Menisci calcification is seen with
**Core Concept**
Meniscal calcification is a rare condition characterized by the deposition of calcium salts within the menisci of the knee joint. This phenomenon is often associated with underlying degenerative joint disease, trauma, or metabolic disorders.
**Why the Correct Answer is Right**
Calcification of the menisci typically occurs in the setting of osteoarthritis, where the breakdown of cartilage and the subsequent exposure of underlying bone lead to the deposition of calcium salts. This process is often facilitated by the presence of inflammatory mediators and the activation of osteoblasts, which are responsible for bone formation. In some cases, calcification may also be seen in association with conditions such as hypoparathyroidism, hyperparathyroidism, or pseudogout.
**Why Each Wrong Option is Incorrect**
**Option A:** Meniscal tears are a common condition characterized by damage to the menisci, but they are not typically associated with calcification.
**Option B:** Osteochondritis dissecans is a condition that involves the separation of cartilage and bone within the joint, but it is not typically associated with calcification of the menisci.
**Option C:** Ligament calcification is a condition that involves the deposition of calcium salts within ligaments, but it is not typically associated with meniscal calcification.
**Clinical Pearl / High-Yield Fact**
Meniscal calcification is often seen in association with osteoarthritis, and its presence can be an important diagnostic clue in the evaluation of patients with knee pain.
**Correct Answer:** D. Osteoarthritis
