Muscles that Move the Arm01:31

Muscles that Move the Arm

4.9K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

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...

Total Voids in Concrete01:12

Total Voids in Concrete

502
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

13.5K
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.

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview01:13

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

1.3K
Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.
The ATR process begins by directing a beam...

Area of Science:

  • Orthopedic Surgery
  • Robotics in Medicine
  • Surgical Technology

Background:

  • Robotic arm-assisted total knee arthroplasty (RATKA) presents potential benefits over traditional methods.
  • Comprehensive assessment of RATKA technology is crucial for understanding its clinical utility.

Purpose of the Study:

  • To review and assess the accuracy, precision, and soft-tissue protection offered by RATKA.
  • To evaluate patient satisfaction, learning curve, and other potential advantages of robotic-assisted knee surgery.
  • To synthesize current evidence on the benefits of RATKA.

Main Methods:

  • A literature review was conducted using the PubMed database.
  • Included studies reported clinical outcomes, cadaver results, radiographic outcomes, surgeon experience, and robotic accuracy.
  • Forty articles were selected for the final analysis.

Main Results:

  • RATKA may offer enhanced component accuracy and precision in total knee arthroplasty.
  • Potential benefits include improved soft-tissue protection, increased patient satisfaction, and a shorter learning curve.
  • Other advantages include optimal ergonomic design and reduced surgeon/team fatigue, potentially improving outcomes.

Conclusions:

  • Current studies highlight the potential advantages of RATKA, primarily based on short-term outcomes.
  • Longer-term studies are anticipated to further validate the use of RATKA for improved patient satisfaction and clinical results.
  • Continued research is essential to confirm the long-term efficacy of robotic assistance in knee replacement.
