Abstract

|
|
The objective of this clinical study is to present a new method of preloading a reconstruction at the time of fixation. Traditional concepts of isometry and graft tension on a relatively short graft caused overtensioning of ACI grafts and
resulted
in
erratic healing and ACL loosening. In order to prevent the problem of stretching out of the ACL grafts, 1/3 bone-Achilles tendon autograft, 11 cm in length was used for the ACL graft. Bone block of bone-Achilles tendon autograft was fixed in the
tibial
tunnel with a self-locking method and femordal fixation was done with 100 Newtons of graft force using modified Bunnel wire suture technique over the two femoral screws. The total strain did not exceed 7 %. Of the 100 cases of bone-Achilles
tendon
reconstruction 40 cases (group II) were done with 100 Newtons of graft force setting. KT-100 measurements have been used to document graft tensioning. The immediate postoperative right-left difference was - 3 millimeters which remained -1
millimeter
after one year of remodelling. The graft foce-setting group (group II) resulted in more consistent results. Graft tension could be maintained in full range of knee motion and pivot shifting was not noted. Lachman test was negative in all force
setting
group and only 3 cases of mild anterior drawer signs were noted with concomittant mild pivot gliding. Early need motion exercise after third day of operation was possible and full extension was obtained in a week. Maintenance of graft tension was
important to prevent residual laxity. Both the graft length and thickness was essential to survive the strain of preload and knee motion.
