This prospective randomized clinical trial evaluates the effectiveness of a Fast Fix-enhanced arthroscopic system compared with conventional arthroscopic suturing for temporomandibular joint disc repositioning in patients with TMJ internal derangement. Patients are randomly allocated into two groups and assessed for functional improvement (maximum mouth opening), pain reduction, joint symptoms, and surgical performance outcomes over a 6-month follow-up period. The study aims to determine whether the Fast Fix-enhanced technique provides superior clinical, functional, and surgical outcomes compared to conventional arthroscopic suturing
