Knee arthroplasty saw blades generate excessive heat, potentially causing bone necrosis and harming prosthetic fixation, especially for bone ingrowth implants. Saline irrigation offers minimal temperature reduction during surgery.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Surgical Technology

Background:

  • Knee arthroplasty involves bone cutting, a process that generates heat.
  • Elevated temperatures can negatively impact bone viability and implant osseointegration.
  • Understanding thermal effects is crucial for optimizing surgical outcomes.

Purpose of the Study:

  • To quantify temperatures generated in the tibia and saw blade during knee arthroplasty.
  • To assess the impact of irrigation on thermal profiles.
  • To evaluate the thermal effects of cement curing on the bone-cement interface.

Main Methods:

  • Temperature monitoring of the saw blade and tibia during 30 knee arthroplasty procedures.
  • Measurement of bone temperatures at 2 mm and 3 mm below the cutting surface.

Related Experiment Videos

  • Recording temperatures during the cement-curing phase at the bone-cement interface.

    • Main Results:

    • Median maximum saw blade temperature reached 68°C (45-100°C).
    • Tibia temperatures were recorded at 47°C (2 mm depth) and 42°C (3 mm depth).
    • Physiologic saline irrigation had minimal effect; cement curing reached 37°C (31-50°C).

    Conclusions:

    • Surgical cutting temperatures exceed the threshold for bone necrosis, potentially compromising prosthetic fixation.
    • The heat generated may adversely affect bone ingrowth fixation.
    • Further strategies are needed to mitigate thermal damage during knee arthroplasty.
