Background:
Anterior Cruciate Ligament reconstruction (ACLR) with quadri-
cepstendon graft (QTB) has recently shown reduced donorsite morbidity com-
pared to patellatendon graft. Hamstring graft is the most used graft type for
ACLR. It is unknown if QTB graft also reduce donor site morbidity compared to
hamstring graft and whether knee stability and function are similar to hamstring
graft.
Purpose / Aim of Study:
The purpose of this study was to compare clinical
outcome including donorsite morbidity of ACLR using QTB or hamstring graft in
a prospective randomized study. We hypothesized reduced donorsite morbidity
for QTB grafts compared to hamstring grafts.
Materials and Methods:
From 2013-15, a total of 99 patients were included
in the present study. Inclusion criteria were isolated ACL injuries in adults. 50
patients were randomized to QTB grafts and 49 to hamstring grafts. Antero-
posterior knee laxity measured with a KT-1000 arthrometer. Patient evaluated
outcome were performed by KOOS, subjective IKDC score and Tegner function
score. Donor site morbidity was evaluated by the validated ‘‘Donor-site-Related
Functional Problems following ACL reconstruction score and a detailed ques-
tionnaire.
Findings / Results:
Donor site symptoms were present in 30 % of patient in
the QTB group and 52 % of patients in the hamstring group (p< 0.05). The do-
nor site morbidity score was 82 and 74 for the two graft types (p< 0.05). At
one- year follow-up there was no difference between the two groups regarding
subjective patient outcome, knee function and objective knee laxity.
Conclusions:
The use of the Quadriceps Tendon Bone graft results in less donor
site morbidity than hamstring BTB grafts and has similar subjective and knee
stability outcome. The QTB graft could be a better graft alternative for ACLR
than hamstring grafts.
