Summary
Routine tourniquet use in knee arthroscopy is not necessary. A prospective randomized trial found no significant differences in operative view, pain, or complications when the tourniquet was not inflated, suggesting its routine use can be discontinued.
Area of Science:
- Orthopaedic Surgery
- Surgical Techniques
Background:
- Tourniquet use in knee arthroscopy is common but associated with increased complication risks.
- Evidence is lacking on the necessity of tourniquets for achieving adequate operative visualization.
Purpose of the Study:
- To determine if tourniquet use is necessary for knee arthroscopy.
- To evaluate the impact of tourniquet inflation on surgical outcomes.
Main Methods:
- Prospective randomized trial involving 109 patients undergoing knee arthroscopy.
- Patients were assigned to either tourniquet inflation or no inflation.
- Outcomes recorded included operative view, duration, pain, analgesic use, and complications.
Main Results:
- No significant differences were observed between the tourniquet and no-tourniquet groups.
- Operative view, procedure duration, pain scores, analgesic requirements, and complication rates were comparable.
- Intraoperative inflation was needed in only 4 patients in the non-inflated group.
Conclusions:
- Knee arthroscopy can be performed adequately without routine tourniquet use.
- The belief that tourniquets are essential for a clear operative view is not supported by this trial.
- Routine tourniquet use for knee arthroscopy should be discontinued.
