Summary of "A New Total Knee Arthroplasty Design Has Significantly Better Early Implant Survivorship than a Previous Gold-Standard Design-A Retrospective Analysis of 1,000 Cases."

This study examined whether a new total knee arthroplasty (TKA) prosthesis improved implant survivorship and reoperation rates compared with a gold-standard, established TKA. A retrospective analysis of the first 500 consecutive new TKAs was compared with a consecutive series of the last 500 currently available TKAs performed by a single senior surgeon in one center. The primary outcome measure was revision of the femoral, tibial, or patellar component. A secondary outcome was reoperation for any reason. The new-TKA group had a significantly reduced revision rate at up to 5 years follow-up ( = 0.02). Reoperation rates for any reason were similar ( = 0.3). The new TKA design has a significantly better early revision rate compared with a currently available gold-standard TKA. This is the largest study of 1,000 cases comparing a new TKA design with a currently available design with excellent midterm results. It demonstrates very favorable early clinical results for the new TKA design, providing reassurance for patients, surgeons, and regulatory bodies.
