BACKGROUND: The role of platelet-rich plasma (PRP) in the treatment of sport-related injuries is unclear, largely due to the heterogeneity of clinical results. This may relate to compositional differences in PRP from different separation systems. QUESTIONS/PURPOSES: This study aims to compare the composition of PRP produced with five different commercially available systems, focusing on cellular concentrations and pH. METHODS: Seven donors (41 ± 12 years) provided blood for PRP preparation using five systems (Arthrex Angel, Emcyte Genesis CS, Arteriocyte Magellan, Harvest SmartPrep, and Biomet GPS III)...

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...

BACKGROUND: No general consensus has yet been established for the gold standard treatment of ankle syndesmotic complex injuries. Recent literature has documented the success of ankle tightrope fixation for heterogeneous ankle fracture patterns, resulting in syndesmotic complex injuries. We present a multicentre case series assessing the clinical, radiological and functional outcomes of patients with Weber C ankle fractures treated with the Arthrex TightRope(®) fixation system. METHOD: We performed a retrospective analysis of all adult patients with Weber C ankle fractures who were treated with the Arthrex TightRope(®) fixation system at four centres over a 3-year period...

Despite extensive research, the management of acute ruptures of the Achilles tendon remains an area of controversy, and there is no consensus regarding the optimal treatment. An InternalBrace™ (Arthrex, Inc., Naples, Florida) is a ligament augmentation repair using high strength sutures/tape and knotless bone anchors which encourages healing and allows early mobilization. This article describes, with video illustration, a knotless Achilles tendon repair technique using the InternalBrace™ principle.

Suture button devices such as the TightRope (Arthrex, Naples, Florida) have been increasingly used for syndesmotic fixation of ankle fractures. Despite proposed advantages, prior studies have shown equivalent outcomes, with a theoretical decreased need for removal of hardware. Complications of suture button fixation of syndesmotic instability may be underreported and include lateral suture knot inflammation with or without granuloma formation, infection, aseptic osteolysis with widening of the tibial drill tunnels, heterotopic ossification, and osteomyelitis...

Acute midsubstance Achilles tendon ruptures, which are increasingly common among athletes, can result in significant functional limitations and decreased quality of life when not managed appropriately. The various surgical techniques for treating Achilles ruptures include open repair with Krackow locking sutures, percutaneous repair, and limited-incision repair with suture-passing jigs. Less invasive techniques have been developed to optimize the functional benefits of surgery while reducing delayed wound healing, infection, and other postoperative complications...

BACKGROUND: It is usually accepted that acquired flatfoot deformity after injury is usually due to partial or complete tear of the posterior tibial tendon (PTT), with secondary failure of the other structures which maintain the medial longitudinal arch, such as the plantar calcaneo-navicular (SPRING) ligament. It is unusual to find an isolated Spring Ligament (SL) tear, with an intact TP tendon. METHODS: The medial arch reconstruction technique of an isolated SL tear in 5 patients is presented discussed in this paper...

INTRODUCTION: Tension-band wire fixation of patellar fractures is associated with significant hardware-related complications and infection. Braided polyester suture fixation is an alternative option. However, these suture fixations have higher failure rates due to the difficulty in achieving rigid suture knot fixation. The Arthrex syndesmotic TightRope, which is a double-button adjustable loop fixation device utilizing a 4-point locking system using FibreWire, may not only offer stiff rigid fixation using a knotless system, but may also obviate the need for implant removal due to hardware related problems...

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...
