An interventional study of Mobility Tool in Total Knee Arthroplasty, sponsored by Stanford University. Recruiting at 1 site in United States. Open to participants aged 18 Years to 99 Years. Per ClinicalTrials.gov, last updated 2026-03-17.
Sponsored by Stanford University · Not applicable, Interventional, and Supportive care
Maneuverability is currently under appreciated by patients who are seeking mobility. This pilot study is examining how patients maneuverability and mobility will change with this novel mobility tool.
Individuals living with challenges that affect their mobility may lead to loss of independence, loss of activity and engagement with life. We are seeking individuals who are having a Total Knee Replacement and are seeking increased mobility using the Alinker, which is a non-motorized walking bike without pedals.
Each participant will receive the Alinker prior to surgery, and will be encouraged to use it as much as possible before surgery and during the 3-month post-operative period.
Stanford University is the lead sponsor of 2,117 studies on the registry; 425 are open to participants now.
Of its 259 completed or terminated interventional studies of FDA-regulated products, 197 (76%) have results posted.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
19 patients get an A-linker 1-3 months before surgery (knee arthroplasty)
Device: Mobility Tool
An A-Linker device will be given to 12 patients 3 months before their total knee arthroplasty
Mobility after surgery
Mobility will be assessed by using a bicycle odometer to track usage and mobility. The odometer will be checked 2 weeks, 6 weeks, and 3 months after surgery during a post-op clinical exam.
Time frame: 6 months
Determining intensity of pain
We plan to use VAS pain scale as measurement scale ( range; 0-10, higher scores correspond to greater pain
Time frame: 6 months
Change in knee society score
To assess the effectiveness of the device by calculating Initial knee society score (KSS) and Knee society score at 2 weeks, 3 months and 2 years after surgery. The scale ranges from 0-100 with grading as Score 80-100 - Excellent Score 70-79 - Good Score 60-69 - Fair Score below 60 - Poor
Time frame: 6 months
surgery cancellation
To determine if surgery was cancelled as a result of effectiveness of device
Time frame: 6 months
Use of gait aide
To assess the effectiveness of the device by examining Gait Aide use at discharge, 2 weeks, 3 months and 2 years after surgery. This is done to examine performance . The gait aide use provident ranges as Nothing \> Cane \> crutch \> walker
Time frame: 6 months
Time with Device
Determining compliance of device usage
Time frame: 6 months
