembranosus, tendon The membrane continues to the popliteal muscle formed at the middle and upper 1/3 of the tibia. It should be emphasized that the popliteus is the initiator muscle of the knee joint, also known as the golden key of the knee joint. Such a structure forms a situation where our left hand grasps the wrist of the right hand, and the right hand grasps the wrist of the left hand, like two tigers competing for a mountain.
2 Knee joint movement mode: The knee joint must have a relatively stable sliding force while rolling, so as to ensure the articular surface or joint head While exercising, it will not slip out of the joint surface. For example, when we stand on our feet and do squats, the medial and lateral condyles at the lower end of the femur roll backward and upward on the tibial platform, and at the same time make a forward movement. slide. In this way, the normal movement pattern of the joint must rely on the mutual coordination and mutual antagonism of the muscle groups around the joint to ensure the flexible and stable movement of the joint. Knee joint disease also affects the hip and ankle joints through tendon and mechanics.
3 What is a shock wave
A shock wave is a Physical wave is a discontinuous wave with impact force. This wave is characterized by strong explosive force and strong penetrating power, and can spread evenly in the same medium. It has been widely used in the treatment of soft tissue injuries. When we have been engaged in various chronic cumulative injury activities for a long time, walking, standing, and sitting for a long time, it will lead to muscle static muscle tension, chronic exudation, bleeding, and gradually form scars. The formation of subcutaneous induration, long-term pain. In this case, shock wave therapy is used. The shock wave will be blocked in the adherent tissue of these lesions, and thus collide in different directions, resulting in strong energy release, passively peeling off the adherent soft tissue, and loosening the damaged tissue from outside the body. Soft tissue, release the entrapped cutaneous nerve, treat lesions, and eliminate pain symptoms.
4 How shock waves treat knee pain
1) The patient lies prone on the treatment bed, with a pillow in front of the ankle, the shock wave impacts from the waist to the foot 100 times, and impacts Dachangshu and Huanju at the same time Acupoints, Chengfu, Weizhong, and Chengshan can achieve sedative and analgesic effects.
2) Gluteus maximus relaxation: the patient’s thigh is stretched back, placed on the doctor’s thigh and slightly abducted to make the buttocks bigger Relax the upper muscles as much as possible. Impact the lateral portion of the posterior superior iliac spine about three centimeters wide and 10 centimeters long. Relaxation of the upper bundle of the gluteus maximus can relieve the tension of the tensor fascia lata and reduce the tension on the outside of the knee joint.
3) Hamstring muscle group: The patient should lie down. When the knee joint is flexed, the doctor touches the groove formed by the semitendinosus, semimembranosus and biceps femoris with his hands, and impacts the tendons and cord trigger points in the groove, thereby reducing the pressure in the fascial compartment and promoting blood circulation. Backflow of circulating lymph fluid. At the same time, the patient actively cooperates with the flexion and extension of the knee joint.
4) Calf triceps release method: The patient is placed in prone position. An ankle bolster hits the calf and triceps. Then ask the patient to protrude the ankle about ten centimeters out of the bed. The doctor presses the upper end of the tibia with his right hand and the heel of the foot with his left hand. Press down on the heel for 40 seconds to one minute, then instruct the patient to bend hard, do five-second resistance exercises, and repeat the stretching exercise five times.
