Objectives: This in vivo study aims to investigate the effects of Ankaferd Blood Stopper® (ABS) which is a recently developed topical hemostatic agent on tendon healing using a rat Achilles tendon injury model.
Materials And Methods: Twelve male Wistar-Albino rats were used in the study. Right legs of the rats were assigned as the study group, and left legs were assigned as the control group. Under anesthesia, bilateral Achilles tendon injuries were created and repaired surgically. To the surgical sites, 1 mL of ABS for the right side and 1 mL of serum physiologic solution for the left side were applied. Animals were euthanized on the 21st postoperative day, and tendon samples were collected from the extremities. Histological analyses were performed according to the semiquantitative tendon scoring system (Bonar Scale).
Results: Total tendon healing scores were significantly poorer in the study group compared to the control group. Although there were no significant differences between the groups in terms of tenocyte morphology, degree of ground substance staining, and vascularity, the collagen morphology scores were significantly poorer in the study group.
Conclusion: In our study, application of ABS had histologically negative effect on tendon healing in rats. However, further biomechanical and immune histochemical studies are required to support these results.

Background: Failure after rotator cuff repair is typically due to a loss of integrity of the bone-tendon interface. The BioWick anchor (Zimmer-Biomet) is an interpositional scaffold-anchor that was developed to improve tendon-bone healing. The purpose of this study was to determine the clinical efficacy of this novel anchor compared with a standard anchor with respect to retear rates and patient outcomes.

Achilles tendon ruptures are prevalent among physically active adults and can lead to sural nerve injuries (SNIs) due to the anatomical proximity of the sural nerve to the Achilles tendon. While SNIs are well-recognized in surgical contexts, their occurrence following nonoperative treatments, which are often preferred for their lower risk of surgical complications, remains less documented and poorly understood. This report describes a case of a 30-year-old active male who developed chronic traction sural neuropathy after opting for nonoperative treatment of an acute complete Achilles tendon rupture.

Introduction: Tendon injuries represent an ongoing challenge in clinical practice due to poor regenerative capacity, structure, and biomechanical function recovery of ruptured tendons. This study is focused on the assessment of a novel strategy to repair ruptured Achilles tendons in a Nude rat model using stem cell-seeded biomaterial.
Methods: Specifically, we have used induced pluripotent stem cell (iPSC)-derived mesenchymal stem cells (iMSCs) overexpressing the early tendon marker Scleraxis (SCX, iMSC, iTenocytes) in combination with an elastic collagen scaffold.

De Quervain's disease (DQVD) is the stenosing tenosynovitis of tendons in the first extensor compartment of the forearm. It is a common inflammatory condition that is often treated conservatively. While conservative therapy is an effective modality of treatment for a large number of patients suffering from DQVD, some patients do not improve with conservative measures.

Double-bundle (DB) anterior cruciate ligament (ACL) reconstruction has biomechanical advantages over single-bundle reconstruction. However, most studies perform the DB reconstruction with 2 femoral tunnels, which fails to provide an entire femoral footprint for ACL reconstruction. In this study, we describe a femoral double-bundle footprint technique for ACL reconstruction, named the tendon groove technique.
