Comparison of Twelve-Week Repairs with Normal Control Group and Respective Time-Zero Groups

		Unaugmented Repairs*		Augmented Repairs*
	Normal Controls*	Time Zero	12 Weeks	Time Zero	12 Weeks
Cross-sectional area (mm2)	32 ± 2	NA	59 ± 20†	NA	129 ± 34†
Stiffness (N/mm)	515 ± 141	214 ± 72†	199 ± 53†	207 ± 39†	243 ± 45†
Ultimate load (N)	1595 ± 285	668 ± 146†	990 ± 386†	801 ± 145†	1223 ± 316†‡

^*The values are given as the mean and the standard deviation. Each group had eight samples except for ultimate load testing in both the unaugmented group at twelve weeks (seven samples) and the augmented group at twelve weeks (six samples). NA = not available.

^†Compared with normal controls, the difference was significant (p < 0.05).

^‡Compared with augmented time-zero group, the difference was significant (p = 0.016).
