Unlike traditional knee replacement surgeries, Mako SmartRobotics Partial Knee Replacement (Mako Partial Knee) accurately executes the removal and replacement of a single damaged joint surface (the medial, lateral, or patellofemoral part) with robotic arms without having to wait until the fourth stage of severe degeneration, retaining the healthy bone parts and tendons, hence reducing the unnecessary invasive damage generated in traditional surgeries.

【Main indications】
Targeted at patients with mild to moderate knee osteoarthritis, executing precise removal and localization in accordance with the damaged part of the knee (the medial, lateral, or patellofemoral part), installing perfectly-fitting thin prosthetic material onto the damaged articular surface to reconstruct prosthetic knees, dissolving early stage pain and halting deterioration for the patients without having to wait until the fourth stage of severe degeneration.

【Surgical procedures】

1.Tailored pre-surgery planning
The incorporation of 3D modeling of the hip joints with CT images (as shown below) and pre-surgery planning conducted through Mako® robotic arms can determine the most suitable size and positioning of the knee prosthesis for patients.

2.Real-time data provided during surgery
During the surgery, real-time 3D images of the patient’s bones and the kinetic parameters of the joints are provided to enable the orthopedic surgeon to immediately adjust or check the position of the prosthesis, performing the surgery completely according to the condition of the patient’s knee and ensuring replacements with errors less than 1° and 1 mm.

3.Flexible post-surgery knees
Precise positioning of the implants to reduce post-surgery stiffness, enabling easier rehabilitation and a speedy return to normal life; not only a natural range of joint motion can be achieved, but also the life span of the knee joint can be prolonged.

【Features of the surgery】

1. Repairs damaged articular cartilage surfaces

2. Retains healthy bone structures and cruciate ligaments 

3. Tailored and precise bone removal

4. Small wounds and fast recoveries

5. Restores normal joint functions and natural gaits
