Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

3.4K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Ankle Joint01:10

Ankle Joint

1.5K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Knee Joint01:23

Knee Joint

1.6K
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...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

2.2K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Structural Classification of Joints01:20

Structural Classification of Joints

3.3K
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.
Synarthrosis

Area of Science:

  • Orthopedics
  • Infectious Diseases

Background:

  • Native joint septic arthritis (NJSA) is a critical condition involving synovial membrane inflammation and joint damage.
  • It predominantly affects large joints and is linked to risk factors like diabetes and immunosuppression.

Purpose of the Study:

  • To provide a comprehensive review of NJSA, including diagnosis, treatment, and management strategies.
  • To specifically address challenges in patients with prior ACL reconstruction.

Main Methods:

  • Literature review encompassing epidemiology, pathogenesis, clinical manifestations, diagnosis, and treatment of NJSA.
  • Comparison of arthroscopic versus open debridement surgical techniques.
  • Discussion of antibiotic therapy duration and prophylaxis.

Main Results:

  • NJSA necessitates urgent, multidisciplinary care to avoid permanent joint damage and systemic sepsis.
  • Risk factors significantly increase susceptibility to NJSA.
  • Specific considerations exist for managing NJSA post-ACL reconstruction.

Conclusions:

  • Prompt diagnosis and aggressive treatment are crucial for favorable patient outcomes in NJSA.
  • Further research is needed to optimize NJSA management protocols.
  • Understanding NJSA's multifaceted aspects is key for effective clinical practice.
