Surgical Management of Proximal Tibiofibular Joint Instability Using an Adjustable Loop, Cortical Fixation Device.

ABSTRACT: A technique for proximal tibiofibular joint stabilization using an adjustable loop, cortical fixation device is presented. A standard diagnostic arthroscopy is performed to exclude intra-articular pathology. After arthroscopy, a 5-cm posterior-based curvilinear incision is made over the fibular head with dissection of the fascia and decompression of the common peroneal nerve ensuring adequate exposure of the fibular head. A guidewire is placed across 4 cortices using fluoroscopic guidance from the fibular head to the anteromedial tibia. A cannulated drill bit is guided through the 4 cortices. A shuttle wire carrying the adjustable loop, cortical fixation device is fed from lateral to medial and through the skin until the medial cortical button is deployed. The device is tightened until the lateral circular cortical button is secured on the fibula. Fluoroscopy is performed to confirm the button position. The device is secured after tensioning by tying the sutures. To confirm joint stabilization, a shuck test can be performed. If a second fixation device is necessary, this procedure can be repeated distally to the first.

Cortical Button Fixation for Proximal Tibiofibular Instability: A Technical Report.

Project description:Instability of the proximal tibiofibular joint (PTFJ) is a rare injury pattern than can affect high-demand athletes involved in twisting or pivoting movements on a flexed knee. Instability may produce painful subluxations during provocative activity and occasional neuritic symptoms from tethering of the common peroneal nerve at the fibular neck. There are several reports of reconstruction for symptomatic PTFJ instability; however, no optimal treatment has been elucidated in the literature. Use of a cortical button suspensory device for fixation of the PTFJ offers the advantage of stabilizing the joint without need for free graft harvest or rigid screw fixation. The present technical report illustrates the operative technique and the advantages, disadvantages, pearls, and pitfalls associated with this operation.

Treatment of Instability of the Proximal Tibiofibular Joint by Dynamic Internal Fixation With a Suture Button.

Project description:Injury to the proximal tibiofibular joint can lead to lateral knee pain and instability owing to chronic rupture of the posterior tibiofibular ligament. The condition is often missed, and the true incidence is unknown. A variety of surgical treatments have been proposed over the last decades. Methods such as arthrodesis and fibular head resection have largely been replaced with various reconstruction techniques using autografts. The purpose of this report is to describe our method for treatment of proximal tibiofibular joint instability by dynamic internal fixation with a suture button.

Instability of the proximal tibiofibular joint associated with total knee arthroplasty.

Project description:To our knowledge, proximal tibiofibular joint instability has never been reported in a patient with a total knee arthroplasty (TKA). We present the case of a patient with anterolateral proximal tibiofibular joint instability associated with a complex primary TKA. In 2010, a male patient of 47 years was referred for TKA after posttraumatic osteoarthritis. The patient's history includes a fracture of the left lateral tibial plateau in 2008 and removal of osteosynthesis material in 2009. TKA with a lateral metal augment and intramedullary stem was performed in 2010. After TKA, instability of the left proximal tibiofibular joint (PTFJ) was diagnosed. The patient underwent PTFJ arthrodesis and, at 5 years' follow-up, had no residual pain, with full range of motion. In this case, arthrodesis was the only possible surgical option because reconstruction surgeries require the establishment of bone tunnels in the tibia and fibula for the passage of a graft. Low bone quality and the use of an intramedullary stem with a metal augment in the tibia made any reconstruction technique unfeasible because the proximal tibia was obliterated. Although several PTFJ reconstruction techniques are available, they are difficult to apply to patients with a complex TKA.

Arthroscopic Iliac Crest Bone Block for Reconstruction of the Glenoid: A Fixation Technique Using an Adjustable-Length Loop Cortical Suspensory Fixation Device.

Project description:Recurrent anterior shoulder instability with significant bone loss represents a surgical challenge. Anterior bone block procedures including variations of the Latarjet coracoid transfer have been used in this setting. Bone graft resorption with prominence of the metalwork is a serious concern, whereas the relative contribution of the dynamic sling effect of a Latarjet procedure is still controversial. We describe an arthroscopic technique for anatomic reconstruction of anterior glenoid bone defects using autologous iliac crest graft. This technique allows accurate placement of the bone block; fixation with 2 knotless TightRope devices (Arthrex, Naples, FL), avoiding the use of screws; and a final labral repair.

Anatomic Reconstruction of the Proximal Tibiofibular Joint.

Project description:Proximal tibiofibular joint (PTFJ) instability can be easily missed or confused for other, more common lateral knee pathologies such as meniscal tears, fibular collateral ligament injury, biceps femoris pathology, or iliotibial band syndrome. Because of this confusion, some authors believe that PTFJ instability is more common than initially appreciated. Patients with PTFJ subluxation may have no history of inciting trauma or injury, and it is not uncommon for these patients to have bilateral symptoms and generalized ligamentous laxity. Currently, the optimal surgical treatment for patients with chronic PTFJ instability is unknown. Historically, a variety of surgical treatments have been reported. Initially, joint arthrodesis and fibular head resection were recommended. More recently, temporary screw fixation, nonanatomic reconstruction with strips of the biceps femoris tendon or iliotibial band, and reconstruction with free hamstring autograft have been described. The purpose of this report is to present our surgical technique for treatment of chronic PTFJ instability using an anatomic reconstruction of the posterior ligamentous structures of the PTFJ with a semitendinosus autograft.

Anatomic Posterolateral Corner Reconstruction Using Single Graft Plus Adjustable-Loop Suspensory Fixation Device.

Project description:The original description of the LaPrade technique for anatomic posterolateral corner reconstruction addresses the 3 main stabilizing structures: the fibular collateral ligament, the popliteus, and the popliteofibular ligament. The use of two separate grafts (originally described with a tendo-Achilles allograft) may restrict the utility of the technique when sources of allograft may be limited and autografts must be used, particularly in the context of multiligament reconstruction. We present a modification of the technique, in which an adjustable cortical button is used for tibial fixation, which allows for the use of a single graft while maintaining the ability to independently tension the popliteus, popliteofibular ligament, and fibular collateral ligament limbs of the graft.

Revision Proximal Tibiofibular Joint Reconstruction for the Treatment of Chronic Instability Secondary to Suture Button Construct Failure.

Project description:Recurrent proximal tibiofibular joint (PTFJ) instability can result from nonanatomic repair using a suture button construct. During initial reconstruction, proper identification of anatomic landmarks is critical for proper placement of suture button construct components and successful patient outcomes. In cases of symptomatic recurrent instability, a PTFJ reconstruction revision is warranted to alleviate symptoms of pain and instability. This Technical Note describes a technique for performing an anatomic PTFJ reconstruction revision and fibular collateral ligament reconstruction in which the semitendinosus is used as a graft for both the FCL and posterior ligamentous complex of the PTFJ. The biceps femoris is also repaired following a tear that resulted from a misplaced suture button.

Minimally Invasive Combined Anterior and Anterolateral Stabilization of the Knee Using Hamstring Tendons and Adjustable-Loop Suspensory Fixation Device: Surgical Technique.

Project description:Despite the numerous techniques described regarding isolated anterior cruciate ligament (ACL) reconstruction, many authors have reported that residual knee rotational instability is not always eliminated. The combination of lateral extra-articular knee tenodesis and ACL reconstruction is an alternative surgical approach with very promising clinical results. The purpose of this article is to describe a reliable and reproducible technique of combined ACL reconstruction and lateral extra-articular knee tenodesis using a continuous looped hamstring tendon autograft. A 4-strand graft inside the joint and a 2-strand graft for the tenodesis are attached to 2 adjustable-loop button suspensory fixation devices.

Graft Retensioning Technique Using an Adjustable-Loop Fixation Device in Arthroscopic Anterior Cruciate Ligament Reconstruction.

Project description:Anterior cruciate ligament (ACL) tears are an unfortunate and devastating injury in the athletic patient. Surgical reconstruction of the ACL with a taut graft construct is necessary to restore knee stability and help expedite the patient's return to an active lifestyle. Arthroscopy-assisted ACL reconstruction can be a technically involved procedure, where strong fixation limits graft motion to allow sufficient healing within the tibial and femoral tunnels at the bone-tendon interfaces. Loss of tension in a graft can cause symptomatic anterior or rotatory instability and potential retear of the ACL graft. We describe in this Technical Note and accompanying video a simple and effective technique to implant and retension a tendon graft during ACL reconstruction using a suspensory fixation device. The technical description uses a simple adjustable-loop device to provide strong cortical fixation, along with the unique ability to retension the graft in ACL reconstruction, not otherwise possible with previously described graft fixation techniques.
