Introducing Mako SmartRobotics
Mako SmartRobotics combines three key components: 3D CT-based planning, AccuStop haptic technology, and insightful data analytics, into one platform that has shown better outcomes for your total knee, total hip and partial knee patients. 1,2,3
It all starts with a CT scan that creates a 3D image of your patient’s unique anatomy. This information you’ve never had before allows you to create your patient’s plan and assess and balance the joint.
Mako Total Knee
A distinct, prospective, consecutive series, single-surgeon study comparing patients undergoing conventional jig-based total knee replacement versus Mako Total Knee surgery (40 patients) concluded that Mako Total Knee with Triathlon was associated with: Less need for opiate analgesics (p<0.001), less time to hospital discharge (26% reduction in LOS), less need for in-patient physical therapy sessions (p<0.001), and less postoperative pain (p<0.001).4
Mako Partial Knee
At minimum 3-year follow-up, Mako Partial Knee patients (n=51) showed no implant failure or implant-related complication or revision surgery, as well as excellent overall patient satisfaction for 96.1% of patients (patients reported very satisfied or satisfied).5
Mako Total Hip
In a cadaveric study, Mako Total Hip was significantly more accurate to plan than manual implantation in reproducing COR and cup orientation.6
Using everything the CT scan helps you to know about your patient, Mako AccuStop haptic technology guides you to cut what’s planned precisely for each patient.1,14,15 For some patients, that means preserving soft tissue; for others, that means saving healthy bone.7,8,9,10
Mako Total Knee
A prospective, consecutive series, single-surgeon study comparing patients undergoing conventional jig-based total knee replacement versus Mako Total Knee surgery (30 patients), concluded that Mako Total Knee with Triathlon was associated with less bone and soft tissue damage (p<0.05).8
Mako Partial Knee
In a single surgeon study comparing consecutive Mako Partial Knee (n=73) vs. manual Oxford uni (n=73), Mako Partial Knee patients demonstrated: reduced post-op pain (p<0.001), decreased analgesia requirements (p<0.001), shorter time to straight leg raise (p<0.001), decreased number of PT sessions (5 vs. 9, p<0.001), improved max knee flexion at discharge (p<0.001), and reduced mean time to hospital discharge (29 hours).11
Mako Total Hip
In a controlled, match-paired study, using acetabular head size as an approximate surrogate measure of acetabular bone resection, results suggested greater preservation of bone stock using Mako Total Hip compared to manual surgery.12

Conclusion
“Patients who underwent TKA using robotic-arm assisted technology had smaller mean differences in PCOR which had been previously shown to correlate with better joint ROM at 1-year following surgery. In addition, these patients were less likely to have values outside of normal Insall-Salvati Index, which meant they may be less likely to develop patella baja, a condition in which the patella would impinge onto the patellar component, potentially leading to restricted flexion and overall ROM.”

Conclusion
In a cadaveric study that compared RA-TKA to manual TKA (M-TKA), “RA-TKA bone cuts were as or more accurate to plan based on nominal median values in 11 out of 12 measurements. RA-TKA bone cuts were more precise to plan in 8 out of 12 measurements. RA-TKA final component positions were as or more accurate to plan based on median values in five out of five measurements. RA-TKA final component positions were more precise to plan in four out of five measurements… When compared with M-TKA, RA-TKA demonstrated more accurate and precise bone cuts and implant positioning to plan.”

Conclusion
CT-guided planning more accurately predicted hip implant cup size when compared to the significant overpredictions of digital and acetate templating. CT-guided templating may also lead to better outcomes due to bone stock preservation from a smaller and more accurate cup size predicted than that of digital and acetate predictions.
