The study, published in the Journal of Bone and Joint Surgery, included 321 patients, according to a June 25 news release from the devicemaker.
Researchers found that 73.5% of patients who had surgery with the TOPS arthroplasty system reached composite clinical success at 24 months postoperatively compared to 25.5% in the fusion group. The arthroplasty group also outperformed the fusion group in most patient-reported outcome measures, and the fusion group had higher rates of symptomatic adjacent segment degeneration and revisions.
