Visible features, with the limitation that this is a photograph of an X-ray film rather than the original images:
This looks more like a
chronic wear-and-tear pattern than an acute bony injury, but a formal radiology report is needed, especially because subtle fractures, cartilage/meniscus injuries, and ligament injuries may not show on a plain X-ray. The
ACR knee imaging guidance supports radiographs as an initial test, with MRI considered when symptoms suggest internal soft-tissue injury or when X-rays do not explain significant symptoms.
Seek urgent in-person assessment if there is inability to bear weight, rapidly increasing swelling, fever/redness, deformity, numbness, or severe pain after an injury.
