Stabilizing the acromioclavicular joint in the vertical and horizontal planes is challenging, and most current techniques do not reliably achieve this goal. The BiPOD repair is an arthroscopically assisted procedure performed with image intensifier guidance that reconstructs the coracoclavicular ligaments as well as the acromioclavicular ligaments to achieve bidirectional stability. Repair is achieved with a combination of 2-mm FiberTape (Arthrex, Naples, Florida) and 20-mm Poly-Tape (Neoligaments, Leeds, England) to achieve rigid repair, prevent bone abrasion, and promote tissue ingrowth...

Here, we report the efficacy of the suture bridge technique for treating insertional Achilles tendinosis in an obese and athletic patient. A 48-year-old man presented to our department with a 6-month history of left posterior heel pain. The patient was an athlete (triathlon) and appeared obese (height: 197 cm, body weight: 120 kg, body mass index: 30.9). A diagnosis of insertional Achilles tendinosis was made. Because 6 months of conservative treatments had failed, we performed open resection of the calcaneal exostosis and Haglund's deformity along with debridement of the degenerative tissue of the tendon...

BACKGROUND: Flexor tendon repair failures have primarily been attributed to either core suture rupture or core suture pull out. Recent studies have suggested that knot unravelling may also cause failure of a tendon repair. The aim of this study was to investigate the causes of core suture failure in two types of common flexor tendon repairs. METHODS: Twenty four cadaver tendons were divided into three groups of eight. Each group tested a specific flexor tendon repair...

: Surgical reconstruction of the interosseous membrane may restore longitudinal forearm stability in Essex-Lopresti lesions. This study aimed to compare the longitudinal stability of the intact forearm with a single-bundle and a double-bundle reconstruction of the central band of the interosseous membrane using digital image correlation with a three-dimensional camera system. Single and cyclic axial loading of eight fresh-frozen forearm specimens was carried out in the intact state, after creation of an Essex-Lopresti lesion, after a single-bundle and after a double-bundle reconstruction of the central band using a TightRope(®) (Arthrex GmbH, Munich, Germany) construct...

A positive effect of intra-articular platelet-rich plasma (PRP) injection has been discussed for osteoarthritic joint conditions in the last years. The purpose of this study was to evaluate PRP injection into the trapeziometacarpal (TMC) joint. We report about ten patients with TMC joint osteoarthritis (OA) that were treated with 2 intra-articular PRP injections 4 weeks apart. PRP was produced using the Double Syringe System (Arthrex Inc., Naples, Florida, USA). A total volume of 1.47 ± 0.25 mL PRP was injected at the first injection and 1...

The TightRope RT (Arthrex, Naples, FL) is a suspensory device for anterior cruciate ligament reconstruction. However, there is a potential risk of the button being pulled too far off the lateral femoral cortex into the soft tissue because the adjustable loop is long. The purpose of this article is to present an easy and safe technique for self-flip. As to the preparation of the graft, we draw the first line in the loop of the TightRope RT at the same length as the femoral tunnel, and we draw the second line 7 mm longer than the length of the femoral tunnel as a self-flip line...

UNLABELLED: The efficient and effective function of the Achilles tendon is essential for normal gait and sporting performance. The optimal technique for the operative repair of the Achilles midsubstance rupture remains controversial. Suboptimal outcomes are common even after successful Achilles repair. Factors contributing to poor outcomes include a tenuous soft tissue envelope (leading to wound complications, peritendinous adhesions, and poor tendon healing,) as well as failure to maintain appropriate musculotendinous length, even after successful repair...

PURPOSE: For the success of Latarjet procedure a correct graft positioning is mandatory. Furthermore, the correct screw placement is important to avoid cartilage damage and soft tissue irritation. Due to a cadaveric experimental study, the accuracy of graft and screw positioning utilizing a novel drill guide for a minimal-invasive Latarjet procedure was analyzed. METHODS: Five human fresh-frozen shoulder specimens have been treated in accordance with the Congruent-Arc Latarjet technique using the glenoid bone loss set (Arthrex, Naples, FL, USA) with 3...

INTRODUCTION: Osteoporosis is a highly focused issue in current scientific research and clinical treatment. Especially in rotator cuff repair, the low bone quality of patients suffering from osteoporosis is an important issue. In this context, non-biological solutions using PMMA for anchor augmentation have been developed in the recent past. The aim of this study was to evaluate whether augmentation of suture anchors using bio-absorbable osteoconductive fiber-reinforced calcium phosphate results in improved failure load of suture anchors as well...

There is controversy about the treatment for unstable full radial posterior lateral meniscus tears, particularly that involving the posterior root. Some surgeons have advocated repairing these types of meniscus tears using various techniques, but their methods are somewhat technical. We developed the technique for an all-inside repair for full radial posterior lateral meniscus tears using the Meniscal Viper (Arthrex, Naples, FL). A doubled thread is passed through 1 edge of the radial tear by the Meniscal Viper and is kept in place without tying the knot...

BACKGROUND: Inframammary fold reconstruction has scarcely been evaluated in literature. No biomechanical analyses have been performed comparing different reconstructive methods. This evaluation compares the gold-standard suture reconstruction with an intrarib anchor system (Micro BioComposite SutureTak, Arthrex). METHODS: Three analysis groups were compared including 8 Sawbone blocks, 22 embalmed cadaver, and 27 regular cadaver specimens (N = 57). Transient mechanical analysis was performed at 5 N/s using an Instron 5565 test frame...

The transtibial technique is the most relevant among many surgical techniques for posterior cruciate ligament reconstruction, and many types of fixation devices are used for tibial fixation according to the technique and the length of the graft. However, bone density in the fixation areas should be taken into consideration when choosing the fixation device to achieve rigid and stable fixation. However, density is not a substantial issue for anteromedial cortical fixation using a cortical suspension device. We describe tibial fixation with a TightRope RT (Arthrex, Naples, FL), which is a cortical suspension device, in anatomic transtibial posterior cruciate ligament reconstruction...

We describe a percutaneous technique for repair of type II SLAP lesions. Through the Neviaser portal, a spinal needle is used to pass a FiberStick suture (Arthrex, Naples, FL) through the labrum to create 2 mattress sutures that are secured with PushLock anchors (Arthrex). This technique is simple, reproducible, and knotless and requires no cannulas. At the end of the procedure, minimal suture material remains in the joint.

BACKGROUND: The Nice knot is a bulky double-stranded knot. Biomechanical data supporting its use as well as the number of half hitches required to ensure knot security is lacking. MATERIALS AND METHODS: Nice knots with, one, two, or three half-hitches were compared with the surgeon's and Tennessee slider knots with three half hitches. Each knot was tied 10 times around a fixed diameter using four different sutures: FiberWire (Arthrex, Naples, FL), Ultrabraid (Smith and Nephew, Andover, MA), Hi-Fi (ConMed Linvatec, Largo, FL) and Force Fiber (Teleflex Medical OEM, Gurnee, IL)...

BACKGROUND: The acromion index (AI), critical shoulder angle (CSA) and lateral acromion angle (LAA) are predictive for degenerative rotatory cuff tears. Their unfavorable values are associated with a suboptimal deltoid force vector. The aim of this study was to evaluate whether an optimization of the radiological parameters could be achieved through a specific arthroscopic lateral acromion resection (ALAR). MATERIALS AND METHODS: The procedure was performed in eight fresh frozen cadaver shoulders...
