title: Cost-benefit comparison: holmium laser versus electrocautery in arthroscopic acromioplasty.
abstract: This prospective study was designed to measure the costs and benefits of using a laser rather than electrocautery for soft tissue resection during arthroscopic shoulder decompression. Forty-nine shoulders with refractory Neer stage II impingement (persistent fibrosis and tendinitis) were divided into 2 groups. The composition of the 2 groups was similar with regard to sex, worker's compensation status, dominant arm involvement, duration of symptoms, and length of conservative treatment. In one group, electrocautery was used to ablate the bursa and periosteum, release the coracoacromial ligament, and maintain hemostasis. In the other group, a laser was used in place of electrocautery. Patients had been evaluated preoperatively with 2 functional scoring systems. The patients were reexamined at 1 week and at 1, 2, 3, 6, and 12 months after surgery. There were no differences between the groups with regard to functional outcome or satisfaction. There was also no difference in terms of estimated blood loss or operative time. However, there was a statistically significant difference in total hospital charges between groups, with the laser group having a 23% higher hospital bill. On the basis of these results, it is concluded that there was no medical benefit to laser-assisted arthroscopic subacromial decompression but there was an increased monetary cost.
