Summary of dGEMRIC T1 values (msec) separated by subjects with complete followup and those who missed their 2-year followup visit
| Patients with 1 year of followup (n = 9) | Patients with 2 years of followup (n = 28) | p value | |
|---|---|---|---|
| Superficial zone | |||
| Preoperative | 496 (± 140) | 474 (± 137) | 0.38 |
| Year 1 | 436 (± 140) | 401 (± 111) | 0.13 |
| Year 2 | 451 (± 115) | ||
| Deep zone | |||
| Preoperative | 558 (± 123) | 579 (± 150) | 0.54 |
| Year 1 | 551 (± 163) | 518 (± 132) | 0.18 |
| Year 2 | 537 (± 121) | ||
Plus/minus values are between-subject SDs of the total dGEMRIC values, ie, averaged over all 10 regions measured within each patient; p values describe the significance of the difference in measurements between subjects with only 1 year of followup versus those with 2 years of followup; dGEMRIC = delayed gadolinium-enhanced MRI of cartilage.
