Knee Joint

3.3K
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...

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Area of Science:

  • Orthopedics
  • Biomedical Engineering
  • Musculoskeletal Research

Background:

  • Knee joint noise is a prevalent symptom prompting outpatient visits.
  • A lack of comprehensive review articles on knee noise exists despite its frequency.
  • Differentiating physiological from pathological knee noise is crucial for patient management.

Purpose of the Study:

  • To review knee noise characteristics based on sound nature and onset.
  • To identify factors differentiating physiological from pathological knee noises.
  • To describe the causes and management strategies for knee noise.

Main Methods:

  • Literature review of existing studies on knee joint noise.
  • Analysis of noise characteristics, pathophysiology, and differentiation factors.
  • Synthesis of information on causes and management of physiological and pathological knee noises.

Main Results:

  • Physiological knee noise is distinct from pathological noise, requiring careful differentiation.
  • Postoperative noise perception can be influenced by pre-existing sounds and patient expectations.
  • Proper surgical techniques and patient education can mitigate dissatisfaction related to knee noise.

Conclusions:

  • Accurate characterization and differentiation of knee noise are essential for effective patient guidance.
  • Managing patient expectations and providing information on physiological noise can reduce dissatisfaction.
  • In total knee arthroplasty, utilizing modern prostheses and precise surgical techniques can minimize patellar crepitus and clunk.
