- The patellar is a sesamoid bone.
- The proximal part of the patellar allow attachment of the quadriceps tendon while the distal pole allows the infrapatellar tendon to attach it to the infrapatellar tuberosity,
If the retinaculum is intact then there is usually minimal fracture fragment displacement.
An alternative material to consider to the traditional stainless steel tension band wiring include braided polyester suture (No 5 Ti-cron, No 5 Ethibond) thread with good results (McGreal et al, Patel et al, Lee et al) or Fibrewire (Lee BJ et al) as there are fewer complications relating to stainless steel wire.
Knee range of motion (ROM) brace allows the degree of knee ROM to be set. Brace or apply plaster of Paris for 4 weeks for patellar fractures with intact extensor mechanism or for stable post ORIF fracture set brace 0° -30°.
Foot ROM, pre and/or post surgery allowing lower limb circulation
