In order to determine the effectiveness of a new technique of rectus f
emoris transfer and to compare the effectiveness between the two trans
fer sites (gracilis versus sartorius), we evaluated the results of pre
-and post-operative gait analyses in 46 limbs in 35 cerebral palsy pat
ients who had been treated with the rectus femoris transfer either to
the gracilis (gracilis group) or to the sartorius (sartorius group). P
reoperatively, there were no significant differences between the two g
roups in any of the parameters measured. Post-operatively there were s
ignificant improvements in stride length, dynamic knee range of motion
(ROM), knee angle at initial contact, and maximum knee extension in s
tance in both groups (P < 0.05). The improvement of dynamic knee ROM w
as more significant in the gracilis group (11.3 degrees) than in the s
artorius group (5.0 degrees). Postoperatively maximum knee flexion in
swing increased significantly in the gracilis group (P < 0.05), but no
t in the sartorius group. Overall results indicated that the transfer
of the rectus femoris to the gracilis by the technique currently used
was better than that to the sartorius. (C) 1997 Elsevier Science B.V.
