Essentially, the ankle consists of three bones, the tibia, fibula and talus, all held together by thick fibrous ligaments. The bottom parts of the tibia and fibula (shin bones) join together and surround the talus in such a way that it is able to rock forwards and back while providing stability and restricting the side-to-side movements.
The ligaments holding the tibia and fibula together are large and thick, forming a syndesmosis. An injury to this area is known as a high ankle sprain.

Anterior ankle impingement is a condition where repetitive forces compress and damage the tissues at the front of the ankle, causing pain and inflammation. It is a common injury that can affect people of all ages, however is usually seen in athletes of sports involving repetitive or forceful upward movements of the ankle, such as sprinting, landing from long jump, uphill and downhill running.

What are the symptoms?
Pain at the front of the ankle joint is the primary symptom of anterior ankle impingement. This can be felt as an intense, sharp pain occurring with ankle movements or a dull ache in front of the ankle following periods of exercise. Pain can also be felt when putting weight through the ankle while standing, walking or running. Night soreness, stiffness, swelling and reduced ankle flexibility are also common symptoms. 
 
How does it happen?
Anterior ankle impingement is caused by traumatic or repetitive compression to the structures at the front of the ankle as the tibia and talus move towards each other during ankle movements. The tissues that are affected become damaged and inflamed, causing the pain typical of ankle impingement. Chronic inflammation can lead to further stiffness, exacerbating the impingement process.
 
The most common risk factor for ankle impingement is a previous ankle sprain that was not adequately rehabilitated, as this can result in a stiff or unstable ankle. Another cause of impingement is the growth of small osteophytes or bony spurs around the ankle joint that press against the nearby soft tissues. These can be due to osteoarthritis or grow as a reaction to previous injury.  Training errors, muscle tightness, unsupportive footwear and a hypermobile ankle have also been shown to be risk factors for anterior ankle impingement.
 
How can physiotherapy help?
Depending on the cause, mild cases of anterior ankle impingement usually recover in one to three weeks with rest and physiotherapy treatment. For more severe impingement, the ankle may require up to six weeks of rest and rehabilitation to recover. In rare cases, surgical intervention will be required to remove any physical causes of impingement such as osteophytes, to restore impingement free movement of the ankle.

Your physiotherapist will first identify the cause of your ankle impingement and help you to choose the best course of action to reduce your symptoms. They are able to advise you on the appropriate amount of rest and provide stretches and exercises to restore strength and flexibility to the ankle.

Mobilization techniques and range of motion exercises can also reduce stiffness of the ankle, restoring normal joint movement. Balance and proprioception exercises are also included to help prevent further ankle injury. 

Physiotherapy treatment is definitely the first step before considering surgery. If surgery is required however, your physiotherapist can help you to make a full recovery with a post surgical rehabilitation program.

Chronic ankle instability, as the name implies, is a chronic condition of instability affecting the ankle and it’s surrounding structures. It usually develops after a severe ankle sprain. However, some people are born with less stable ankles and these individuals are generally extra flexible throughout their bodies. Approximately 20% of ankle sprains lead to chronic ankle instability due to the resulting changes in ligament support, strength, postural control, muscle reaction time and sensation. 

What are the symptoms?

As well as being more susceptible to ankle sprains, people with chronic ankle instability may notice they feel cautious during high-intensity activities, running on uneven surfaces or when changing directions quickly. They may experience a sense of weakness or frequent ‘giving way’ around their ankle.

What are the causes?

The primary causes of this condition are ligament laxity, decreased muscle strength of the muscles surrounding the ankle and reduced proprioception. 

Following an ankle sprain, ligaments can be stretched and slightly looser than they were. In severe cases, they may have torn altogether, leaving the ankle less structurally sound. Without full rehabilitation, the surrounding muscles also become weaker and studies have shown that balance and sensation of the ankle can also be reduced. This means that the ankle is more likely to be injured again, creating a cycle of recurrent injuries, leading to further instability.

How can physiotherapy help?

Physiotherapy treatment for chronic ankle instability focuses on improving strength, control and balance with a variety of techniques and exercises. This approach can significantly improve ankle stability and reduce the risk of future sprains. Physiotherapists can help patients to regain confidence and get back to their best performance. 

In some cases, braces for support can be used. However, this can lead to dependence and further loss of strength and control if used unnecessarily. In cases of extreme ligament laxity or if physiotherapy fails, surgery to repair the damaged ligaments is considered. This is usually combined with a full physiotherapy rehabilitation program for greatest success.

Why are ankles particularly vulnerable to injuries related to poor balance?
 
Our ankles have to support our entire body weight when standing on one foot. To provide us with agility as well as stability, our ankles have the ability to move from side to side as well as backwards and forwards. There is a complicated process constantly operating to keep your foot in the correct position while supporting all this weight, particularly with quick changes of direction, activities done on tiptoes, jumping and landing.
 
If the ankle rolls excessively inwards, the ligaments on the outside of the ankle can be damaged and torn. Balance is an important part of keeping the ankle in the correct alignment and not twisting too far to either side during challenging activities.
 
A study of high school basketball players  by Timothy McGuine et al. in 2010 showed that students with poor balance were up to seven times more likely to sprain their ankle than students with good balance. Other studies have shown that balance training is an effective way of preventing falls in elderly populations.
 
Balance can vary from one leg to the other.
 
Most of us tend to favour one side of our body for all activities. This is more obvious in the upper body, with most of us identifying as either left or right handed. The same is also true for our lower body, with each of us favouring one leg over the other for balance activities. This can mean that one leg has better balance and strength than the other, leaving one leg more vulnerable to injury.
 
Reduced balance can mean your body has to work harder to perform activities, with muscles activating in a less coordinated way. Improving your balance can also improve your body’s efficiency of movement, which can, in turn, improve your overall performance without actually improving your muscle strength.
  
Balance can be trained rapidly.
 
Balance is one of the most overlooked dimensions of physical health however, the good news is that it can be improved relatively quickly. Do a quick check to see if you can stand on each leg for two minutes with your eyes closed. If this is difficult you might find that improving your balance is a great next step in your training program.
 
Your physiotherapist is able to identify any deficits in your balance is and is able to develop a training program for you to improve it. Come and see us for an appointment to see how we can help.​
