Patellar comminuted fractures, as long as treated promptly and correctly, and if the surgery poses no issues, generally heal in about six months, thereby not causing any significant impact. Thus, there's no need to worry about limping. Limping usually means that when walking, one leg appears longer than the other. Under what circumstances can limping occur? If the difference in leg length is within one centimeter, it's imperceptible and won't have any effect. If the difference exceeds two centimeters, then there is a noticeable tilt in the lower limbs, and only then can limping be observed during walking; however, even if limping occurs, it is not severe. It just means that while walking, there is a tilt towards the shorter side. After treatment, patellar comminuted fractures have a complete chance of healing and once healed properly, it's almost like before the injury. Even in severe cases where the fracture is critically fragmented and requires removal, even without patellar replacement, by reinforcing the patellar tendon, it typically does not result in limping. It only impacts the strength in knee extension, possibly creating a mild impediment compared to the other side, and might make walking appear slightly abnormal, but it definitely does not lead to limping. Hence, patellar comminuted fractures do not result in limping.
