Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance01:14

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

694
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Hemodialysis II: Procedure and Complications

937
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Personality Disorders: Narcissistic and Avoidant

840
Narcissistic and avoidant personality traits represent two contrasting patterns of behavior that significantly influence social interactions and self-perception. While individuals with narcissistic disorder seek admiration and validation, individuals with avoidant personality disorder withdraw due to fear of judgment.
Characteristics of Narcissistic Personality Disorder
Narcissistic individuals exhibit an inflated sense of self-importance and an excessive need for admiration. They are often...

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanical Engineering

Background:

  • Recurrent lateral patellar instability is often linked to specific anatomical abnormalities.
  • These abnormalities include patella alta, increased tibial tubercle-to-trochlear groove distance, trochlear dysplasia, and malalignment.

Purpose of the Study:

  • To discuss potential complications of medial patellofemoral ligament (MPFL) reconstruction.
  • To review current literature focusing on preventing these complications.

Main Methods:

  • Review of cadaveric studies characterizing MPFL anatomy and associated abnormalities.
  • Evaluation of recent studies on clinical outcomes of combined MPFL reconstruction and concomitant pathology treatment.

Main Results:

  • Anatomical abnormalities like patella alta and trochlear dysplasia contribute to instability.
  • Addressing concomitant pathology during MPFL reconstruction is crucial for preventing recurrence.
  • Key surgical concepts include proper workup, addressing morphology, anatomical fixation, and graft management.

Conclusions:

  • MPFL reconstruction requires careful consideration of patient-specific anatomy and concomitant pathologies.
  • Adherence to established surgical principles can minimize complications and improve outcomes.
  • Further consensus is needed on specific aspects of MPFL reconstruction techniques.
