Group E (n = 84 patients) |
P value | |
|---|---|---|---|
| EG | 3.9 ± 2.1 | 7.4 ± 1.7 | < 0.001* |
| FG | 7.6 ± 1.5 | 7.6 ± 1.9 | n.s. |
| FG – EG | 3.7 ± 1.7 | 0.2 ± 0.4 | < 0.001* |
| EG following PMVC | 7.6 ± 1.6 | ||
| FG following PMVC | 8.1 ± 1.5 | ||
| FG – EG following PMVC | 0.4 ± 0.6 | ||
| Additional cut (4 mm/3 mm) | 12 / 7 | 18 / 66 | n.s.a |
Data are displayed as means ± standard deviation. Statistical differences were analyzed using the Mann–Whitney U test, except for Fisher’s exact tests (a). EG extension gap, FG flexion gap, PMVC posteromedial vertical capsulotomy, n.s not significant; (*) statistically significant (P < 0.05).
