Arthroscopic all-inside repair of Palmer type 1B triangular fibrocartilage complex tears: a technical note

Arthroscopic repair of peripheral dorso-ulnar triangular fibrocartilage complex (TFCC) lesions is now a preferred method. Both outside-in and inside-out techniques are commonly performed for repairing Palmer type 1B TFCC tear. But these techniques have disadvantages of making an additional skin incision to tie knots subcutaneously over the capsule. We performed an arthroscopic all-inside repair technique of Palmer type 1B TFCC tears, which is a modified method of the outside-in technique using a spinal needle. This all-inside technique is as simple as previously described arthroscopic techniques and also has advantages of vertical mattress suture and no additional incision. We recommend this technique as a useful alternative to the others for repairing Palmer type 1B TFCC tear.
