Bone–Patellar Tendon–Bone Autograft Versus Allograft in Outcomes of Anterior Cruciate Ligament Reconstruction

Abstract

Patients undergoing ACL reconstruction with BPTB autografts demonstrate lower rates of graft rupture, lower levels of knee laxity, and improved single-legged hop test results and are more generally satisfied postoperatively compared with patients undergoing reconstruction with allograft BPTB.

Revision Rates After Anterior Cruciate Ligament Reconstruction Using Bone–Patellar Tendon–Bone Allograft or Autograft in a Population 25 Years Old and Younger

“…Allograft ACL reconstruction outcome reports have used hamstring 15,33,34 and BPTB allografts without reporting the type of processing used, 12,35 looked at all types of allografts, 7,25 or lumped all allografts together and failed to report the type of allograft used. [36][37][38] It cannot be assumed that all allografts are equivalent.…”

Objective measurements of static anterior and rotational knee laxity

“…However, two meta-analyses comparing the two main graft types (BPTB vs. ST) have demonstrated that a SSD superior to 3 mm was less frequent in BTPB compared to ST grafts [95,96]. Regarding the use of allografts, some authors reported similar outcomes compared to autografts [97,98], while others suggested that they may be inferior [99]. As for the double-bundle HS autograft technique, there are indications suggesting that it may be superior in terms of sagittal and rotational laxity [100][101][102].…”

Can we predict the size of frequently used autografts in ACL reconstruction?

“…knee pain after BPTB harvest [9,24], higher failure rates and poorer clinical outcome scores associated with hamstring tendon grafts that are less than 8 mm in diameter [8,19,20,26], and with the use of allografts [5,17,22].…”
