At Mayo Clinic, we have the imaging, surgical and physical therapy teams to manage extremely complex knee issues. Autograft was used in 4 studies: iliac crest bone autograft (ICBG, n = 3) and tibial bone autograft (TBA, n = 1). 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. HHS Vulnerability Disclosure, Help A revision procedure may be performed to improved knee function, correct instability, and facilitate a return to normal activities. MeSH - Surgical Technique: This site needs JavaScript to work properly. Unfortunately, both previous reconstructions were performed with allograft (cadaver) tissue, which has been shown to have significantly higher failure rates in young patients compared with autograft (the patient's own tissue). Two years after the surgery, she resumed all activities and plays collegiate volleyball. Although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. The two-stage group contained significantly more patients with meniscal and chondral pathology compared with the primary ACLR group. American Journal of Sports Medicine. To compare the outcomes of different bone graft materials for staged revision ACL reconstruction. The indication for bone grafting and between-stage protocol varied among studies. Successful revision surgery requires an understanding of the cause of failure, careful preoperative planning, meticulous surgical execution, proper postoperative rehabilitation, and appropriate patient counseling [4]. Si-CaP appears to provide a more stable osteoconductive scaffold to support faster angiogenesis. Accessibility 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.

American Journal of Sports Medicine. Bone tunnel-related issues are frequently encountered during revision anterior cruciate ligament reconstruction. A lot of factors help us to determine whether a single revision or a two- or multiple-stage revision would be best for a particular patient. [11] reported the results of 49 consecutive two-stage revision ACLRs in which the tibial tunnel was grafted (the bone graft was taken from the ipsilateral iliac crest) during the first stage, followed by an ACLR using various grafts and fixation methods for the second stage. A systematic review using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed. I would look at billing 29877 for the debridement of the soft tissue.

Varus or valgus malalignment can put strain on an ACL graft, whatever the malalignment's cause the patient's physiology, failed meniscal surgery or cartilage problems. Improved muscle strength may be the decisive factor; however, changes in functional movement patterns after intensive physical therapy are also important to consider [41].
