A Zimmer Knee lawsuit has been filed by Angela Coleman in Michigan Federal Court. Ms. Coleman underwent knee replacement surgery in 2007 and was given a Zimmer knee implant. The lawsuit claims that the plaintiff has suffered from severe and debilitating pain due to the defective design of the joint implant. The lawsuit also alleges that the artificial knee joint became loose and its poor design has led her to go through a revision or corrective surgery. In addition to suffering from unnecessary pain and emotional stress, she has also incurred additional medical expenses.

The Zimmer knee implants are used in knee replacement surgeries to give patients relief from problems of knee joints. Zimmer offers a minimally invasive solution through many Zimmer knee components. They have been developed as per requirements for minimally invasive surgery. Zimmer MIS Solutions are designed to facilitate implantation through a smaller incision so that muscles and tendons around the knee are not damaged. These knee components are claimed to give patients a relaxed and better life.

The Zimmer NextGen CR-Flex Porous Femoral Component is one of the knee implant component from Zimmer. It is a non-cement piece, which is attached to the bottom of the thighbone. It is linked with several implant problems and a high rate of implants failure.

The Zimmer NexGen CR-Flex is different from other implants as it is a non-cement implant, which is attached to the thighbone. Many patients have complained of problems after going through Zimmer knee implant. Following problems are the most common problems experienced by patients having Zimmer knee implant.

  • Knee Replacement Failure
  • Loosening of Replacement Knees
  • Other Knee Complications and Knee Pain

All these problems restrict patients from leading an active day-to-day life. If a patient having Zimmer knee implant experiences knee stiffness, knee pain, limping, decreased range of motion in the joint and difficulty putting weight on the knee, it may be sign of loosening of implant.

Some patients may need revision surgery after joint replacement, but Coleman’s Zimmer Knee lawsuit attorney blamed the faulty design of the joint implant for revision surgery of her only a year after having the company’s NexGen Knee artificial joint. It also claims that the joint implant “is defective in its design or formulation in that it is not reasonably fit, suitable or safe for its intended purpose.”

This lawsuit cites studies conducted on loosening of the artificial knee joints. A Korean study revealed that more than half of all patients who received knee implants similar to the NexGen Knee joint require additional surgery.  The study published in the Journal of Bone and Joint Surgery also stated that nearly 40 percent of knee replacement patients got their knee joints had come loose within two years of the first surgery. The lawyer said that this was due to the faulty design of the implant.

The lawsuit also blamed Zimmer Inc. for not providing adequate warning regarding the implant failure or loosening on the label of the product. It blamed that company understated the risks associated with the artificial joint that it could loosen and cause severe pain to the patient. The lawsuit is seeking for additional medical expenses and compensation for pain and suffering of the plaintiff.
