The X-ray technique for the tangential visualization of the patellofemoral joint is described; 3 X-ray signs (patellofemoral angle, patellofemoral index and patellofemoral displacement) are proposed as diagnostic aids in cases of subluxation of the patella and chondromalacia patellae. Theoretically, the pathogenesis of chondromalacia patellae and patellofemoral osteoarthritis may be explained as manifestations of cartilage damage secondary to lateral patellofemoral hyperpressure and medial patellofemoral hyperpressure.
描述了用于髌股关节切线位可视化的X线技术；提出了3种X线征象（髌股角、髌股指数和髌股移位）作为髌骨半脱位和髌骨软骨软化症病例的诊断辅助手段。从理论上讲，髌骨软骨软化症和髌股骨关节炎的发病机制可解释为髌股外侧高压和髌股内侧高压继发软骨损伤的表现。
