title: Time and cost savings in arthroscopic subacromial decompression: the use of bipolar versus monopolar radiofrequency.
abstract: There is currently an increased interest in the use of electro surgery in arthroscopy. Since the introduction of the bipolar arthroscopic radiofrequency (RF) wand, it has started to replace the classic Bovie monopolar probe on the assumption that the new technology provides multifunctional devices, combining both tissue removal and haemostasis into one instrument. The more efficient tissue ablation and precise haemostasis achieved with these instruments should result in a significant reduction in the operative time and cost. We ran a prospective comparative randomised study to test this hypothesis. Forty patients underwent arthroscopic subacromial decompression, randomised into two groups. The group treated with bipolar RF was associated with an average operative time saving of 8 min (P < 0.0001) and an average cost saving of pound 83 (euro 111) per case (P < 0.003), compared to monopolar RF. Bipolar RF is the instrument of choice in arthroscopic shoulder surgery, as it saves time and money.
