Articular cartilage abnormalities of the knee are a cause of significant patient morbidity. Several surgical techniques have been developed to treat these lesions to improve patient symptoms and to delay or prevent the development of osteoarthritis. MRI has been shown to be an accurate non-invasive test for the evaluation of articular cartilage injuries and for evaluating the postoperative knee following chondral repair. As these surgical repair techniques become more commonly performed, is important for radiologists to be familiar with the surgical techniques and the MRI appearance of the postoperative knee including both normal and abnormal findings. In this article, these chondral repair techniques will be reviewed as well those normal and abnormal MRI findings following these surgeries.
A 50-year-old woman presented with a 30-year history of nasal obstruction. She had been treated for paranasal sinusitis at other hospitals and she was referred to our hospital for further examination. Flexible endoscopy revealed a mass in the posterior aspect of the right nasal cavity to the posterior aspect of the left nasal cavity around the posterior edge of the nasal septum.
Osteoarthritis is the most common type of arthritis and a frequent cause of pain and disability. A number of exciting surgical treatment modalities have been introduced recently, including autologous chondrocyte transplantation and osteochondral allografting or autografting. MR imaging offers the distinct advantage of visualizing the articular cartilage directly. MR imaging can detect signal and morphologic changes in the cartilage and has been used to detect cartilage surface fraying, fissuring, and varying degrees of cartilage thinning.
