Infectious Achilles Tendinitis After Local Injection of Human Placental Extracts: A Case Report.

Local injections of corticosteroids or human placental extracts are sometimes used for the treatment of resistant tendinitis or fasciitis. We report a case of infectious Achilles tendinitis complicated by calcaneal osteomyelitis after injection of human placental extracts for the Achilles tendinitis. She was treated with excision of the infected bone and tendon, followed by V-Y lengthening of the proximal portion of the Achilles tendon in a single stage. At 2 years postoperative, she remained symptom free without any signs of recurrence, and the follow-up magnetic resonance imaging scan demonstrated a well-maintained Achilles tendon with normal signal intensity.
