Patient Perceptions of Smart Knee Implant Technology Prior to Total Knee Arthroplasty: A Cross-Sectional Survey of Attitudes Towards the Zimmer Biomet Persona Iq

Background Smart implant technologies capable of continuously collecting objective recovery data have recently been introduced in total knee arthroplasty (TKA). However, patient perceptions and willingness to adopt implant-integrated monitoring remain poorly characterized. This study evaluated attitudes toward a commercially available smart knee implant among patients scheduled for primary TKA. Methods In this cross-sectional survey study, patients with knee osteoarthritis scheduled for primary TKA at a single academic center were shown a standardized 3-minute educational video describing the Zimmer Biomet Persona IQ smart knee implant. Immediately following, patients completed a survey assessing willingness to receive a smart implant, perceived benefits, concerns, and preference compared with a removable wearable monitoring device. Descriptive statistics were used to summarize responses. Results A total of 179 patients completed the survey (mean age 66.4 ± 9.3 years; 56.4% female). Of respondents, 71.5% indicated willingness to receive a smart knee implant. The most common concerns were potential differences in performance compared with standard implants (51.7%), higher cost to the patient (38.2%), and higher cost to insurance (34.1%). The most frequently perceived benefit was enhanced information for both patient and surgeon regarding recovery (83.1%). When comparing monitoring modalities, 44.8% preferred a smart implant, 38.7% preferred a removable wearable device, and 16.6% preferred neither. Conclusions After standardized education regarding a commercially available smart knee implant, most patients scheduled for TKA expressed willingness to adopt implant-integrated monitoring. While patients identified perceived benefits, concerns regarding performance and cost remain. These findings may inform shared decision-making as smart implant technologies are incorporated into arthroplasty practice.
