Fixation of the patella with a Kirschner pin tension band generally does not affect knee flexion, and in some cases affecting knee flexion may be related to inadequate functional exercise or pain.
When a patella fracture is severe enough to require surgery for internal fixation, the patella is usually immobilized with a Kirschner pin tension band, thus helping the fractured patella to heal. Since the Kirschner pin is passed inside the patella and the tension band surrounds the patella, it does not affect the patellofemoral joint movement. Therefore, knee flexion and extension are generally not affected.
For patellar fracture Kirschner’s needle tension band internal fixation after the knee bending limitations, most of the cases are related to the lack of postoperative functional exercise of the knee, followed by the early postoperative period of the knee in the bending will be due to the pain of bending insufficient situation.
Please consult your surgeon if you have any discomfort after Kirschner’s Tension Band Surgery.
