Cadaveric biomechanical study using electronic pressure sensors to quantify and compare patellofemoral contact forces and pressures generated during suprapatellar versus infrapatellar intramedullary tibial nailing across 17 fresh-frozen cadaveric specimens.
When considering a suprapatellar entry portal for tibial nailing — particularly for proximal fractures or cases where knee flexion is limited — this data supports its biomechanical safety from a cartilage-pressure standpoint, as long as a protective cannula is used.
Keep in mind that the IP pressures here were likely underestimates, so the true pressure differential between techniques in real patients may be smaller than these cadaveric numbers suggest.
