Factors that influence the rupture pattern
| Factors | Proximal (N = 13) | Mid-substance and distal (N = 11) | Elongated (N = 35) | P value |
|---|---|---|---|---|
| Age (median) | 22 | 20 | 25 | NS |
| Gender (% male) | 62% | 72% | 49% | NS |
| Months out (median) | 30 | 11.5 | 45 | 0.007* |
| Graft type (% autograft) | 67% | 9% | 77% | <0.001† |
| Etiology (% traumatic) | 62% | 45% | 46% | NS |
| Tunnel angle (median) | 24.5 | 17.0 | 21.5 | NS |
* The elongated ruptures had a significantly longer time between the primary surgery and re-injury than the mid-substance and distal ruptures, P = 0.002
†Cramer V = 0.543. The distal and mid-substance ruptures were more likely to be allografts reconstructions
