EDITOR'S NOTE: The corresponding author was asked to respond to this letter, but to date (December 13, 2005) has not done so.

To The Editor:

In the article “Physeal sparing reconstruction of the anterior cruciate ligament in skeletally immature prepubescent children and adolescents” by Kocher, et al, a post-operative MRI scan of the knee was presented (figure 2). The authors stated that this was a STIR (short-tau-inversion-recovery) sequence, but I think they were mistaken.

In a STIR sequence there should be good fat suppression, which is not present on this image. Furthermore the signal to noise of this image is good and I suspect that a completely different sequence was used. I think it important to clarify which MRI sequence was used so that other institutions can reproduce similar satisfactory post-operative images.
