Mosaicplasty for the treatment of osteochondritis dissecans following Legg-Calvé-Perthes disease: a case report and literature review

Legg-Calvé-Perthes disease leads to hip joint deformity. Osteochondritis dissecans following Perthes disease (OCDP) is a less common entity. Treatment options of OCDP are limited. Osteochondral autologous transfer (OATS) is an established method of treatment of full thickness cartilage defects in different locations. This paper presents the case of a 42-year-old patient diagnosed with symptomatic OCDP and treated with lesion fixation using autologous osteochondral grafts via surgical hip disloca- tion. At the most recent follow-up, 5.5 years after the surgery, the patient did not complain of any pain during rest or activity. He had painless motion with persisting abduction and internal rotation reduc- tion. Harris hip score (HHS) improved from preoperative 62 to 92 points at most recent follow-up. Treatment protocol was discussed in relation to the literature regarding this clinical topic.
