Drop in survivorship 13 years after AMIC procedures in aligned knees: A long-term follow-up.

Purpose: Autologous matrix-induced chondrogenesis (AMIC) showed promising short-term results comparable to microfracture. This study aims to assess the 19-year outcomes of AMIC, addressing the lack of long-term data.

Methods: Retrospective cohort of 34 knees treated with AMIC underwent a 19-year follow-up.
