Rotator cuff tears commonly cause shoulder pain and functional impairment, prompting surgical intervention such as miniopen and arthroscopic methods, each with distinct benefits. This study aimed to compare the clinical outcomes and complications of these two approaches. Methods: A retrospective analysis was conducted on 165 patients who underwent rotator cuff repair using either arthroscopic-assisted mini-open or full arthroscopic approaches. Patient demographics, tear characteristics, clinical outcomes, and complications were assessed, with statistical analyses conducted to discern differences between the groups. Results: Among the patients, 74 (53.2%) received the mini-open approach, while 65 (46.8%) underwent arthroscopic repair, with a mean follow-up of 19.91 months. The mini-open group exhibited significantly higher postoperative American Shoulder and Elbow Surgeons (ASES) scores compared to the arthroscopic group (P=0.002). Additionally, the mini-open group demonstrated a more significant improvement in ASES scores from preoperative to postoperative assessments (P=0.001). However, the arthroscopic method had a significantly longer operative time (P<0.001). Complications, including anchor placement issues, frozen shoulder, infection, and re-rupture, occurred in 17.3% of patients overall. Re-rupture rates were 13.5% for mini-open and 6.2% for full arthroscopic repair, with no significant difference between the two methods (P=0.317). Conclusions: Both the mini-open and arthroscopic methods yielded favorable clinical outcomes for rotator cuff tear treatment, but the mini-open group exhibited superior results. Surgeons should consider patient characteristics, tear attributes, and surgical expertise when selecting the appropriate technique. Level of evidence: III.

OBJECTIVE: To investigate whether granulocyte-colony stimulating factor (G-CSF) can decrease the extent of ovarian follicle loss caused by cisplatin treatment. METHODS: Twenty-one adult female Sprague-Dawley rats were used. Fourteen rats were administered 2 mg/kg/day cisplatin by intraperitoneal injection twice per week for five weeks (total of 20 mg/kg). Half of the rats (n=7) were treated with 1 mL/kg/day physiological saline, and the other half (n=7) were treated with 100 microg/kg/day G-CSF. The remaining rats (n=7, control group) received no therapy. The animals were then euthanized, and both ovaries were obtained from all animals, fixed in 10% formalin, and stored at 4degrees C for paraffin sectioning. Blood samples were collected by cardiac puncture and stored at -30degrees C for hormone assays. RESULTS: All follicle counts (primordial, primary, secondary, and tertiary) and serum anti-Mullerian hormone levels were significantly increased in the cisplatin+G-CSF group compared to the cisplatin+physiological saline group. CONCLUSION: G-CSF was beneficial in decreasing the severity of follicle loss in an experimental rat model of cisplatin chemotherapy.
