• Extensor mechanism is intact – Tx –
Protective
• A POP cylinder holding the knee straight
is worn for 4–6 weeks and during this
time quadriceps exercises are practiced
every day
...

• Occurs in field sports
...
Vascular injury -Popliteal artery

o High patella
Tibia & Fibula shaft fractures
• Tibia is more commonly fractured – subcut position
• often sustains an open fracture
• Mechanisms- Falls, sporting ,RTA
• Indirect injury is usually low-energy
with a spiral or long oblique
...
• Signs of an impending compartment syndrome
...
Internal Fixation
• Closed intramedullary nailing-tibial shaft fractures
• Plate fixation- For metaphyseal fractures deemed
unsuitable
for nailing

• the fibula must be restored to its full length
• the talus must sit squarely in the mortise, with the
talar and tibial articular surfaces parallel
