For the past few decades, surgical outcomes involving total knee replacements have greatly improved. While past generations would often put off seeing a doctor for knee pain, today's active adults find relief with total knee replacement surgery. There are numerous noninvasive treatments that are often exhausted prior to resorting to surgical intervention including physical therapy, medication to reduce pain and inflammation and using an assistive device (e.g., a cane).

Obesity also increases the risk of osteoarthritis in the knee because it increases pressure on the knee joint. Lack of physical activity can also create a loss of muscle that surrounds and protects the knee joint. Accordingly, many find relief through exercise and weight loss to help reduce symptoms of knee pain.

When surgical intervention becomes the only option, many find comfort in that total knee replacement surgeries have far more consistent outcomes thanks to new techniques, technology and materials. In fact, U.S. doctors now perform approximately 700,000 knee replacement surgeries each year.

Some interesting statistics concerning knee replacement surgeries include:

  • Almost 9 out of 10 knee replacement surgeries are total knee replacements
  • The majority of knee replacement surgeries are done in women
  • 95% of patients today report that they are happy with their total knee replacement
  • 90% of knee replacements last 10 years and 80% last 20 years with relatively few reported problems by patients
  • Most knee replacement patients are up and walking within a few days after surgery 


The DePuy knee replacement lawyer Dean Goetz is currently investigating cases where patients were implanted with the DePuy Synthes Attune® Knee System – a total knee replacement solution. Thus far, numerous cases of premature failure of the device have been reported to the FDA's adverse event reporting system. Current clients report early failure of the device, sometimes within just months of their surgery.

The DePuy Synthes Attune® Knee System was first approved by the FDA in 2013 and continues to be implanted until today. The most common complaint our firm has encountered are patients who have a revision surgery where they were informed that the tibial plate loosened or was not properly fixated to the tibia. This, unfortunately, causes extreme pain, swelling and other complications that can result in the need for a revision surgery.

Recently, a study called "Unusually High Rate of Early Failure of Tibial Component in ATTUNE Total Knee Arthroplasty System at Implant-Cement Interface" was published in the Journal of Knee Surgery (Thieme Medical Publishers, Inc.). The study followed 15 cases with an average age of 61 years for the patients. The patients all presented with pain when bearing weight and a decreased range of motion within 2 years after surgery. X-rays and other radiologic studies only showed loosening of the tibial component in 2 of the 15 knees; however, surgical intervention showed loosening in ALL of the cases. Put differently, an x-ray or other radiologic study may not show whether your DePuy Synthes Attune® Knee System is actually loose and a surgeon may have to investigate through another surgery.   As a result, all of the patients in the study had to undergo a revision surgery to address the issue.
