Mako Partial Knee

Robotic-Arm Assisted Surgery

Allows you to perform partial knee procedures, which can be difficult to perform manually.

The outcomes you can achieve have the potential to create the future of your orthopaedic service line.

While partial knee replacement accounts for less than 10% of all knee arthroplasty performed, studies have indicated the incidence could be 20% or more depending on timing of surgery with the disease process.1
 
Mako Partial Knee Technology facilitates enhanced precision2,3 and enables you to perform technically challenging partial knee procedures.

Publication:


The Journal of Bone and Joint Surgery, April 2016, Volume 98, Issue 8, Pages 627-635


Goal of study:


To evaluate the accuracy of component positioning to plan for unicompartmental knee arthroplasty (UKA) comparing robotic-arm assisted and conventional surgical techniques


Materials and methods:

  • Prospective, single-center, level I, blinded, randomized controlled trial
  • 139 patients were randomly assigned treatment with either a robotic-arm assisted Mako Partial Knee or a manual surgical procedure using a Biomet Oxford
  • Post-operative CT scan was performed at three months to assess the accuracy of the planned vs. achieved component positioning in the axial, coronal, and sagittal planes
  • Fisher exact test and chi-square test were used to compare categorical data Improved accuracy of component positioning with robotic-assisted unicompartmental knee arthroplasty: data from a prospective, randomized controlled study

Results:

  • Mako Partial Knee showed more accurate component positioning to plan with lower root mean square (RMS) errors and significantly lower median errors in all six component parameters (p<0.01)
  • The proportion of patients with component implantation within 2° of target position was greater in Mako Partial Knee compared to the manual cohort with significance in 5/6 parameters (p<0.05) (See Figure 1)


Conclusion:

  • UKA with Mako Partial Knee led to improved accuracy of component positioning to plan compared with conventional surgical techniques
