Patient-specific TKA Model: Patella

This lecture discusses the development of a patient-specific total knee arthroplasty (TKA) model focusing on patellar problems such as fractures, implant issues, and anterior knee pain. It covers the creation of knee and patellar models, implant positioning, extensor mechanism modeling, and validation techniques. The lecture also explores the identification of material properties using CT scans, application to real patients, and the correlation between strain and body weight. The model's potential as a surgical planning tool and its clinical applications are highlighted, emphasizing the importance of patellar density, volume, and body weight in preoperative planning.
