Once a sports injury occurs, if it does not receive timely and correct treatment and treatment, it is easy to cause irreversible damage to the function of the limb, which may affect our motor function, or cause disability. So how should the correct treatment when a sports injury occurs? How to properly deal with sports injuries after they occur? In the acute phase of the injury, the first step is to do the first step is to brake the injured part to prevent it from further stress stimulation injury expansion, generally using plaster or brace fixation. Many people immediately after the injury to apply ointment, rubbing medicinal wine, such as safflower oil, which is wrong. Joint sprains and strains should be iced first and then treated with topical medication only after 48 hours. After the injury should be kept long enough to rest, not too early to return to the sports field, to prevent old injuries are not healed and add new injuries. The most common misconception is not to take it seriously, hoping that you can recuperate and miss the best time for treatment. Sometimes there is no abnormality in the bone, so we think there is no problem, but we don’t know that MRI is needed to confirm the diagnosis of joint cartilage, ligament and tendon injuries. The following is a detailed description of the treatment of some common joint sports injuries in clinical work: 1, ankle sprain “broken foot” is very common in daily life, many people think it is a “minor injury” and hope to get well, thus delaying the treatment. Ankle sprains can cause damage to the ligaments of the ankle joint, especially the lateral collateral ligaments, which are commonly caused by jumping and stepping on foreign objects and breaking the foot. Repeated ankle sprains can also damage joint cartilage and lead to osteoarthritis. The initial acute sprain should be treated with pressure bandages, ice, rest and elevation of the affected limb; after the pain is relieved, active ankle movement, gradual walking and muscle training should be performed. For patients with repeatedly broken feet and obvious instability of the ankle joint, timely surgery should be performed to repair the lateral collateral ligament. Meniscus injury is a very important structure in the knee joint, due to its poor blood supply, a large tear injury is very difficult to complete self-repair. The broken meniscus is constantly rubbed by the femur in the knee joint, which tends to increase the size of the rupture on the one hand, and the uneven meniscus on the other hand will in turn wear down the cartilage on the surface of the femur, which will form osteoarthritis over time. At the same time, if the meniscal rupture is too large, the torn portion may even flip up in its entirety and get stuck in the middle of the knee joint, causing severe pain and joint entrapment. Therefore, meniscal injuries that occur in the central 2/3 of the meniscus or where the tear is large and displaced should be treated early with arthroscopic surgery, while peripheral meniscal injuries that are not displaced can be treated conservatively with braking. Anterior cruciate ligament (ACL) injuries play a very important role in maintaining the stability of the knee. After an ACL injury, the stability of the knee joint can be greatly affected. This instability can lead to wear and tear of the articular cartilage. At the same time, an unstable knee joint becomes extremely fragile during strong confrontational sports such as soccer and basketball, and is prone to more serious injuries. Therefore, most ACL injuries require arthroscopic ligament reconstruction surgery. Patellar dislocation can occur insidiously and can even be dislocated and reset in an instant. Patients just feel their knee sliding and it is easy to ignore it. If the dislocation is not reset on its own, the knee joint will be painful and swollen, and it needs to be reset in the hospital, and after reset, it needs to be fixed in a cast or brace for 4 weeks, and then gradually exercise the knee mobility and muscle strength exercises. If the patellar dislocation is recurrent, it is often related to the patient’s poorly developed femoral slide structure, poor patellar trajectory and poor lower limb rotational force line, etc., which requires surgical treatment. 3, rotator cuff injury Rotator cuff injury often occurs at the humeral stop site, where blood flow is poor, and it is difficult to heal by itself after the injury, the injury is not large enough to maintain normal function temporarily under the compensation of the surrounding muscles, but with the shoulder joint activities, the rotator cuff rupture will be bigger and bigger under the continuous friction; just like the torn clothes, without sewing, the mouth will tear bigger and bigger. Eventually a huge rotator cuff rupture can cause severe functional impairment and unrelieved pain. If the injury is not large, you can perform physical therapy such as periacetabular muscle training and assisted shock wave, but conservative treatment for a period of time if the symptoms cannot be relieved or the rotator cuff tear has a tendency to increase should be treated by arthroscopic surgery. Shoulder dislocation is more common in basketball, volleyball and other sports, and can be associated with a variety of combined injuries to the structures around the shoulder joint. The initial dislocation of the shoulder joint needs to be repositioned promptly by manipulation, which should be done under anesthesia. After repositioning, a mild external rotation brace should be fixed for 3 weeks to facilitate the healing of the glenoid ligament tissue, and then shoulder mobility and muscle strength exercises should be started. The second and subsequent dislocations often become easier. Repeated dislocations will make the joint capsule more and more relaxed and easier to dislocate. Repeated dislocations of the shoulder joint are very damaging to the articular cartilage and cause fear to the patient’s psyche, so recurrent dislocations require surgical treatment. Through the above explanation, we can easily see that although the pain of sports injury will be relieved quickly, the damage to joint cartilage, ligaments and other structures is very difficult to be detected at first. Therefore, we hope that we can strengthen our awareness of sports protection, and once the injury has occurred, we should ask a professional sports medicine doctor to assess the condition and develop a scientific rehabilitation and treatment plan, so that we can get a better post-injury rehabilitation and return to the sports field with more confidence in the future.
