Arthroscopic Single-Tunnel Pullout Suture Fixation for Tibial Eminence Avulsion Fracture
Various arthroscopic techniques have been devised for fixation of tibial eminence avulsions, namely percutaneous K-wires, arthroscopy-guided screw fixation, staples, TightRope (Arthrex)–suture button fixation, and transosseous suture fixation. Such techniques provide well-pronounced advantages including less postoperative pain, a reduced hospital stay, and minimal scar with resultant earlier and more compliant rehabilitation. As for transosseous suture fixation, the standard technique comprises the creation of 2 tibial tunnels exiting on both sides of the footprint of the avulsion fracture using an anterior cruciate ligament tibial guide with the angle set at 45°.Arthroscopic Reduction and Fixation of Tibial Spine Avulsion Fractures by a Stainless Steel Wiring Technique
Several techniques of arthroscopic treatment of tibial spine avulsion fractures have been described in the literature. These techniques include the use of various fixation devices such as screws, K-wires, wiring, sutures, and suture anchors. In this study, we evaluate a new wiring technique for the treatment of these injuries. This technique involves fixation by stainless steel tension wires passed over the fractured spine and tied over a bone bridge. The advantages of this technique are that it aids in reduction, allows for compression of the tibial spine fragment anatomically in its fracture bed, provides stable fixation in difficult comminuted fractures, and allows for early mobilization and weight bearing because of the solid fixation.Tibial Eminence Fracture Repair With Double Hewson Suture Passer Technique
Displaced tibial eminence fractures are commonly encountered in pediatric patients and are often considered to be functionally equivalent to an anterior cruciate ligament (ACL) rupture. While a variety of techniques are available for fixation of this injury, we describe an anchorless technique relying on suture fixation tied over a bone bridge. This technique also relies on two intra-articular Hewson suture passers to quickly and effectively pass and shuttle sutures through the ACL and tibial bone tunnels in order to reduce and fix the fracture fragment.Arthroscopic Lysis of Adhesions for Treatment of Post-traumatic Arthrofibrosis of the Knee Joint
Normal knee range of motion varies slightly between individuals and measures approximately 0° to −5° of extension to 140° of flexion. A full arc of motion is required for normal gait and knee function. Loss of normal joint range of motion may occur after a traumatic knee injury and may contribute to increased pain, lower functional outcome scores, and decreased patient satisfaction. Although multiple factors may contribute to the development of motion loss, the occurrence of intra-articular scar tissue adhesions, or post-traumatic arthrofibrosis, may limit the patient's knee motion in the early postoperative period.Arthroscopic Technique for Treatment of Schatzker Type III Tibia Plateau Fractures Without Fluoroscopy
Accurate reduction and maintenance of the stability with correct implant positioning is critical for surgical treatment of tibial plateau fractures. Our technique includes an arthroscopic reduction and fixation of Schatzker type III tibial plateau fractures with a bulls-eye screw placement without fluoroscopy control. With the arthroscopic guidance, an anterior cruciate ligament drill guide is placed and a K-wire sent to the midpoint of the depressed fragment through the guide at a 40° angle to the coronal axis of the tibia.Arthroscopic Reduction of Tibial Spine Avulsion: Suture Lever Reduction Technique
Tibial spine avulsion fractures are uncommon knee injuries that predominantly occur in children and young adults. Restoration of anterior cruciate ligament length through surgical reduction and fixation of the fracture is necessary to ensure stability of the knee with suitable range of motion and minimal knee laxity. Arthroscopic repair of tibial spine avulsion fractures is a technically complex procedure, specifically when performing and maintaining the initial anatomic reduction. We describe in this technical note and accompanying video a unique 3-point fixation repair of tibial spine avulsion fractures using an arthroscopic assisted suture lever reduction technique.A Fluoroscopy-Free Technique for Percutaneous Screw Positioning During Arthroscopic Treatment of Depression Tibial Plateau Fractures
This article aims to describe a simple and reliable technique that helps in positioning the cannulated percutaneous screws during fixation of depression-type tibial plateau fractures. After fracture reduction under arthroscopic control, an outside-in anterior cruciate ligament femoral guide is introduced through the tibial cortical metaphyseal window and positioned under endoscopic control just underneath the elevated fragment. When proper height is achieved, a guide pin is drilled from lateral to medial through the sleeve, 1 to 2 cm distal to the articular surface of the depressed fragment.Arthroscopic Management of a Posterior Femoral Condyle (Hoffa) Fracture: Surgical Technique
Unicondylar fractures of the lower end of the femur are uncommon injuries that usually occur in the sagittal plane. A coronal (tangential) plane fracture, first described by Hoffa in 1904, is unusual. It is an intrinsically unstable type of intra-articular fracture that warrants operative fixation, usually by an open technique. A simple method for the treatment of lateral femoral condyle coronal fractures with arthroscopic-assisted reduction and internal fixation by cannulated screws is reported.Arthroscopic-Assisted Reduction and Percutaneous Fixation of Tibial Plateau Fractures
Tibial plateau fractures present a difficult range of fractures to treat. Arthroscopy allows for a less invasive option when compared with arthrotomy. Furthermore, visualization of the articular surface arthroscopically can allow for a precise reduction and assessment of any concomitant injuries to the articular cartilage and meniscus. By use of arthroscopy, unicondylar lateral plateaus were traditionally approached through a laterally based metaphyseal window. However, in carefully selected patients and fracture patterns, a medially based, arthroscopic-assisted approach can create long bony tunnels for subchondral support and allow for greater ease in fracture reduction.Arthroscopic 4-Point Suture Fixation of Anterior Cruciate Ligament Tibial Avulsion Fractures
Tibial eminence avulsion fractures are rare injuries occurring mainly in adolescents and young adults. When necessary, regardless of patient age, anatomic reduction and stable internal fixation are mandatory for fracture healing and accurate restoration of normal knee biomechanics. Various arthroscopically assisted fixation methods with sutures, anchors, wires, or screws have been described but can be technically demanding, thus elongating operative times. The purpose of this article is to present a technical variation of arthroscopic suture fixation of anterior cruciate ligament avulsion fractures.Arthroscopic Treatment of Acute Tibial Avulsion Fracture of the Posterior Cruciate Ligament Using the TightRope Fixation Device
Avulsion fracture of the posterior cruciate ligament from its tibial insertion is a rare condition. Early surgical treatment has been regarded as necessary, but the optimal surgical technique remains unclear. The purpose of this technical note is to present a novel all-inside arthroscopic reconstruction technique for bony tibial avulsion fractures of the posterior cruciate ligament using the TightRope device (Arthrex, Naples, FL).Arthroscopic Repair of “Peel-Off” Lesion of the Posterior Cruciate Ligament at the Femoral Condyle
Posterior cruciate ligament (PCL) injuries are uncommon, and most occur in association with other lesions. The treatment of PCL injuries remains controversial; in addition, PCL injuries have been documented to have a propensity to heal. In the literature several different patterns of PCL injury have been described including midsubstance tears/injuries, tibial bony avulsions, femoral bony avulsions, and femoral “peel-off” injuries. A peel-off injury is a complete or incomplete soft-tissue disruption of the PCL at its femoral attachment site without associated bony avulsion.Arthroscopic Absorbable Suture Fixation for Tibial Spine Fractures
The purpose of this technical note and accompanying video is to describe a modified arthroscopic suture fixation technique to treat tibial spine avulsion fractures. Twenty-one patients underwent arthroscopic treatment for tibial spine avulsion with our technique; they were clinically and biomechanically evaluated at 2 years' follow-up and showed optimal clinical and radiographic outcomes. Repair with this arthroscopic technique provides a significant advantage in the treatment of type III and IV fractures of the tibial eminence by obtaining arthroscopic fixation within the substance of the anterior cruciate ligament: suture methods based on the avulsed bone fragment are technically impossible, but sutures through the base of the ligament itself provide secure fixation, reducing the risks of comminution of the fracture fragment and eliminating the time for hardware removal.Arthroscopic Preparation and Internal Fixation of an Unstable Osteochondritis Dissecans Lesion of the Knee
We present our arthroscopic technique for fixation of an unstable osteochondritis dissecans (OCD) lesion. This technique includes arthroscopic evaluation of cartilage and bone quality of the OCD fragment, hinging open the lesion, debridement of fibrous nonunion tissue, reducing the fragment, and obtaining multi-point compression screw fixation. This technique avoids the morbidity of an open arthrotomy and should be considered when treating an unstable OCD lesion with adequate bone for fixation.Arthroscopic Treatment of Medial Femoral Condylar Coronal Fractures and Nonunions
Nonunion of medial femoral condylar coronal fractures are uncommon. In neglected Hoffa fractures despite nonunion, there is a risk of missing accompanying ligamentous and intra-articular injuries. Neither preoperative clinical examination nor magnetic resonance imaging showed these injuries before arthroscopy. Arthroscopy before internal fixation gives additional information and changes the surgical protocol for these fractures and nonunions.ORV Arthroscopic Reduction and Internal Fixation of Tibial Eminence Fractures
Tibial eminence fractures are an uncommon but well-described avulsion of the anterior cruciate ligament. Treatment principles are based on the amount and pattern of fracture displacement. Management has evolved from closed reduction and immobilization to arthroscopic reduction and internal fixation followed by early rehabilitation. Various fixation methods have evolved, ranging from arthroscopic reduction and percutaneous screw fixation to arthroscopic suture repair. We present a technique for arthroscopic reduction and internal fixation using a cannulated drill bit and high-strength suture.Arthroscopic Suture Bridge Fixation of Tibial Intercondylar Eminence Fractures
Tibial intercondylar eminence fractures that are displaced and non-reducible require open or arthroscopically assisted repair. Ideally, fracture reduction and fixation would be performed with a technique that has low morbidity, allows easy visualization and reduction, provides firm fixation, does not violate the proximal tibial physis, avoids metal hardware, and does not require a second procedure for implant removal. The suture bridge technique, used in the shoulder for rotator cuff tears and greater tuberosity fracture repair, has the ability to produce high contact pressures with rigid fixation.A Novel Surgical Technique for Patellar Fracture: Application of Extra-articular Arthroscopy With Hanger-Lifting Procedure
We describe a novel operative technique for patellar fracture. The patient is placed in the supine position for setup of both an image intensifier and arthroscopy. After routine intra-articular inspection with an arthroscope, an extra-articular space including the prepatellar bursa is developed. The space is created with a lifting hanger applied from a portal wherein an arthroscope can then afford both intra- and extra-articular observation of the articular and bony surface of the patella. By use of an image intensifier, the fracture can be treated and fixed in percutaneous fashion with the aid of an arthroscope.Treatment of a Lateral Tibial Plateau Osteochondritis Dissecans Lesion With Subchondral Injection of Calcium Phosphate
Osteochondritis dissecans lesions occur frequently in children and adolescents. Treatment can be challenging and depends on the status of the articular cartilage and subchondral bone. Injection of calcium phosphate bone substitute into the area of subchondral bone edema (Subchondroplasty; Knee Creations, West Chester, PA) may be an option. We present a case of a lateral tibial plateau osteochondritis dissecans lesion treated with subchondral injection of nanocrystalline calcium phosphate. Preoperative magnetic resonance imaging is used to determine the area of subchondral edema, and intraoperative fluoroscopy is used to localize this area with the injection cannula.Hybrid Fixation of Tibial Eminence Fractures in Skeletally Immature Patients
Tibial eminence fractures most commonly occur in children and adolescents. When treating displaced fractures of the tibial eminence, some surgeons prefer screw fixation whereas others prefer suture fixation. The ultimate goal is to limit morbidity through early return to range of motion and activity. In this technical note, we describe 2 hybrid fixation techniques for fixing tibial eminence fractures, one for type III and the other for type IV fractures. The first technique (variation A) is used to treat type III fractures and combines use of both a bioabsorbable compression screw and suture for fixation.Arthroscopic Hybrid Fixation of a Tibial Eminence Fracture in Children
The treatment of an anterior cruciate ligament (ACL) avulsion fracture is controversial, especially in skeletally immature patients, because of concerns about physeal damage. To reduce the risk of physeal injury, an arthroscopic technique was performed. A bioabsorbable suture anchor was inserted through anteromedial portals and fixed to a bioabsorbable suture anchor at the center of the fracture bed; it was then passed through the threads at the ACL avulsion fragment and tied with the ACL substance.
