| Number of lesions at followup | 50 | 64 |
| Duration of followup (months)† | 23.7 (16.0–32.0) | 52.0 (45.0–60.0) |
| Average age at surgery (years)† | 12.2 (12.0–12.3) | 13.1 (12.3–14.8) |
| Lesion locations | ||
| MFC (%) | 26 (52.0) | 60 (93.7) |
| LFC (%) | 24 (48.0) | 4 (6.3) |

* Analysis restricted to studies reporting on specific outcome data for juvenile osteochondritis dissecans lesions; †values are a weighted average of studies reporting on juvenile osteochondritis dissecans outcomes with ranges in parentheses; MFC = medial femoral condyle; LFC = lateral femoral condyle.
