The two main aims when treating Achilles tendonitis are to reduce the strain upon the tendon, and to reduce inflammation.
To reduce strain, activities which aggravate the condition will need to be limited or avoided for a period of time. Orthotics (corrective devices worn in the shoe) may also assist in reducing pressure on the tendon.
Inflammation may be addressed by taking anti-inflammatory medications, applying ice packs (for 20 minutes per hour during the acute stages of injury), and in more severe cases, minimising movement of the foot and ankle via the use of a restrictive cast or boot for a period of approximately 8 weeks.
Specific exercises which focus on gently stretching the calf muscle can be introduced once the acute stage of inflammation has passed.
Surgery is considered as a last resort for the treatment of severe cases of Achilles tendonitis, and is necessary if the tendon needs to be re-attached. Rehabilitation after surgery will generally allow return to normal activity within a period of 10 weeks, and to competitive sports in approximately 3 to 6 months.
