Three locations
A patellar fracture can disrupt the extensor mechanism. A tibial plateau fracture can depress the articular surface. A distal femur fracture affects the bone above the knee and can extend into the joint.
The initial assessment
A rapid assessment looks for skin, nerve, and vascular lesions. X-rays, sometimes supplemented by a CT scan, clarify the displacement and joint damage.
Treatment
Some stable, minimally displaced fractures require immobilization. Others require reduction and fixation. The decision also depends on the condition of the tissues and bone quality. Weight-bearing instructions are individualized.
Recovery
Follow-up monitors healing and mobility. Rehabilitation accompanies recovery; stiffness, poor healing, or secondary osteoarthritis remain possible. Pain alone is insufficient to determine when weight-bearing can resume.
Your questions.
When should I call emergency services?+
A deep wound, significant deformity, a cold or numb foot, or rapidly increasing pain after trauma requires urgent evaluation. Call 15 or 112; do not attempt to put the knee back in place.
