摘要

Patella baja is a complex challenge for the treating orthopedic and trauma surgeons. It can occur acutely as a result of injury and postoperative changes in joint symmetry and can also develop as a result of operative interventions and injury. Clinically, it is characterized by anterior knee pain and often by limited range of motion. The diagnosis and quantification are based on lateral imaging (X-ray, magnetic resonance imaging, MRI, computed tomography, CT) and various indices which can describe the height of the patella. In summary, a differentiation must be made between a true patella baja and a supposed patella baja (pseudo-patella baja), which occurs primarily after knee arthroplasty due to a displacement of the joint line. Depending on the cause, surgical treatment is performed by restoring the continuity of the extensor apparatus in acute cases or by optimizing the patella height in terms of a proximalization osteotomy of the tibial tubercle or in revision arthroplasty by restoring the joint line.
