Background: The TFCC is one of many structures on the ulnar aspect of the wrist. TFCC is a critical component of wrist mechanics, serving important functions in both load transmission and DRUJ stability. TFCC tears are common sources of ulnar-sided wrist pain which are frequently diagnosed simply as wrist sprains. Purpose: This study to assess functional outcome of arthroscopic repair of TFCC tears. Methods: During the period between May 2015 and February 2017, we conducted a prospective study to assess functional outcome of arthroscopic management of TFCC tears. The study includes ten patients with torn TFCC (age between 18-60 years). Athletes and non-athletes with failure of conservative treatment in alleviation of patient’s Symptoms after 3 months. They underwent arthroscopic Repair. Presurgery and postsurgery the visual analogue scale (VAS) was recorded for each case. Patient-rated wrist and hand evaluation (PRWHE) scores were determined at baseline (before arthroscopy) and after arthroscopy. The mean duration of follow-up was 10.93 months. Results: The VAS improved from a mean of 6,58to a mean of1,8 and Mean PRWHE total score declined from 49 of 100 at baseline to 25of 100. Conclusion: This study proves that arthroscopic management of TFCC injuries results in a predictable satisfactory functional outcome.
