Summary
Using an optimized tourniquet (TNQ) in total knee arthroplasty showed no significant differences in clinical outcomes or complications compared to not using a TNQ. This approach offers a clean surgical field without increasing risks.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Tourniquet use in knee arthroplasty remains controversial.
- Optimized tourniquet protocols aim to balance surgical field benefits with potential complications.
Purpose of the Study:
- To compare clinical outcomes and complications between total knee arthroplasty with and without an optimized tourniquet protocol.
- To evaluate the efficacy of an optimized tourniquet in primary total knee arthroplasty.
Main Methods:
- Prospective evaluation of 127 knee osteoarthritis patients undergoing total knee arthroplasty.
- Randomization into "without TNQ" and "optimized TNQ" groups.
- Comparison of surgical timing, blood loss, pain, edema, ROM, functional scores, and complications.
Main Results:
- No significant differences observed in surgical timing, blood loss, pain, edema, range of motion, or functional scores between groups.
- Postoperative complications were similar in both the "without TNQ" and "optimized TNQ" groups.
Conclusions:
- An optimized tourniquet protocol in primary total knee arthroplasty yields similar clinical results to surgery without a tourniquet.
- Tourniquet use provides a clean surgical field without increasing procedure-related comorbidities or complications.
