Bone production measurements at macroscopic and microscopic level.
| Bone type evaluation | DCFGP (n = 8; Median (Minimum-Maximum)) | Commercial DBM (n = 8; Median (Minimum-Maximum)) | P (Mann-Whitney U test) |
|---|---|---|---|
| Macroscopic union* | 2(2-3) | 2(2-3) | 0.6 |
| Microscopic evaluation† | 5 (5-7) | 4 (4-6) | 0. 1 |
↵* Complete union (+3 score), presence of cartilage (+2 score), soft tissue or cracks within the defect indicating a possible unstable union (+ 1 score), complete instability at the defect site indicating nonunion (0 score)
↵† Empty (0 score), fibrous tissue only (1 score), more fibrous tissue than fibrocartilage (2 score), more fibrocartilage than fibrous tissue (3 score), fibrocartilage only (4 score), more fibrocartilage than bone (5 score), more bone than fibrocartilage (6 score) and bone only (7 score)
