title: Arthroscopic exposure of the patellar articular surface.
abstract: Patellofemoral cartilage degeneration is usually associated with a tight lateral retinaculum (lateral hyperpressure). The position of the patella on the femoral groove under hyperpressure makes reasonable access to the cartilage defects difficult for the arthroscopist. Frequently, the surgeon can barely see the cartilage, and the problem cannot be satisfactorily managed. By performing a lateral release and tilting the patella with a laterally drilled Kirschner wire, the articular surface of the patella can be completely exposed, allowing even perpendicular holes to be drilled whenever necessary.
