Overview
- What this talk covers
The Patella and Why It Matters
Anatomy that drives every treatment choice
- The patella in one slide
- Its joint surface is unusual
- Patellar shape and femoral contact
- The extensor mechanism: how the knee straightens
- Extensor mechanism and patellar lever
- Why the patella earns its keep
- The Q angle and sideways pull
- What keeps the patella on track
- Q angle and the femoral groove
- Blood supply and a nerve to protect
- Blood supply and saphenous nerve
How Patellar Fractures Happen
Mechanism of injury and classification
- Direct versus indirect force
- Combined mechanism and what displacement tells you
- How we classify patellar fractures
- Patterns of patellar fracture
Assessing the Injured Knee
Examination and imaging
- At the bedside
- Is the extensor mechanism intact?
- Reading the X-rays: AP view
- Reading the X-rays: lateral view
- Lateral radiograph and patellar height
- The axial (Merchant) view
- Axial (Merchant) view of the patella
When and How to Operate
Indications and the tension-band principle

- Three treatment routes
Open Reduction and Fixation
Step by step, pattern by pattern
