With the aging of the population, more and more patients will benefit from Total Knee Arthroplasty (TKA) in China. The poor movement of the patellofemoral joint due to the malalignment of the prosthesis after TKA is one of the important cause of the knee revision surgery, which needs further attention. The alignment of the knee prosthesis involves correct position, alignment, osteotomy of tibia and femur and placement of prosthesis.
