20 years old female: two years before, successful debridement of a medial talar ocd.
Currently, posteromedial ankle pain with FHL tendinitis. CT scan shows a rod-shaped bony fragment.

Picture 1: CT scan showing a rod-shaped loose body

Picture 2: The loose body may have originated from the talar ocd and has probably accidently been detached during the previous arthroscopy and "lost" posterior.

Picture 3: Posterior arthroscopy: the loose body (1) was found to be situated against the FHL tendon, resulting in mechanical irritation of the tendon (2) = Level of subtalar joint.
