Official title
Continuous Monitoring Using a Smart Implantable Device (Persona IQ®) to Compare Medial Parapatellar vs. Subvastus Approaches in Early Post-Operative Total Knee Arthroplasty Recovery
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a single-institution, prospective, randomized study comparing the medial parapatellar and subvastus approaches in primary total knee arthroplasty using continuous, implant-based gait monitoring. Patients receiving a Zimmer Persona IQ smart implant will be followed preoperatively and through the first 30 days post-operatively, with extended follow-up to 6 months. Preoperative activity is captured using iPhone Health step-count data, while post-operative recovery is assessed using continuous tibial implant data, including step count, range of motion, cadence, walking speed, stride length, and distance. These objective metrics are correlated with PROMs. The primary outcome is daily step count. Secondary outcomes include early functional milestones, pain, and patient-reported functional scores. This study is designed to characterize early recovery trajectories and determine whether meaningful differences exist between surgical approaches.
