What to look for in normal knee radiograph
- The femur is centred on the tibia on both views and the patella sits at a normal height.
- Both tibial plateaux are smooth, with no step, depression or split, and the joint spaces are similar.
- No effusion or fat-fluid level in the suprapatellar recess on the lateral; a fabella behind the knee is a normal sesamoid.
