A product liability lawsuit recently filed against Stryker and Mako Surgical Group in Georgia state court, over problems with a Restoris Multi-Compartmental Knee (MCK) implant, has been removed to the federal court system.

The complaint (PDF) was filed last month by Hazel Perry in the Superior Court of Gwinnett County, alleging that the Mako Restoris MCK system was defective and failed less than a year after it was implanted, resulting in the need for hospitalization and revision surgery.

The manufacturers removed the case to the U.S. District Court for the Northern District of Georgia last week, due to diversity of citizenship between the parties, as Stryker is based in Michigan, Mako, is based in Delaware and Florida and Perry resides in Georgia. Mako is a subsidiary of Stryker.

The Mako Restoris MCK implant was used during a right knee total replacement surgery in October 2015. By May 2016, the lawsuit indicates that the knee implant was loosening and she required revision surgery in June 2016, at which time a surgical pathology report identified the defective knee implant as the cause of the failure.

“As a direct and proximate result of the defective Restoris MCK, Plaintiff has suffer catastrophic injuries and damages, including medical expenses, mental and physical pain and suffering, and loss of consortium,” Perry’s lawsuit states. “In the future, Plaintiff will require therapeutic medical care and other necessary expenses.”

The Mako Restoris Multicompartmental Knee (MCK) is an implant system designed for use as part of robotic-assisted surgery, which is manufactured by Stryker Corp. The Mako robotic arm is used in the procedures to help the surgeon follow a planned path for removing bone and cartilage.

The case comes as a growing number of knee replacement lawsuits have been filed in recent months against the manufacturers of different devices, which plaintiffs allege failed due to design defects.

In addition to this case against Stryker over the Mako knee implant, product liability lawsuits have been filed in recent months over problems with the DePuy Attune Knee,Exactech Optetrak Knee, and Arthrex iBalance Knee.

    I underwent partial knee replacement in both knees on Dec 19, 2016 (a little more than 2 years ago) and expected to be back to normal before now. However, I am still experiencing daily pain which is not limited to just my knees, but goes up into my hips and back. It’s torture to get up from a chair. My knees are often so sore I cannot cross one leg over the other to put on my socks.

    The replacement parts were MAKO RESTORIS MCK Patellofemoral Component and Patella Component –both left and right knees.

    I also had a partial knee replacement that became loose within 2 years and has since required revision surgery and total knee replacement. My original implant was Restoris MCK. I would love to know if anyone has similar stories.

    I had bilateral knew replacements in both knees on July 1, 2016. I returned to the doctor every single month with complaints of knee pain in both knees. The PA Arlene Cavanaugh repeatedly instructed me to up my physical therapy by doing more and increasing level of difficulty. On another visit she told me “Sometimes it takes more time”. On another visit she told me “some people just get to a certain point of recovery.” She did not refer me back to the surgeon R. Tabbador. Nor do I believe she consulted with him about my case. I eventually had to I sista on seeing him. With my daily life being severely impacted I insisted that he request an MRI. He did so reluctantly telling me that it wouldn’t show anything. The test revealed that the left knee had failed and I needed a full replacement left knee. Given the sub par care of this doctor I sought a different doctor for consultation with the results of that MRI. That left knee was replaced in August 2017. Still continuing with pain in the right knee I was incapacitated in my daily life and eventually unable to continue with my job, forcing retirement. Though the right pain has somewhat subsided with the help of medication, I am told after a scan that the knee has come loose due to failure of the glue and I will be required to totally replace this right knee. I would like to know if I have any claim to this recall.
