Fig. (4) Synovial thickness as measured by MRI at 15 weeks post-operatively for all treatment groups. Infrapatellar synovial thickness was
not significantly different when comparing suture and intact groups (p=0.9063). The CPC and Sponge groups approached significance
(p=0.0665), and all groups showed no significant differences when compared to intact knees (p>0.1). All values represent changes in these
parameters from the baseline measurements at the time of surgery. Error bars represent standard error.
