The Merchant view is an axial (tangential) X‑ray of the patellofemoral joint — a sunrise/skyline projection used to assess patellar alignment, subluxation, trochlear morphology and joint‑space/cartilage changes. It’s obtained with the patient supine, knees flexed about 40–45°, cassette at the anterior knees and the X‑ray beam angled caudally (≈30°) through the patellofemoral joint.

Merchant view refers to the seller’s interface in an e-commerce platform that consolidates order management, inventory, pricing, payments, shipping status, customer communications, and sales analytics. It provides tools to process returns, update listings, run promotions, and monitor performance metrics in real time. This dashboard-centric perspective helps merchants manage operations efficiently, respond to customer needs, and optimize revenue and fulfillment workflows.

The Merchant (patella) position is an axial radiographic view of the patellofemoral joint. The patient lies supine with knees flexed about 45°, feet on the table; the cassette is placed under the knees and the X‑ray beam directed caudally (≈30°). It demonstrates patellar alignment, tilt, subluxation and articular cartilage to assess maltracking, chondromalacia or patellar fractures.

"Merchant view" is a standardized axial (skyline) patellar radiograph taken supine with knees flexed about 45° and the x‑ray beam angled caudally (commonly ~30°), giving bilateral patellofemoral comparison. "Sunrise view" (skyline) is a more general axial patellar projection obtained at variable knee flexion (often up to 90°) with a tangential beam to visualize patellar‑trochlear articulation. Merchant is a specific technique; sunrise is the broader category.

Standard radiographs are typically obtained in two orthogonal views: frontal (anteroposterior or posteroanterior — AP/PA) and lateral. The frontal view shows width and vertical relationships; the lateral view provides depth and separates overlapping structures. Using both views helps localize lesions, detect fractures, and assess alignment or pathology that may be obscured on a single projection.

Patellofemoral pain syndrome (often called runner’s knee) is the most common knee injury, especially in active people. It causes pain around or behind the kneecap, worsened by running, squatting, stair climbing or prolonged sitting. Treatment usually includes activity modification, physiotherapy focusing on quadriceps and hip strengthening, pain relief and gradual return to activity. Seek medical review for swelling, locking, or instability.
