Posterior Arthroscopic Subtalar Joint Arthrodesis (Pasta).

The arthroscopic approach provides a manageable postoperative course in terms of wound healing, pain control, and bone healing when compared with an open procedure. In particular, posterior arthroscopic subtalar joint arthrodesis (PASTA) allows a reproducible and viable alternative to standard lateral-portal subtalar joint (STJ) arthrodesis without violating sinus or canalis tarsi neurovascular structures. Additionally, those patients who have undergone previous total ankle arthroplasty, arthrodesis, or talonavicular joint arthrodesis may be better served with PASTA over open arthrodesis if STJ fusion becomes necessary. This article describes the unique PASTA surgical procedure and its helpful tips and pearls.
