Design outcomes

Primary

Measure	Time frame
After 3 months, patients with TFCC resection have significantly better results (at least 1 VAS point, 10%) of their pain on excertion than patients with TFCC debridement	—

Secondary

Measure	Time frame
1. Ulnocarpal wrist pain on excertion improves significantly and by at least 2 VAS points after 3 months in both groups 2. Krimmer wrist score improves significantly and by more than 10 points after 3 months in both groups 3. DASH-Score improves significantly and by more than 10 points after 3 months in both groups 4. Within 2 years from arthroscopy, patients with TFCC resection need significantly less reoperations (Repeat arthroscopy or ulna shortening) than patients with TFCC debridement	—
