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...

Arteries of Lower Limbs01:20

Arteries of Lower Limbs

4.7K
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Veins of Lower Limbs01:15

Veins of Lower Limbs

2.6K
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

Design Example: Alignment of a Road Line Using GIS

350
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Veins of Upper Limbs01:17

Veins of Upper Limbs

4.3K
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

2.4K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Summary
This summary is machine-generated.

Successful total knee arthroplasty depends on limb alignment. While neutral alignment was favored, recent studies challenge this, exploring kinematic alignment for better outcomes.

Area of Science:

  • Orthopedic Surgery
  • Biomechanics

Background:

  • Postoperative coronal lower limb alignment is critical for total knee arthroplasty (TKA) success.
  • Neutral alignment has been historically linked to improved prosthesis survival and knee function.

Purpose of the Study:

  • To review current research on neutral alignment versus kinematic alignment in TKA.
  • To provide guidance for clinical TKA operations regarding lower limb alignment.

Main Methods:

  • Review of recent studies comparing neutral and kinematic alignment in TKA.
  • Discussion of surgical axes, alignment principles, and osteotomy techniques in TKA.

Main Results:

  • Evidence suggests neutral alignment may not be universally optimal for TKA.
  • Kinematic alignment is emerging as a potentially superior alternative in certain cases.

Conclusions:

  • The traditional emphasis on neutral alignment in TKA requires re-evaluation.
  • Clinical practice should consider kinematic alignment strategies for improved TKA outcomes.
