Scoresheet for the semi-quantitative evaluation of the in-vivo Micro-Computed Tomography (µCT) (Xtreme CT II) scans.
Parameter | Score 0 | Score 1 | Score 2 |
---|---|---|---|
Scaffold position | Scaffold completely inside the cancellous condyle | Scaffold mostly (>50%) in the cancellous condyle, partially in the medullary cavity | Scaffold partially in the cancellous condyle, mostly (>50%) in the medullary cavity |
Scaffold demarcability | Scaffold cannot be separated from surrounding bone tissue |
Scaffold partially separable from surrounding bone tissue |
Scaffold can be completely separated from surrounding bone tissue |
Scaffold degradation | Scaffold size | Scaffold size | Scaffold size |
h ≤ 2.5 mm | 2.5 mm < h < 4.5 mm | h ≥ 4.5 mm | |
∅ ≤ 2 mm | 2 mm < ∅ < 3.5 mm | ∅ ≥ 3.5 mm | |
Scaffold-bone-contact | Broad contact area between scaffold and surrounding bone, numerous trabeculae grown onto the scaffold, no gap visible | Several bone trabeculae between scaffold and surrounding bone, hardly visible gap | No contact between scaffold and surrounding bone, clear gap between bone and scaffold |
