Background
•OA is the most prevalent form of arthritis
•Big impact on individual health and quality of life and public health in general
•Patients with meniscal tears who also have OA probably do not benefit from arthroscopic surgery [1],
therefore it is important to correctly identify and highlight OA changes on the MRI scans
•There are several established plain film grading systems for osteoarthritis,
we used a simple adaptation for MRI findings:
- Mild: mild cartilage thinning,
small osteophytes
- Moderate: near full thickness cartilage loss,
mild bone marrow oedema,
small cysts,
meniscal extrusion
- Severe: bone on bone,
large subchondral cysts,
marked bone marrow oedema
At our institution,
knee MRI scans are reported by a mixture of musculoskeletal and non-musculoskeletal radiologists according to an alphabetised reporting allocation.
Methods:
We conducted a retrospective muscoskeletal radiologist review of 50 MRI knee scans performed at our institution and initially reported by a mixture of musculoskeletal and non-musculoskeletal radiologists.
•50 patients who had an MRI scan of the knee
•Scans and reports reviewed
•Exclusions:
- Patients less than 40 years old
- Patients with metalwork from previous knee surgery
