Acute ruptures of the Achilles tendon are a common injury, and debate has continued in published studies on how best to treat these injuries. Specifically, controversy exists regarding the surgical approaches for Achilles tendon repair when one considers percutaneous versus open repair. The present study investigated the biomechanical strength of 3 different techniques for Achilles tendon repair in a cadaveric model. A total of 36 specimens were divided into 3 groups, each of which received a different construct...

Reconstruction of unstable syndesmotic injuries is not trivial, and there is no generally accepted treatment guidelines. Thus, there still remain considerable controversies regarding diagnosis, classification and treatment of syndesmotic injuries. Syndesmotic malreduction is the most common indication for early re-operation after ankle fracture surgery, and widening of the ankle mortise by only 1 mm decreases the contact area of the tibiotalar joint by 42%. Outcome of ankle fractures with syndesmosis injury is worse than without, even after surgical syndesmotic stabilization...

Sleeve gastrectomy operations have become popular among restrictive obesity surgeons, due to its effectiveness for losing weight and acceptable complication rates. However, leakage is a significant problem in these operations. In this ex vivo study, we tried to understand mechanisms of leakage and to examine the effects of two different types of frequently referred reinforcement techniques using sutures. The resected gastric specimens that were removed during sleeve gastrectomy operations were used in this ex vivo study...

It has been proved by many researchers in the last few years that arthroscopic capsulolabral repair is an efficient method for surgical management of anteroinferior shoulder instability. Different arthroscopic techniques using different fixation devices and constructs have been described in the literature, but the suture anchors were the most used implants to shift the inferiorly displaced capsulolabral complex and fix it to the glenoid. In the majority of these techniques, the anchors concentrate the load at specific points (e...

Acromioclavicular joint injuries are one of the most common shoulder injuries, and there are a variety of treatment options. Recently, there have been newer arthroscopic techniques that have addressed coracoid and clavicle fracture risk by using a knotted suture-button fixation through a single, small bone tunnel with additional looped soft-tissue graft stabilization. Although clinical outcomes have been good to excellent, there have still been instances of knot and hardware irritation. The described technique builds on the latest advances and achieves an anatomic coracoclavicular (CC) reconstruction through a single knotless CC fixation device with additional soft-tissue allograft reconstruction of the CC ligaments...

Despite recent advances in knotless suture devices for arthroscopic surgical procedures, arthroscopic knot tying remains a necessary skill for the arthroscopic surgeon. Successful completion of arthroscopic knot tying relies on a thorough understanding of the chosen technique, proper suture management, adequate knot tensioning and securement, and the ability to reproducibly create the knot. We introduce a technique that serves as both a sliding and locking knot while being simple to master and reproducible to perform...

PURPOSE: Two-stage minimally invasive esophagectomy (MIE) has gained popularity in the surgical treatment of esophageal cancer. MIE's limitation is embedded in the construction of intrathoracic anastomosis. Various anastomotic techniques have been reported; however, the mechanical one remains the most commonly adopted. This pilot study aims to describe an efficient, safe, and reproducible way of performing a hand-sewn intrathoracic esophagogastric anastomosis in conjunction with short-term results using 2D and 3D thoracoscopic approaches...

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: Barbed suture use has become more popular as technology and materials have advanced. Minimal data exist regarding performance of the 2 commercially available products, V-LocTM and StratafixTM in tendon repairs. The purpose of this study was to compare gap resistance and ultimate tensile strength of both suture materials and nonbarbed suture in a porcine ex vivo model. Methods: Porcine flexor tendons were harvested and divided into 3 groups of 10 of varying suture material (3-0 PDS™, 3-0 V- V-Loc 180™, or 3-0 Stratafix™)...

BACKGROUND: Wound closure is key to prevent infection, facilitate immediate rehabilitation, and improve efficiency of total knee arthroplasty (TKA). Continuous knotless suturing with barbed suture can potentially save time and distribute tension more evenly. However, its role in TKA in terms of cost-effectiveness and wound complications is not clear. This study aims at comparing barbed and traditional sutures' wound closure time and cost in primary TKA. METHODS: One hundred nine knees were randomized into either barbed or traditional group...

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.

Removal of a chest tube drain could be distressful experience for many patients. Pain, unsightly scar, and possible complications such as pneumothorax are common after the removal of a chest tube. A new method of chest drain wound closure using knotless suture material has been employed, which could alleviate pain and unsightly scar. This suture utilizes a unidirectional anchoring barb, which eliminates the need to tie and does not slip back. This new method of wound closure for chest tube site is a convenient method with advantages of leaving a less unsightly scar and less pain during the chest tube removal process...

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...

To perform a proper labral repair, most surgeons use anchors to secure the labrum to the acetabular bone. We aim to describe a technique for labral repair with a knotless tensionable suture anchor. This technique uses a looped suture configuration, allowing selective tensioning of the repair to maintain the anatomic suction seal of the hip. The use of this technique is easily reproducible and reduces the surgical time compared with previous techniques.
