We aimed to introduce a new modified suture bridge technique and report the clinical outcomes and radiological assessments of modified suture bridge technique for medium rotator cuff tears.
Purpose: We aimed to introduce a new modified suture bridge technique and report the clinical outcomes and radiological assessments of modified suture bridge technique for medium rotator cuff tears. Methods: We prospectively followed 50 consecutive patients with medium rotator cuff tears treated with the modified suture bridge (MSB) or traditional suture bridge technique (TSB) from December 2018 and December 2019. On the basis of preoperative findings and MRI performance, 26 patients underwent MSB repair whereas 24 underwent TSB repair. Range of shoulder motion, visual analog scale score (VAS score), University of California-Los Angeles score (UCLA score), Constant-Murley shoulder score (Constant score), American Shoulder and Elbow Surgeons score (ASES score) were assessed. Magnetic resonance imaging were performed preoperatively and at 12 months postoperatively.

(A) Limbs of the sutures from the medial anchor were passed through torn tendon (B) the suture limbs were tied in a horizontal mattress suture pattern (C) the lateral row pressed the free tails of the knotted line on the greater tubercle of the humerus (D) the effect after completion of the TSB technique
(A) Limbs of the sutures from the medial anchor and 2 tendon sutures were passed through the same position of torn tendon (B) the lateral row pressed free tails of the two tendon lines on the greater tubercle of the humerus (C) after examination of sufficient tension and stable fixation, sutures of medial row was knotted (D) the effect after completion of the MSB technique

Cuff integrity grade of MRI assessment
Grade I: sufficient thickness of tendon; Grade II: sufficient thickness of tendon and partial high intensity within tendon; Grade III: insufficient thickness of tendon without discontinuity; Grade IV: slight discontinuity in 1 or 2 images of oblique coronal plane and sagittal plane; Grade V:obvious discontinuity of tendons in more than 2 images of both oblique coronal plane and sagittal plane.
Time frame: at 12 months postoperatively
Muscle atrophy grade of MRI assessment
Grade I: a ratio between 1.00 and 0.60 can be considered as normal or slightly atrophied; Grade II: values between 0.60 and 0.40 suggest moderate atrophy. Grade III: values below 0.40 indicate serious or severe atrophy.
Time frame: at 12 months postoperatively
Fatty degeneration grade of MRI assessment
Grade 0: completely normal muscle; Grade 1: muscle contains some fatty streaks; Grade 2: there is more muscle than fat; Grade 3: equal distribution of fat and muscle; grade 4: more fat was present than muscle. Among them, grade 0 is normal, grade 1 and 2 are considered moderate, grade 3 and 4 are classified as severe.
Time frame: at 12 months postoperatively
Range of shoulder motion
Different range of motion of shoulder joint
Time frame: at 12 months postoperatively
The Visual Analog Scale score
Assess pain on a scale of 0 (no pain) to 10 (worst possible pain).
Time frame: preoperatively

University of California-Los Angeles score
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
The score mainly consists of two parts. Patients subjectively evaluate pain and functional activity; and doctors objectively evaluate shoulder joint mobility and muscle strength. Possible scores range from 0 to 35, a higher score means a better result.

Constant-Murray Shoulder score
An assessment method often used by orthopedic surgeons when assessing the condition of patients with shoulder joints.Possible scores range from 0 to 100#a higher score means a better result.

American Shoulder and Elbow Surgeon score
The evaluation criteria used to assess shoulder joint function based on the patients' pain and accumulated daily activities. Possible scores range from 0 to 100. The higher the score, the better the shoulder joint function.
