The benefits of a MAKOplasty®partial knee replacement*
- Extremely high accuracy of anatomical placement
- More natural knee motion
- Much quicker recovery
- All 4 stabilizing ligaments remain intact (ACL, PCL, MCL, LCL)
- No muscles are cut
- Healthy articular cartilage preserved
- Small incisions
- No staples to remove
- Less pain
- Minimal blood loss
- Extremely low blood clot risk
- No in-patient rehab required
- Much shorter outpatient physical therapy required
**With a partial knee replacement, the procedure is so minimal that in most cases, patients walk out of the surgery center 1½ hours after surgery and begin physical therapy the next day.*
The traditional Total Knee Replacement (TKR) is designed to allow patients to walk, but not to run or play sports.* The modern day total knee replacement removes the major ligaments in the knee (the ACL and PCL for example). Recent studies have demonstrated no functional limitations during swimming and biking; however, significant limitations were noted during more strenuous activities such as kneeling, squatting, moving laterally, turning and cutting, carrying loads, stretching, leg strengthening, tennis, dancing, gardening, and even sexual activity.*
In contrast, during a Partial Knee Replacement (PKR), only the arthritic region of the knee is resurfaced, preserving the central ligaments of the knee (the ACL and PCL) as well as near normal knee motion. Historically, Partial Knee Replacement was nearly abandoned over 40 years ago due to concerns about durability. Early on, the materials and fixation were not developed enough for a partial solution to provide long lasting pain relief. However, over the past quarter century, the material and fixation improvements pioneered for total knee replacement have translated to durable solutions for partial replacements as well.*
Partial knee replacement is not possible for all patients with arthritis. It is indicated when the arthritic condition is fairly localized. Both partial and total knee replacement can provide durable pain relief and improve function in patients with knee arthritis. Partial knee replacement may only be possible in 10-30% of patients.*
The Mako Robotic Arm
The use of the robotic arm with partial knee replacement has revolutionized the procedure and now provides the durability that patients seek in addition to the benefits of faster recovery and improved functionality.* The robotic procedure is twofold:
First – A CT scan is taken of your knee to produce a 3D virtual model of your specific anatomy. This virtual model is uploaded into the Mako Robotic Arm software and used to create your personalized pre-operative planning.
Second – During your procedure, your surgeon will utilize the robotic arm to execute your specific pre-operative plan with the flexibility to make adjustments on the fly when necessary. The Mako system guides the surgeon utilizing the 3D virtual model loaded into the system. This preserves healthy bone and allows for perfect alignment and fixation, which was not possible 20 years ago without the assistance of the robot.
After Surgery – Your surgeon, nurses and physical therapists will set goals with you to get you back to activity as soon as possible. They will closely monitor your progress and your surgeon may review an x-ray of your new partial knee with you.
