Early isolated triangular fibrocartilage complex tears: management by arthroscopic repair

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Hand Surgery

Background:

• Traumatic triangular fibrocartilage complex (TFCC) tears often result from wrist hyperextension or distraction injuries.
• These injuries are frequently associated with ulnar wrist pain and functional limitations in daily activities, work, and sports.

Purpose of the Study:

• To evaluate the efficacy of arthroscopic repair for peripheral tears of the triangular fibrocartilage complex (TFCC).

Main Methods:

• A cohort of 37 patients with peripheral TFCC tears underwent arthroscopic repair using the inside-out technique.
• The distal radioulnar joint was stabilized with a Kirschner wire for six weeks post-surgery.
• Patients were followed for an average of 25.6 months, with outcomes assessed using the Mayo Modified Wrist Score.

Main Results:

• 92% of patients (34 out of 37) reported satisfactory outcomes, returning to work or sports.
• Excellent or good results were achieved in 34 patients (92%).
• Mild pain during activity was reported by four patients, with preserved wrist motion and at least 72% grip strength compared to the contralateral hand.

Conclusions:

• Arthroscopic repair is a successful treatment for peripheral TFCC tears.
• The procedure effectively alleviates pain and improves wrist function, enabling a return to demanding activities.
