TFCC, intracapsular suture repair
In this study, the incidence of thread knots in the group A (28.57%) was significantly higher than that in the group B (0%), and the difference was statistically significant (A new arthroscopic intracapsular suture repair technique called outside-in transfer, the all-inside repair was used for Palmer type 1B Atzei class 1 TFCC tears in this study. This new method is a modification of the technique for meniscal tears by Wang in 2019 [One patient with Palmer type 1B TFCC tear was operated using the outside-in transfer, all-inside technique. Several suture techniques are available for Palmer type 1B Atzei class 1 TFCC tears. The currently used techniques of arthroscopic repair for class 1 tears include the inside-out, outside-in, or all-arthroscopic technique [As in knee arthroscopy, an all-inside technique should be fast and safe to use and avoid the disadvantages of the other techniques. A study by Conca et al. in 2003 described an all-inside repair technique for Palmer type 1B TFCC tears using a small suture hook and three portals [A new arthroscopic intracapsular suture repair technique called outside-in transfer, all-inside repair was used for Palmer type 1B Atzei class 1 TFCC tears in this study. This new method is a modification of the technique for meniscal tears introduced by Wang et al. [
