Osteochondroma of the distal tibia complicated by a tibialis posterior tendon tear.

Osteochondroma of the bone can irritate the overlying soft tissue, resulting in pain and discomfort. Rarely, a tendon tear can occur by an impinging bony mass. We report a case of osteochondroma of the distal tibia in a 23-year-old female patient that was complicated by a partial tear of the tibialis posterior tendon. She was treated with excision of the bony mass combined with tendon debridement and repair. The follow-up examination at 5 years postoperatively showed successful results.
