What is the function of the articular capsule?
The fluid-filled bursae and fat pad of the articular capsule function to provide cushion and protection to the joint whenever the knee joint moves.
What is articular capsule of knee joint?
The articular capsule of the knee joint (commonly referred to as the capsular ligament) is the wide and lax joint capsule of the knee. It is thin in front and at the side, and contains the patella, ligaments, menisci, and bursae of the knee.
What is the function of articular capsule in a synovial joint?
The walls of the joint cavity are formed by the articular capsule. Friction between the bones is reduced by a thin layer of articular cartilage covering the surfaces of the bones, and by a lubricating synovial fluid, which is secreted by the synovial membrane.
What is capsular structure?
It is a dense fibrous connective tissue that is attached to the bones via specialised attachment zones and forms a sleeve around the joint. It varies in thickness according to the stresses to which it is subject, is locally thickened to form capsular ligaments, and may also incorporate tendons.
Where does the knee capsule attach?
Deep part: a vertical thickening of the knee joint capsule found underneath the superficial part of the tibial collateral ligament. It originates from the area of the distal femur, then attaches to the medial meniscus, and terminates on the proximal tibia.
Where does the articular capsule of the synovial joint attach to in relation to the bone?
Synovial joints are characterized by the presence of a joint cavity. The walls of this space are formed by the articular capsule, a fibrous connective tissue structure that is attached to each bone just outside the area of the bone’s articulating surface.
What are the two layers of the articular capsule?
It consists of two layers, an outer fibrous layer and an inner layer known as the synovial membrane. Also known as the synovium, it consists of a synovial lining and the supporting stromal tissue. It produces synovial fluid that lubricates the joint.
What is a capsular injury of the knee?
Injury to the capsular ligaments of the knee commonly occurs in conjunction with cruciate ligament injury. An untreated grade III sprain can lead to recurrent meniscal injury, failure of cruciate ligament reconstruction, and arthrosis.

Adhesive capsulitis is a common inflammatory condition with characteristic imaging features that should be considered in the absence of alternative diagnoses.
What does the capsule of a joint contain?

What is a joint capsule?
Medical Definition of joint capsule : a ligamentous sac that surrounds the articular cavity of a freely movable joint, is attached to the bones, completely encloses the joint, and is composed of an outer fibrous membrane and an inner synovial membrane.
Can you repair articular cartilage damage?
Surgical Treatment. Surgery is often the best treatment option for damaged articular cartilage since it does not heal well on its own. Some surgeries aim to relieve symptoms, while other surgical procedures are intended to repair and restore damaged articular cartilage.

What is inside the knee joint capsule?
– The suprapatellar plica dividing the suprapatellar recess – The infrapatellar plica, in front of the anterior cruciate ligament, reaches from the intercondylar notch to the infrapateller fat pad – The medial patellar plica, located adjacent to the patella’s medial facet, runs vertically along the medial joint capsule
Which joint has a fibrous articular capsule?
The articular capsule of the knee joint surrounds the knee and consists of two main layers, an outer and inner layer. The outer layer is made up of a tough, fibrous membrane that is made up of ligament tissue. The inner layer is made up of a synovial membrane, which secretes, a clear, yellowish fluid called synovial fluid.
