The goal of this clinical trial is to test whether there is any effect on rotator cuff healing by making microfracture at the lateral side of the footprint. The main question it aims to answer are: * \[whether the lateralized microfracture could decrease the retear rate after arthroscopy rotator cuff repair.\] * \[whether the lateralized microfracture could improve the functional recovery after arthroscopy rotator cuff repair.\] Participants with medium to larger size rotator cuff tears will be randomly assigned to the study group treated with lateralized microfracture immediately after arthroscopy rotator cuff repair or the control group treated with conventional arthroscopy rotator cuff repair without microfracture.

RECRUITINGMagnetic Resonance Imaging (MRI)
The scans were evaluated for rotator cuff integrity and degree of re-tears (no re-tears, partial or complete re-tear) by an independent radiologist
Time frame: 24 months postoperative
Active range of motion of Shoulder
Active forward flexion, abduction and external rotation will be measured with a manual goniometer at the preoperative visit, 3 months and 24 months after surgery.
Time frame: Preoperative, 3 months and 24 months postoperative
Passive range of motion of Shoulder
Passive forward flexion, abduction and external rotation will be measured with a manual goniometer at the preoperative visit, 3 months and 24 months after surgery.

American Shoulder and Elbow Score
American Shoulder and Elbow scores (minimum 0 points, maximum 100 points, higher values are considered better outcomes) of patients with rotator cuff tears treated with and without lateralized microfracture at the preoperative visit, 3 months and 24 months after surgery.

University at California at Los Angeles Shouder Rating Scale
University at California at Los Angeles Shoulder Rating Scale(minimum 3 points, maximum 35 points, higher values are considered better outcomes) of patients with rotator cuff tears treated with and without lateralized microfracture at the preoperative visit, 3 months and 24 months after surgery.
Time frame: Preoperative, 3 months and 24 months postoperative
Visual Analog Scale for Pain
Visual Analog Scale for Pain(minimum 0 points, maximum 10 points, higher values are considered worse outcomes) of patients with rotator cuff tears treated with and without lateralized microfracture at the preoperative visit, 3 months, and 24 months after surgery.
