Surgeon Learning Curve With Selection of New Total Knee Arthroplasty Implants and Risk of Revision: A Registry-Based Cohort Study.

ABSTRACT:

Introduction

Prior studies have reported learning curves as surgeons adopt new technology/techniques. The authors sought to evaluate revision risk following primary total knee arthroplasty (TKA) to assess whether a learning curve was observed as surgeons transitioned to 1) a new implant from the same manufacturer and 2) a new implant from a new manufacturer.

Methods

Patients ≥ 18 years of age who underwent primary fixed bearing, posterior stabilized, fully cemented TKA with patella resurfacing were identified using a US integrated health care system's total joint replacement registry (2009-2023). The exposure groups were categorized in these groups: baseline implant (reference), first 50 TKA with new implant (≤ 50), second 50 (51-100), third 50 (101-150), and the remainder (
