摘要

Patellofemoral prosthesis procedures are still rarely performed in Germany. However, with strict indications and thorough preoperative preparation, it can be a viable alternative to total knee arthroplasty (TKA). If conservative treatment methods prove ineffective, the question arises not only as to whether the advantages of an isolated joint replacement outweigh those of a total prosthesis, but also regarding patellofemoral joint replacement: should an inlay or an onlay prosthesis be used?
