We thank Dr. McKee for his comments regarding our article.
With regard to the first question, we would like to specify that all of the patients were treated six months or more after their injury. The results reported in Table I were derived from a normal statistical elaboration of a numerical sequence. For greater clarity, here we report the numerical sequence from which the datum reported in Table I, related to Group 3, was drawn. The patients in that group were treated at Months 6, 8, 12, 6, 7, 8, 8, 9, 10, 6, 12, 6, 6, 7, 22, 7, 23, 6.5, 21, 17, 7, 21, 7, 6, 6, 7, 6, 17, 6, 7, 7, 9, 21, 26, 6, 7.5, 6, 6, 6, 7, 23, and 10, resulting in a mean value of 10.2 months and a standard deviation of 6.1 months.
With regard to the second question, we agree with Dr. McKee. A mistake occurred during the revision process, and an erratum appears in this issue of JBJS, as described in my reply to the previous letter.
