Background:
The long term results after using the iliotibial band autograft
(
ITB) are not fully known. If equal in quality to conventional methods the ITB
graft could be a useful alternative as a primary graft, and in revision surgery or
multiligament reconstruction.
Purpose / Aim of Study:
To assess whether the ITB-autograft is a long term
reliable alternative to the BPTB- autograft, using a prospective randomized
controlled trial design
Materials and Methods:
From 1995-1996 sixty subjects scheduled for
primary ACL- reconstruction were included in a prospective randomized
controlled trial. Three senior knee-surgeons, experienced in both types of
ACL- surgery, performed all the operations. A standardized and supervised
rehabilitation program was used for both groups for 6 months. 30 patients
received the ITB-reconstruction, and 30 received the BPTB-reconstruction. 49
participated at follow-up in 2010 (82%). Primary outcome was the failure-rate.
Secondary outcomes were KOOS (pain, symptoms, Sport/Rec, QOL, ADL),
Tegner Activity Scale, AKP-score, Lysholm Score, Rolimeter laxity, extension
deficit, single-hop and crossover-hop for distance.
Findings / Results:
At 15-year follow-up no differences existed between the
groups. Graft failure occurred in 3 BPTB-subjects (12.5%) and 4 ITB- subjects
(16%) (
P=0.53).KOOS Sport/Rec score for the BPTB-group was 73, and 75
for the ITB-group (P=0.82). The KOOS QOL score was 68 and 72 for the
BPTB-group and ITB-group, respectively (P=0.58).
Conclusions:
We found similar graft-failure-rates and KOOS-scores when
comparing BPTB- and ITB-operated individuals, at 15-year follow- up. The
ITB graft had equal long-term results compared to the BPTB graft and is
recommended as a reliable alternative autograft for ACL-reconstruction.
