A patient with a total knee arthroplasty should be what by discharge?

• A. Non-weight bearing
• B. Partial weight bearing
• C. Toe-touch weight bearing
• D. Fully weight bearing

Answer: (D)

After a total knee arthroplasty, the goal is to promote early mobility with weight bearing as tolerated. With modern cemented implants, the fixation provides enough stability to allow full weight bearing as tolerated by discharge, usually with a walker or crutches initially and progression to unassisted walking as therapy advances. This approach helps reduce risks such as blood clots, lung complications, and muscle weakness, while supporting healing and range of motion. Restrictions like non-weight bearing or only toe-touch are not typically used in uncomplicated cases, unless the surgeon notes issues with fixation or healing.
