AI Article Synopsis

  • The study investigates the high failure rate of rotator cuff repairs, especially in diabetic patients, and the unclear effects of Polydeoxyribonucleotide (PDRN) and polynucleotide (PN) on tendon healing.
  • In a diabetic rat model with chronic rotator cuff tears, administering PDRN and PN significantly improved tendon healing, increased load to failure, and reduced fatty infiltration.
  • The treatment also raised plasma levels of important growth factors, with PN demonstrating a longer-lasting effect compared to PDRN.

Article Abstract

Failure rate after chronic rotator cuff repair is considerably high. Moreover, diabetes mellitus is known as a compromising factor of rotator cuff tear. The effect of Polydeoxyribonucleotide (PDRN) and polynucleotide (PN) on tendon healing and fatty infiltration is unclear as tissue regeneration activator in diabetic state. Therefore, a diabetic rat model with chronic rotator cuff tear was made for mechanical, histologic and blood tests. In the animal study using a diabetic rat cuff repair model, the administration of PDRN and PN increased the load to failure of repaired cuffs and improved tendon healing and decreased fatty infiltration. Also, the plasma levels of vascular endothelial growth factor and fibroblast growth factor were elevated in PDRN and PN administrated groups. We concluded that PDRN and PN appear to boost tendon recovery and reduce the presence of fatty infiltration following cuff repair in diabetic state. Also, PN showed a later onset and a longer duration than PDRN associated with the mean plasma growth factors.

Muscle degeneration is a common issue caused by rotator cuff tear (RCT) which significantly affects prognosis. Muscle stem cells (MuSCs) play a crucial role to prevent muscle degeneration after RCT. However, the pathological changes and detailed molecular mechanism underlying the myogenesis of MuSCs after RCT remain incomplete.

Although mixing and matching components is a common, safe, and well-documented practice in hip revision surgery, our extensive search indicates that it has not been previously reported for shoulder arthroplasty. This case report presents the use of mixed implants in shoulder revision surgery to reduce morbidity and address flaws in the initial implant design. We describe a case of a patient with multiple epiphyseal dysplasia who was treated for osteoarthritis in his left shoulder with an anatomic shoulder replacement in 2014.

The rotator cuff, a vital group of tendons and muscles in the shoulder, is essential for stabilizing the joint and enabling a wide range of arm movements. Rotator cuff tears, common across all age groups, often cause significant pain and functional limitations. Rotator cuff repair surgery aims to alleviate pain, restore function, and improve quality of life.
