Outcomes after arthroscopic revision rotator cuff repair

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Musculoskeletal Research

Background:

• Limited data exists on outcomes following arthroscopic revision rotator cuff repair compared to open procedures.
• Previous studies have primarily focused on open revision rotator cuff repair outcomes.

Purpose of the Study:

• To evaluate the effectiveness of arthroscopic revision rotator cuff repair in improving shoulder function and pain.
• To identify prognostic factors associated with successful outcomes and potential failure after arthroscopic revision rotator cuff repair.

Main Methods:

• A case series design (Level of evidence, 4) was employed.
• Demographic data, prior surgery history, and tear characteristics were collected via chart review.
• Preoperative and postoperative measurements of shoulder strength, range of motion, American Shoulder and Elbow Surgeons (ASES) scores, Simple Shoulder Test (SST), and visual analog pain scale (VAS) were compared using paired t tests.

Main Results:

• Fifty-four patients underwent arthroscopic revision rotator cuff repair with a mean follow-up of 31.1 months.
• Significant improvements were observed in ASES scores (43.8 to 68.1), SST scores (3.56 to 7.5), VAS pain scores (5.17 to 2.75), and forward elevation (121.0 to 136 degrees).
• More than one prior ipsilateral shoulder surgery was linked to revision failure, while female gender and preoperative abduction less than 90 degrees were associated with lower ASES scores postoperatively.

Conclusions:

• Arthroscopic revision rotator cuff repair offers a viable treatment option, yielding significant improvements in pain relief and shoulder function, even after prior open repairs.
• While effective, outcomes are not universally optimal.
• Female patients and those with a history of multiple ipsilateral shoulder surgeries face an elevated risk of suboptimal results.
