Brief Summary

We will assess the temperatures achieved during bone cutting in total knee replacements, comparing burr and saw techniques. Our study involves recruiting 20 patients from East Suffolk and North Essex NHS Foundation Trust (Colchester site). Patients will be recruited from the orthopaedic outpatient clinic, with 10 undergoing Robotic total knee arthroplasty (burr cutting) and 10 undergoing conventional total knee arthroplasty (saw cutting). Temperatures will be measured using a visual infrared thermometer placed outside the surgical field while a consultant surgeon performs the procedure. Importantly, these temperature recordings will have no impact on which treatment the patient received as the standard of care.

Conditions

Total Knee Arthroplasty; Total Knee Replacement

Keywords

Osteoarthritis

Outcome Measures

Primary Outcomes (1)

• The measure of temperature generated by burr and saw cutting devices during total knee arthroplasty.

  Temperature will be measured in degrees centigrade

  During surgery

Secondary Outcomes (1)

• Duration of temperature above 47 degrees centigrade in burr and saw cutting groups.

  During surgery.

Study Arms (2)

Robotic Total Knee Arthroplasty

With burr cutting
