New technique: practical procedure of robotic arm-assisted (MAKO) total hip arthroplasty

Jianghui Qin et al. Ann Transl Med. 2018 Sep.

Abstract

Robotic-arm facilitated orthopaedic surgeons perform individualized and precise arthroplasty surgery. This system (MAKO) has been recently introduced into China and conducted total hip arthroplasty in several central hospitals. The pre-operative preparation and surgical procedures, together with some precautions for surgery, are outlined here to familiarize this technique to the orthopaedic surgeons in China.

Keywords: MAKO; Total hip arthroplasty; robotic surgery.

Figures

Figure 1
Figure 1
The established 3D model based on patient’s CT data. Estimated hip length and offset compared to opposite hip and pre-operation hip joint was displayed.
Figure 2
Figure 2
Mock installation showed the orientation and depth of the acetabular component in the transverse view of the hip joint.
Figure 3
Figure 3
A preoperative 3D model showed the 5 mm length deficit and 2 mm decrease combined offset of right-side hip joint.
Figure 4
Figure 4
Estimated postoperative effect after the acetabular component was installed. Cup size could be selected in the right column. Cup orientation could be adjusted in the frame of the main screen. The distance between rotation centers of the cup and the original acetabulum was also shown in the main screen.
Figure 5
Figure 5
Fine adjustment could be made according to the images of the coronal section (as highlighted) by using the small button on the upper left frame. The same operation could also be performed on transverse and sagittal sections.
Figure 6
Figure 6
The estimated effect after femoral component installation. The orientation of stem could also be adjusted on the transverse and sagittal sections.
Figure 7
Figure 7
The estimated postoperative effect was shown. The length and offset changes of the hip joint compared to opposite side and preoperative condition was demonstrated.
Figure 8
Figure 8
The estimated effect of the pre-surgical plan (A) and the post-surgical anterior-posterior view of the hip joint (B). The result showed extremely high consistency between the surgical plan and the final result.
