A Multicenter Randomized Controlled Trial Comparing Platelet-Rich Fibrin and Ventral Dartos Flap as Intermediate Layers in Tabularized Incised Plate (TIP) Urethroplasty for Distal Hypospadias With Mild Penile Curvature

Distal hypospadias is the most common form of hypospadias. The Tubularized Incised Plate (TIP) repair is the standard surgical technique for this condition; however, complications such as fistula formation and meatal stenosis remain concerns. These complications are often influenced by the choice of intermediate tissue layer used to reinforce the neourethra. The traditional ventral dartos flap is effective but can be technically challenging and may result in a bulky tissue layer. Platelet-rich fibrin (PRF) is an autologous, growth factor-rich biological material that has shown promise in tissue regeneration and healing. It is easy to prepare intraoperatively and may serve as a biological reinforcement to reduce postoperative complications. This study aims to provide high-quality evidence comparing the effectiveness of PRF versus the ventral dartos flap in patients with distal hypospadias, specifically those with Grade 1 urethral defects and minimal penile curvature, using a stratified study population to ensure balanced groups.

Prospective G7 Dual Mobility Total Hip PMCF

This is a prospective multi-center clinical evaluation following recipients of the G7 Dual Mobility hip device. The primary objective is to characterize survivorship of the G7 hip at five years post-index procedure. Secondary objectives include documentation of clinical outcomes, safety and radiographic data.

Comparative Analgesic Effect After Total Knee Arthroplasty Between Intraosseous and Peri-articular Injection

The goal of this RCT is to compare analgesic effect after total knee arthroplasty between intraosseous multimodal analgesic agent injection versus periarticular injection. The main question\[s\] it aims to answer are: Does Intraosseous multimodal analgesic cocktail injection have more post-operative analgesic effect than Peri-articular injection in patients who have done TKA (P)? Participants will randomized to intraosseous injection group or peri-articular injection group and will record the 100-mm VAS pain scores for 2 weeks after TKA. Researchers will compare to peri-articular injection group to see pain and functional outcomes after TKA.

Effects of Human Urinary Kallidinogenase on Early Improvement and Functional Outcomes in Acute Ischemic Stroke (TK-SPEED)

The primary purpose of this trial is to evaluate the effects of Human Urinary Kallidinogenase on improvement of neurological outcome, and early cerebral perfusion in acute ischemic stroke.
