Successful long-term results seen after arthroscopic subacromial decompression for impingement syndrome
Patients with impingement syndrome did well 20 years after their index arthroscopic subacromial decompression, including acromioplasty, resection of the coracoacromial ligament and coplaning, according to results.
Researchers identified 95 patients with subacromial impingement syndrome with or without a rotator cuff tear and with or without calcific deposits who underwent arthroscopic subacromial decompression, including acromioplasty, resection of the coracoacromial ligament and coplaning without cuff repair, and had a mean follow-up of 19.9 years. Researchers used the Constant score to assess shoulder function.
Results showed 14.7% of patients underwent revision surgery 20 years after the index procedure, with patients with impingement syndrome and tendinitis calcarea undergoing significantly more revisions than patients with impingement. Compared with patients with partial-thickness tears and those with isolated impingement, researchers found worse relative-Constant scores among patients with full-thickness tears and secondary arthrosis.
According to results, 78.8% of all cases showed successful results, with the combined endpoint of revision surgery and relative-Constant score 20 years after arthroscopic subacromial decompression. Overall, researchers found all patients with isolated impingement syndrome achieved successful results.
Among patients with partial-thickness tears, 70.6% had a satisfactory benefit, researchers found. Results also showed 70.6% of patients with either full-thickness tears or full-thickness tears and secondary arthrosis had successful operations, while patients with tendinitis calcarea had a success rate of 65.2%. – by Casey Tingle
