This adds a fair amount of complexity to the procedure. Two-Stage Revision Anterior Cruciate Ligament Reconstruction with Cannulated Allograft Bone Dowels Soaked in Bone Marrow Aspirate Concentrate. Although there are many proposed theories for tunnel lysis, it is most accurate to state that this condition has a multifactorial origin; mechanical and biologic causes have been reported, and both contribute to enlarged graft tunnels [11, 13]. xMO@; aK]XDZ)r(-w(;.B ~8MG{ Recently, a technique for sterilizing musculoskeletal allografts using supercritical carbon dioxide (sCO2) has been developed [26]. 1).

Phys Ther 85:740749, PubMed Graft healing within the bone tunnel after anterior cruciate ligament (ACL) reconstruction is still a complex, poorly understood biological process that is influenced by multiple surgical and postoperative variables. It is technically difficult to deliver and impact bone graft into the femoral tunnel with the standard surgical and arthroscopic instruments. Autogenous grafts are considered the gold standard, due to their osteoinductive, osteoconductive, and osteogenic properties. However, the small number of included patients, especially in the group of patients without revision ACLR, is limited. Additionally, graft-tunnel mismatch is problematic, often leading to inadequate osseous . Am J Sports Med 45:20682076, Erickson BJ, Cvetanovich G, Waliullah K, Khair M, Smith P, Bach B Jr et al (2016) Two-stage revision anterior cruciate ligament reconstruction. Root tears also put tremendous forces on the ACL graft and can lead to rotational instability and graft failure. My surgeon disagrees with me and is firm that the harvest of the bone graft is not separately reportable. Among these potential scenarios requiring a two-stage revision, tunnel-widening is the most common cause; the first stage involves graft removal, tunnel curettage, and bone grafting, followed by revision ACL reconstruction in the second stage. - tunnel positioning: proprioceptive reflex leading to a functional extension loss while the patient is awake.

Part of This site complies with the HONcode standard for trustworthy health information: verify here. % A decision that will often depend on the graft used during the primary ACLR. Finally, 1 study compared ICBG to a synthetic bone substitute. To me it really is a separate issue especially since the debridement was performed first, not as a clean up after the hardware was removed. A patient with a left knee anterior cruciate ligament tear, torn lateral meniscus and retained hardware from a previous anterior cruciate ligament reconstruction presented for a left knee arthroscopic anterior cruciate ligament repair, open removal of retained hardware and bone grafting of the distal femur and tibial tunnels.Following the arthroscopic anterior cruciate ligament repair, a tibial incision was made through subcutaneous tissue to access the tibial tunnel in order to remove the deep hardware. He did other procedures, but I have the codes for them. As this number has continued to increase, the incidence of revision ACL reconstruction (ACLR) has also grown to a rate of between 4.1 and 13.3% of all primary ACLRs performed [2]. This case required a two-stage approach: Stage 1 consisted of bone grafting, followed by second-stage repeat revision ACL reconstruction with patellar tendon autograft, lateral meniscal root repair and iliotibial band tenodesis. Resurfacing technique consisting of transplantation of multiple osteochondral grafts to smooth the area. Two-stage revisions are rarely performed, but are particularly useful when addressing substantial tunnel-widening, active infection, and concomitant knee pathology (e.g., malalignment, other ligamentous injuries, meniscal or chondral lesions).

Improved muscle strength may be the decisive factor; however, changes in functional movement patterns after intensive physical therapy are also important to consider [41]. He founded Orthopaedic Specialists of North Carolina in 2001 and practices at Franklin Regional Medical Center and Duke Raleigh Hospital. When performing a revision reconstruction, the surgeon decides between a single-stage or a two-stage revision. Similarly, root tears of the lateral meniscus are often missed as well. $.' Louis et al.

They explained that because a bone tunnel of 15mm diameter with 45 of inclination resulted in a tibial tunnel aperture of >20mm, a 20-mm tunnel aperture was regarded as a candidate for grafting. 2022 Feb 28;11(3):e463-e469. But an iliac-crest autograft is comparatively invasive with relatively high donor-site morbidity and the potential for insufficient yield quantities [11, 22]. Dr. Wheeless enjoys and performs all types of orthopaedic surgery but is renowned for his expertise in total joint arthroplasty (Hip and Knee replacement) as well as complex joint infections.

Autograft was used in 4 studies: iliac crest bone autograft (ICBG, n = 3) and tibial bone autograft (TBA, n = 1). Revision ACLR surgeries can be mainly divided into one-stage and two-stage procedures. Epub 2016 Dec 30. This will allow the desired placement of the new tunnels without the risk of loss of structural integrity. PubMedGoogle Scholar. The patients were divided into two groups based on the tunnel diameter (group A, <12mm; group B, <12mm).

I just want to get the basic idea so I can advise him since he keeps a copy of his billing. #1. The greater the tibial slope, the higher the risk of graft failure as our group found in a 2015 study in American Journal of Sports Medicine. Conclusion: <> Careers. endobj We thank Eun-Ji Jeon and Min-Ji Kim for their support. The insertion of an interference screw not only compresses the graft in the tunnel but also leads to an enlargement of the bone tunnel itself [13]. Hi you mentioned this was a staged procedure - any chance you can post the entire operative report without patient info? Hybrid Bone-Grafting Technique for Staged Revision Anterior Cruciate Ligament Reconstruction. There are numerous challenges to revision ACL surgery with regard to graft selection, timing of surgery, and whether or not the surgery can be performed in a single operation or multiple-staged surgeries.

The initial rehabilitation emphasis is focused on restoring tibiofemoral and patellofemoral passive range of motion, restoring quadriceps activation, and controlling and resolving any joint effusion. In cases like these your going to need to bill out "what you can" which in this case would be 20680. They recommended that two-stage reconstruction could be safely performed at 24weeks after bone grafting by the iliac-bone block-grafting technique.
