Instability of the ankles21. 06. 2022.
Ankle injuries are common in sports. They are responsible for 15% to 20% of all sports injuries. Ankle ligaments are especially vulnerable in sports that include frequent, fast direction changes, jumping, and contact. Ankle injuries are common in sports such as soccer, basketball, and volleyball.
Re-ankle injuries are prevalent, especially among athletes. Within three years, athletes account for 73% of all ankle injuries. Walking and jogging pain, considerable edema, and ankle instability are common complaints. Chronic ankle instability is caused by insufficient therapy. Ankle sprains become chronic in 20% of cases. Chronic ankle instability has the same symptoms as a sprain, but it is more severe.
When walking, the ankle joint transfers body weight. Upper and lower ankle joints the upper ankle joint is an angular joint that can only move up (dorsiflexion) or down (plantarflexion), but the lower ankle joint can rotate.
Lower leg tendons connect to foot bones. Muscle contractions move the tendon, which moves the ankle joint. Foot sprains damage ligaments that have been weakened. Ankle fractures can be caused by rotational stresses.
If he does not receive enough therapy or has many sprains, the ligaments will deteriorate, resulting in ankle instability. Ankle instability is frequently treated surgically to relieve persistent pain and function loss.
- Chronic instability is defined by reoccurring ankle sprains or symptoms that last at least a year. CLAI is caused by two factors that frequently coexist:
- Mechanical instability includes ligament laxity, structural ligament abnormalities that affect arthrokinematics, pathological lethargy, disordered joint kinematics, and degenerative joint changes (mechanical CLAI).
- Functional instability impairs proprioception, weakness, and neuromuscular coordination (functional CLAI).
Chronic ankle instability is caused by ankle sprains or abnormalities. It is distinguished by a significant ankle distortion that does not heal and lesser distortions that increase instability. Ankle distortion is more common when the foot is in plantar flexion and inversion, causing ligament injury. Internal rotation could also help. The anterior talofibular ligament is the most damaged by deformation. Ankle injuries occur during activity at low weights but not when fully loaded.
THE BIOMECHANICS OF INJURY
When a ligament near a joint is injured, the musculoskeletal system of the leg changes. In this strategy, the body “protects” the wounded joint. Lower leg muscles become less active to “protect” the joint from stress, while opposing leg and torso muscles become more active. Muscle activity, ligament, and joint capsule injuries all have an impact on proprioceptors, which are required to recognize body position, touch, pressure, and leg load.
Injury to these sensitive tissues makes standing and moving difficult, exposing the foot and ankle to further injury. Our bodies aren’t conscious of ankle load. Injuries and sprains are possible. Each additional injury increases the risk of joint degeneration by 20-30%. Joint cartilage, ligaments, capsule, muscles, and tendons can all be damaged. Injured ligaments heal with a scar, and damaged tissue is weaker and less robust than the original. Repeated injuries result in further damage, decreased ankle stability, and joint instability.
Chronic ankle instability develops after numerous ankle sprains that do not heal within 6 weeks. Instability and sprain symptoms are connected. Chronic ankle instability caused by ligament laxity results in loss of joint proprioception, muscle weakening, and joint degeneration. Chronic instability may result in chronic or post-exercise edema. Uneven surfaces weaken the stabilizer, which might lead to an ankle re-sprain.
People with ankle instability often feel as if their ankle isn’t holding them up, especially when subjected to heightened stressors such as going downstairs or up a hill, landing on an injured leg, landing on the side, ankle rotations, and so on. A drooping ankle is typical.
Patients endure ankle leakage, weakness, and edema. When such symptoms occur, especially if ankle injuries are common, we recommend an orthopaedic evaluation. The outer of the ankle and foot swells and pains after the injury. Some people cannot walk normally without pain. Bruising and blue-green skin will result. Pain spreads from the exterior ankle bones to the internal ligaments and tendons. Patients suffering from this condition are continually concerned that their ankle will twist, resulting in an “unstable” ankle. Chronic ankle pain ensues.
Several techniques can be used to detect recurrent ankle instability. Chronic instability is unpredictable. Medical history and injury history, as well as physiotherapy examination, aid in diagnosis. First, the ankle’s stability is clinically tested.
Ligament and tendon integrity can be assessed using front drawer and inversion stress tests. In addition to testing, joint, muscular, and neurological function are evaluated.
MRI is used to assess the integrity of bones, tendons, and ligaments. It is a precise diagnostic process. Following an accident, MRI can detect ligament lesions, thickenings, and partial and entire discontinuities.
Ultrasound can identify ligament and tendon injury. Ultrasound is less expensive and radiation-free than MRI. MRI and ultrasound are non-invasive procedures; arthroscopy is.
Arthroscopy entails making microscopic incisions in the joint. This procedure allows us to assess the structural integrity of the joint. Arthroscopy can be used to diagnose and treat injuries.
First, determine the type of ankle instability. Is the patient suffering from mechanical instability, in which the ligaments are clearly wounded and no longer support the ankle’s stability, or functional instability, in which the ligaments are more elastic, but the surrounding muscles and tendons do not provide joint stability?
By fostering neuromuscular coordination, limb posture, and body balance in space, targeted training can help to strengthen weaker muscles and improve joint stabilizer function.
Chronic ankle instability causes joint swelling and soreness after exercise. RICE lowers inflammation and discomfort. Each letter in RICE denotes a stage. Rest, ice, compression, and elevation.
- Rest relieves joint strain and edema.
- Cooling or cryotherapy (ice) alleviates joint pain. To avoid irritation or frostbite, chill the area with cold compresses or ice. To avoid issues, it should not be refrigerated for too long.
- Compression minimizes joint edema. Compression is achieved by using a distal-tightened elastic bandage or orthosis. Through a bandaging action, compression enhances joint stability and minimizes edema.
- Elevating your legs decreases joint swelling caused by gravity. When lying down, a pillow or towel can be used to raise the leg, and when sitting, a table can be used.
- P is used as a precautionary measure. The protection is beneficial for both acute ankle and long-term ankle instability. An orthosis or bandage might help to protect the ankle.
Ankle bandaging helps to support the joint and minimize edema. Bandages can be tight or taped. Bandage in such a way that there are no creases to irritate the skin, but not so tightly that circulation is restricted. Bandage re-injury-prone activities.
