Abstract:
A personalized intelligent navigation and positioning apparatus and method for unicompartmental knee arthroplasty. The personalized intelligent navigation and positioning apparatus for unicompartmental knee arthroplasty comprises a guide plate body (1); the guide plate body (1) is provided with an osteotomy groove (2) and a through hole (3) with a rectangular cross section; a depth direction of the osteotomy groove (2) is the same as a height direction of the through hole (3); a length direction of the osteotomy groove (2) is the same as a depth direction of the through hole (3); a groove bottom of the osteotomy groove (2) is higher than the top of the through hole (3); an osteotomy opening direction of the osteotomy groove (2) faces the top of the guide plate body (1); an osteotomy opening of the osteotomy groove (2) points to an anterior superior iliac crest in a flexion position. The apparatus can avoid postoperative pain, prosthesis dislocation, loosening, sinking, poor rotational alignment, postoperative infection, and other complications caused by osteotomy performed by doctors according to their own experience during the operation, and improve the success rate of the surgery and the survival rate of a prosthesis.
