Surgical Technique: Anatomic Medial Patellofemoral Ligament Retensioning Repair.

ABSTRACT: The medial patellofemoral ligament (MPFL) and the MPFL/vastus medialis obliquus complex are essential for patellar stability. Insufficiency of the MPFL can lead to altered biomechanics and patellofemoral joint contact pressure, high recurrence rate, osteochondral lesions, compromised knee function, and patellofemoral osteoarthritis. Most frequently surgical reconstruction of the MPFL is performed to address patellar instability; however, open physis and donor site morbidity can be a concern. This Technical Note presents a surgical technique to identify the insufficient MPFL and describes in detail an anatomical retensioning repair of the MPFL to restore patellar stability.

Tibial Tuberosity Transfer in Combination With Medial Patellofemoral Ligament Reconstruction: Surgical Technique.

Project description:The stability of the patellofemoral joint relies on the tenuous interplay of soft tissue and bony factors. Anatomic risk factors for instability include a shallow trochlea, an abnormally lateral tibial tubercle position, patella alta, hypermobility, or a secondary injury to the medial patellofemoral ligament (MPFL). There is an increasing interest in restoring normal anatomy to achieve stability, and at times more than 1 abnormality exists. This article describes the technique for combining a tibial tuberosity transfer and an MPFL reconstruction. The key features include planning of skin incisions to enable both operations to be undertaken, planning of the screw placement before osteotomy is performed and assessment of the joint through a superolateral portal to assess the need for MPFL reconstruction after tuberosity transfer.

Patella Footprint Technique-A Surgical Method for Medial Patellofemoral Ligament Reconstruction.

Project description:Recurrent patella instability is a common condition that may potentiate substantial knee dysfunction resulting in loss of time from work and sports. There are numerous factors that contribute to recurrent patella instability including tearing of the medial patellofemoral ligament (MPFL), shallow trochlea, valgus alignment, externally rotated tibia tubercle, ligamentous laxity, elevated Q angle, and increased tibial tuberosity trochlear groove distance. Reconstruction of the MPFL has been shown to restore patella stability where concomitant pathology is within acceptable limits. Major complications include recurrence from inadequate MPFL reconstruction or failure to address other pathology, patella femoral pain from over constrained MPFL or unaddressed cartilage defects to the patella femoral compartment, or patella fracture. This technique provides a reproducible method of restoring patella stability through MPFL reconstruction while minimizing stress risers in the patella by using suture anchor fixation that creates a ligamentous footprint instead of tendon healing into a socket on the patella.

"The Superficial Quad Technique" for Medial Patellofemoral Ligament Reconstruction: The Surgical Video Technique.

Project description:With the introduction of the superficial quad technique, there has been a recent revival of interest in the quadriceps tendon as a graft choice for medial patellofemoral ligament (MPFL) reconstruction. The superficial quad technique has many anatomic advantages because the length, breadth, and thickness of the graft are similar to those of the native MPFL; moreover, the graft provides a continuous patellar attachment at the superior half of the medial border of the patella. The technique requires neither a patellar bony procedure nor patellar hardware. Biomechanically, the mean strength and stiffness of the graft are very similar to those of the native MPFL. The anatomic and biomechanical advantages depend on correct identification of the anatomic superficial lamina of the quadriceps tendon; hence the correct harvesting technique for the superficial lamina is crucial. Various sub-techniques for harvesting the quadriceps graft have emerged recently, such as superficial strip, pedicled, or partial graft harvesting; these can create confusion for surgeons. Additional confusion related to the preparation and fixation of the graft should also be addressed to avoid any potential complications. A step-by-step video of the superficial quad technique is presented, covering the exact dissection of the graft material and its preparation, delivery, and fixation.

Basket-Weave Technique for Medial Patellofemoral Ligament Reconstruction.

Project description:The anatomy of the medial patellofemoral ligament (MPFL) has been well defined, with parts of its uppermost fibers having a soft-tissue insertion onto the vastus intermedius. Bone tunnels and implants on the patellar side therefore cannot replicate this anatomic construct precisely. Because of implants and tunnels, complications have been reported with bone tunnel fracture. Similarly, on the femoral side, rigid fixation with implants can result in over-constraint with compromised results. Moreover, bone tunnels cannot be used in skeletally immature cases. To overcome issues related to bone tunneling and implants, as well as to reconstruct the MPFL in a precise anatomic manner, an all-soft-tissue fixation technique was devised. Bony landmarks were used as reference points instead of radiologic markers to achieve a more precise construct and to eliminate intraoperative radiography. Hamstring graft was used to reconstruct the MPFL. Special suturing techniques were used to achieve optimal graft fixation with minimal suture knots. A special tissue elevator-suture passer device was designed to facilitate graft passage and ease in performing the procedure. This technique permits differential tensioning, and therefore one achieves stability throughout the range of motion.

Medial Patellofemoral Ligament Reconstruction Using Dual Patella Docking Technique.

Project description:Medial patellofemoral ligament (MPFL) injuries are common in children and young adults. In patients with recurrent patellar dislocations with normal lower-extremity alignment, anatomic reconstruction of the MPFL has been shown to restore patellar stability. We describe a technique that creates an anatomic reconstruction using a dual docking technique into the patella. Our technique is simple and efficacious for reconstructing the MPFL without implant fixation in the patella, allowing a maximal bone-tendon interface for healing.

Medial Patellofemoral Ligament Repair With Suture Tape Augmentation.

Project description:The medial patellofemoral ligament (MPFL) is the main restraining force in the first 20° of flexion against lateral patellar displacement and is disrupted after patellar subluxation or dislocation. MPFL reconstruction is frequently performed when conservative management fails and the patient has recurrent patellar dislocations. However, a variety of complications have been reported in the literature with this procedure. Internal bracing with suture tape augmentation encourages healing and allows early mobilization. This article describes, with video illustration, MPFL repair with suture tape augmentation.

Medial patellofemoral ligament reconstruction using a modified "reverse-loop" technique.

Project description:Medial patellofemoral ligament reconstruction is a commonly performed procedure for patellofemoral instability. In recent years the surgery has evolved considerably as the anatomy and goals of reconstruction have become more defined. This has resulted in numerous surgical options involving various fixation devices. Furthermore, as biomechanical data accumulate regarding the importance of graft position and tension, surgical techniques for applying this knowledge with precision are needed. This technical note with an accompanying video details one such technique that may be applied to various methods of fixation, allowing for improved precision and possibly resulting in a stronger fixation construct.

Suture Tape Augmentation Repair of the Medial Patellofemoral Ligament.

Project description:Adolescents with osteochondral loose bodies after a first-time patellar dislocation are most commonly treated with surgical intervention. However, the ideal method of managing a concurrent medial patellofemoral ligament (MPFL) disruption is still unknown. Recent evidence suggests high failure rates are associated with primary MPFL repair. The purpose of this Technical Note is to describe an alternative surgical technique for managing acute first-time patellar dislocations by using high-strength suture augmentation of the MPFL.

Medial Patellofemoral Ligament Reconstruction Using a Femoral Loop Button Fixation Technique.

Project description:Medial patellofemoral ligament (MPFL) reconstruction is a common procedure used to treat both acute and chronic patellar instability. Although many variations of MPFL reconstruction have been described, there is no consensus regarding the optimal surgical technique. We describe a technique for MPFL reconstruction with a looped gracilis tendon autograft using suture anchors to secure the graft to the patella and a suspensory loop button system for fixation to the femur. This technique replicates the native shape of the MPFL while minimizing the risk of patellar fracture and allowing for gradual tensioning of the graft.

Anatomic reconstruction of the medial patellofemoral ligament using the fascia lata as an autograft.

Project description:The medial patellofemoral ligament (MPFL) ensures stability of the patella against lateral forces. In cases of recurrent lateral patellar luxation, surgical reconstruction of the MPFL has an important role in treating lateral patellar instability. Several biomechanical studies have presented valuable pieces of information about various techniques for re-creating this medial patellofemoral complex mainly using the gracilis tendon as an autograft. However, with the increasing number of MPFL reconstructions, there are also an increasing number of patients requiring revision MPFL reconstruction. Therefore alternative graft options may become more relevant. Furthermore, the gracilis tendon as a tubular graft may not be able to fully restore patellofemoral kinematics compared with the native MPFL. This article introduces a surgical technique using the fascia lata as an alternative graft option for the anatomic reconstruction of the MPFL.
