Physical examination
• Vital sign T 36.8 c, BP 130/70 mmHg, P 88/min,
RR 18/min, O2sat 98%
• General appearance : A Thai girl, crying
• HEENT : not pale conjunctiva, anicteric sclera
• Heart : no active precordium, no heaving, no
thrill, normal S1S2, no murmur
• Lung : clear both lung
• Abdomen : soft, not tender, no guarding
• Extremities : cut wound deep to bone at anterior
left knee , limit ROM due to pain
Differential diagnosis & Investigation
Diagnosis
Open fracture
Left patella
Fracture of Patella
Investigation
◦ Film Knee AP and Lateral
◦ Film Knee Merchant’s view
Classification
Modified Weissman
Treatment
Non-operative management
◦ knee immobilized in extension
(brace or cylinder cast) and full weight bearing 6-8 week
◦ indications
◦ intact extensor mechanism (patient able to perform straight leg
raise)
◦ Non-displaced or minimally displaced fractures
(displace or step off < 3 mm.)
Operative management
ORIF with tension band construct
◦ indications
◦ preserve patella whenever possible
◦ extensor mechanism failure (unable to perform straight leg raise)
◦ open fractures
◦ fracture articular displacement >2mm
◦ displaced patella fracture >3mm
◦ patella sleeve fractures in children
partial patellectomy
◦ indications
◦ comminuted superior or inferior pole fracture measuring <50% patellar height
ONLY if ORIF is not possible
total patellectomy
◦ indications
◦ reserved for severe and extensive comminution not amenable to salvage
Treatment
Complication
◦ Late osteoarthritic change of patellofemoral joint
◦ Painful Retained Hardware
Management
◦ In this patient
◦ Set OR for Debridement and ORIF
