To The Editor:We read with interest the excellent article "Anterior Cruciate
Ligament Reconstruction: Bone-Patellar Tendon-Bone Compared with Double
Semitendinosus and Gracilis Tendon Grafts. A Prospective, Randomized Clinical
Trial" (2004;86:2143-55),
by Aglietti et al. However, we feel that it cannot be described as a
"randomized" trial. Randomization was achieved by a
"strictly alternating" pattern of treatment allocation, which is
open to sources of potential bias. Despite this method of allocation, the two
groups are very well matched, although there is no discussion in the article
as to whether a stratification process was used to achieve this.
