Table 1.

Flexion and extension measurements for SUTURE and SCAFFOLD treatment groups (mean±SD) before and after surgery are shown. Mean difference and p-values are listed. Both groups experienced a significant loss of terminal extension after surgery that was not treatment-specific. There were no significant differences between the SUTURE and SCAFFOLD groups for any of the measured physical exam parameters.

	SUTURE (n=8)		SCAFFOLD (n=8)
	Pre-op	13 wk post-op	Pre-op	13 wk post-op
Extension (deg)	43.8±5.2	37.5±4.6*	45.0±7.6	38.1±5.3*
Flexion (deg)	142.5±4.6	136.3±12.7	142.5±4.6	135±15.8
Lachman (mm)	3.0±0.8	3.5±1.8	3.0±0.8	4.0±2.1

^*p = 0.02 for the change in Extension angle with time for both the SUTURE and SCAFFOLD groups.
