Relationship between joint gap tilt and clinical results or preoperative FTA*
| Variables | Lateral tight (n = 17) | Well-balanced (n = 17) | Medial tight (n = 29) | p value |
|---|---|---|---|---|
| Tilting angle (°) | −4.0 ± 2.7 (−9.3 to −1.1) | 0.0 ± 0.7 (−1.0 to 1.0) | 3.6 ± 2.1 (1.3 to 9.0) | < 0.001 (ANOVA) |
| Extension (°) | −1 ± 2 | −2 ± 3 | −1 ± 2 | 0.575 (ANOVA) |
| Flexion (°) | 125 ± 13 | 124 ± 21 | 124 ± 20 | 0.987 (ANOVA) |
| Knee Society knee score | 95 ± 5 | 91 ± 5 | 93 ± 7 | 0.126 (ANOVA) |
| Knee Society function score | 66 ± 13 | 71 ± 22 | 62 ± 26 | 0.343 (ANOVA) |
| Instability (+/−) | 7/10 | 10/7 | 11/18 | 0.369 (chi square) |
| Preoperative FTA (°) | 188 ± 6 (179–203) | 183 ± 8 (162–195) | 185 ± 9 (165–203) | 0.254 (ANOVA) |
