A novel cement compression device (CCD) significantly improves cement penetration in total knee arthroplasty (TKA) without increasing operating time. This enhanced fixation may reduce aseptic loosening risks.

Area of Science:

  • Orthopedic surgery
  • Biomaterials engineering
  • Medical imaging

Background:

  • Optimal tibial component fixation is critical for preventing aseptic loosening in total knee arthroplasty (TKA).
  • Current cement application techniques often fail to achieve the desired 3-4 mm cement penetration depth.
  • A cement compression device (CCD) was developed to enhance cement penetration and distribution.

Purpose of the Study:

  • To evaluate the efficacy of a cement compression device (CCD) in improving cement penetration and distribution in TKA.
  • To compare cement penetration achieved with the CCD versus the traditional finger-packing technique.
  • To assess the impact of the CCD on surgical operating time.

Main Methods:

  • A randomized controlled trial comparing the finger-packing technique with the CCD for cement application in TKA.

  • Postoperative CT scans were used to quantify the percentage of cemented surface (PCS) per quadrant up to 7 mm depth.
  • MATLAB was utilized for image analysis to differentiate bone, cement, and prosthesis based on Hounsfield units.

    • Main Results:

    • The CCD group showed significantly higher PCS in the anterolateral (72% vs 54%), posterolateral (46% vs 34%), and posteromedial (39% vs 28%) quadrants compared to the finger-packing group.
    • No significant difference in PCS was found in the anteromedial quadrant.
    • Operating time was comparable between the finger-packing (66 min) and CCD (68 min) groups.

    Conclusions:

    • The cement compression device (CCD) effectively improves cement penetration and distribution in the proximal tibia during TKA.
    • The CCD achieves optimal cement depth (3-7 mm) without prolonging surgical procedure time.
    • This technology holds promise for enhancing tibial component fixation and potentially reducing aseptic loosening rates in TKA.
