Table 4.
Mean±SD for the imaging outcomes between the patients categorized as symptomatic compared to the asymptomatic patients using the KOOS-pain score at 7 years. WORM Score difference (Sx–Ctl), OARSI Radiographic Score difference (Sx–Ctl) and mJSW difference (Sx–Ctl, mm). Sx=surgical knee; Ctl=contralateral control knee. *indicates a significant difference between groups.12
| Outcome Measure | Symptomatic Patients (Mean±SD) | Asymptomatic Patients (Mean±SD) | p-value |
|---|---|---|---|
| WORM Score* | 13.7±22.2 | 5.8±14.5 | .047 |
| OARSI Xray Score | 2.8±5.0 | 0.8±1.9 | .051 |
| mJSW (mm) | −0.32±0.68 | −0.03±0.182 | .487 |
OARSI = Osteoarthritis Research Society International; WORM = Whole Organ MRI; mJSW = medial joint space width.
