Lateral patellotibial ligament reconstruction for medial patellar instability.

ABSTRACT: Medial patellar instability, though infrequently recognized, can be a disabling complication of a lateral retinacular release. Patients with persistent anterior knee pain and instability after lateral release should be evaluated closely. If evidence of increased medial patellar translation is identified on physical examination, a trial of reverse McConnell taping should be prescribed. If there is noted improvement in symptoms after this taping trial, reconstruction of the lateral patellotibial ligament should be considered. This article details our technique for lateral patellotibial ligament reconstruction using iliotibial band and patellar tendon autografts.

Medial Patellofemoral Ligament Reconstruction With Concomitant Lateral Patellofemoral Reconstruction for Patellar Instability.

Project description:Patients with bidirectional patellar instability who are unresponsive to conservative management may benefit from a medial patellofemoral ligament (MPFL) reconstruction and lateral patellofemoral ligament (LPFL) reconstruction. If an isolated MPFL reconstruction does not provide adequate stabilization intraoperatively, combined MPFL and LPFL reconstruction allows independent reconstruction, which can be performed with a facile, reproducible technique. The purpose of this report was to describe our technique for performing an MPFL reconstruction with a concurrent soft-tissue LPFL reconstruction combined with a distalizing tibial tubercle osteotomy to correct patella alta.

Deep Transverse Lateral Retinaculum Reconstruction for Medial Patellar Instability.

Project description:Medial patellar instability can be a disabling complication of an extensive lateral retinaculum release. It is often overlooked, and for the diagnosis, it is necessary to have a high index of suspicion. Typically, the patient feels a new pain and new instability after the lateral retinaculum release that are distinct from, and much worse than, those before surgery. All of our patients had significant relief from their pain with "reverse" McConnell taping. If there is a significant improvement in symptoms after this taping and stress radiographs or stress axial computed tomography scans show an objective pathologic medial patellar displacement, reconstruction of the lateral retinaculum should be considered. This article details our technique for reconstruction of the deep transverse layer of the lateral retinaculum using an anterior strip of the iliotibial band. This strip is detached from its insertion onto the Gerdy tubercle and then reflected proximally beyond the level of the lateral femoral epicondyle. Finally, it is attached either by direct suture to the remaining prepatellar and peripatellar retinaculum if there is adequate tissue present or by a suture anchor.

Simultaneous medial and lateral patellofemoral ligament reconstruction for combined medial and lateral patellar subluxation.

Project description:Medial patellar subluxation (MPS) is a disabling, often iatrogenic patellar instability due to previous lateral release for patellar instability. Lateral release destabilizes the patella on the lateral side, worsening the initial lateral instability and causing MPS. MPS is poorly recognized and may range from subluxation to true dislocation. This report describes a technique developed in response to episodes of medial and lateral patellar subluxation after failed lateral release for patellar instability. The technique uses a graft that extends from the medial patellofemoral ligament origin through the quadriceps tendon to the lateral epicondyle, thereby reconstructing both the medial and lateral patellofemoral ligaments, as well as providing simultaneous stability to both the medial and lateral sides of the patella.

Combined Medial Patellofemoral Ligament, Medial Quadriceps Tendon-Femoral Ligament, and Medial Patellotibial Ligament Reconstruction for Patellar Instability: A Technical Note.

Project description:Lateral patellar dislocations often occur in a young, athletic population of recurrent dislocators with generalized laxity and an interest in returning to an active lifestyle. A recent appreciation for the distal patellotibial complex has directed surgeons toward attempting to re-create the native anatomy and knee biomechanics during medial patellar reconstructive procedures. By reconstructing the medial patellotibial ligament (MPTL) in addition to the medial patella-femoral ligament (MPFL) and medial quadriceps tendon-femoral ligament (MQTFL), the current article describes a potentially more stable construct that can be utilized in patients with subluxation with the knee in full extension, patellar instability with the knee in deep flexion, genu recurvatum, and generalized hyperlaxity. Additionally, the current technique utilizes a tibialis anterior allograft. The purpose of this Technical Note is to describe, in detail, the current authors' technique for a combined MPFL, MQTFL, and MPTL reconstruction.

Combined Medial Patellofemoral Ligament and Medial Patellotibial Ligament Reconstruction for Recurrent Lateral Patellar Dislocation in Flexion.

Project description:Recurrent lateral patellar dislocation can be a challenging entity to manage. It results from an imbalance between the restraints to lateralization of the patella and the forces applied to the patella within the biomechanical environment of the knee. The medial patellofemoral ligament has been recognized as the most important static soft-tissue restraint. However, the medial patellotibial ligament and medial patellomeniscal ligament are important for patellar stability at higher degrees of knee flexion. Lateral patellar dislocation in flexion poses a particularly challenging clinical entity with a combination of unique characteristics that need to be addressed to achieve optimal patellar tracking and stability. In this technical note, we describe a combined medial patellofemoral ligament and medial patellotibial ligament reconstruction technique to address lateral patellar dislocation in flexion.

Sulcus-Deepening Trochleoplasty and Medial Patellofemoral Ligament Reconstruction for Recurrent Patellar Instability.

Project description:There are multiple etiologies for recurrent patellar instability. While patella alta, an elevated tibial tubercle trochlear groove distance, and prior lateral patellar dislocations with medial patellofemoral ligament (MPFL) insufficiency have been shown to be risk factors for recurrent patellar instability, trochlear dysplasia can result in a significant impediment to normal patellar tracking. With the adequate identification of risk factors, appropriate surgical treatments can be individually tailored to the patient. We present a combined surgical technique of a sulcus-deepening trochleoplasty using knotless suture anchors for fixation, with MPFL reconstruction using gracilis autograft through short, oblique patellar bone tunnels to address severe trochlear dysplasia.

Patellofemoral Joint Reconstruction for Patellar Instability: Medial Patellofemoral Ligament Reconstruction, Trochleoplasty, and Tibial Tubercle Osteotomy.

Project description:Recurrent patellar instability can be very debilitating and may require surgical intervention. A thorough workup must be completed in this subset of patients. Risk factors for recurrent instability include patella alta, trochlear dysplasia, an increased tibial tubercle-trochlear groove distance, and insufficiencies in the medial retinacular structures. Necessary treatment of these risk factors, once identified, should be addressed surgically. Patellofemoral reconstruction must be individually tailored to each patient's anatomy and may necessitate medial patellofemoral ligament reconstruction, tibial tubercle osteotomy, or trochleoplasty in any combination or as a standalone procedure. This article details our technique for surgical treatment of recurrent patellar instability with a medial patellofemoral ligament reconstruction, an open trochleoplasty, and a tibial tubercle osteotomy for patients with severe trochlear dysplasia, an increased tibial tubercle-trochlear groove distance, or patella alta.

Trochleoplasty, Medial Patellofemoral Ligament Reconstruction, and Open Lateral Lengthening for Patellar Instability in the Setting of High-Grade Trochlear Dysplasia.

Project description:Trochlear dysplasia is the most commonly encountered pathoanatomy in patients who present with patellar instability. Outcomes of trochleoplasty procedures have shown low rates of recurrent instability and high patient-reported outcome scores. This article describes a "thin-flap" groove-deepening trochleoplasty combined with medial patellofemoral ligament reconstruction with a gracilis allograft and lateral retinacular lengthening to treat recurrent patellar instability due to high-grade trochlear dysplasia. This technique can obviate tibial tubercle osteotomy by normalizing the position of the trochlear groove and, subsequently, decreasing the tibial tubercle-to-trochlear groove distance.

Medial Patellofemoral Ligament Reconstruction With Growth Modulation in Children With Patellar Instability and Genu Valgum.

Project description:Patellar instability is common in the second decade, and genu valgum is a risk factor for patellar instability. In skeletally immature patients, genu valgum can be gradually corrected using less-invasive, well-established, growth-modulation techniques. For skeletally immature patients with patellar instability and genu valgum, it would be desirable to address both instability and deformity. We describe our technique of physeal-respecting medial patellofemoral ligament reconstruction in skeletally immature patients using hamstring autograft and simultaneous transphyseal screw hemiepiphysiodesis to gradually correct genu valgum. The medial patellofemoral ligament reconstruction technique features posteromedial hamstring graft harvest, single patellar tunnel fixation without implant, and femoral attachment just below the distal femoral physis. The technique of growth modulation features percutaneous insertion of a single transphyseal screw through the distal medial femoral physis without interference with medial patellofemoral ligament graft placement. Our preliminary results have been encouraging with successful correction of genu valgum and satisfactory patellar stabilization without growth disturbances.

Medial Closing-Wedge Distal Femoral Osteotomy with Medial Patellofemoral Ligament Imbrication for Genu Valgum with Lateral Patellar Instability.

Project description:A varus-producing distal femoral osteotomy (DFO) is an effective technique for the treatment of lateral patellar instability (LPI) in patients with concomitant moderate to severe valgus malalignment. Patellar maltracking and subluxation are corrected via neutralization of some of the laterally directed forces on the patella due to the valgus deformity. This can be accomplished with a distal femoral lateral opening-wedge or medial closing-wedge osteotomy and medial soft tissue stabilization. A medial closing-wedge osteotomy offers the advantages of immediate weight bearing and a single incision in cases requiring patellofemoral soft tissue stabilization. In this article, we describe our preferred operative technique for a medial closing-wedge DFO using a femoral locking plate and medial patellofemoral ligament imbrication for the correction of LPI.
