Why Are Knee Replacements Failing Today
Severe degenerative joint disease (DJD) of the knee results in pain, limited function, and a poorer quality of life. Total knee arthroplasty (TKA) is a safe and effective treatment of severe DJD of the knee. Patient satisfaction rates after TKA range from 90% to 95%.[1,2] The high satisfaction rate is dependent on the following factors:
surgical technique; and
postoperative rehabilitation and compliance.
However, TKA can fail, requiring that the patient undergo revision surgery. Annually, 35,000 TKAs are revised worldwide.
The published literature finds the following as the causes for failure of TKA:
Prosthesis fracture; and
At The American Academy of Orthopaedic Surgeons 69th Annual Meeting, held in Dallas, Texas in February 2002, Dr. Peter F. Sharkey, from Philadelphia, Pennsylvania, and his colleagues presented data describing the mechanisms of failure in a series of revision TKAs performed between September 1997 and October 2000. These investigators conducted a retrospective review of 212 consecutive TKAs in 203 patients who underwent total knee revision at the Rothman Institute in Philadelphia, Pennsylvania.
