Summary
Synovial chondromatosis, a condition involving cartilage growth within joints, can occur within the knee or rarely in extra-articular tissues like tendon sheaths. Both intra-articular and extra-articular forms were successfully treated in these presented cases.
Area of Science:
- Orthopedics
- Pathology
Background:
- Synovial chondromatosis is a metaplastic condition characterized by the formation of cartilaginous nodules within the synovium.
- While intra-articular involvement, particularly of the knee, is relatively common, extra-articular presentations are exceptionally rare.
Observation:
- This report details two distinct cases of synovial chondromatosis.
- The first case involved a 25-year-old female with intra-articular synovial chondromatosis of the knee, presenting with pain, swelling, and limited range of motion.
- The second case involved a 22-year-old male with an extra-articular manifestation affecting the medial hamstring tendon sheath of the knee.
Findings:
- The intra-articular case was managed effectively through joint debridement.
- Surgical excision of the extra-articular lesion resulted in complete symptom resolution for the patient.
Implications:
- These cases highlight the importance of considering both intra-articular and rare extra-articular forms of synovial chondromatosis.
- Successful surgical management, including debridement and excision, offers positive outcomes for patients with this condition.
- Further research into the etiology and management of extra-articular synovial chondromatosis may be warranted due to its rarity.

9.4K
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...

01:17Structural Joints: Cartilaginous Joints
4.7K
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

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.

01:20Structural Classification of Joints
8.4K
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.

01:07Development of the Limb Synovial Joints
2.6K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

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...
