AI Article Synopsis
- The study evaluates the biomechanical properties of three rotator cuff repair techniques: Medially Knotted Suture Bridge (KSB), Medially Untied Suture Bridge (USB), and Modified Suture Bridge (MSB).
- The Modified Suture Bridge showed the best results, with the highest load to failure, greater stiffness, and least elongation compared to the other techniques.
- All techniques ultimately failed due to suture pulling through the cuff tendon, but the MSB technique may offer superior performance in arthroscopic rotator cuff repair.
Article Abstract
. To compare the biomechanical properties of 3 suture-bridge techniques for rotator cuff repair. . Twelve pair-matched fresh-frozen shoulder specimens were randomized to 3 groups of different repair types: the medially Knotted Suture Bridge (KSB), the medially Untied Suture Bridge (USB), and the Modified Suture Bridge (MSB). Cyclic loading and load-to-failure test were performed. Parameters of elongation, stiffness, load at failure, and mode of failure were recorded. . The MSB technique had the significantly greatest load to failure (515.6 ± 78.0 N, = 0.04 for KSB group; < 0.001 for USB group), stiffness (58.0 ± 10.7 N/mm, = 0.005 for KSB group; < 0.001 for USB group), and lowest elongation (1.49 ± 0.39 mm, = 0.009 for KSB group; = 0.001 for USB group) among 3 groups. The KSB repair had significantly higher ultimate load (443.5 ± 65.0 N) than USB repair (363.5 ± 52.3 N, = 0.024). However, there was no statistical difference in stiffness and elongation between KSB and USB technique ( = 0.396 for stiffness and = 0.242 for elongation, resp.). The failure mode for all specimens was suture pulling through the cuff tendon. . Our modified suture bridge technique (MSB) may provide enhanced biomechanical properties when compared with medially knotted or knotless repair. . Our modified technique may represent a promising alternative in arthroscopic rotator cuff repair.

How I do it: using physics and progressive defect tensioning to close large hernia defects during MIS ventral hernia repair.

Introduction: Closure of large hernia defects with minimally invasive surgery has long-been a challenge. Barbed sutures have helped us bridge this technical gap, but their off-label use is not well studied.
Materials And Methods: We describe a suturing technique for minimally invasive ventral hernia repair (MIS-VHR) termed "progressive defect tensioning" and explore its theoretical advantages.

Introduction Sutureless enterostomy is used as an effective technique for constructing an enterostomy in very low and extremely low birth weight infants in Japan. Sutureless enterostomy is a separate type of enterostomy procedure for low birth weight infants. We adapted this technique and developed sutureless loop enterostomy (SLE), an approach without a skin bridge in which the intestinal wall is not sutured to the abdominal wall.

At present, suture bridge is a feasible choice in the treatment of massive rotator cuff tears (MRCTs). However, high tension on the repair site and medial tension during suture tightening and after medial knotting are unavoidable problems in MRCT repair with a suture bridge. Arthroscopic V-shaped double-pulley suture-bridge repair is a pragmatic surgical technique for the repair of MRCTs.

Purpose: To use a finite element method to construct a patch-bridge repair model for massive rotator cuff tears (MRCTs) and investigate the effects of different suture methods and knot numbers on postoperative biomechanics.
Methods: A finite element model based on intact glenohumeral joint data was used for a biomechanical study. A full-thickness defect and retraction model of the supraspinatus tendon simulated MRCTs.
Editorial Commentary: Anterior Cruciate Ligament Repair Could Be Indicated in Older, Less Active Patients.

Anterior cruciate ligament (ACL) injuries do not heal anatomically on their own and often lead to post-traumatic osteoarthritis (PTOA). ACL reconstruction, though effective, can contribute to PTOA, and donor site morbidity remains a concern with autografts. While ACL repair has traditionally shown poorer outcomes (27% failure rate in the 1990s and early 2000s), a recent review of newer techniques shows promising results and no significant differences in patient-reported outcomes between repair and reconstruction.
