Arthroscopic versus open acromioplasty: a meta-analysis

Area of Science:

• Orthopaedic Surgery
• Minimally Invasive Procedures
• Surgical Outcomes Research

Background:

• Controversy exists regarding the efficacy of arthroscopic versus open acromioplasty.
• Previous studies have yielded conflicting results on patient outcomes.
• A comprehensive evaluation is needed to clarify treatment effects.

Purpose of the Study:

• To compare the clinical outcomes of arthroscopic acromioplasty with open acromioplasty.
• To evaluate differences in recovery time, hospital stay, and postoperative morbidity.
• To provide evidence-based guidance for surgical technique selection.

Main Methods:

• Meta-analysis of English language literature sourced from PubMed and orthopaedic meeting proceedings (2000-2007).
• Inclusion of nine studies directly comparing arthroscopic and open acromioplasty with a minimum 1-year follow-up.
• Analysis focused on 1-year clinical outcomes, including objective scores, hospital stay, return to work, operative time, and complications.

Main Results:

• No significant differences in overall clinical outcomes or complication rates between arthroscopic and open acromioplasty.
• Open acromioplasty was associated with significantly longer hospital stays (2.3 days longer).
• Patients undergoing open acromioplasty experienced a longer time to return to work (65.1 days vs. 48.6 days).

Conclusions:

• Arthroscopic and open acromioplasty yield equivalent long-term clinical outcomes.
• Arthroscopic acromioplasty demonstrates advantages in reduced hospital inpatient days.
• The arthroscopic approach facilitates a faster return to work compared to the open technique.
