Some unicameral bone cysts may spontaneously resolve without medical intervention. Specific treatments are determined based on the size of the cyst, the strength of the bone, medical history, extent of the disease, activity level, symptoms an individual is experiencing, and tolerance for specific medications, procedures, or therapies.

In the temporomandibular joint, subchondral sclerosis of the mandibular condyle has been described as an early change, condylar flattening as a feature of progressive osteoarthritis, and narrowing of the temporomandibular joint space as a late stage change. [14] A joint space of between 1.5 and 4 mm is regarded as normal. [15] Ankle osteoarthritis.
Osteoarthritis (OA) is a type of degenerative joint disease that results from breakdown of joint cartilage and underlying bone. [5] [6] It is believed to be the fourth leading cause of disability in the world, affecting 1 in 7 adults in the United States alone. [7]
Medical condition Osteochondritis dissecans A large flap lesion in the femur head typical of late stage Osteochondritis dissecans. In this case, the lesion was caused by avascular necrosis of the bone just under the cartilage.

They may pass from the main joint cavity into a neighboring synovial cyst. For this reason, a mass may not be appreciated within the actual joint space itself. [citation needed] Additional radiographic findings include joint effusion and degenerative changes such as joint space narrowing, subchondral sclerosis, and osteophyte formation.
Other relatively common sites include the upper arm bone, knee, shoulder, and ankle. [1] Diagnosis is typically by medical imaging such as X-ray, CT scan, or MRI. [1] Rarely biopsy may be used. [1] Treatments may include medication, not walking on the affected leg, stretching, and surgery. [1]
A latent cyst is located away from the epiphyseal plate and is more likely to heal with treatment. [4] It is typically diagnosed in under 20 year olds. [1] Although unicameral bone cysts can form in any bone structure, it is predominantly found in the proximal humerus and proximal femur; additionally, it affects males twice as often as females ...
However, acute traumatic osteochondral lesions or surgically created lesions extending into subchondral bone, e.g. by Pridie drilling, [2] spongialization [3] abrasion [4] or microfracture causing the release of multipotent mesenchymal stem cells from the bone marrow, may heal with repair tissue consisting of fibrous tissue, fibrocartilage or ...
