Description
Hélder Pereira and Takuji Yokoe describe harvesting graft cartilage from a small accessory bone at the back of the ankle to repair cartilage damage on the talus, in a 2026 technical note. The os trigonum, an extra bone present in roughly a fifth of people, and the neighboring posterolateral talar process carry viable cartilage that can serve as an alternative donor. Removing them also treats posterior ankle impingement.
The best candidates have both a talar lesion and a symptomatic os trigonum, though even a silent one can be harvested with the patient's consent. Because the donor site sits outside the load-bearing joint, taking it carries minimal risk of the donor-site soreness that plagues grafts taken from the knee. The harvested cartilage is minced and implanted into the prepared talar defect in the same operation. The authors argue the approach is a valid option worth considering.
