(1)OsteoArthritis and Cartilage (2006) 14: Placement of intra-articular injection verified by the backflow technique.

When needle tip position is confirmed by aspiration, treatment efficacy significantly improves

Successful treatment

  • Assists in verifying correct position through aspiration
  • Reduces exposure of hub to air and handling
  • Enables practitioners to be fully engaged and focused on procedures
  • Provides improved workflow and equipment accountability

Failed treatment

20% of injections miss the correct site, failing to deliver medication and failing to provide pain relief.
