Long-term clinical and radiographic results of a pegged tibial baseplate in primary total knee arthroplasty.
Tibial baseplates of total knee arthroplasty components use stems, fins, and pegs to augment fixation. A pegged design without a stem offers flexibility in tray orientation and ease of revision. These advantages would not be important if stemless designs resulted in a higher rate of aseptic loosening. This article presents an average 10.5-year follow-up of a system offering a pegged tibial baseplate. Good or excellent results in 91% of patients are cited with a revision rate for aseptic loosening of 1%. A pegged design may offer advantages without a higher rate of complications when compared with stemmed implants.
