Arthroscopic subacromial decompression with and without the Holmium:YAG-laser. A prospective comparative study
1Department of Orthopaedic Surgery, Balgrist Hospital, University of Zürich, Switzerland.
Summary
Laser-assisted arthroscopic subacromial decompression (ASD) offers superior outcomes for impingement syndrome. Patients experienced reduced pain and improved shoulder function faster compared to conventional methods.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
Background:
- Shoulder impingement syndrome is a common cause of shoulder pain and dysfunction.
- Conventional arthroscopic subacromial decompression (ASD) utilizes shavers and electrocautery.
Purpose of the Study:
- To evaluate and compare the outcomes of laser-assisted ASD versus conventional arthroscopic ASD.
- To assess subjective, objective, and functional results in patients with impingement syndrome.
Main Methods:
- Prospective study of 52 patients with stage II/III impingement syndrome.
- Two groups: conventional arthroscopic surgery (group S, n=18) and Holmium:YAG-laser ASD (group L, n=34).
- Constant score assessed preoperatively and up to 1 year postoperatively.
Main Results:
- Group L showed significantly better postoperative Constant scores (79.8 vs. 68.7).
- Laser group experienced faster improvement in pain, night pain, and movement at 1 and 6 weeks.
- Group L demonstrated significantly better abduction power (P < .05) and quicker return to full range of motion.
Conclusions:
- Laser-assisted ASD is a safe and effective alternative to conventional arthroscopic decompression.
- The laser technique leads to superior functional outcomes, reduced pain, and faster recovery.
