“…A relatively small tendon tear size within our study cohort is partially explained by our study protocol with selective inclusion of isolated supraspinatus tears. In line with other previous studies, preoperative MRI‐based parameters did not significantly predict postoperative shoulder function and tendon retear within our cohort . However, since it was not a main aspect of our study to evaluate the previously reported conventional MRI‐based predictors, we cannot rule out that we missed predictive effects due to our small cohort size and herefrom resulting low statistical power for the expected moderate‐to‐weak effects of these parameters.…”

Supraspinatus (SSP) tendon tears represent a common indication for shoulder surgery. Yet, prediction of postoperative function and tendon retear remains challenging and primarily relies on morphologic magnetic resonance imaging (MRI)-based parameters, supported by patients' demographic data like age, gender, and comorbidities. Considering continuously high retear rates, especially in patients with larger tears and negative prognostic factors, improved outcome prediction could be of high clinical value. Contrastenhanced ultrasound (CEUS) enables an assessment of dynamic perfusion of the SSP muscle. As a potential surrogate for muscle vitality, CEUS might reflect functional properties of the SSP and support improved outcome prediction after tendon repair. Fifty patients with isolated SSP tendon tears were prospectively enrolled. Preoperatively, SSP muscle perfusion was quantified by CEUS and conventional morphologic parameters like tear size, fatty infiltration, and tendon retraction were assessed by MRI. At six months follow-up, shoulder function, tendon integrity, and muscle perfusion were reassessed. The predictive value of preoperative CEUS for postoperative shoulder function and tendon integrity was evaluated. 35 patients entered the statistical analysis. Preoperative CEUS-based assessment of SSP perfusion significantly correlated with early postoperative shoulder function (Constant, r = 0.48, p < 0.018) and tendon retear (r = 0.67, p < 0.001). CEUS-based subgroup analysis identified patients with exceptionally high, respectively low risk for tendon retear. CEUSbased assessment of the SSP seemed to predict early shoulder function and tendon retear after SSP repair and allowed to identify patient subgroups with exceptionally high or low risk for tendon retear.

The purpose of this study was to investigate the clinical results of arthroscopic rotator cuff repair in patients with anterior greater tubercle cyst in magnetic resonance imaging (MRI). Methods: The cyst-present group comprised 38 patients with anterior greater tubercle cyst in MRI, and age-and sex-matched 30 patients without cyst in humeral head were included in the control group. The cystic group was divided into two groups, smaller than 5 mm (21 patients) and larger than 5 mm (17 patients), according to the cyst size. A total of three groups were created. In the evaluation of clinical outcomes, modified University of California at Los Angeles (UCLA) and the Western Ontario Rotator Cuff Index (WORC) were used. The visual analog scale (VAS) was used to assess pain. One-way analysis of variance was used to compare VAS, UCLA, and WORC scores among the groups. Results: There was a statistically significant difference in the clinical results of VAS, UCLA, and WORC among the cystic and noncystic groups in the anterior greater tubercle (p < 0.05). There was also a statistically significant difference in the clinical results of UCLA, WORC, and VAS scores according to the cyst sizes in the anterior greater tubercle cyst group (p < 0.05). Conclusion: Anterior greater tubercle cysts have negative effects on rotator cuff repair results. If the anterior greater tubercle cyst size is greater than 5 mm, the negative effects of rotator cuff repair results are more pronounced. An understanding of anterior greater tubercle cysts has a critical importance for rotator cuff surgery planning.

“…These findings have been supported by the imaging literature as well. Recently, in the setting of partial‐thickness and small full‐thickness tears, Chung et al described an association between the severity of tendinosis on MRI and repair failure that appeared more predictive than traditional measures of tear size and muscle atrophy, although their sample size was relatively small.…”

Recently, in the setting of partialthickness and small full-thickness tears, Chung et al 21 described an association between the severity of tendinosis on MRI and repair failure that appeared more predictive than traditional measures of tear size and muscle atrophy, although their sample size was relatively small. Nevertheless, although morphologic assessment clearly provides information on characteristics that indirectly reflect tendon quality (such as the degree of Hou et al-Elastography of the Rotator Cuff Tendon tendinosis), it does not directly capture the mechanical properties of the tendon and may fail to predict the tendon response to a tensile load.…”

Shear Wave Ultrasound Elastographic Evaluation of the Rotator Cuff Tendon

Shear wave elastography shows tendon softening in rotator cuff disease. It captures information not obtained by a morphologic evaluation alone; however, a poor correlation with symptoms suggests that SWE will be less useful in workups for shoulder pain than for preoperative assessments of tendon quality. Deltoid muscle softening seen in morphologically abnormal and symptomatic patients requires further exploration.
