Incomplete tears identified from an MRI may initially be treated with early rehabilitation. Nonsurgical treatments may include the use of crutches, ice, and anti-inflammatories to rest and restore the ankle over time. These nonsurgical methods work in many cases, though they can occasionally increase your chances of re-rupture and can result in longer recovery times compared to surgical restorations of the ankle.
In cases where surgery is recommended, a small incision in the back of your lower leg and stitches the tendon together, repairing it. In some cases, this repair is reinforced with other tendons as well to strengthen the ankle and leg. Afterward, there will still be a period of rest and rehabilitation, though most patients are able to return to regular activity within four to six months after surgery.
