Anterior cruciate ligament (ACL) rupture is a common injury of the knee. Arthroscopic ACL reconstruction is a standard treatment for this condition. All-inside ACL reconstruction has many advantages compared with conventional techniques. However, there are still concerns regarding graft elongation and stability with all-inside ACL reconstruction. Here, we propose an arthroscopic technique using the shortening strands of a flexible suspensory button as an internal brace. This method provides the advantages of increased stability and ACL graft protection while using the same implant as the all-inside ACL reconstruction technique.
Meniscus root tear leads to circumferential hoop tension loss and increases femorotibial contact force, which causes irreversible cartilage degeneration. Biomechanical studies have shown that meniscus root repair provides better femorotibial contact force than meniscectomy. Many techniques for meniscus root repair have been published in recent years. The soft suture anchor is widely used in the glenoid labral repair. It is a small low-profile soft anchor. This article presents a new and simple technique of lateral meniscus root repair using the small soft anchor, which results in an anatomic and more vertical anchor position. It avoids instrument-related complications, such as cartilage delamination, material reaction, metal retention, and hard suture anchor pullout.
There are many types of sliding locking knots used in arthroscopic surgery. Each type has its advantages and disadvantages. This technical note describes a new sliding locking knot, the Chula knot. This knot has been used for arthroscopic shoulder surgery in more than 500 cases at our hospital. The Chula knot has a special property in that it can be unfastened and retightened in case of premature locking and unintended loop loosening. This retensioning ability cannot be found in other configurations of arthroscopic knots. The Chula knot also has other benefits: It has high ultimate tensile strength and is easy to tie.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
