Knee replacement surgery is meant to relieve pain and improve mobility, but when surgical tools used during the procedure are defective, the outcome can be very different. That’s what happened with the Stryker ShapeMatch Cutting Guide, a device once used to assist surgeons in total knee replacement surgeries. Instead of improving accuracy, flaws in its software led to surgical errors, and in many cases, long-term complications for patients.
The device was pulled from the market following a Class I recall by the U.S. Food and Drug Administration (FDA). The Food and Drug Administration (FDA) has the most serious type of recall.
If you had knee replacement surgery between 2011 and 2013 and are now experiencing pain, instability, or need a second surgery, this recall may apply to you. Understanding the risks and your legal options is the first step toward getting the care and answers you deserve.
The ShapeMatch Cutting Guides were single-use, disposable surgical tools designed to assist surgeons in aligning knee implant components during total knee replacement surgery. These guides were customized for each patient using pre-operative imaging and an online planning application.
However, software defects in the system caused mismatches between the surgical plan and the cutting guide that was actually produced.
The parameters of the manufactured cutting guides may not meet the surgeon’s pre-operative planning parameters entered via a web application.
This meant the depth of cuts and angles used during surgery often did not match the surgeon’s intended plan, which could result in improper alignment of the implant.
In April 2013, the U.S. Food and Drug Administration (FDA) classified this as a Class I recall, the most serious type of recall.
The FDA classified this as a Class I recall, meaning the use of this device may cause serious injuries or death.

As of the recall date, the FDA had received 44 reports of device-related incidents, including three cases involving medically reversible injuries.

| January 2013 | Product notification sent to branches, surgeons, and hospitals |
