Knee Joint01:23

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...

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.6K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Social Cognitive Perspective on Personality

1.0K
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Criticisms of the Evolutionary Perspective

380
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

The Behavioral Perspective on Personality01:19

The Behavioral Perspective on Personality

847
Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.

Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

1.1K
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Area of Science:

  • Orthopedic surgery
  • Biomedical engineering
  • Musculoskeletal research

Background:

  • Unicompartmental knee replacement (UKR) is a recognized treatment for advanced knee osteoarthritis.
  • Debates persist regarding optimal patient selection, implant design, and survival rate discrepancies.
  • These unresolved issues may hinder the broader adoption of UKR.

Purpose of the Study:

  • To provide an updated review of current evidence on unicompartmental knee replacement.
  • To critically discuss the most significant controversies surrounding the UKR procedure.

Main Methods:

  • Literature review of recent studies on unicompartmental knee replacement.
  • Analysis of data from national registries and independent case series.
  • Discussion of debated aspects including patient selection and implant design.

Main Results:

  • UKR demonstrates efficacy in selected patients with unicompartmental knee osteoarthritis.
  • Discrepancies in survival rates between registries and case series warrant further investigation.
  • Evidence supports UKR as a viable alternative to total knee replacement in specific populations.

Conclusions:

  • Addressing current controversies in UKR is crucial for its increased acceptance.
  • Further research into patient selection and implant innovation can optimize UKR outcomes.
  • UKR remains an important surgical option for managing unicompartmental knee osteoarthritis.
