Summary
This study precisely maps the anserine bursa and pes anserinus (PA) insertion site. Findings offer improved anatomical guidance for accurate clinical injections in the knee joint.
Area of Science:
- Anatomy
- Orthopedics
- Medical Imaging
Background:
- The pes anserinus (PA) is a complex anatomical structure crucial for knee joint biomechanics.
- Accurate identification of the anserine bursa and PA insertion is vital for effective clinical interventions, such as injections.
Purpose of the Study:
- To delineate the anatomical boundaries and shape of the anserine bursa.
- To define the precise insertion characteristics of the PA tendons.
- To establish recommended injection site parameters for the anserine bursa to enhance clinical practice.
Main Methods:
- Anatomical dissection of 86 Korean cadaver legs.
- Injection of a mixed gelatin solution to visualize the anserine bursa.
- Detailed examination of the PA tendon insertion site and surrounding structures.
Main Results:
- The anserine bursa exhibited an irregularly circular shape, often extending to or above the proximal tibial line.
- The PA tendons (sartorius, gracilis, semitendinosus) demonstrated variable insertion patterns and connections to deep fascial layers.
- Specific anatomical landmarks and angles for an optimal injection site were identified.
Conclusions:
- The study provides detailed anatomical insights into the anserine bursa and PA insertion.
- Recommended injection guidelines are established based on precise anatomical measurements.
- These findings aim to improve the accuracy and efficacy of clinical procedures involving the anserine bursa.

The connective tissues play a significant role in arranging the muscle fibers into a hierarchical structure that forms a complete muscle. Consider a muscle like the bicep brachii, commonly called the bicep. This muscle comprises thousands of muscle fibers enclosed by a protective layer of connective tissue called the endomysium. The endomysium is primarily composed of reticular fibers, a type of thin collagen fiber. It allows the exchange of nutrients and waste products at the fiber level,...

01:19Bones of the Upper Limb: Humerus
11.2K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

01:16Muscles that Move the Forearm
6.1K
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

The testes, also known as testicles, are the male gonads. They are housed within the scrotum, a sac-like structure located beneath the penis. The scrotum's primary role is to regulate the temperature of the testes, which is crucial for sperm production.
Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...

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...
