| Kanthila Mahesha et al. 2017 | May 2012 to January 2014 | Retrospective Study | 100 | Mean age was 40.29 years | 67 Males & 33 Females | Excellent outcome was noted in 90 patients, good outcome in six patients, fair result in 2 patients and poor result in 2 patients. The mean VAS reduced drastically from 8.2 preoperatively to 1.8 postoperatively (P < 0.001). ODI also showed marked improvement from a preoperative 54% to a postoperative 8% (P < 0.001). |
| Yu-tong Gu, Zhan Cui, Hong-Wei Shao et al. 2017 | January 2012 to June 2013. | Retrospective Study | 209 cases | Average age of male was 46.4 ± 14.9 years and female was 46.8 ± 11.1 years | 116 Male and 93 Female | The VAS score of leg pain significantly dropped from 9 (6 - 10) before operation to 1 (0 - 3) (P < 0.001) immediately after the operation and to 0 (0 - 3) (P < 0.001) 2 years after operation. At 2-year follow-up, 95.7% (200/209) of the patients showed excellent or good outcomes, 2.9% (6/209) fair and 1.4% (3/209) poor. |
| Z Gao, S Yin, T Xiang et al. 2017 | March 2015 to September 2015 | Retrospective Study | 32 | - | Male and Female | The patients had VAS score of low back and leg pain decreased from preoperative (6.75 ± 1.29) and (8.69 ± 1.51) to (2.35 ± 0.49) and (1.45 ± 0.36) in 6 months after surgery. Compared with preoperative score, the postoperative VAS score was statistically significant (P < 0.05). MacNab was as follows: excellent in 25 cases; good in 4 cases; common in 3 cases. The excellent and good rate was 90.63%. |
