Hi, thanks for writing to HCM.
The method of management of tibial plateau fractures
depends on the its type (there are 6 types) but there is no mention about its type in description.
Generally, fractures with very minimal displacement can be treated by conservative management with either casts or braces and a non-weight bearing period for a minimum of 8-10 weeks depending upon the fracture pattern.
An exact "type" of the fracture is to be known to define the exact method of management.
Discuss with your treating doctor for any more issues.
Hope this information is helpful. Good day
