Summary
Tourniquet use in total knee arthroplasty is safe. While knee flexion was slightly better without a tourniquet at one week, outcomes were similar long-term, with no increased risks.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Tourniquets are commonly used in total knee arthroplasty (TKA) to reduce blood loss and improve visualization.
- The impact of tourniquet use on functional outcomes and complications in TKA remains a subject of clinical debate.
Purpose of the Study:
- To prospectively evaluate the influence of tourniquet application on functional recovery and safety after TKA.
Main Methods:
- A prospective, randomized study involving 77 patients undergoing TKA.
- Patients were divided into two groups: one with tourniquet use and one without.
- Key outcomes including knee flexion, surgical time, pain, and complications were assessed.
Main Results:
- A statistically significant improvement in knee flexion was observed at one week in the no-tourniquet group (p=0.03).
- However, knee range of motion was comparable between groups at six weeks and four months post-surgery.
- No significant differences were found in surgical duration, pain, analgesia requirements, drainage volume, swelling, wound complications, or deep-venous thrombosis incidence.
Conclusions:
- The use of a tourniquet in TKA is a safe practice.
- Current surgical protocols involving tourniquets can be safely continued without compromising patient outcomes.
