Summary of preoperative equations to predict JLCA change or soft tissue correction
| Author | Year | Prediction model | Equation | R2 |
|---|---|---|---|---|
| Lee et al. | 2019 | JLCA change |
−1.7 + (0.6 × latent medial laxity) + (0.2 × correction angle) |
0.49 |
| Takagawa et al. | 2019 | postoperative soft tissue correction | 0.691 × JLCA −0.411 × valgus JLCA − 0.399 | 0.37 |
| So et al. | 2019 | postoperative soft tissue correction | planned amount of correction angle – ΔJLCA (ΔJLCA = supine – standing) | 0.47 |
| Kim et al. | 2017 | predictive additional overcorrection | −1.149 + 0.803 x JLCA + 0.176 x LDFA | 0.37 |
ΔJLCA JLCA changes between two conditions, LDFA lateral distal femoral angle
