Overview
In this collaboration, Sentinel's objective gait measurements documented recovery trajectories for patients treated with Kinomatic's surgical planning technology, with measured recovery milestones reached notably faster in the tracked cohort.
When surgical innovators introduce new techniques, demonstrating better outcomes requires objective, longitudinal measurement — precisely what traditional episodic follow-up struggles to provide. This case study covers a collaboration between Kinomatic, a surgical planning technology company, and Sentinel.
Patients undergoing joint replacement with Kinomatic's personalized surgical planning were monitored through recovery using Sentinel's smartphone-based gait assessments, producing dense recovery trajectories: walking speed, symmetry, and variability measured regularly from the early post-operative weeks onward.
In the tracked cohort, patients reached measured recovery milestones — such as returning to age-typical walking speed ranges — on average around 40% faster than published typical recovery timelines for conventional approaches. The dense measurement also revealed the shape of recovery curves, showing where progress accelerated and plateaued.
Cohort comparisons against published timelines carry inherent limitations — patient selection, care environments, and measurement methods all differ — and these findings are not claims of guaranteed results for any patient. The methodological point stands on its own: regular objective measurement made a new technology's recovery story visible in a way episodic follow-up could not.
Key Takeaways
- Dense gait measurement documented full recovery trajectories
- Tracked cohort reached milestones ~40% faster than published typical timelines
- Comparison against published timelines carries inherent limitations
- Objective measurement made innovation's impact visible
