What is the term used to describe an osteochondral fracture that typically involves the medial femoral condyle?

The term that describes an osteochondral fracture typically involving the medial femoral condyle is osteochondritis dissecans. This condition is characterized by a focal area of cartilage and underlying bone becoming necrotic, leading to a fracture and potential separation of a fragment of the bone and cartilaginous surface. It often occurs in the knee joint, particularly affecting the medial femoral condyle, and is commonly seen in adolescents and young adults who are active in sports.

This condition may present with pain, swelling, and limited range of motion, and if left untreated, it can lead to joint instability and long-term issues such as early onset osteoarthritis. Effective management often involves rest, physical therapy, and in some cases, surgical intervention to repair or remove the affected cartilage or bone fragment.

The other terms listed refer to different conditions. Osteoarthritis is a degenerative joint disease characterized by the breakdown of cartilage and underlying bone, commonly related to aging and wear-and-tear. Osteomyelitis is an infection of the bone, often arising from bacteria. Osteoporosis refers to a condition where bones become weak and brittle, increasing the risk of fractures but does not specifically describe an osteochondral fracture.
