Peroneal tendonitis is characterized by structural irregularities of the peroneal tendon as a response to load. The swelling is brought about by irritation of the tendon and adjacent structures, but it is not a vital feature of the condition.
What are the causes?
Various factors that can lead to peroneal tendonitis include the following:
- Muscular imbalances in the lower part of the limb
- Abrupt increase in weight bearing activities especially running, walking or jumping
- Inadequate or less supportive footwear
- Incomplete rehabilitation after an acute injury of the ankle such as a sprained ankle
- Poor biomechanics of the lower region of the limb
An individual with peroneal tendonitis might experience the following:
- Pain or discomfort during and/or after engaging in weight bearing activities
- Steady worsening of pain over the exterior of the ankle
- Discomfort when turning the foot in and/or outwards
- Instability surrounding the ankle during weight bearing
Management of peroneal tendonitis
The diagnosis of the condition tends to vary depending on the phase of the injury.
During the acute phase, there should be an improvement within a couple of weeks of treatment. This involves minimizing the load and allowing the irritated tendon to rest. When the discomfort subsides, an exercise regimen at home is started to restore normal range of movement, restore the strength of the lower limb muscles as well as improve balance.
There are several measures that can help lower the risk for developing peroneal tendonitis such as:
- Wear the right, supportive footwear
- Maintain a level of activity during the “off-season”
- Steadily increase the exercise level or training load
- Cross training is not only ideal in maintaining heart health but also ensure that the muscles remain strong and lower the risk for re-injury when returning to sport
- Improve balance and ankle proprioception
