Knee Joint01:23

Knee Joint

3.1K
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...

Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

894
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...

Total Voids in Concrete01:12

Total Voids in Concrete

453
Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement...

Total Internal Reflection Fluorescence Microscopy01:05

Total Internal Reflection Fluorescence Microscopy

11.0K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

185
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...

Summary
This summary is machine-generated.

Many total knee replacement patients struggle to kneel, impacting daily life. Research suggests this difficulty isn't solely due to physical limitations but also psychological factors, indicating a need for better patient education and support.

Area of Science:

  • Orthopedics
  • Rehabilitation Medicine
  • Patient Outcomes Research

Background:

  • Kneeling ability is a significant, yet poorly addressed, patient-reported outcome following total knee replacement (TKR).
  • A high percentage of TKR patients (60-80%) report difficulty or inability to kneel, affecting daily activities, self-care, and social engagement.
  • This persistent issue leads to patient dissatisfaction and disappointment, despite the expectation of improved function post-surgery.

Purpose of the Study:

  • To investigate the multifaceted reasons behind persistent kneeling difficulties after total knee replacement.
  • To explore the discrepancy between self-reported and observed kneeling ability in TKR patients.
  • To highlight the need for improved clinical awareness, research, and interventions for this common TKR complication.

Main Methods:

  • Review of existing research on patient-reported outcomes after TKR, focusing on kneeling ability.
  • Analysis of factors contributing to the discrepancy between self-reported and observed kneeling function.
  • Identification of research gaps concerning surgical factors and patient-reported outcomes.

Main Results:

  • No correlation was found between range of motion and self-reported kneeling ability post-TKR.
  • Observed kneeling ability often exceeds self-reported ability, suggesting psychological or behavioral factors influence patient choices.
  • Identified reasons for not kneeling include pain, numbness, fear of prosthesis damage, comorbidities, and healthcare provider advice.

Conclusions:

  • Kneeling difficulties after TKR are multifactorial, involving psychological and educational components beyond physical limitations.
  • There is no inherent clinical contraindication for kneeling on a replaced knee; barriers can be addressed through education and rehabilitation.
  • Further research and increased clinical focus are essential to improve patient care and restore kneeling function after TKR.
