Continuous cold therapy after total knee arthroplasty (TKA) showed a modest decrease in blood loss but did not significantly impact narcotic use, transfusion needs, or hospital stay. Therefore, its routine recommendation for all TKA patients is not supported.

Area of Science:

  • Orthopedic Surgery
  • Postoperative Care

Background:

  • Total knee arthroplasty (TKA) is a common procedure.
  • Effective postoperative management is crucial for patient recovery.
  • The role of continuous cold therapy in TKA outcomes requires further investigation.

Purpose of the Study:

  • To evaluate the effectiveness of continuous cold therapy in reducing postoperative blood loss and improving other outcomes after total knee arthroplasty (TKA).

Main Methods:

  • A retrospective study of 52 patients undergoing TKA.
  • Comparison between a group receiving continuous cold therapy (33 patients) and a control group (19 patients).
  • Cold therapy involved 42°F water circulation for an average of 3 days postoperatively.

Main Results:

  • Patients receiving continuous cold therapy experienced an average decrease of 200 cc in postoperative blood loss.
  • No significant differences were observed in narcotic use, transfusion requirements, or hospital length of stay between the groups.
  • Postoperative swelling and range of motion data were inconsistently recorded and not analyzed for significance.

Conclusions:

  • Continuous cold therapy may reduce blood loss following TKA, but the clinical significance is uncertain.
  • The current evidence does not support the routine recommendation or justify the additional cost of continuous cold therapy for all TKA patients.
  • Further research with consistent outcome recording is needed to fully ascertain the benefits of cold therapy in TKA.
