A patella fracture does not necessarily lead to disability, but depends on the severity of the patella fracture and the treatment method taken after the fracture occurs. In the case of a comminuted fracture, the joint surface is uneven, and the treatment is still conservative with external fixation in a cast, it is possible that the range of motion of the knee joint will be greatly restricted in the future, and walking and moving around more will cause significant pain in the knee joint, which is also a type of disability. However, these fractures have been treated with active treatment, surgical fixation, early functional rehabilitation and restoration of the joint surface flatness, and the above mentioned symptoms have been minimized. If the fracture dislocation itself is not serious or recovered well, it is basically similar to normal people and no special disability occurs.
