Factors that can contribute to peroneal tendonitis include:
- A sudden increase in training, particularly weight-bearing activities, such as walking, running, and jumping
- Improper training techniques
- Inadequate or unsupportive footwear
There are also some other issues that can increase a person’s risk of developing peroneal tendonitis:
- Higher foot arches/ supinate
- Lower limb muscles and joints not working well together
- Imbalanced muscles in the lower limbs
If someone fails to complete a rehabilitation program following an ankle injury, such as a sprain, they are also more likely to develop peroneal tendonitis.
Over time, the damaged peroneal tendons will thicken as scar tissue tries to repair the damaged area. This makes the tendons weaker and more prone to tearing.
