Revision Total Knee Arthroplasty

    Summary

    Background: Revision of total knee arthroplasties are performed with increasing frequency due to the increasing numbers of primary arthroplasties.

    Objectives: To retrospectively analyze 71 patients who underwent 78 revision total knee arthroplasties during the years 1991 to 1999

    Methods: We evaluated the revised knees using the Knee Society Clinical Rating System after an average follow-up period of 3 years and 9 months (2–10 years). The indications for revision included pain and instability, deep infection of the joint, complaints linked to the patella, or post-trauma to the operated knee.

    Results: The average knee score (evaluation of the knee joint itself) calculated after the revision was 74.5. The results on the knee score were excellent (>85) in 48% of patients and poor (<60) in 22%. The functional results (patients’ ability to walk and climb stairs) were only 48.3.

    Conclusion: Although the revision of total knee replacements is known to be problematic, most patients show good results on knee examination, and reasonable functional results given the factors involved.
