Article Synopsis
- Surgery is a common treatment for Achilles tendon ruptures, but there's ongoing debate about the best surgical method.
- This study compared the biomechanical properties of two techniques—H-loop knotless double-row (HLDR) suture repair and Krackow suture repair—using cadaveric Achilles tendon specimens.
- Results showed that the HLDR technique was superior, demonstrating less elongation, smaller gap distances under load, more force needed to create gaps, and greater load to failure compared to the Krackow technique.
Article Synopsis
- The study aimed to establish thresholds for minimal clinically important difference (MCID) and patient-acceptable symptom state (PASS) for shoulder assessment scores (WOSI, Rowe, ASES, and VAS) after arthroscopic Bankart repair in patients with shoulder instability.
- Researchers reviewed data from 131 patients who had surgery, analyzing their preoperative and post-operative scores, using various statistical methods to set the MCID and PASS thresholds.
- Key findings included specific threshold values for MCID and PASS for each of the assessment scores, which can help predict patient outcomes based on preoperative assessments.
Objective: The sub-acromioclavicular (SAC) decompression is often performed during arthroscopic rotator cuff repair. However, the impact of SAC decompression on patients with postoperative shoulder stiffness (POSS) are controversial and unclear. This study is aim to evaluate the impact of additional sub-acromioclavicular (SAC) decompression during arthroscopic rotator cuff repair on the postoperative shoulder stiffness (POSS) in patients.

Objective: To investigate the synergistic interaction between the deltoid muscle and the rotator cuff muscle group in patients with rotator cuff tears (RCT), as well as the impact of the critical shoulder angle (CSA) on deltoid muscle strength.
Methods: A retrospective analysis was conducted on clinical data from 42 RCT patients who met the selection criteria and were treated between March 2022 and March 2023. There were 13 males and 29 females, with an age range of 42-77 years (mean, 60.
The most frequent operation for anterior shoulder instability is the arthroscopic Bankart repair, which has a positive outcome and a low rate of complications. A variety of restoration procedures have been reported to reconstruct labral height and reproduce a dynamic concavity-compression reaction. The longitude-latitude loop is a knotless high-strength suture method that simultaneously tightens the joint capsule in the warp and weft direction and resists tearing.

The purpose of this study was to evaluate the initial tendon-fixation strength of the Lark-Loop technique in arthroscopic suprapectoral biceps tenodesis and compare it with others commonly used techniques.
Methods: Thirty-three porcine superficial flexor digitorum tendons were harvested from a local slaughterhouse and randomly divided into three groups to perform three tendon fixation techniques (Lasso-Loop stich group, Lark-Loop stich group or Krackow stich group; 11 tendons each group) with a No.
Machine learning model successfully identifies important clinical features for predicting outpatients with rotator cuff tears.

Purpose: The aim of this study is to develop a machine learning model to identify important clinical features related to rotator cuff tears (RCTs) using explainable artificial intelligence (XAI) for efficiently predicting outpatients with RCTs.
Methods: A retrospective review of a local clinical registry dataset was performed to include patients with shoulder pain and dysfunction who underwent questionnaires and physical examinations between 2019 and 2022. RCTs were diagnosed by shoulder arthroscopy.
Objective: The absence of patellar ligament will bring about a severe negative impact on daily life. Many reconstruction techniques have been described in adults. However, there is a lack of technical introduction regarding the reconstruction of the patellar ligament in children.

However, so far, there is no gold standard treatment in all-inside arthroscopy. The purpose of the present study was to introduce and evaluate the functional outcomes of an innovative, all-inside arthroscopic high resistance loop (H-loop, high resistance to tissue cutout and 360° grasping of the tendon) technique for long head of biceps (LHB) tenodesis.

Method: From June 2020 to September 2020, a total of six patients (five women, one man) with arthroscopic rotator cuff repair using the H-loop knotless double-row technique were enrolled in our study. The average age is 54 years (range: 50-61 years).
