We aimed to quantitatively assess the outcomes of studies, comparing the use of Bone-patellar tendon-bone (BPTB) and the quadriceps tendon-bone (QTB) autografts when reconstructing the anterior cruciate ligament (ACL).
MEDLINE, Embase, and CINAHL databases were searched for relevant articles published between January 1980 and January 2015 for the purpose of identifying studies comparing BPTB and QTB autografts for ACL reconstruction. Included studies were assessed regarding their methodological quality before analysis. Outcomes analyzed were graft failure rates, objective and subjective stability assessments, as well as the presence and severity of donor site morbidity.
Five studies contributed to the quantitative analysis of 806 patients with 452 patients included in the BPTB group and 354 patients in the QTB group. Graft failure rates were similar between the 2 groups [odds ratio (OR) = 0.61; confidence interval (CI) = 0.17-2.15; Z = 0.78, P = 0.44]. There were no significant differences between the 2 groups when testing anteroposterior stability using an arthrometer (standardized mean difference = 0.07; CI = −0.12-0.25; Z = 0.70, P = 0.48). At 1 year postoperatively, there was no difference in the percentage of patients with a positive pivot shift test between the 2 groups (OR = 1.0; CI = 0.85-1.18; Z = 0.01, P = 0.99). However, significantly less patients had graft site pain 1 year after surgery in the QTB group (OR = 0.10; CI = 0.02-0.43; Z = 3.12, P = 0.002). Similarly, fewer patients reported moderate to severe pain while kneeling, in the QTB group (OR = 0.16; CI = 0.07-0.37; Z = 4.26, P < 0.001).
This study demonstrates comparable survival rates and joint stability when BPTB and QTB grafts are used. However, fewer adverse donor site symptoms are evident with QTB grafts.
