A Prospective Randomized Clinical Trial Comparing a Fast-Fix-Enhanced Arthroscopic System Versus Conventional Arthroscopic Suturing for Temporomandibular Disc Repositioning in Internal Derangement: Functional, Clinical, and Surgical Outcomes

A Prospective Randomized Clinical Trial Comparing a Fast Fix Enhanced Arthroscopic System Versus Conventional Arthroscopic Suturing for Temporomandibular Disc Repositioning in Internal Derangement: Clinical, Functional, and Surgical Outcomes

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

Inclusion Criteria.

• Age ≥ 18 years.
• Both sexes.
• Patients with TMJ internal derangement (disc displacement without reduction).
• Patients indicated for arthroscopic disc repositioning following failure of conservative management.

Exclusion Criteria

• Previous TMJ surgery on the affected joint.
• Rheumatoid arthritis, systemic inflammatory joint disease, or other TMJ pathology (tumor, fracture, infection)
• Severe degenerative joint disease (osteoarthritis grade V) or ankylosis.
• Patients are unable to comply with follow-up assessments or MRI evaluation.
• Patients with TMDS are secondary to malocclusion.
