    Tissue-Engineered Tendon for Enthesis Regeneration in a Rat Rotator Cuff Model.
    Biores Open Access 2017 1;6(1):47-57. Epub 2017 Jun 1.
    Department of Biomedical Engineering, University of Michigan, Ann Arbor, Michigan.
    Healing of rotator cuff (RC) injuries with current suture or augmented scaffold techniques fails to regenerate the enthesis and instead forms a weaker fibrovascular scar that is prone to subsequent failure. Regeneration of the enthesis is the key to improving clinical outcomes for RC injuries. We hypothesized that the utilization of our tissue-engineered tendon to repair either an acute or a chronic full-thickness supraspinatus tear would regenerate a functional enthesis and return the biomechanics of the tendon back to that found in native tissue.

    Today's sutures are the result of a 4000-year innovation process with regard to their materials and manufacturing techniques, yet little has been done to enhance the therapeutic value of the suture itself. In this review, we explore the historical development, regulatory database and clinical literature of sutures to gain a fuller picture of suture advances to date. First, we examine historical shifts in suture manufacturing companies and review suture regulatory databases to understand the forces driving suture development. Read More

    Tensile strength of the pullout repair technique for the medial meniscus posterior root tear: a porcine study.
    Int Orthop 2017 Jul 14. Epub 2017 Jul 14.
    Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, 2-5-1 Shikata-cho, Kita-ku, Okayama, 700-8558, Japan.
    Purpose: The purpose of this study was to compare the load-to-failure of different common suturing techniques with a new technique for the medial meniscus posterior root tear (MMPRT).

    Methods: Thirty porcine medial menisci were randomly assigned to three suturing techniques used for transtibial pullout repair of the MMPRT (n = 10 per group). Three different meniscal suture configurations were studied: the two simple suture (TSS) technique, the conventional modified Mason-Allen suture (MMA) technique, and the new MMA technique using the FasT-Fix combined with the Ultrabraid (F-MMA).

    Posterior suture annuloplasty for functional tricuspid regurgitation.
    Ann Cardiothorac Surg 2017 May;6(3):262-265
    Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.
    Functional tricuspid regurgitation (TR) is primarily caused by enlargement of the tricuspid annulus due to right ventricular dilation, frequently secondary to left sided valvular disease. Early techniques for the treatment of functional TR were introduced by Jerome Kay in 1965 and Norberto DeVega in 1972. Modified suture annuloplasty is a modification of DeVega's semicircular purse string technique, however, it is based on Kay's principle of obliteration of the posterior segment of the annulus only.

    Taos Orthopaedic Institute, Taos, New Mexico, U.S.A.
    Tear of the meniscal root results in loss of circumferential hoop tension in the meniscus and increased tibiofemoral contact pressure, leading to cartilage wear. Repair of the meniscal root can restore function of the meniscus. Many techniques for root repair have recently been described. Read More

    Pectoralis Major Repair With Unicortical Button Fixation And Suture Tape.
    Arthrosc Tech 2017 Jun 5;6(3):e729-e735. Epub 2017 Jun 5.
    Steadman Philippon Research Institute, Vail, Colorado, U.S.A.
    Although injuries of the pectoralis major muscle are generally uncommon, ruptures of the pectoralis major are occasionally seen in younger, more active patients who participate in weightlifting activities. These injuries usually occur during maximal contraction of the muscle, while in extension and external rotation. In the case of a rupture, operative treatment is advocated especially in young, active patients regardless of the chronicity of the injury. Read More

    Medial Meniscus Posterior Root Repair Using a Transtibial Technique.
    Arthrosc Tech 2017 Jun 1;6(3):e511-e516. Epub 2017 May 1.
    Department of Orthopedic Surgery and the Sports Medicine Center, Mayo Clinic and Mayo Foundation, Rochester, Minnesota, U.S.A.
    The meniscal roots are critical in maintaining the normal shock absorbing function of the meniscus. If a meniscal root tear is left untreated, meniscal extrusion can occur rendering the meniscus nonfunctional resulting in degenerative arthritis. Two main repair techniques are described: (1) suture anchors (direct fixation) and (2) sutures pulled through a tibial tunnel (indirect fixation). Read More

    Low incidence of failure after proximal biceps tenodesis with unicortical suture button.
    J Orthop 2017 Sep 27;14(3):384-389. Epub 2017 Jun 27.
    Orthopaedic Surgery Department, Winn Army Community Hospital, 1061 Harmon Ave., Fort Stewart, GA 31324, United States.
    Purpose: Recent interest in suture button fixation has developed with regard to proximal biceps tenodesis fixation. Biomechanical studies have demonstrated viability of a unicortical suture button technique in vitro. Despite this, no clinical data has been reported to validate the biomechanical data. Read More

    Impact of new technologies and experience on procedural aspects of surgical aortic valve replacement - a process analysis.

    Department of Cardiovascular Surgery, University Hospital Geneva, Switzerland.
    Background: Surgical aortic valve replacement (SAVR) is the treatment of choice in severe symptomatic aortic valve disease. New techniques and prostheses have been recently developed to facilitate the procedure and reduce aortic cross-clamp time (AOx). The aim of this study was to analyse the different procedural steps in order to identify the most time-consuming part during aortic clamping time and to compare impact of experience on procedural aspects.

    Laparoscopic Suturing as a Barrier to Broader Adoption of Laparoscopic Surgery.
    JSLS 2017 Jul-Sep;21(3)
    Franchise Health Economics and Market Access, Ethicon, Inc., Somerville New Jersey, USA.
    Background: Laparoscopic surgery is increasingly replacing the open procedure because of its many patient-related benefits that are well aligned with policies and programs that seek to optimize health system performance. However, widespread adoption of laparoscopic surgery has been slow, in part, because of the complexity of laparoscopic suturing. The objective of this study was to review the clinical and economic impacts of laparoscopic suturing in key procedures and to assess its role as a barrier to the broader adoption of laparoscopic surgery.
