The peroneal tendons are the two tendons on the outside of the ankle that attach the muscles to the bones. Peroneal tendon problems commonly occur from an ankle sprain. A tear or split in one or both of them can occur after repetitive trauma or overuse.
Surgery is usually not considered for peroneal tendon problems until it has become impossible to control the symptoms without it. In this instance, the tendon tissue can usually be sewn back together with sutures. If more than half of the tendon is torn, the surgeon will perform a tenodesis, cutting the damaged portion of the tendon away and suturing the remaining portion to the other peroneal tendon next to it.
As an alternative, the injured tendon may be repaired through the use of stem cell therapy, using the patient’s own stem cells to heal the injury with a minimally invasive, same-day procedure.
