Nail patella syndrome.
A 45 year old male presented to a primary care physician with complaints of long term, bilateral knee and bilateral foot pain, without history of significant trauma. Physical exam demonstrated full range of motion without any erythema or edema. Fingernails were abnormal and hypoplastic. Bilateral knee radiographs demonstrated moderate degenerative changes of the right knee. Small, atrophic patellae were noted to be proximal to their expected location. Two months later the patient returned to his primary care physician for worsening of the knee pain related to cooler outside temperatures. An NSAID had initially relieved the pain but was becoming less and less efficacious. Alternative medications were prescribed to better control the pain. Complaints of continued knee pain and now bilateral hip pain brought him back to his physician four months later. He requested a referral to an orthopedic surgeon and an MR of the right knee was obtained. The finding showed complex tear of the lateral meniscus in patient with Nail Patella Syndrome.
