They observed that revision ACLR in combination with ALL reconstruction significantly reduced rotational laxity and showed a higher rate of return to the same level of sports activity than revision ACLR alone, although there were no significant differences in anterior laxity or functional test results between the two groups. A Comparison of 2 Drilling Techniques on the Femoral Tunnel for Anterior Cruciate Ligament Reconstruction. If any of those ligaments were missed in the initial knee surgery, they can be treated in the revision setting. - this restricts flexion of knee if graft remains intact, or it may elongate graft if the range of motion is restored; But an iliac-crest autograft is comparatively invasive with relatively high donor-site morbidity and the potential for insufficient yield quantities [11, 22]. For a better experience, please enable JavaScript in your browser before proceeding. Typically, a staged procedure requires an average delay of 4 to 6months to allow for the bone defect to heal [11, 18], likely subjecting patients to a prolonged period of knee instability and thus adding to the risk of meniscal injury, additional deterioration of muscle strength, and osteochondrosis [32]. In theory, the sCO2-sterilized graft only provides osteoconductive properties to the grafted bone tunnels.

At a mean follow-up of 6years, the laxity measurements achieved with a two-stage revision ACLR can be similar to those achieved after primary ACLR, although the IKDC rating is lower. In addition, patients who receive revision ACL surgery might have other damaged ligaments. Abstract The . The goal of revision ACLR is to improve knee stability and activity levels, but the outcomes are reported to be inferior to those of primary ACLR [3].

Therefore, the coronal and sagittal images (four-tunnel view; femur-coronal, tibia-coronal, femur-sagittal, tibia-sagittal) are primarily used (Fig. Can anatomic femoral tunnel placement be achieved using a transtibial technique for hamstring anterior cruciate ligament reconstruction? Tunnel widening is generally cavitary, frequently maximal in the mid-zone of the tibial tunnel. 8600 Rockville Pike 2021 Oct 12;11(4):e20.00055. The use of allograft material negates the issue of donor-site morbidity but carries the potential risk of disease or infection transmission [23, 24]. At a mean follow-up 6.7years postoperatively, 66.7% of patients had returned to their preoperative sports activity level, 23.3% had changed to lower, non-impact sports, and 10% had given up any sports activity. <> All rights reserved. femoral tunnel too far anterior in the notch; However, an absolute threshold for how much tunnel-widening and bone loss is acceptable to undergo a single stage with an intraoperative bone graft prior to drilling has not been established [4, 16,17,18,19].

Autogenous grafts are considered the gold standard, due to their osteoinductive, osteoconductive, and osteogenic properties. 19 Despite favorable outcomes after interference screw fixation, there are concerns related to graft biology, such as graft damage during screw insertion, a small tendon-to-bone contact area for graft integration, the presence of . In 2-stage revisions, bone grafting of the tunnels may be undertaken if the primary position was inaccurate or if osteolysis has caused widening of the tunnels. Clin Sports Med 28:203214 vii, Islam A, Chapin K, Moore E, Ford J, Rimnac C, Akkus O (2016) Gamma radiation sterilization reduces the high-cycle fatigue life of allograft bone. In 4 studies, the authors reported the time interval between first and second surgeries, with an average of 6.1 months for ICBG compared with 8.7 months for allogenic and synthetic grafts. If no autograft is available for revision surgery, they advise augmentation of the allograft with the lateral extra-articular iliotibial band procedure to reduce the high failure rate associated with the use of the allograft. He is only grafting the bone. Patients who have lost a meniscus or have a significant cartilage defect and have a failed ACL can, in some circumstances, require a meniscus transplant or cartilage replacement surgery. Federal government websites often end in .gov or .mil. This is the great debate in ortho coding. Approximately 200,000 anterior cruciate ligament (ACL) ruptures occur in the United States annually. Patient age and activity level are also important factors when deciding on graft choice for revision procedures.

Data Trace is the publisher of In addition, we obtain single leg knee-to-ankle lateral X-rays to assess for any sagittal plane malalignment as well as to look for excessive tibial slope. Orthop Clin North Am. American Journal of Sports Medicine. Disclaimer. This study aims to identify potential factors for both femoral and tibial tunnel widening (TW) and to investigate the effect of TW on postoperative outcomes after anterior cruciate ligament (ACL) reconstruction with a tibialis anterior allograft. There are several procedures that can be performed in the ACL revision setting, such as anterolateral ligament reconstruction and iliotibial band tenodesis, to control that rotation. 2007 May;23(5):558.e1-4. 2020 Dec 21;9(12):e1917-e1925.

[31] used Si-CaP for a bone-graft substitute for tunnel augmentation in two-stage revision ACLR. Two-stage revision ACLR typically involves an initial bone-graft procedureto fill the widened or misplaced tunnelsand subsequent time to allow for the bone graft to heal sufficiently before the second stage is undertaken [ 5 ]. Preoperative planning is critical to identify and characterize bone tunnel pathology. I am still awaiting the OP note from the ASC, which takes weeks, so I can't post it.

Evaluations were performed in the axial plane of the tibia using three parameters (occupying ratio, union ratio, and bone mineral density). Major reasons to proceed with a two-stage strategy include tunnel-widening or other loss of bone stock, tunnel malposition, arthrofibrosis, active infection, concomitant meniscal deficiency, malalignment, and focal chondral lesions and/or other ligamentous laxity that may require a staged approach [8, 9] (Table1). Autograft bone, either from the iliac crest or anterior tibial plateau, is still considered the gold standard source for grafting because of its osteoconductive, osteoinductive, and osteogenic properties.
