    Summary
    This summary is machine-generated.

    Total condylar knee prostheses show excellent long-term results, with 87.5% functioning well after ten years. Proper surgical technique and patient selection are key for successful knee replacement outcomes.

    Area of Science:

    • Orthopedic surgery
    • Biomaterials science

    Background:

    • Total condylar prostheses are widely used for knee replacement surgery.
    • Long-term survival and performance data are crucial for evaluating implant efficacy.

    Purpose of the Study:

    • To assess the long-term (10+ years) functional outcomes and survival rates of total condylar knee prostheses.
    • To identify factors influencing the success or failure of these implants.

    Main Methods:

    • A retrospective follow-up study of forty knees with total condylar prostheses.
    • Evaluation of functional outcomes, radiographic changes, and reasons for failure over a minimum of ten years.

    Main Results:

    • 87.5% of knee arthroplasties (35 out of 40) demonstrated satisfactory function after ten years.

  • Five failures occurred: one due to infection, four related to improper selection or technical issues.
  • No component loosening or complete radiolucent lines were observed, indicating good fixation.

    • Conclusions:

    • Conventional polymethyl methacrylate cement fixation is adequate for knee arthroplasty when performed correctly.
    • Proper surgical technique and patient selection are paramount for successful long-term outcomes.
    • The absence of progressive radiologic changes suggests a considerable life expectancy for knee arthroplasties.
