Tibial eminence fracture with meniscal entrapment.

Controversy has existed regarding the treatment of tibial eminence fractures in children. It has been widely assumed that closed manipulation of the knee resulting in radiographic reduction of the fragment is acceptable. We present a case report of a trapped medial meniscus, even after apparent successful closed reduction of an incompletely displaced tibial eminence fracture. The integrity of meniscii cannot be inferred radiographically. Arthroscopic evaluation allows reduction of a trapped meniscus and suture fixation of the fragment is easily accomplished.
