Learning curve with a new primary total knee arthroplasty implant: a multicenter perspective with more than 2000 patients.

ABSTRACT:

Background

This study provides an example for evaluating learning curve when introducing a new knee system.

Methods

Thirty-five investigators across 22 sites prospectively implanted 843 subjects with currently available products (group A). Seventy-seven investigators across 48 sites prospectively implanted 2330 subjects with the ATTUNE Knee System; in which the first 10 subjects for each surgeon were the learning curve cases (group B, N = 611), and the later subjects were designated as group C (N = 1719). Surgical time, rates of intraoperative and early postoperative complications, and patient-reported outcome measures (PROMs) at a minimum of 1 year were compared.

Results

Mean (standard deviation) surgical time was 72.0 (21.6) minutes for group A, 83.0 (24.2) for grou
