Arthroscopic one-piece excision technique for the treatment of symptomatic lateral discoid meniscus.

We introduce a new arthroscopic technique for the partial excision of the symptomatic lateral discoid meniscus in one piece. Our experience indicates that this technique has several advantages compared with the conventional surgical techniques of partial meniscectomy. The operating time is short (less than 20 minutes), it is less aggressive, there is less damage to the cartilage, and less formation of foreign bodies.
