Interventions

The robot performs an obstacle-straddling motion from a stationary standing position and records it on video.

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Patients with osteoarthritis of the knee, radiologically diagnosed as grade 3 and/or 4 according to Kellgren-Lawrence criteria, and scheduled to undergo TKA. The participants must have obtained written consent to participate in this study.

Exclusion criteria

Exclusion criteria: Those with uncontrolled systemic diseases or pre-existing neurological or other orthopedic conditions other than osteoarthritis of the knee that affect the ability to walk.
