Complications Caused by Knee Replacement Devices

Any type of surgery, including knee replacement procedures have some side effects.  Most patients experience only minor side effects including mild to moderate pain, swelling, and inflammation which will go away after a period of time.

In some cases however, patients experience side effects or adverse events that are more serious and warrant medical attention.  Some of these patients will require knee revision surgery.

Serious adverse events related to knee replacement surgery may include:

  • Debilitating pain or inflammation
  • Infection of the knee which may become body-wide
  • Nerve or blood vessel damage surrounding the knee device
  • Bone or joint tissue damage
  • Loosening of the replacement device, resulting in immobility
  • Lower leg blood clot development (deep vein thrombosis or DVT)

These serious adverse events may require the patient have a revision surgery or second surgery to remove and replace the original joint device.  Second surgeries are generally much more invasive, painful and will likely require a longer recovery period.

Issues noted in recalls commonly included:

  • Sterility issues
  • Mislabeling issues including components and metal content
  • Missing components or features
  • Improper assembly guides
  • Faulty design of implant tools or manufacturing
  • Implant loosening
  • Other manufacturing issues

Implants are recalled because issues related to design or manufacturing may pose a significant risk to patients.  Any serious adverse event caused by a faulty knee replacement device may warrant an invasive knee revision surgery.
