The skyline (sunrise) view is a tangential axial radiograph of the patella taken with the knee flexed, visualizing the patellofemoral joint and anterior femoral condyles. It highlights patellar alignment, tilt, subluxation, chondral surface irregularities and marginal fractures. Multiple flexion angles may be used to better reveal articular step-offs or instability; it is ordered when patellar injury or instability is suspected.

A knee lateral view X‑ray is a side‑view radiograph of the knee taken with the joint slightly flexed to profile the femur, tibia, patella and joint space. It helps detect fractures, dislocations, joint effusion, loose bodies, patellar alignment problems and degenerative changes, and complements an AP view for comprehensive assessment and surgical planning.

The skyline (axial or "sunrise") view is an X‑ray projection of the patella taken with the knee flexed to image the patellofemoral joint tangentially. It helps detect patellar fractures, subluxation or dislocation, articular surface irregularities, osteochondral defects, and patellofemoral osteoarthritis, and assesses patellar tracking and joint‑space narrowing, complementing AP and lateral knee views.

Position the patient seated or supine with the knee flexed about 45–60° over the table edge. Place the detector under the patella and direct the x‑ray beam tangentially to the patellofemoral joint (typically angled 15–30° to the table, depending on flexion). Collimate to the patella, have the patient remain still, and expose. The skyline (sunrise) view shows patellar alignment and fractures.

A skyline view is the visible outline of a city’s buildings and structures against the sky, usually seen from a distance or elevated vantage point. It emphasizes distinctive elements like skyscrapers, bridges, and landmarks, reflecting a city’s architectural character. Skyline views are prized for aesthetics, tourism, photography, and real estate, and they vary with lighting, weather, and urban growth.

Cost for a skyline (patellar/sunrise) X‑ray varies by country and provider. It’s often free under public health systems; in private settings expect roughly: India ₹200–1,500; UK private clinics £30–120; US outpatient centres $50–300. Additional fees may apply for radiologist interpretation or urgent appointments; specialised imaging (CT/MRI) costs substantially more. Ask local radiology centres for exact pricing.
