Comparative Evaluation of Early Functional Recovery and Return to Activity Following Mini-Open Versus Arthroscopic Supraspinatus Repair

Abstract

Background: Supraspinatus tendon tears represent a significant subset of rotator cuff injuries, often necessitating surgical repair when conservative treatment fails. Two commonly employed techniques—arthroscopic and mini-open repairs—offer distinct advantages. This study aimed to compare the short-term functional outcomes and return to activity following these two surgical methods.

Methods: A prospective, comparative study was conducted on 60 patients with isolated full-thickness supraspinatus tears treated either with mini-open (n=30) or arthroscopic repair (n=30). All patients were assessed preoperatively and postoperatively at 6 weeks, 3 months, and 6 months using the Visual Analog Scale (VAS), American Shoulder and Elbow Surgeons (ASES) Score, Constant-Murley Score, range of motion (ROM), and time to return to activity. Statistical analysis was performed using independent t-tests with a significance threshold of p<0.05.

Results: Both groups showed statistically significant improvements in pain scores and functional outcomes over time. The arthroscopic group demonstrated superior early outcomes, including lower VAS scores (p=0.03 at 6 weeks, p=0.01 at 3 months) and higher ASES scores (p=0.02 at 6 weeks, p=0.04 at 3 months). At 6 months, there was no significant difference in ROM or final scores between groups. The mean time to return to activity was significantly shorter in the arthroscopic group (13.4 ± 1.9 weeks) compared to the mini-open group (15.2 ± 2.4 weeks; p=0.01).

Conclusion: Both arthroscopic and mini-open techniques effectively restore shoulder function and relieve pain in patients with supraspinatus tears. However, arthroscopic repair offers faster early recovery and quicker return to activity, making it a preferable option for patients seeking minimal downtime. Mini-open repair remains a viable alternative with similar long-term results.
