Short versus standard duration tourniquet use during Total Knee Replacement: A pilot study

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Clinical Research

Background:

• Tourniquet application is standard in knee replacement surgery.
• Prolonged tourniquet use may lead to complications like swelling and soft tissue issues.

Purpose of the Study:

• To evaluate the impact of short-duration tourniquet application versus standard use on surgical outcomes.
• To assess effects on surgical time, post-operative swelling, pain, rehabilitation, and complications.

Main Methods:

• Prospective, randomized controlled trial.
• Sixty patients undergoing knee replacement surgery were randomized into two groups.
• One group received short-duration tourniquet application (cementation only), the other standard duration.

Main Results:

• No significant differences in surgical time or post-operative pain between groups.
• Short-duration tourniquet group showed significantly reduced thigh swelling (p<0.01).
• Higher rates of soft tissue complications observed in the standard duration group.

Conclusions:

• Applying tourniquets for a shorter duration, specifically during cementation, effectively reduces post-operative thigh swelling.
• This approach also lowers the incidence of soft tissue complications compared to standard prolonged tourniquet use.
• Short-duration tourniquet use is a viable alternative for knee replacement procedures.
