Fig. (3) Physical Examination at 15 weeks post-operatively for all treatment groups. All values represent changes in these parameters from the baseline measurements at the time of surgery. Positive values indicate an increase in flexion or extension from baseline. Negative values indicate a loss of flexion or extension from baseline. Error bars represent standard error. * indicates a significant difference between the SPONGE and SUTURE groups (p < 0.01); † indicates a significant difference between the CPC and SUTURE groups (p < 0.01); and ♠ indicates a significant difference between the INTACT and SUTURE groups (p < 0.01).
