Of these, 39 patients had evidence of subchondral edema or subchondral cyst on the preoperative MRI with maintained joint space on preoperative radiographs. Krych AJ, King AH, Berardelli RL, Sousa PL, Levy BA. Thirty-six patients (18 men, 18 women) with a mean age of 41 years (range, 19-67 years) had subchondral edema, with or without the presence of cystic acetabular changes, at minimum 2-year follow-up (range, 24-60 months). However, there remains a subset of hips with relatively maintained joint space but with acetabular subchondral edema and cystic change with unknown outcome on magnetic resonance imaging (MRI). Epub 2019 Jun 24. MRI shows a well defined, regular, complex heterogenously altered lobulated completely intraosseous lesion in the subchondral location of the glenoid with no expansion / bleed / labral / cartilage / joint involvement. Purpose: 2020 Oct 22;9(10):e1531-e1539. 2. The presence of a subchondral edema with an acetabular cyst on MRI is indicative of a full-thickness cartilage lesion at the time of arthroscopy. For patients who did not require hip arthroplasty or revision arthroscopy, patients demonstrated significant improvement in symptoms compared with the preoperative state. RESULTS: We identified 58 subchondral cystsin 43(71.7%) of 63 cases. 4. Subchondral bone cysts commonly occur adjacent to a treated focal cartilage defect and are possibly connected to the joint cavity. 2020 Sep 29;9(9):e1375-e1379. Overall, 104 patients were included. MRI tends to make these lesions look much more worrisome than they really are. In the region of subchondral edema, in osteoarthritis the most common pathological changes are necrosis, fibrosis, and trabecular abnormalities [ 22 ].

Dr. Nwachukwu will often be able to see acetabular paralabral cysts or subchondral cysts on an MRI scan.   Subchondral cysts occur is when the damage done to the cartilage begins to harden and form fluid-filled sacs (cysts) within the joint. (1) To correlate MRI findings of subchondral acetabular edema/cystic change with arthroscopy grading of articular cartilage and (2) to determine whether postoperative outcome was worse for patients with subchondral edema/cystic change compared with a matched control group.

Enhancement of subchondral cysts was evaluated on contrast-enhanced MRI as grade 0 (absent), grade 1 (partial enhancement), or grade 2 (full enhancement). Bone contusion theory proponents explain that subchondral bone that has lost some of the overlying cartilage cushion is more susceptible to injury from repetitive microtrauma. [6, 20]. Minimum 2-year outcomes were compared using prospectively collected Hip Outcome Score (HOS) activities of daily living and sport subscales as well as the modified Harris Hip Score (mHHS). eCollection 2020 Jul. Am J Sports Med. doi: 10.1016/j.eats.2020.06.015. The mean mHHS was inferior for all patients with subchondral edema/cystic change (79.9 ± 18.7 vs 86.6 ± 12.5; P = .03), and the HOS was also lower (69.1 ± 27.0 vs 79.5 ± 21.4; P = .02). The exact pathogenesis of these degenerative cysts is not certain.26,27 Subchondral cysts are most often seen in association with osteoarthritis, but may occur as the result of degeneration or injury of the overlying articular cartilage by other causes. Geode is a term borrowed from "geology", where it refers to rounded formations in igneous and sedimentary rocks. The index cases demonstrate a subchondral fracture, which progresses to osteonecrosis and cortical collapse. It's a fluid-filled sac that forms in one or both of the bones that make up a joint. The cyst usually forms in the subchondral area of the joint which is just underneath the cartilage. An MRI allows him to see both the bony structures of the hip as well as the soft tissues. Ligaments. For a patient reporting symptoms, a doctor may recommend an X-ray to rule out other problems, but the cyst is usually found through magnetic resonance imaging (MRI). Am J Sports Med.
