Arthroscopic Implantation of Minced Cartilage From the Os Trigonum and Posterolateral Process of the Talus: Single‐Stage Cell‐Based Treatment of Osteochondral Lesion of the Talus

The best surgical treatment of osteochondral lesion of the talus (OLT) remains controversial. Among the available surgical procedures for OLTs, implantation of the minced cartilage from the talar lesion is a promising cell‐based technique. However, surgeons may experience difficulties when enough volume and quality of the cartilage cannot be obtained from the talar lesion. In addition, some patients such as athletes simultaneously suffer from both OLT and posterior ankle impingement syndrome. This article describes the possibility of implantation of minced cartilage from the Os Trigonum and/or posterolateral process of the talus to treat OLTs. Furthermore, this technique can simultaneously treat both the OLT and posterior ankle impingement syndrome in a single stage with a minimal risk of donor‐site morbidity. Considering the low morbidity related to harvesting even asymptomatic Os Trigonum and/or posterolateral process of the talus, this technique might be a valid option for chondral lesions in other joints.
