AI Article Synopsis

  • - The study focuses on comparing various surgical techniques for repairing Achilles tendon ruptures, emphasizing that surgery typically leads to better recovery outcomes, such as reduced re-rupture rates and faster rehabilitation.
  • - Thirty-two rabbits underwent Achilles tendon surgery using different suture methods, materials, and techniques, with their strength tested after recovery alongside sixteen normal rabbits.
  • - Results indicated that the parachute-like suture method provided the best tensile strength for the repaired tendon, making it the preferred choice for clinical use to enable early movement post-surgery.

Article Abstract

Background: Operative treatment has been advocated as the method of choice to repair Achilles tendon rupture as surgery results in reduced re-rupture rate and faster rehabilitation. Many surgical techniques have been introduced allowing for postoperative early motion of the ankle joint. However, it is currently very difficult for surgeons to determine the optimal treatment conditions for ruptured Achilles tendon with an increasing number of end-to-end suture methods, suture materials, and epitenon suture techniques.

Methods: In the present biomechanical experiment study based on an orthogonal design, thirty-two New Zealand white rabbits received Achilles tendon tenotomy and subsequent operative treatment to repair the tendon employing four end-to-end suture methods, four suture materials, and four epitenon suture techniques. The tensile strength of the repaired Achilles tendon was investigated at four rehabilitation periods, and in comparison with the results of another sixteen rabbits with normal Achilles tendons.

Findings: The end-to-end suture method contributed most to the final Achilles tendon tensile strength in addition to rehabilitation period, with the highest values occurring with the use of the parachute-like ("Pa" bone) suture method. The other two factors, namely, suture material and epitenon suture technique, had relatively little influence on the results.

Interpretation: The parachute-like ("Pa" bone) surgical technique is superior to the other three end-to-end suture methods, with enhanced tensile strength of the repaired tendon. This method allows for postoperative early kinesitherapy of the ankle and knee joints. Therefore, this technique is highly recommended in clinical situations for treatment of ruptured Achilles tendon.

Introduction: Tendon injuries represent an ongoing challenge in clinical practice due to poor regenerative capacity, structure, and biomechanical function recovery of ruptured tendons. This study is focused on the assessment of a novel strategy to repair ruptured Achilles tendons in a Nude rat model using stem cell-seeded biomaterial.

Methods: Specifically, we have used induced pluripotent stem cell (iPSC)-derived mesenchymal stem cells (iMSCs) overexpressing the early tendon marker Scleraxis (SCX, iMSC, iTenocytes) in combination with an elastic collagen scaffold.

Purpose: Acute midsubstance Achilles tendon ruptures are the most common tendon injuries in adults and the choice of surgical technique is still debated. The objective of this study is to evaluate the rate of iterative ruptures and postoperative complications at a minimum follow-up of one year of percutaneous sutures of the Achilles tendon, as well as to investigate the risk factors for rupture.

Methods: In this single-center retrospective study, 142 patients (119 men and 23 women, mean age of 46 years) were reviewed at a mean follow-up of 24 (12-38) months.

Introduction: The specificity of ultrasonography (US) for enthesitis in psoriatic arthritis (PsA) is unclear. The objective was to analyze the specificity of US enthesitis in Mode B and using Power Doppler (PD), for the diagnosis of PsA through a systematic review with meta-analysis.

Methods: Systematic review in PubMed 2010-June 2023, of studies of adult patients with confirmed PsA with or without a control group of non-PsA patients, reporting information on US enthesitis.
