The median age at surgery was 43.0\u200a\u00b1\u200a9.0 years. Preoperative diagnosis included degenerative disc disease in 118 (96.7%) and internal disc disruption in 4 (3.3%). Surgery was performed at L5\u2013S1 in 96 (77.9%) patients and at L4\u2013L5 in 27 (22.1%). Statistically significant clinical improvements from baseline were observed on VAS (back and leg), ODI, SF-36 PCS, SF-36 MCS, and RMDQ 3 months onward. Back VAS scores decreased from 78.2\u200a\u00b1\u200a21.3 preoperatively to 21.9\u200a\u00b1\u200a27.8 by final follow-up. ODI scores decreased from 51.1\u200a\u00b1\u200a17.3 to 16.2\u200a\u00b1\u200a17.9 at last follow-up. The RMDQ scores also decreased from 16.7\u200a\u00b1\u200a4.7 to 4.2\u200a\u00b1\u200a5.8. SF-36 PCS and MCS increased from 25.7\u200a\u00b1\u200a11.0 to 46.4\u200a\u00b1\u200a10.3 for PCS and from 35.5\u200a\u00b1\u200a17.4 to 51.6\u200a\u00b1\u200a10.8 for MCS. Patient satisfaction surveys indicated that 90.56% patients rated their satisfaction with the surgery as \u201cexcellent\u201d or \u201cgood\u201d at 2 years. Range of motion averaged 8.6\u200a\u00b1\u200a3.5 (median\u200a=\u200a8.0\u00b0) at the last follow-up time point.<\/jats:p>\n <\/jats:sec>\n \n Conclusion.<\/jats:title>\n Outcomes verify the clinical efficacy of total disc replacement for treatment of discogenic back pain with or without radiculopathy.
