BACKGROUND: Shoulder disorders, particularly rotator cuff tears, are prevalent musculoskeletal conditions related to aging. Although the widely used suture anchor technique provides strong mechanical support to the tendon, it is associated with a risk of postoperative tendon retearing. The conventionally used titanium alloys can affect the interpretation of magnetic resonance imaging. Degradable magnesium alloys possess excellent biocompatibility, similar mechanical property to the bone, and stimulating bone formation ability from Mg2+ ...

BACKGROUND: Both inlay and onlay arthroscopic biceps tenodesis (ABT) are common procedures performed during rotator cuff repair. The inlay method involves creating a bone socket in the bicipital groove to secure the long head of the biceps tendon (LHBT) using an interference screw. The onlay method utilizes a suture anchor to secure the LHBT on the surface of the bicipital groove. Little is known on the long-term differences in patient reported outcomes (PROs) between these two techniques...

Tibial tubercle avulsion fractures, though rare, pose a significant challenge in pediatric orthopedics, particularly in athletic adolescents. For nondisplaced fractures, conservative treatment involves the use of braces or casts, while displaced fractures necessitate operative intervention, often through screw fixation. Concomitant soft tissue injuries should also be identified and addressed operatively to ensure complete repair of the extensor mechanism. This paper introduces a method for open reduction and internal fixation (ORIF) of tibial tubercle fractures with suture anchor repair of the distal patellar tendon avulsion...

BACKGROUND: The approach to managing the footprint area and reconstructing the tendon-bone interface (TBI) is critical for optimal healing. PURPOSE: To evaluate the outcomes of the semi-bone tunnel (SBT) technique using a double-row suture bridge combined with platelet-rich plasma (PRP) hydrogel for rotator cuff repair in a rabbit model. STUDY DESIGN: Controlled laboratory study. METHODS: A total of 48 New Zealand White rabbits were divided into 4 groups...

OBJECTIVE: Anchoring the fetal membrane to the uterine wall via a novel suture delivery system could reduce the risk of preterm premature rupture of membranes (PPROM) after fetoscopic surgery. This study assesses the feasibility of using a novel device designed for minimally invasive suturing to anchor fetal membranes to the uterine wall and to close surgical defects after fetoscopy. METHODS: We tested the suturing device both ex vivo and in vivo. In the ex vivo studies, 12-French trocar defects were created with a fetoscope in five specimens of human uterine tissue with fetal membranes attached...

BACKGROUND: The T-line hernia mesh is a synthetic, polypropylene mesh specifically designed to prevent anchor point failure by evenly distributing tension through mesh suture extensions. This case series illustrates the first clinical application of the T-line mesh for umbilical hernia repair (UHR). METHODS: This study is a retrospective, consecutive cases series of all adult patients presenting to a single surgeon with symptomatic umbilical hernia requiring surgical repair using the T-line hernia mesh...

Background:  Injuries of the volar ligaments of the wrist are not uncommon, but their arthroscopic treatment presents a significant challenge. The objective of this paper is to introduce a technique for reattaching (in acute injuries) or reinforcing (in chronic injuries) various volar wrist ligaments to the bone, using standard wrist arthroscopic dorsal and volar portals. Methods:  There are three common steps for all the arthroscopic volar capsuloligamentous reattachments or reinforcements Step 1 - Volar Portal Establishment: volar radial, volar ulnar and volar central portals are used depending on which structure needs to be reattached or reinforced...

OBJECTIVE: To explore the early effectiveness of arthroscopic tri-anchor double-pulley suture-bridge in treatment of medium-size supraspinatus tendon tears. METHODS: Between December 2020 and January 2023, 40 patients with medium-size supraspinatus tendon tears were treated with arthroscopic tri-anchor double-pulley suture-bridge. There were 18 males and 22 females, with an average age of 62.6 years (mean, 45-73 years). Among them, 17 patients had trauma history...

There is no consensus on the best surgical technique for treating thumb ulnar collateral ligament (UCL) ruptures. This systematic review and meta-analysis investigates which primary repair technique and postoperative immobilization protocol result in the best clinical outcomes. A literature search was conducted in Embase, Medline ALL Ovid, Web of Science Core Selection and Cochrane Central Register of Controlled Trials. Pain, stability, tip pinch strength, key pinch strength, grip strength, return to work and metacarpophalangeal joint range of motion were collected as postoperative outcomes...

OBJECTIVES: Bankart lesion is one of the most common lesions of the glenohumeral joint. Several double-row suture methods were reported for Bankart repair, which could provide more stability, yet more motion limitation and complications. Therefore, we introduced a new double-row Bankart repair technique, key point double-row suture which used one anchor in the medial line. The purpose of this article is to investigate the clinical outcomes of this new method and to compare it with single-row suture...

BACKGROUND: Despite the fact that meniscocapsular anterior detachment is the most common location of instability in children with a Discoid Lateral Meniscus (DLM), there is a lack of consensus about the type of repair that should be utilized for stabilization. The aim of this study was to determine the best fixation method for anterior detachment of DLM in children. Our hypothesis was that excessive rigidity with fixation would restrict meniscal mobility and increase the rate of failure or prevent full knee flexion...

PURPOSE: To determine the rate of and risk factors for clinical failure and return to military duty following primary patellar tendon repair with either transosseous trunnel repair or suture anchor repair. METHODS: The Military Health System Data Repository (MDR) was queried to identify all adult patients undergoing surgical treatment of a patellar tendon rupture in the Military Health System from 2014 to 2018. Patients who underwent either transosseous tunnel repair or suture anchor repair were included...

INTRODUCTION: The zipper device is a wound closure device that can be directly applied over the intact skin on either side of the wound edges and does not need anchoring into the skin or subcutaneous plane. The noninvasive nature of the zipper device makes it less time-consuming and less painful, but its effectiveness and related complications need to be studied. METHODS: Prospective registration of the protocol followed in this study was done. Electronic databases were searched for relevant articles, and their screening was completed, followed by data extraction and analysis...

Stereotactic electroencephalography (SEEG) is an increasingly popular surgical modality for localizing the epileptogenic zone. Robot-guided stereotactic electrode placement has been covered in Japan by National Health Insurance since 2020. However, several surgical devices, such as the anchor bolt (a thin, hollow, metal shaft that serves as a guide screw or fixing for each electrode), have not been approved. A 14-year-old female who underwent SEEG for intractable epilepsy and required additional surgery to remove a retained depth electrode from the skull after the SEEG monitoring was finished...

Partial Articular Supraspinatus Tendon Avulsion (PASTA) lesions, a subset of partial rotator cuff tears, pose a surgical challenge, disrupting the integrity of the supraspinatus tendon. Transtendinous repair is the preferred choice in young individuals for limiting tear progression and preserving intact high-quality cuff tissue thus preventing tendon shortening, as compared to the tear completion and repair technique. Our approach leverages these advantages, specifically indicated for Ellman's Grade 3 tears and cases where conservative treatments have failed...

BACKGROUND: Mallet finger deformity is a prevalent disability that causes discomfort and inconvenience to the patients. Despite the existence of various surgical approaches, surgical management remains a controversial subject. METHODS: We retrospectively analyzed the clinical data of 26 patients with isolated tendinous mallet fingers who were admitted between January 2021 and June 2022. Among them, there were 18 men and eight women, aged between 20 and 56 years, with an average age of 38 years...

Rotator cuff injury is a common shoulder injury. Arthroscopic repair of rotator cuff tears has become a common way. Suture anchor is a commonly used fixation device. Threading the suture through the rotator cuff tendon is a key step in arthroscopic repair of rotator cuff tears. Common methods of passing suture through the rotator cuff tendon include using a suture hook or rotator cuff suture passer device. However, the suture using suture hook is a kind of reverse suture, and the operation is more troublesome...

The stability of the knee joint is crucially dependent on the integrity of the lateral meniscus posterior root, which is often accompanied by anterior cruciate ligament injury. Anchor suture repair for lateral meniscus posterior root injury not only achieves better biomechanical effects but also ensures favorable prognosis. However, the placement of anchors often requires the establishment of a posterior approach, and the insertion of an anchor is a technical challenge. In light of this, we have applied the technique of reverse anchor fixation for repairing the lateral meniscus posterior root, which not only simplifies the procedure but also effectively reduces the "bungee effect...
