A novel technique of all-inside arthroscopic triangular fibrocartilage complex repair

Peripheral triangular fibrocartilage complex (TFCC) tears are amenable to repair. Limitations of current repair techniques include prolonged recovery and button or knot intolerance. We present a novel technique of an all-inside repair using existing technology (FasT-Fix; Smith & Nephew Endoscopy, Andover, MA) to circumvent these complications. This technique is faster, easily performed, safe, and potentially stronger than current repairs. Earlier motion and rehabilitation are instituted after this repair. The tear is debrided to stimulate angiogenesis. The FasT-Fix is inserted through the 3-4 portal with the arthroscope in the 6R portal. The first poly-L-lactic acid block is deposited peripheral to the tear. Upon penetration of the wrist capsule, a distinct decrease in resistance is felt. The introducer is withdrawn, depositing the block outside the capsule. The trigger on the introducer advances the second block into the deployment position. It is advanced and deposited central to the tear, forming a vertical mattress configuration. The introducer is removed, leaving the pre-tied suture. The knot is tightened and cut by use of the knot pusher/cutter. Multiple implants may be inserted to complete the repair. Postoperative care involves a sugartong splint for 2 weeks followed by a short arm cast for 4 weeks. Range of motion is begun thereafter with strengthening started at 10 weeks.
