Your Partial Knee Surgery - UniSpacer™
Using special UniSpacer templates, your doctor can determine which size may be best for you before the surgery even begins.
Arthroscopic Debridement & Resection of the Meniscus.
This part of the procedure is similar to a standard “scope” that many patients may have already undergone. Your doctor will make a few small incisions in your knee and insert a small tube with a light and a camera on the tip. The camera projects images of the inside of your knee onto a television screen, guiding the surgeon as he or she maneuvers the instrument.
During the arthroscopy, your doctor will look around the inside of your knee to make sure that you are indeed a candidate for the UniSpacer. If you are, your doctor will remove your meniscus and clean up any excess debris during this stage. Also, a length measurement will be taken to verify which size implant to use.
This is the part of the procedure where your doctor will make a standard cut to open up your knee. The incision is typically 2-3 inches long.
The body sometimes forms small bony growths called osteophytes to try and compensate for an unbalanced joint. Your knee may have some of these osteophytes. Your doctor will be able to recognize and remove them before inserting the UniSpacer
Your doctor will use a thickness gauge to help further determine what size UniSpacer may work for your knee.
Tibial & Femoral Cartilage Preparation
Before inserting the UniSpacer, your knee will require some preparation. In order to provide a smooth surface for the UniSpacer to interface with the bones in your knee, your doctor may have to level out the rough spots by removing or reshaping cartilage. How much preparation is needed is particular to each individual’s knee.
Before inserting the actual UniSpacer implant, an implant trial will be used. This trial simulates the real implant, which allows your doctor to evaluate how the implant will work in your knee.
Another tool to help your doctor evaluate how the UniSpacer will work in your knee is the Fluoroscope. It works like an x-ray, and gives a real-time image of your knee with the implant trial inserted. Your doctor will move your knee through multiple series of extensions and flexions to judge the sizing and motion of the device.
After evaluating the implant trial for correct sizing and function, your doctor will then replace it with the actual UniSpacer implant.
