简要总结

The goal of this observational study is to learn about patients' recoveries after receiving total knee arthroplasty (TKA). The main questions it aims to answer are:

Does robotic-assisted TKA have improved perceived recovery when compared to conventional TKA? Does robotic-assisted TKA lead to improved functional recovery when compared to conventional TKA?

Researchers will compare if robotic-assisted versus conventional procedures lead to different recovery speeds.

Participants will answer questionnaires and undergo physical therapy testing before and at several timepoints after their procedure.

详细描述

The choice to perform robotic assisted vs manual total knee arthroplasties (TKA) depends on many factors, including but not limited to surgeon training, resource availability, and patient-specific considerations. Recent studies comparing patient outcomes after robotic-assisted and manual total knee arthroplasties have shown mixed results. These studies often focus on future complication rates, radiographic outcomes, or patient reported outcomes between manual and robotic-assisted TKA. Hence, there has been little focus on improvements in functional outcomes after TKA. Combining functional test results, patient reported outcomes, kinematic studies, and data from wearable devices will allow for a comprehensive timeline of recovery speed after either robotic-assisted or manual TKA.

The overall aim of this proposed study is to quantify functional and PROM at specific timepoints in patients after robotic-assisted or manual total knee arthroplasty (TKA).

The questions are:

Do robotic-assisted revision TKAs have improved functional and perceived recovery when compared to manual revision TKAs?
Do robotic-assisted primary TKAs have improved functional and perceived recovery when compared to manual primary TKAs?
Do robotic-assisted revision TKAs have similar functional and perceived recovery as robotic-assisted primary TKAs?

For questions 1 and 2, we hypothesize that robotic-assisted revision or primary TKAs will have improved recovery when compared to manual TKAs.
