Range of Motion (PIP, DIP), Eextension and Strain at 20 N, and Gap for Normal, Repair-only, Scaffold, and ASC+BMP12 Groups
| Sample Size | PIP (degrees) | DIP (degrees) | Ext. @ 20N (mm) | Strain @ 20N | Gap (mm) | |
|---|---|---|---|---|---|---|
| Normal | 25 | 31.7±10.0a | 23.3±6.0a | |||
| Repair-only | 8 | 24.4±14.9 | 16.9±7.1 | 0.46±0.16 | 3.1±1.1 | 0.2±0.3a |
| Scaffold | 15 | 20.8±12.0a | 14.4±8.6a | 0.58±0.21 | 3.8±1.4 | 1.1±0.8a |
| ASC+BMP12 | 10 | 15.7±9.9a | 20.0±5.5 | 0.57±0.17 | 3.3±1.1 | 0.8±0.7 |
PIP, DIP: joint rotations under 1.5N of load. Ext./Strain @ 20N: extension/strain of tendon under 20N of tensile load. Gap: Distance between tendon stumps at the time of dissection.
