Patient Characteristics and Pre-Operative Gait Speed as Useful Factors to Separate Recovery Curves Generated by a Smart Implant

Description

The presentation focuses on characterizing patient recovery following total joint arthroplasty through gait metrics captured by smart knee implants. The speaker discusses the importance of understanding how various patient characteristics—such as age, gender, BMI, and pre-operative activity—affect recovery trajectories. Using data from the Persona IQ smart implant, they highlight how multiple sensing modalities collect mobility information, which is essential for providing context to patients about their recovery progress. By analyzing these metrics, particularly focusing on pre-operative activity and patient gender, the research aims to deliver meaningful feedback to patients, allowing them to understand their recovery compared to similar patients.



Key insights include:

- Importance of smartphone-based care management platforms in tracking patients' pre-operative and post-operative data.

- Analysis of recovery curves to determine significant patient attributes that influence recovery.

- Differentiation between activity-oriented metrics and range of motion metrics, with pre-operative activity being impactful for the former and gender for the latter.

- Future steps aim to create a holistic view of recovery, encompassing various metrics beyond movement, including pain, to improve patient feedback.
