Sufficient Cartilage for Most Talar Articular Defects Can Be Harvested From the Non-Loadbearing Talus: A Cadaveric Analysis.

ABSTRACT:

Purpose

To assess the quantity of morselized cartilage that can be harvested from the non-load-bearing portion of the talus for immediate reimplantation.

Methods

Non-load-bearing talar cartilage was harvested from 5 cadaveric specimens using a standard arthroscopic approach. Cartilage was separated from the talus in maximum dorsiflexion at the junction of the talar head and neck, grasped, and morselized into a graft using a cartilage particulator. The volume of reclaimed cartilage was measured, and the extrapolated area of coverage was compared to average osteochondral lesions of the talus previously reported.

Results

The total yield of cartilage graft following processing that was obtained from 5 ankle joints ranged from 0.3 mL to 2.1 mL with a mean volume of 1.3 ± 0
