Arthroscopic Implantation of a Bio-Inductive Collagen Scaffold for Treatment of an Articular-Sided Partial Rotator Cuff Tear

Background: The treatment of symptomatic partial rotator cuff tear has presented substantial challenge to orthopaedic surgeons as it can vary from conservative to surgical repair. Researches have established the influence of platelet rich plasma in healing damaged tissue. Currently very few data are available regarding the evidence of clinical and radiological outcome of partial rotator cuff tear treated with ultrasound guided platelet rich plasma injection in English literature. Materials and Methods: 20 patients with symptomatic partial rotator cuff tears were treated with ultrasound guided platelet rich plasma injection. Before and after the injection of platelet rich plasma scoring was done with visual analogue score, Constant shoulder score, and UCLA shoulder score at 8 weeks and third month. A review ultrasound was performed 8 weeks after platelet rich plasma injection to assess the rotator cuff status. Results: Our study showed statistically significant improvements in 17 patients in VAS pain score, constant shoulder score and UCLA shoulder score. No significant changes in ROM were noted when matched to the contra-lateral side (P < 0.001) at the 3 month follow-up. The study also showed good healing on radiological evaluation with ultrasonogram 8 weeks after platelet rich plasma injection. Conclusion: Ultrasound guided platelet rich plasma injection for partial rotator cuff tears is an effective procedure that leads to significant decrease in pain, improvement in shoulder functions, much cost-effective and less problematic compared to a surgical treatment.

Objective. To explore the value of real-time dynamic ultrasound and magnetic resonance imaging (MRI) in the diagnosis of rotator cuff injury. Methods. From January 2020 to June 2021, the clinical data of 55 patients with rotator cuff injury were collected. All patients were examined by real-time dynamic ultrasound and MRI at the same time within two weeks before surgery, which was confirmed by arthroscopy. The value of real-time dynamic ultrasound, MRI, and the real-time dynamic ultrasound combined with MRI in the diagnosis of rotator cuff injury was evaluated. Results. Among the 55 patients with rotator cuff injury, real-time dynamic ultrasound showed full-thickness rotator cuff tear in 12 patients (21.82%), including type I in 2 patients (3.64%), type II in 6 patients (10.91%), and type III in 4 patients (7.27%), and partial rotator cuff tear in 31 patients (56.36%), including type IV in 16 patients (29.00%), type V in 5 patients (9.09%), and type VI in 10 patients (18.18%). MRI showed full-thickness rotator cuff tear in 12 patients (21.82%), including type I in 2 patients (3.64%), type II in 6 patients (10.91%), and type III in 4 patients (7.27%), and partial rotator cuff tear in 37 patients (67.27%), including type IV in 20 patients (36.36%), type V in 7 patients (12.73%), and type VI in 10 patients (18.18%). The combined examination showed full-thickness rotator cuff tear in 12 patients (21.82%), including type I in 2 patients (3.64%), type II in 6 patients (10.91%), and type III in 4 patients (7.27%), and partial rotator cuff tear in 39 cases (70.91%), including type IV in 21 cases (38.12%), type V in 7 patients (12.73%), and type VI in 12 patients (21.82%). The diagnostic accuracy of real-time dynamic ultrasound in complete tearing, partial tearing and the overall accuracy were 92.31%, 73.81% and 78.18%, respectively. The diagnostic accuracy of complete tear, partial tear and the overall accuracy of MRI were 92.31%, 88.00% and 89.09%, respectively. The diagnostic accuracy of complete tear and partial tear and overall accuracy in the real-time dynamic ultrasound combined with MRI were 92.31%, 95.24%, and 94.55%, respectively. The diagnostic accuracy and overall diagnostic accuracy of the combined examination of partial tears were higher than those of the real-time dynamic ultrasound and MRI examinations alone. Conclusion. Real-time dynamic ultrasound and MRI have high application value in the diagnosis of rotator cuff injury, and the combined diagnosis is conducive to improving the diagnostic accuracy of patients with partial tear.

Partial Rotator Cuff Tear

Background: Atelocollagen has been studied for restoration of rotator cuff tendon. In this study, we attempted to evaluate the clinical outcome of ultrasound-guided atelocollagen injection in an outpatient clinic for patients with partial rotator cuff tear.Methods: We recruited 42 outpatients who visited our hospital from May 2019 to September 2019. Atelocollagen injection was performed in patients with partial rotator cuff tear diagnosed by magnetic resonance imaging and ultrasound. American Shoulder and Elbow Surgeons (ASES), Constant, Korean Shoulder Score (KSS) and Simple Shoulder Test (SST) scores, and range of motion were assessed before injection and after two months. Statistically, we analyzed the clinical results using the Wilcoxon signed rank test.Results: Finally, 15 patients were enrolled for analysis. There was no significant difference between pre- and post-injection in terms of range of motion, ASES (57.0 vs. 60.4), Constant (56.4 vs.58.9), KSS (64.6 vs.68.5), and pain-visual analog scale (4.2 vs.3.7), except function-visual analog scale (F-VAS; 6.3 vs.7.1) and SST (6.6 vs.6.9). A significant difference was found in SST (P=0.046) and F-VAS (P=0.009). According to the ultrasound results at 2 months, we found hyperechoic materials in three of seven patients. The most common complication of atelocollagen injection was post-injection pain (53%, 8/15).Conclusions: Ultrasound-guided atelocollagen injection for partial rotator cuff tear showed no significant change in terms of clinical outcomes, except for F-vas and SST score. Tendon regeneration was not clear due to the remnants of atelocollagen present at 2-month follow-up ultrasound. There seems to be alarming post-injection pain for 2 to 3 days in the patients who received atelocollagen injection in an outpatient clinic.
