Procedure described for doing one leukocyte rich and one leukocyte poor injection.

Equipment

  • Syringes
    • 60mL syringe for the blood
    • 10mL syringe for the local anaesthetic
    • 10mL syringe for the leukocyte poor PRP
    • 10mL syringe for the leukocyte rich PRP
  • Needles
    • butterfly set for taking blood
    • drawing up needle
    • 25g needle for the local anaesthetic
    • Needle for the PRP injection e.g. 22g 70mm spinal needle for the hip joint.
  • 3 x ACDA tubes for the anticoagulant
  • PRP kit
    • One cartridge for the blood (e.g. omni PRP which is ~6x concentration, or regen which is ~2x concentration)
    • Another cartridge as a counterbalance, measured to weigh the same, filled with water.
  • Centrifuge
  • Sterile ultrasound jelly
  • Ultrasound machine
  • PRP benchtop processing station.

Preparation

  • Extract ~2.5mL of ACDA into the 60mL syringe
  • Draw up 55mL of blood into the 60mL syringe
  • Place the drawing up syringe onto the syringe, open the top of the cartridge, and then transfer the mixed blood/ACDA solution. Close the top
  • Place the cartridge into the centrifuge, along with an equal counterweight cartridge.
  • Spin at 3350rpm for 7 minutes
  • Remove the cartridge, it should be separated into red cells at the bottom, leukocytes in the middle, and plasma at the top
  • Place the cartridge into the PRP benchtop processing station, facing up
  • Use the dial on the station to control the plunger
  • Remove and discard the top half of the plasma
  • The remaining plasma is leukocyte poor at the top, and leukocyte rich at the bottom. The very bottom of the plasma has the leukocytes.
  • Transfer the top remaining half (leukocyte poor) into a 10mL syringe
  • Transfer the bottom remaining half, including some of the leukocytes into another 10mL syringe.

Procedure

Joint
  • Infiltrate the skin and capsule with local anaesthetic but not the joint space
  • Inject into the joint space or joint structure with the leukocyte poor solution
Tendon
  • Inject around the tendon with the leukocyte rich structure

Aftercare

Leukocyte rich PRP can cause a pain flare for a few days. Advise to wait for minimum 4 weeks before assessing efficacy.
