What is meniscal Chondrocalcinosis?
Chondrocalcinosis refers to the calcification in the menisci or articular cartilage due to the deposition of calcium pyrophosphate dihydrate crystal, dicalcium phosphate dihydrate, calcium hydroxyapatite crystals, or a combination of these [1, 2].
What is Chondrocalcinosis of the knee?
Chondrocalcinosis, also known as calcium pyrophosphate deposition (CPPD) and pseudogout, is a condition where calcium pyrophosphate crystals build up in the joints. It is a type of arthritis that causes inflammation, stiffness, tenderness, redness, and warmth of the joints.
What is calcification of the meniscus?
Meniscal calcifications can be due to trauma, degenerative disease, or crystal arthropathies such as calcium pyrophosphate crystal deposition disease (1–4). The presence of meniscal calcifications is of clinical importance because several authors (5–10) have suggested that they are associated with knee osteoarthritis.
Will a healed meniscus show up on an MRI?
Conclusion. MRI has its limitation in evaluating meniscal healing status after repair with bioabsorbable arrows, especially for PD and T1 serials. Among all the five serials, T2 serials are most accurate and have lower proportion of double side Grade 3 signal for completely healed meniscus.
Is chondrocalcinosis serious?
Chondrocalcinosis 2 is a rare disease characterized by the accumulation of calcium pyrophosphate dihydrate (CPP) crystals in and around the joints. A buildup of these crystals can lead to joint pain and damage that is progressive (worsens over time).
What is mild chondrocalcinosis?
Chondrocalcinosis, also known as calcium pyrophosphate deposition (CPPD) disease, is a condition in which calcium pyrophosphate crystals build up in the joints. The deposits cause irritation that lead to inflammation and cartilage damage. The symptoms can be similar to gout and other types of arthritis.
How serious is chondrocalcinosis?
Is Chondrocalcinosis serious?
Is Chondrocalcinosis and osteoarthritis?
Chondrocalcinosis is associated with osteoarthritis (OA) (1) and several studies have found an association between the presence of CPP crystals in synovial fluid and radiographic severity of OA (2, 3).
Is chondrocalcinosis painful?
Is exercise good for chondrocalcinosis?
Exercise and therapy Range of motion exercises are particularly helpful during times when CPPD crystal deposition disease is active. These are gentle exercises done without any weights and designed to preserve the mobility of the joint.
Does meniscal chondrocalcinosis affect the MR imaging of knee menisci?
Effect of chondrocalcinosis on the MR imaging of knee menisci MR imaging sensitivity and specificity for detection of meniscal tear is decreased in the presence of meniscal chondrocalcinosis. Chondrocalcinosis appeared as a high-signal-intensity region on T1-weighted, intermediate-weighted, and inversion recovery sequences.
How accurate is MR imaging in the diagnosis of chondrocalcinosis?
The accuracy of MR imaging in the detection of meniscal tears in patients with chondrocalcinosis is 23 (62%) of 37, with 95% confidence limits of 45-78%.
How accurate is MR imaging for the diagnosis of meniscal tears?
Results: In the chondrocalcinosis group, MR imaging sensitivity, specificity, and accuracy for meniscal tear were 78%, 71%, and 78%, respectively, for the lateral meniscus, and 89%, 72%, and 81% for the medial meniscus.
Does discoid meniscus tear show up on MRI?
Tears are more common with the complete discoid meniscus variant and often display horizontal or longitudinal tear patterns ( 32 ). MR imaging has widely variable sensitivity and specificity for detection of tears within a discoid meniscus because of the increased meniscal vascularity and diffuse intrameniscal signal intensity ( 34, 35 ).
