The capsule of the glenohumeral (shoulder) joint is the articular capsule of the shoulder.It completely surrounds the joint. It is attached above to the circumference of the glenoid cavity beyond the glenoidal labrum, and below to the anatomical neck of the humerus, approaching nearer to the articular cartilage above than in the rest of its extent.
The articular capsule of the knee joint 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. [1] The capsule consists of an inner synovial membrane, and an outer fibrous membrane separated by fatty deposits anteriorly and posteriorly. [2]

The hardening of the shoulder joint capsule is central to the disease process. This is the result of scar tissue around the joint capsule. [14] There also may be a reduction in synovial fluid, which normally helps the shoulder joint, a ball and socket joint, move by lubricating the gap between the humerus and the socket in the shoulder blade.
Each capsule consists of two layers or membranes: an outer (fibrous membrane, fibrous stratum) composed of avascular white fibrous tissue; an inner (synovial membrane, synovial stratum) which is a secreting layer; On the inside of the capsule, articular cartilage covers the end surfaces of the bones that articulate within that joint.
MRI-scans are becoming more valuable in the analysis of articular cartilage but their use is still expensive and time-consuming. X-rays show only bone injuries and are therefore not very helpful in diagnosing cartilage damage, especially not in early stages. The best tool for diagnosing articular damage is the use of arthroscopy. [citation needed]
The articular capsule has a synovial and a fibrous membrane separated by fatty deposits. Anteriorly, the synovial membrane is attached on the margin of the cartilage both on the femur and the tibia, but on the femur, it communicates with the suprapatellar bursa or recess and extends the joint space proximally.
The joint capsule is a soft tissue envelope that encircles the glenohumeral joint and attaches to the scapula, humerus, and head of the biceps. It is lined by a thin, smooth synovial membrane . The rotator cuff is a group of four muscles that surround the shoulder joint and contribute to the shoulder's stability.
