Ankle sprain
Did you know that an ankle sprain is one of the most common injuries in the world? It is estimated to account for nearly 20% of all sports injuries, affecting both elite athletes and everyday people. Simply walking on uneven ground or making a wrong move can be enough to cause this injury. A quick diagnosis is essential to adapt the treatment and prevent recurrences.
What is a sprain?
A sprain occurs when one or more ligaments of the ankle are excessively stretched or torn. It generally happens during a misstep, with a foot inversion or twist, leading to joint destabilization. Unlike a strain (simple muscle stretch) and an fracture (bone break), a sprain affects the ligament structure, notably the lateral collateral ligament, which is often involved. This ligament injury can lead to joint instability requiring appropriate management, just like other ankle conditions such as ankle cysts.
Symptoms and Severity Grades
When a sprain occurs, the foot twists abruptly (usually in inversion), stretching or tearing the lateral ligaments; the injury is so common that it is one of the main reasons for emergency consultations. The body's immediate reaction is a rush of blood causing swelling, warmth, and visible bruising within minutes; these are the result of deep bleeding linked to ligament tears. These symptoms are commonly referred to as a painful ankle.
In a grade 1 sprain, the injury is limited to a simple stretching: the pain remains bearable, mobility is almost normal, and a functional bandage is usually sufficient, with weight-bearing generally possible with caution. In grade 2, the partial tear causes acute pain that increases with movement, significant swelling with a hematoma, and makes walking difficult; a splint or walking boot is then recommended to protect healing. Grade 3 corresponds to the complete rupture of one or more ligaments: the joint becomes unstable, the ankle swells all around, bearing weight becomes impossible, and associated injuries (nerves, cartilage) are not uncommon, explaining the intense pain and the risk of prolonged aftereffects or even reparative surgery.
Thus, from a simple stretch to a complete rupture, the clinical progression reflects the increasing extent of the injuries: the more the ligament structure is torn, the more pain, swelling, bruising, and instability increase, delaying weight-bearing and prolonging the functional rehabilitation needed to restore proprioception and prevent recurrence. In severe cases, chronic ankle instability may develop.
Diagnosis and Examination Methods
The evaluation of an ankle sprain begins with a thorough medical history, during which the practitioner asks the patient about the circumstances of the accident, the symptoms experienced, and the medical history. This step helps to better understand the mechanism of the trauma and to guide the clinical examination.
During the physical examination, the healthcare professional observes the ankle for signs such as pain, swelling, bruising, or limited movement. They also assess the stability of the joint by performing specific tests.
Among these, the anterior drawer test is commonly used to detect laxity of the anterior talofibular ligament, indicating a possible sprain. This test consists of stabilizing the leg while pulling the heel forward; excessive movement of the talus relative to the tibia suggests a ligament injury. Some patients with constitutional joint hyperlaxity may present natural laxity, which should be differentiated from a true sprain.
To rule out a fracture, radiographs are often prescribed. These criteria help determine the need for imaging based on pain and the ability to bear weight. Although X-rays are effective for identifying fractures, they do not allow visualization of ligament injuries.
In this case, ultrasound is the examination of choice to assess the integrity of the ligaments, offering a dynamic and precise analysis of soft tissue structures. In case of doubt or suspicion of more complex injuries, an ankle MRI can be performed to obtain a detailed visualization of the soft tissue, tendons, and cartilage. Thus, an approach combining medical history, clinical examination, and appropriate imaging allows for an accurate diagnosis and helps determine the most appropriate management for an ankle sprain.

Treatment Options and Care
The treatment of an ankle sprain depends on its severity and aims to relieve pain, promote the healing of injured ligaments, and prevent complications. For mild sprains, the initial approach is based on the PRICE protocol, which includes protecting the ankle, resting, applying ice, compression, and elevating the limb. These measures help to limit inflammation and relieve pain.
Depending on the severity of the sprain, immobilization may be necessary. This can be done with a semi-rigid splint or a brace, allowing the joint to be stabilized while still permitting some mobility. In more severe cases, a cast or orthopedic boot may be required to completely immobilize the ankle. Ankle cast immobilization remains an important therapeutic option in certain cases.
Rehabilitation with a physiotherapist plays an important role in recovery. It includes exercises aimed at restoring mobility, strengthening the periarticular muscles and improving proprioception, i.e. the awareness of the ankle’s position in space. This rehabilitation reduces the risk of recurrence and helps restore normal ankle function. In some cases, ankle and foot injections may be recommended to relieve persistent pain.
In cases of severe sprains, especially grade 3 sprains with complete ligament rupture, surgical intervention may be considered. This option is generally reserved for patients with chronic ankle instability or high-level athletes. Surgery aims to repair or reconstruct the damaged ligaments, often using minimally invasive techniques. An ankle ligamentoplasty or an ankle ligament surgery may be necessary to restore joint stability.
Prevention and Post-Treatment Rehabilitation
Before any sports activity, a complete warm-up is essential. It increases body temperature, loosens the muscles and joints, thereby reducing the risk of injury. Light cardiovascular exercises, dynamic stretching, and movements specific to the practiced sport are recommended to effectively prepare the body for exertion.
The choice of equipment is equally important. Wearing suitable shoes for the activity ensures good support and adequate shock absorption.
In cases of joint fragility, using an ankle brace can provide additional support and help prevent sprains. An external ankle sprain strapping may also be recommended to stabilize the joint when resuming sports activities.
Post-injury rehabilitation should be supervised by a healthcare professional, such as a physiotherapist. They will develop a personalized program including muscle strengthening exercises, proprioception improvement, and restoration of joint mobility. Tools such as the proprioception board can be used to work on balance and coordination, which are essential for a full recovery and the prevention of relapses. The 5 exercises for ankle rehabilitation are particularly effective for regaining strength and stability.
