ALIGN3D Lapiplasty® Clinical Study

Why is this study being done?

“With thousands of surgical cases performed, the Lapiplasty® Procedure is being adopted rapidly across the United States as surgeons recognize the benefits of performing a 3-dimensional correction that also addresses the root cause of the bunion problem,” said John T. Treace, CEO of Treace Medical. “We are excited to have initiated this important study, which we believe will further differentiate the Lapiplasty® Procedure as the standard of care for bunion sufferers.”

“Previously presented clinical data on the Lapiplasty® Procedure with early return to weight-bearing demonstrated a 3.2 percent recurrence rate at 13.5 months.1 The ALIGN3D study will determine recurrence at 24 months and produce a robust dataset that will provide additional insight into the Lapiplasty® Procedure across a number of endpoints,” said Dane Wukich, MD., Professor and Chairman, Department of Orthopedic Surgery at the UT Southwestern Medical Center and the study’s lead principal investigator.


  • Study Design: This study is a prospective, multicenter, unblinded study and will enroll up to 200 patients, aged 14 to 58 years, at up to 15 clinical sites in the United States.
  • Objectives: The post-market study is designed to evaluate the ability of the Lapiplasty® Procedure to consistently and reliably correct all three dimensions of the bunion deformity and maintain the correction following accelerated return to weight-bearing. The study’s primary endpoint is radiographic recurrence of the bunion deformity at 24 months follow up. Secondary endpoints include change in three-dimensional radiographic alignment; clinical radiographic healing; time to start of weight-bearing in a boot and in shoes; pain; quality of life; and range of motion of the big toe joint. Identifier: NCT03740282
