Manipulation under Anesthesia Following TKA with Persona IQ: A Case Series.

INTRODUCTION: Although surgical devices and techniques continue to improve, regular post-operative monitoring of patients is required to ensure the best outcomes. New technological advances have allowed physicians to monitor the daily recovery of total knee arthroplasty (TKA) patients. This report is the first to describe the utilization of an implantable gait monitoring device and its capacity to detect poor early post-operative outcomes.

CASE REPORT: Two patients, a 78-year-old male and a 34-year-old female, were assessed post-TKA utilizing remote gait kinematics and clinical evaluations and determined to need manipulation under anesthesia due to severely limited range of motion. One patient, a 51-year-old female, with good clinical outcomes, was used for comparison.

CONCLUSION: Remote monitoring may provide an earlier indication than clinical evaluations in identification of TKA patients at risk of poor outcomes and may who need intervention. The use of remote kinematic gait data in earlier identification of patients at risk has the potential to help improve outcomes for the broader population of TKA patients.
