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.

New bone outgrowths, called "spurs" or osteophytes, can form on the margins of the joints, possibly in an attempt to improve the congruence of the articular cartilage surfaces in the absence of the menisci. The subchondral bone volume increases and becomes less mineralized (hypo mineralization). [47] All these changes can cause problems ...
Cysts of the jaws are cysts—pathological epithelial-lined cavities filled with fluid or soft material—occurring on the bones of the jaws, the mandible and maxilla.Those are the bones with the highest prevalence of cysts in the human body, due to the abundant amount of epithelial remnants that can be left in the bones of the jaws.
Aneurysmal bone cyst, a benign bone tumor with a radiographic cystic appearance. [13] Baker's cyst or popliteal cyst (behind the knee joint) Mucoid cyst (ganglion cysts of the digits) Stafne static bone cyst (an anatomic variant with radiographic cystic appearance in the posterior mandible) Subchondral cyst (cysts near the bony joints) [14]
Eburnation is a degenerative process of bone commonly found in patients with osteoarthritis or non-union of fractures. Friction in the joint causes the reactive conversion of the sub-chondral bone to an ivory-like surface at the site of the cartilage erosion. [1] The word derives from Latin eburneus, which means "of ivory". [2]
Although failure of chondrocyte differentiation, formation of a fragile cartilage, failure of blood supply to the growth cartilage, and subchondral bone necrosis all have been proposed as the starting point in the pathogenesis, recent literature strongly supports failure of blood supply to growth cartilage as most likely.

Joint space narrowing, with or without subchondral sclerosis. Joint space narrowing is defined by this system as a joint space less than 3 mm, or less than half of the space in the other compartment, or less than half of the space of the homologous compartment of the other knee. II: Obliteration of the joint space III: Bone defect/loss < 5 mm IV
Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. [1] OCD usually causes pain during and after sports. In later stages of the disorder there will be swelling of the affected joint that catches and locks during movement.
