Problem: Total knee replacement (TKR) surgeries are increasing due to ageing populations. Current rehabilitation has a gap - patients do unsupervised exercises at home for 2-3 weeks between hospital discharge and outpatient appointments, leading to poor compliance and complications.
Current Issues: 25% of patients don't achieve meaningful functional improvement for 6+ months, and 20% still have significant limitations after 2 years.
Proposed Solution: Deploy a robot-aided device for intensive, self-paced home rehabilitation exercises to help patients return to near-normal function within 1 month.
Goals: Improve early functional recovery, increase exercise compliance, reduce costs, and enhance long-term quality of life for knee osteoarthritis patients.
