In our patients, from the follow-up X-ray and MRI we observed a satisfied regeneration of the subchondral bone without bone resorption or recurrence of the cyst, indicating that cancellous bone autograft is an effective method for treating subchondral cysts. Furthermore, the successful reconstruction of the subchondral bone significantly relieved the patients' symptoms, as the postoperative VAS score was obviously improved and no donor site morbidity was seen in this study.
There were three cases of osteoarthritis showing superolateral space narrowing and osteophytes in all three (100%), articular erosion in 2 (67%), and subchondral cysts in 2 cases (67%).
MRI is also able to detect small T2 hyperintense subchondral cysts and erosions before they are radiographically apparent.
(Figures (5)-AP with joint not closed and (6)-45[degrees] flexion PA with joint closed laterally) Make sure to document specific abnormalities on the radiographs with a particular emphasis on subchondral cysts, subchondral sclerosis, periarticular osteophytes, and joint subluxation.

Total knee replacement (TKR) is most commonly caused by osteoarthritis of the knee, and can result in loss of articular cartilage, subchondral bone sclerosis, bone spurs and degenerative subchondral cysts. Some patients experience extreme inflammation, joint stiffness and pain.
An X-ray revealed degenerative changes of the humeral head, including subchondral cysts and narrowing of the joint space.
The main pathological findings of MRI were as follows: pathologically increased fluid in the joints, bone marrow edema, subchondral cysts, tendinitis, and soft tissue edema.
Intraosseous ganglia when associated with osteoarthrosis may be difficult to divorce from large subchondral cysts. They are, therefore, more confidently identified radiographically in the young without joint space narrowing or productive changes.
Classic radiographic features "are focal joint space narrowing, osteophyte, subchondral bone sclerosis, and subchondral cysts."
