Values are given as mean and standard deviation. Pretraining magnetic resonance images were obtained 3 weeks (mean, 22.9 ± 3.9 days) after surgery. Post-training images were obtained 15 weeks (mean, 107.6 ± 7.7 days) after surgery. The images taken for the 1-year measurements were obtained a mean of 368.1 ± 18.2 days after surgery.
