Arthroscopic findings in the knee in nail-patella syndrome: a case report.

Nail-patella syndrome is a rare genetic disorder that can cause significant morbidity in several organs, including the musculoskeletal system. This case report describes our arthroscopic findings in the knees of an adolescent with bilateral hypoplastic and subluxed patellae. Our findings suggest that early intervention should be considered whenever this syndrome is recognized. This may modify some of the long-term joint problems seen in adults with nail-patella syndrome.
