Knee fracture after half a year before you can work, because most of the knee fractures are femoral condyle fracture, tibial plateau fracture or patella fracture, these fractures are intra-articular fracture, i.e., the fracture line passes through the joint surface. If you work too early, the patient will be left with joint pain in the future, so after the fracture fixation, healing should not be too early sense of heavy work, you can do lighter, for example, do not need to long distance weight-bearing walking, running, jumping, climbing slopes, climbing stairs work. If the weight is very large, walking distance is very long, need to carry things, carry things on the knee joint pressure work is best not to do, to do light physical labor.
