Achilles Rupture in the Setting Posterior Tibial Osteochondroma: A Case Report and Guidelines for Management of Osteochondromas Adjacent to Tendons.

The resultant injury is likely due to mechanical irritation at the tendon site, which caused wear over time and eventual acute rupture.

Therefore, we conclude that it is reasonable to counsel patients with known osteochondromas in this location due to the risk of possible Achilles injury, particularly if at all symptomatic.
