Familial osteochondritis dissecans associated with early osteoarthritis and disproportionate short stature

• OBJECTIVE: Familial osteochondritis dissecans (OCD) is a rare disorder characterised by disturbed chondro-skeletal development, disproportionate growth and deformation of the skeleton. DESIGN: We identified a five-generation family with 15 living affected members from Northern Sweden. The disorder was diagnosed with a case definition of OCD in at least one joint. RESULTS: Main clinical findings consisted of OCD in knees and/or hips and/or elbows, disproportionate short stature and early osteoarthritis (OA). There were no radiological indications of epiphyseal dysplasia. Anthropometric measurements of affected individuals showed short stature, a high ratio between sitting height and total height, a relatively normal arm span and head circumference. In 12 of 15 cases, onset was during late childhood or adolescence and OA had developed in seven of those patients. CONCLUSIONS: Our observation suggests that OA is a frequent complication in familial OCD even though the lesions appear before closure of physis.
