1 A retrospective study of 163 joints in 124 patients demonstrated a longer revision-free joint survival for both MCPJ and PIPJ following PA, compared with two-component alloplastic arthroplasty, although it was a nonsignificant trend. 6 PIPJs resurfaced with perichondrium required fewer revisions and had an increased 10-year survival and median time to revision. 6 However, PA is technically demanding when it comes to obtaining the right curvature of the resurfaced phalanx.
