Patella Fractures — Tension Band Wiring
Indications: displaced transverse fractures with intact extensor. Principle: converts tensile quadriceps force into compression at fracture site. Technique: 2 parallel K-wires + figure-of-8 SS wire. Avoid in comminution → partial patellectomy/plate fixation. Complications: hardware prominence, migration, stiffness.
