This disertation presents a comparative analysis of results after ALC
reconstruction using two implant types for suspensory graft fixation
in the femoral tunnel. Injury to the anterior cruciate ligament (ACL)
of the knee is the most common ligament injury that requires
operative treatment. Patient treatment can be non-operative and
operative. So far, multiple ACL reconstruction techniques using a
variety of graft types and implants that fixate the grafts have been
described. Since 1995, titanium buttons with a loop have been used as
implants for suspensory fixation of the graft in the femoral tunnel
during ACL reconstruction. There are two types of titanium buttons
in use: one with a fixed-length loop and the other with an
intraoperative adjustable-length loop. The post-operative knee
stability in this disertation was assessed 24 months after surgery using
the Lachman test and the lateral pivot shift test, as well as the KT-
1000 arthrometer test. In patients whose graft was fixated us...ing a
fixed-length loop implant, the mean post-surgery knee stability,
measured with the KT-1000, was 1.27 +/-0.775; in patients whose
graft was fixated using an adjustable-length loop implant, the mean
value was 1.30+/-1.032 (P=0.691). The mean post-surgery IKDC
score for the fixed-length loop group was 85.704 +/-7.792, while for
the adjustable-length loop the score was 87.524 +/-6.7708 (P=0.233).
The mean Lysholm score was 93.36+/-5.945 for the fixed-length loop
group of patients and 92.68 +/-5.266 for the adjustable-length loop
group (P=0.395). The mean Cincinnati score for the fixed-length loop
group was 90.64 +/-7.030, while for the adjustable-length loop the
score was 90.50 +/-8.906 (P=0.846). The mean Single leg hop test
was 114.074+/-2.20 for the fixed-length loop and 113.094+/-2.192 for
the adjustable length loop group (P=0.5). The results of this study
lead to a conclusion that both types of implants can be used with
success during ACL reconstruction, because the functional results of
operative treatment of ACL reconstruction using both implants were
identical after surgery.
