Anterior Closing Wedge Proximal Tibial Osteotomy for Slope Correction in Failed ACL Reconstructions.

ABSTRACT: Increased sagittal plane posterior tibial slope has been identified as a risk factor for primary anterior cruciate ligament reconstruction (ACLR) failure. Although ACLR failure is multifactorial, correction of sagittal plane posterior tibial slope should be evaluated in patients with an ACLR graft rupture. There are limited technical descriptions of proposed decreasing tibial slope osteotomy procedures; therefore, the purpose of this Technical Note is to describe the current senior author's technique of performing an anterior closing wedge proximal tibial osteotomy to decrease sagittal plane tibial slope in patients requiring a revision ACLR.

Tibial Tubercle Preserving Anterior Closing Wedge Proximal Tibial Osteotomy and ACL Tunnel Bone Grafting for Increased Posterior Tibial Slope in Failed ACL Reconstructions.

Project description:Anterior cruciate ligament reconstruction (ACLR) failure is multifactorial, but it is known that increased posterior tibial slope (PTS) leads to a greater likelihood of ACLR failure. This technical note describes the senior author's technique for performing an anterior closing wedge proximal tibial osteotomy, in which the osteotomy is made proximal to the tibial tubercle. This procedure is the first part of a staged surgery for patients with multiple failed ACLRs and increased sagittal plane PTS. Debridement of osteolytic reconstruction tunnels with bone grafting is also undertaken in preparation for a second-stage revision ACLR.

Anterior Closing-Wedge Osteotomy for Posterior Slope Correction With Tibial Tubercle Preservation.

Project description:An excessive posterior tibial slope has been identified as a potential risk factor for anterior cruciate ligament tears. Anterior closing-wedge osteotomy decreases the posterior slope and can eliminate this risk factor in patients with recurrent instability and greater than 12° posterior slope. We will describe an anterior closing-wedge osteotomy technique performed at the tibial tubercle (TT), in which the TT is not detached to preserve the extensor mechanism attachment. A vertical cut is performed in the sagittal plane just posterior to the TT, leaving a distal cortical hinge. Two proximal parallel K-wires and 2 distal parallel K-wires convergent to the proximal ones are inserted from the anterior cortex on both sides of the tubercle toward the tibial posterior cortex at the posterior cruciate ligament's tibial insertion. Proximal and distal cuts are performed to remove the bone wedge. Reduction is achieved by gentle knee extension. Fixation is completed with 2 staples placed medially and laterally to the TT.

Anterior Closing-Wedge Osteotomy for Posterior Slope Correction.

Project description:Increased tibial slope can be a cause of recurrent instability after anterior cruciate ligament reconstruction. This article presents a technique for an anterior closing-wedge osteotomy for slope correction. The indications for this procedure are patients with recurrent instability after anterior cruciate ligament reconstruction with a neutral leg axis or slightly varus deformity and a posterior slope of more than 12°. The exposure of the anterior aspect of the tibia is best made through an anterior approach approximately 1 to 2 cm medial to the tibial tuberosity. Hohmann retractors are placed from the medial and lateral sides behind the proximal tibia. The osteotomy lines are marked with 2 converging Kirschner wires with the use of an image intensifier. The entry point of the first Kirschner wire is just below the most inferior fibers of the patellar tendon. The hinge of the osteotomy should be just below the tibial insertion of the posterior cruciate ligament. The osteotomy is performed with an oscillating saw. The posterior cortex of the tibia should be left intact. After removal of the anterior base wedge, the osteotomy is closed by manual pressure. Osteosynthesis is performed with a lag screw from the tibial tuberosity to the distal tibia and an angular stable plate fixator.

Posteromedial Opening-Wedge Tibial Osteotomy for Metaphyseal Varus and Abnormal Posterior Slope Correction in Failed Anterior Cruciate Ligament Reconstructions Using a Custom Cutting Guide.

Project description:Anterior cruciate ligament reconstruction after graft failure may need associated bone correction to ensure stability of the knee. This article presents a technique of posteromedial opening-wedge osteotomy using a custom cutting guide to correct increased tibial slope and metaphyseal varus deformity after recurrent graft failure. An autograft quadriceps tendon graft was selected for the revision anterior cruciate ligament graft. After exposure with an anteromedial incision a patient specific cutting guide was used to make the high tibial osteotomy. The final fixation of the posteromedial opening was achieved using a low-profile locking plate and a femoral head allograft bone wedge. The tibial tunnel was planned and included in the patient-specific cutting guide. The femoral tunnel was placed using an outside to in manner. Bioabsorbable screws were used as fixation devices.

Medial Closing-Wedge Distal Femoral Osteotomy: Fixation With Proximal Tibial Locking Plate.

Project description:Distal femoral varus osteotomy is a well-established procedure for the treatment of lateral compartment cartilage lesions and degenerative disease, correcting limb alignment and decreasing the progression of the pathology. Surgical techniques can be performed with a lateral opening-wedge or medial closing-wedge correction of the deformity. Fixation methods for lateral opening-wedge osteotomies are widely available, and there are various types of implants that can be used for fixation. However, there are currently only a few options of implants for fixation of a medial closing-wedge osteotomy on the market. This report describes a medial, supracondylar, V-shaped, closing-wedge distal femoral osteotomy using a locked anterolateral proximal tibial locking plate that fits anatomically to the medial side of the distal femur. This is a great option as a stable implant for a medial closing-wedge distal femoral osteotomy.

Proximal Tibial Opening Wedge Osteotomy for the Treatment of Posterior Knee Instability and Genu Recurvatum Secondary to Increased Anterior Tibial Slope.

Project description:Decreased posterior tibial slope has been associated with increased risk of graft failure and knee instability after posterior cruciate ligament (PCL) reconstruction. Premature physeal arrest at the tibial tubercle is a common cause of osseous genu recurvatum. Surgical management is recommended to correct the tibial slope and prolong the integrity of the PCL graft. This article discusses our preferred treatment using a proximal tibial opening wedge osteotomy for surgical management of posterior knee instability and genu recurvatum secondary to significant anterior tibial slope.

Opening-Wedge Proximal Tibial Osteotomy.

Project description:Varus knee malalignment caused by medial compartment arthritis results in progressive asymmetric wear of the tibiofemoral joint. This wear can cause progressively painful gonarthrosis. Surgical methods to address varus knee malalignment include lateral closing-wedge proximal tibial osteotomy, medial opening-wedge osteotomy, and arthroplasty. Medial opening-wedge proximal tibial osteotomy is an effective procedure for restoring proper coronal alignment and reducing knee pain. In this technical note, we present a reproducible technique for proximal tibial osteotomy.

Medial Opening Wedge Proximal Tibial Osteotomy.

Project description:Genu varus malalignment can lead to medial compartment overload and progression of ipsilateral compartment osteoarthritis. To slow this process, a medial opening wedge proximal tibial osteotomy (PTO) can be performed. This type of PTO is indicated in patients with genu varus malalignment and isolated medial compartment osteoarthritis of the knee, prior to or concurrent with medial compartment cartilage procedures or meniscal transplants, chronic posterolateral corner deficiency, or chronic anterior cruciate ligament deficiency. When treating ligamentous instability, a PTO can be performed in isolation, with simultaneous ligament reconstruction, or as a staged procedure with the osteotomy first, followed by ligament reconstruction if instability persists. Failure to address malalignment in cases of concurrent ligament reconstruction leads to increased stress on the graft and potential graft failure. One distinct advantage of this procedure is the ability to correct deformities in the sagittal and coronal planes. The purpose of this article was to describe our technique used to perform a medial opening wedge PTO.

Anterolateral Biplanar Proximal Tibial Opening-Wedge Osteotomy.

Project description:Proximal tibial anterolateral opening-wedge osteotomies have been reported to achieve successful biplanar lower-extremity realignment. Indications for a proximal tibial anterolateral osteotomy include symptomatic genu recurvatum with genu valgus alignment, usually in patients with a flat sagittal-plane tibial slope. The biplanar approach is able to simultaneously address both components of a patient's malalignment with a single procedure. The correction amount is verified with spacers and intraoperative imaging, while correction of the patient's heel height is simultaneously measured. A plate is secured into the osteotomy site, and the site is filled with bone allograft. The anterolateral tibial osteotomy has been reported to be an effective surgical procedure for correcting concomitant genu recurvatum and genu valgus malalignment.

Anterior Proximal-to-Posterior Distal Oblique Proximal Tibial Osteotomy.

Project description:High tibial osteotomy is a common procedure to address unicompartment knee osteoarthritis and other conditions. Regarding the specific surgical methods, medial open wedge osteotomy and lateral close wedge osteotomy are the most used. Both methods have a common disadvantage in that they are not so suitable to correct a severe deformity. Thus, we would like to introduce an anterior proximal-to-posterior distal oblique proximal tibial osteotomy technique, which is especially suitable to correct severe tibial deformity. The most critical point of this technique is to create an osteotomy plane from the most proximal posterior site of the tibial tubercle posteriorly and distally to the posterior cortex of the tibia, with each horizontal osteotomy maneuver in the coronal plane. Combined fibular osteotomy is always needed, and better results can be obtained when it is combined with arthroscopic debridement of the knee. We consider the introduction of this technique will provide a useful option when tibial osteotomy is needed to preserve the knee, especially for a great deformity correction.
