Summary of JLCA influence on osteotomy correction
| Author | Year | Soft tissue correction (Mean ± SD) | What is error Correction? | Identified risks factors for correction errors |
|---|---|---|---|---|
| Kubota et al. | 2020 | 4.4 ± 2.9 | Difference between the correction angle during surgery and the radiological correction angle |
- Pre MPTA, - JLCA is not associated with ovecorrection |
| Kumagai et al. | 2020 | – | ΔJLCA > 2° | - Post JLCA on the day of surgery |
| Goshima et al. | 2019 | – | Patients overcorrected group if MPTA > 95° | - Larger pre JLCA |
| Tsuji et al. | 2019 | 2.0 ± 1.5° | Navigation correction loss > 1.5° | - Higher standing JLCA |
| Lee et al. | 2019 | 2.6 ± 2.2° | ΔHKA angle in standing long-bone radiographs – ΔHKA angle in navigation |
- JLCA in varus stress - Latent medial laxity |
| Takagawa et al. | 2019 | 3.2° |
ΔHKA angle – ΔMPTA defined as the soft tissue correction |
- Pre JLCA - JLCA in valgus stress |
| So et al. | 2019 | 2.0 ± 2.4° | the difference between the change in MA on standing whole-leg radiograph and the coronal correction by navigation > 3° |
- Larger ΔJLCA (supine – standing) - Pre varus deformity - Pre JLCA - JLCA in varus stress |
| Park et al. | 2019 | 5.8 ± 7.4% |
Overcorrection if WBL ratio > 10% of the target WBL |
- Pre JLCA - Valgus stress angle - ΔJLCA (pre – post) |
| Ogawa et al. | 2016 | 3.4 ± 2.5° |
ΔHKA angle – ΔMPTA defined as the soft tissue correction |
- JLCA under varus stess - ΔJLCA (pre – post) |
| Lee et al. | 2015 | – | WBL ratios < 57 and > 67% were classified as under- or over-corrections |
- Pre JLCA - ΔJLCA (pre – post) |
Pre preoperative, Post postoperative, ΔJLCA JLCA changes between two conditions, ΔHKA angle Global correction or postoperative, HKA angle preoperative HKA angle, ΔMPTA Bony correction or preoperative, MPTA postoperative MPTA, WBL weight bearing lines
