[Osteochondritis Dissecans of the Talus with Hindfoot Malalignment--Autologous Matrix-Induced Chondrogenesis with Lateral Calcaneal Distraction Osteotomy in an Internationally Successful Young Female Ski Racer]

Abstract

Background: Osteochondritis dissecans of the talus (ODT) describes a special entity of osteochondral lesions of the talus (OLT). In the case of an advanced stage or failure of conservative treatment, a wide variety of surgical treatment strategies for osteochondral defects of the ankle have been described. In most cases, the ODT leads to a loss in sports time and competition.

Material and methods: In the following case report we describe a case dealing with a young alpine ski racer who competes in international races. An osteochondritis dissecans of the talus was observed and led to pain and loss of sports function. We decided for an operative treatment with an autologous matrix-associated chondrogenesis (AMIC). In addition to the AMIC we performed a lateral calcaneal distraction osteotomy, based on the findings of a flatfoot in order to correct the hindfoot malalignment.

Results: At an early time pain relief could be detected. Step by step, the presented ski racer could increase the intensity of training sessions. Based on the findings in the MRI at the follow-up, an integrated repair tissue could be detected.

Conclusions: The following case report describes a positive course after an autologous matrix-associated chondrogenesis (AMIC) combined with a lateral calcaneal distraction osteotomy. At this time the athlete is reintegrated in elite sports and takes part in the normal training programmes.
