Objective: Polydeoxyribonucleotide as adenosine receptor (A) agonist has been used in plastic surgery and dermatology related to its regenerative property. The aim of this pilot study is to evaluate the safety and efficacy of polydeoxynucleotide injection in patients with rotator cuff tears by a variety of outcomes including pain, disability, physical performance test, and ultrasonography (US).

Methods: Seventeen patients (9 men, 8 women, age: 57.

Unlabelled: Posterosuperior impingement (PSI) is an underdiagnosed cause of posterior shoulder pain and should be differentiated from classic and external impingement. PSI involves the internal impingement of soft tissues, including the undersurface of the rotator cuff against the posterosuperior labrum when the arm is brought into abduction and external rotation (ABER). Ultrasonography (US) can be useful in the assessment of PSI because of its high resolution and ability to perform during dynamic maneuvers in ABER.

Article Synopsis
  • - This study compared the outcomes of conservative treatment versus arthroscopic repair in patients over 50 years old with symptomatic rotator cuff tears, using techniques like ultrasonography and MRI for evaluation.
  • - A total of 357 patients participated, showing significant improvements in pain and range of motion (ROM) for both treatments, but no notable differences between the two methods.
  • - In 1-year follow-up, 9.6% of patients who had surgery experienced a retear, while 6.7% of those receiving conservative treatment demonstrated tear progression, suggesting that conservative treatment can be equally effective as surgery for this patient group.
