[Comparative study on effectiveness of injecting platelet-rich plasma with different concentrations of leukocytes under ultrasound in treatment of supraspinatus tendon injury].

Objective: To compare effectiveness of injecting platelet-rich plasma (PRP) with different concentrations of leukocytes under ultrasound in treatment of supraspinatus tendon injury.

Methods: A clinical data of 30 patients with supraspinatus tendon injury, who met the selection criteria and were admitted between December 2022 and December 2023, was retrospectively analyzed. Thirty patients were treated with 4 injections of leukocyte-poor PRP (LP-PRP, =10), leukocyte-rich PRP (LR-PRP, =11), and triamcinolone ( =9), with an interval of 7-10 days between each injection.

Long Head of Biceps Tendinopathy Is Associated With Age and Cuff Tendinopathy on MRI Obtained for Evaluation of Shoulder Pain.

Background: Shoulder pain-mostly related to rotator cuff tendinopathy-is the most common reason adults seek upper limb specialty care. Tendinopathy of the long head of the biceps may be part of rotator cuff tendinopathy, which most of us develop as we age. Evidence that these processes are related and that both are part of human shoulder senescence could contribute to a reconceptualization of shoulder tendinopathy as a single set of age-related changes, which are often well-accommodated, sometimes misinterpreted as an injury, and associated with notable nonspecific treatment effects, thus meriting caution regarding the potential for overtreatment.

Predicting bursal-side supraspinatus tendon tears with the acromioclavicular angle.

Background: Bursal-side supraspinatus tendon tears are a common form of rotator cuff injury, often associated with acromial impingement and other extrinsic factors. Existing anatomical parameters, such as the lateral acromion angle, acromial index, and critical shoulder angle, have been studied in relation to rotator cuff tears; however, reliable indicators specific to the risk of bursal-side supraspinatus tears remain lacking. The acromioclavicular (AC) angle, which reflects the angular relationship between the acromion and clavicle, may offer a new predictive marker for this specific pathology.

Efficacy of Diagnostic In-Office Shoulder Ultrasound in the Surgical Treatment of Full-Thickness Rotator Cuff Tears.

Background: Early surgical management of full-thickness traumatic rotator cuff tears (RCTs) may optimize functional outcomes, prioritizing timely diagnoses. Ultrasound and magnetic resonance imaging (MRI) are highly sensitive and specific modalities for RCT diagnosis, yet MRI remains the gold standard diagnostic tool despite increased costs and potential delays in care. Ultrasound can provide same-day diagnosis, thus possibly expediting care.

Platelet-Rich Plasma for Arthroscopic Rotator Cuff Repair: A 3-Arm Randomized Controlled Trial.

Background: Although there has been some amount of research into the use of platelet-rich plasma (PRP) after arthroscopic rotator cuff repair, most studies have not fully demonstrated its benefits. In addition, PRP formulations containing different concentrations of leukocytes have not been directly compared for rotator cuff repair.

Purpose/hypothesis: The purpose of this article was to determine whether arthroscopic rotator cuff repair combined with PRP injection, either leukocyte-rich PRP (LR-PRP) or leukocyte-poor PRP (LP-PRP), is superior to the control.

Volumetric Classification: Unveiling the True Extent of Rotator Cuff Tears.

Introduction: Rotator cuff injury diagnosis involves comprehensive clinical, physical, and imaging assessments, with MRI being pivotal for detecting and classifying these injuries. However, the absence of a universally accepted classification system necessitates a more precise approach, advocating for the use of three-dimensional (3D) modeling to better understand and categorize rotator cuff tears.

Methodology: This research was conducted as a prospective, single-institution study on 62 patients exhibiting full-thickness rotator cuff tears.

Arthroscopic Assessment of the Incidence of Biceps Pulley Lesions Associated With Rotator Cuff Tears: An Observational Study.

The shoulder joint houses a stabilizing structure called the biceps pulley. Biceps pulley lesions can trigger anterior shoulder pain and frequently coincide with rotator cuff tears, whose prevalence rises with age. In our study, we aim to assess the incidence of biceps pulley lesions associated with rotator cuff tears in patients undergoing arthroscopic repair, the possible associated factors, and whether MRI findings were correlated with them.
