The ankle joint is the part of the lower leg that connects to the foot. It is made up of the larger tibia and the smaller fibula of the lower leg together with the talus on the heel, and bears the most weight during sports, often with the strongest impacts and torsions, making ankle injuries the first of all sports injuries to occur. Almost everyone will suffer at least one ankle injury in their lifetime. Ankle injuries can occur for a variety of reasons, starting with their own. Fatigue, degeneration of muscle ligaments, lack of proper preparation before exercise, etc. Wearing inappropriate shoes can also increase the chance of ankle injuries, such as high heels. Then a sprain of the ankle can occur if not properly protected from unusual external forces. Ankle injuries can be mild or severe, and the mild ones tend to be strained ligaments on the outside of the ankle, which are the most common. It is basically caused by an extreme inversion of the foot to the inside and manifests itself as swelling on the outside of the ankle. This type of injury often heals well with conservative treatment. Early mild sprains should also be taken seriously, and it is a good idea to take your doctor’s advice and go to the hospital for a radiograph to rule out fracture dislocations and very serious types of ligament injuries. Usually in the acute stage the doctor will advise the patient to apply cold compresses to the sprained area, elevate the injured foot as much as possible, apply compression bandages with elastic bandages, and immobilize the patient in a plaster cast or brace if necessary. Severe peri-ankle ligament injuries require close attention and regular follow-up in the hospital after the acute phase. Some patients with severe ligament injuries have poor healing of the ligaments and are prone to ankle instability if the ligaments do not reach their proper strength. Ankle instability in turn leads to recurrent ankle sprains and degenerative osteoarthritis of the ankle joint, which can be accompanied by or secondary to ankle cartilage injuries, resulting in chronic pain. For chronic ankle instability, MRI, or Magnetic Resonance Imaging, can reveal the site of ankle ligament damage more clearly. Ankle arthroscopy is a minimally invasive examination and treatment tool that can reveal the extent of cartilage damage in the ankle joint and also visualize the extent of ligament damage and treat it minimally invasively. Severe ankle instability often requires early surgical treatment to repair and strengthen damaged ligaments and repair damaged ankle cartilage. Prolonged ankle instability may result in deformity of the ankle, at which point osteotomies for orthopedics or artificial ankle replacements are required. If the violence of the injury is further increased, it is usually some kind of car accident, strenuous sports injury, etc.. This type of injury is very violent and often results in a fracture of the ankle, either the inner or outer ankle, or both ankles or even all three ankles, dislocation, comminuted fracture, and so on. If the fracture is a very minor cleavage fracture without any displacement, it can be treated conservatively with immobilization such as casts or braces. If the fracture is displaced then surgery is necessary to first set the fracture and then immobilize it with screws and splints. Ankle fractures require a very high degree of repositioning and fixation, and the slightest malalignment may lead to poor joint alignment, which in turn increases the likelihood of osteoarthritis of the ankle joint. Therefore, some complex ankle fractures are a serious challenge for surgeons. Complete healing of ankle fractures and ligament injuries often takes a long time, and it is important to work with your surgeon during the rehabilitation process.
