What is the Stryker Triathlon?
Stryker Orthopedics manufactures the Triathlon Knee System, a total knee replacement that has been sold in the United States since 2005. Its unique “single radius” design allows the knee to pivot in a circular motion rather than a “hinge” motion.
Stryker Triathlon and the ShapeMatch Cutting Guide
In April 2013, Stryker announced a Class 1 recall of the Stryker ShapeMatch Cutting Guide after receiving 44 reports of incidents involving malfunctions, improper bone cuts, and/or serious patient injuries. The ShapeMatch Cutting Guide is used exclusively with the Triathlon Knee System.
What is the problem?
When a surgeon is fitting a patient with a Triathlon knee replacement, the ShapeMatch Cutting Guide is used to help a surgeon select the best-fitting components and mark the patient’s bone before making cuts. Accuracy is extremely important.
Unfortunately, software defects with the Cutting Guide may result in bone cuts that are wider than they should be, which may result in a poorly-fitting Triathlon Knee System. Serious adverse events may include joint instability, bone fracture, chronic pain, limited mobility, and need for revision surgery. According to the FDA warning:
“The parameters of the manufactured cutting guides may not meet the surgeon’s pre-operative planning parameters entered via the web application. Additionally, Stryker Orthopaedics determined that another software defect resulted in the displayed parameters (e.g. depth of resection, angle of cut) not matching the cutting guides produced.”
Stryker Triathlon Recall
Stryker has not recalled the Triathlon knee replacement. However, they have received 44 reports of incidents and injuries (41 “malfunctions” and 3 “temporary” reversible injuries) associated with the ShapeMatch Cutting Guide, which was only used with the Triathlon knee replacement. If you had knee surgery between May 2011 and November 2012 and you are now having problems, you may qualify to file a lawsuit.
