Here’s a clear overview of an X-ray of the knee joint 🦴:
1. What it shows
An X-ray captures bones and joint spaces but not soft tissues like cartilage, ligaments, or tendons. For the knee, it highlights:
- Femur (thigh bone) – upper part of the joint
- Tibia (shin bone) – lower part of the joint
- Patella (kneecap) – sits in front of the joint
- Joint space – gap between femur and tibia where cartilage sits (cartilage itself isn’t visible)
2. Common X-ray views
- Anterior-Posterior (AP) view – from front to back
- Lateral view – side view
- Sunrise/skyline view – shows the patella
- Oblique view – angled perspective for subtle details
3. Why it’s done
- Detect fractures or dislocations
- Assess arthritis (joint space narrowing, bone spurs)
- Check for bone tumors or cysts
- Evaluate post-surgery healing or alignment
4. Limitations
- Cannot show soft tissues like ligaments, tendons, or menisci
- Small fractures or subtle cartilage issues may require MRI or CT
5. Radiologist looks for
- Bone alignment and patella position
- Joint space symmetry
- Osteophytes (bone spurs)
- Any fractures, lesions, or degenerative changes
If you want, I can create a labeled diagram showing a knee X-ray with bones and joint spaces so you can see exactly what each part looks like on the image.
Do you want me to do that?
