The skyline (patellar sunrise) view is an axial knee radiograph taken with the knee flexed to image the patellofemoral joint. The X‑ray beam is directed tangentially to the patella and trochlear groove, optimizing visualization of patellar facets, alignment, subluxation/dislocation, fractures, and cartilage/articular surface changes. It assesses patellar tracking and damage not seen on standard AP or lateral views.

A knee lateral view X-ray is a side‑view radiograph that shows the femur, tibia, fibula, patella and the knee joint space. It helps detect fractures, dislocations, joint effusions, osteoarthritis changes and alignment abnormalities. The image is usually taken with the knee slightly flexed to visualize the patellofemoral and posterior joint spaces and is used alongside other views for diagnosis and surgical planning.

The skyline (axial/sunrise) radiographic view of the patella visualizes the patellofemoral joint. It's used to assess patellar alignment and tracking, detect fractures or osteochondral fragments, evaluate patellofemoral osteoarthritis and chondral lesions, and guide management of dislocation or instability. It complements AP and lateral knee films when patellar pathology or anterior knee pain is suspected.

Position the patient supine or seated with the knee flexed about 40–60°. Place the image receptor beneath the distal femur or under the patella. Direct the x‑ray beam tangentially to the patellofemoral joint with a cephalad angulation of roughly 10–30° (adjust for anatomy) to visualize the articular surface. Collimate to the joint, use shielding, and ask the patient to remain still.

A skyline view is the visual outline of a city or landscape formed by buildings, towers and other structures against the sky, typically seen from a distance or elevated vantage point. It highlights distinctive architectural features that create an identifiable silhouette, used for orientation, tourism and photography. Skylines change with development and lighting, offering dramatic daytime and nighttime vistas.

Cost of a skyline (patellar sunrise) X‑ray varies by country and facility. In India private clinics it’s roughly ₹200–₹800 (≈$2–$10). In the UK it’s usually free on the NHS; private clinics charge about £30–£120 (≈$40–$150). In the US private X‑rays typically run $50–$300 depending on facility and add‑ons. Exact price depends on location and whether a radiologist report is included—call ahead.
