Donor-to-recipient cartilage thickness ratios evaluated in the finite element models

Configuration	D/R thickness ratios	Number
Recipient-side thicker (D/R < 1)	0.33, 0.50, 0.67, 0.80	4
Thickness matched (D/R = 1)	1.00	1
Donor-side thicker (D/R > 1)	1.25, 1.50, 2.00, 3.25	4

Nine donor-to-recipient (D/R) cartilage thickness ratios were modeled to evaluate the effect of geometric mismatch on local-interface 95th percentile strain outcomes. Recipient cartilage thickness was held at 2 mm, and donor cartilage thickness was varied to produce the listed D/R ratios
