This retrospective study was conducted in Hospital of Chengdu University of Traditional Chinese Medicine. 38 Palmer type 1B TFCC injury patients between August 2017 and June 2020 were enrolled in this study cohort. The patient was positioned for standard wrist arthroscopy using a standard traction apparatus. To probe and evaluate TFCC tears, the 3–4, 4R, and 6R portals were routinely performed. This new repair technique for subtype Palmer type 1B Atzei class 1 TFCC tears requires the needle of a 10-mL sterile syringe, an arthroscopic retriever, a knot pusher, and suture material. A 2.7-mm 30° arthroscope was used to the visualize TFCC tear via 3 or 4 portals, and the probe was inserted through the 6R portal to check and assess the tear parameter of the TFCC, including the site, size, pattern, stability, tissue quality, and associated pathology in the wrist joint. Before sewing, the tear site of the TFCC was debrided with a 2.9-mm full-radius motorized shaver until bleeding to remove the proliferative synovial tissue and encourage healing through the 6R portal. Then, the group A was sutured from the outside to the inside, the group B was sutured with the outside-in transfer, all-inside repair technique to repair the TFCC tear (Additional file A needle of 10 ml sterile syringeSuture method using a needle and suture.
