ACFAS25: Treace Lapiplasty, Adductoplasty Data Shows Positive Outcomes

Treace Medical Concepts presented updated interim data from its ALIGN3D and Mini3D Lapiplasty clinical studies, as well as the first presentation of the MTA3D Adductoplasty study, at this year’s American College of Foot and Ankle Surgeons (ACFAS) annual meeting.

“This builds on our commitment to support our flagship Lapiplasty and Adductoplasty procedures with clinical evidence and notably marks the first meeting where all three of our prospective, multicenter studies are presented, including our ALIGN3D, Mini3D, and MTA3D studies, demonstrating positive clinical outcomes and further differentiating these procedures with surgeons and patients,” said John T. Treace, founder, CEO, and board member of Treace.

ALIGN3D Lapiplasty study

The presentation was entitled “Four-Year Analysis of a Five-Year Prospective Multicenter Study Assessing Radiographic Recurrence and Patient Outcomes Following Triplanar Tarsometatarsal Arthrodesis with Early Weightbearing.” It featured Treace’s interim data and analysis from the five-year ALIGN3D study of 135 of 173 patients treated within the last four years of follow-up.

There was an early return to weight bearing at an average 8.4 days, with low radiographic recurrence rates and continued, significant improvement in pain and patient-reported outcome scores.

Mini3D Lapiplasty Mini-Incision study

This Treace presentation was called “Prospective Multicenter Study Assessing Radiographic and Patient Outcomes Following an Instrumented Mini-Open Triplanar Tarsometatarsal Arthrodesis with Early Weightbearing.” It featured results of the Mini3D clinical study of the Lapiplasty Mini-Incision procedure (median incision length: 3.5cm) and included interim analysis of 75 of 105 patients treated with at least one year follow-up.

Data showed early return to protected weightbearing at an average of 7.9 days, with low radiographic recurrence rates. There were also significant improvements in pain and patient-reported scores.

MTA3D Adductoplasty study

This presentation was named “Interim 1-Year Analysis of a Prospective Multicenter Study Assessing Radiographic and Patient-Reported Outcomes Following Combined Metatarsus Adductus and Hallux Valgus Correction through 3rd, 2nd, and 1st Tarsometatarsal Arthrodesis with Early Weightbearing.” It featured interim data from the five-year MTA3D clinical study of the patients undergoing both the Adductoplasty and Lapiplasty procedures and included interim analysis of 18 of 38 patients treated with at least one year follow-up.

Data showed early return to protected weightbearing at an average of 7.5 days. There was clinically significant improvement relative to baseline in radiographic measures of both midfoot (metatarsus adductus) and 3D bunion deformity correction at 12 months, and Clinically significant reduction in pain and patient-reported scores (MOxFQ and PROMIS) at 12 months
