Knee Joint

1.7K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Summary
This summary is machine-generated.

Patients undergoing intra-articular knee injections (IAKI) experience significantly less pain than anticipated. Educating patients on expected pain levels may improve procedural compliance.

Area of Science:

  • Orthopedics
  • Pain Management
  • Patient Experience

Background:

  • Intra-articular knee injections (IAKI) are common for diagnosis and therapy.
  • IAKI can cause patient anxiety and fear.
  • The difference between expected and actual pain during IAKI is not well-studied.

Purpose of the Study:

  • To quantify the difference between anticipated and experienced pain during IAKI.
  • To explore factors influencing fear and anxiety related to IAKI.

Main Methods:

  • A cohort of 50 patients undergoing IAKI was studied.
  • Patients recorded anticipated pain, experienced pain (Visual Analogue Scale - VAS), anxiety index, and fear factors.
  • Injections were performed by an orthopedic specialist in an outpatient setting.

Main Results:

  • A significant difference was found between expected pain (mean VAS 6.19) and experienced pain (mean VAS 2.07, P < 0.001).
  • This pain difference was significant in both males and females.
  • The delta between expected and experienced pain varied significantly between sexes.

Conclusions:

  • Patients consistently underestimate the pain associated with IAKI.
  • Educating patients about realistic pain expectations can reduce anxiety.
  • Providing quantified pain information may enhance patient compliance with IAKI procedures.
