Rotator Cuff Tear

Basic Overview

The rotator cuff is a tendinous structure composed of 4 muscles (supraspinatus, infraspinatus, teres minor, subscapularis) that surround the glenohumeral joint, providing shoulder stability and enabling overhead movement and rotation. A rotator cuff tear refers to a partial or full-thickness rupture of one or more of these tendons.

Etiology: The primary causes are age-related degenerative changes (reduced tendon vascularity in patients over 40), acute trauma (e.g., fall on an outstretched hand, heavy lifting), and chronic repetitive overhead motion (e.g., badminton, tennis, swimming, occupational overhead work).
Clinical Manifestations: Core symptoms include persistent shoulder pain (worse at night and with overhead movement), weakness in shoulder abduction and external rotation, limited glenohumeral mobility, and muscle atrophy of the supraspinatus/infraspinatus in chronic massive tears.
Diagnosis: Physical examination (Neer test, Hawkins-Kennedy test, Jobe empty can test) is used for initial screening, with MRI or magnetic resonance arthrography (MRA) as the gold standard for assessing tear size, location, and retraction. X-rays rule out glenohumeral osteoarthritis, acromial spurs, or fractures, and ultrasound allows dynamic evaluation of tendon function.

Standard Treatment Modalities

Treatment is stratified based on tear size, symptom severity, patient age, and functional demand:

Conservative Management: First-line treatment for small, partial-thickness tears, asymptomatic tears, or low-demand elderly patients. Interventions include activity modification, physical therapy to strengthen rotator cuff and periscapular muscles, NSAIDs for pain control, corticosteroid or hyaluronic acid intra-articular injections, and cryotherapy.
Surgical Treatment: Indicated for full-thickness tears with persistent symptoms despite conservative treatment, massive tears, acute traumatic tears in young active patients, or tears with progressive weakness and functional loss. The gold standard is arthroscopic rotator cuff repair, with techniques including single-row, double-row, and suture-bridge fixation. For massive, irreparable tears, patch augmentation, tendon transfer, or reverse total shoulder arthroplasty (rTSA) may be performed. Structured postoperative rehabilitation is essential for tendon healing and functional recovery.

Core Advantages of Treatment in China

World-Leading Arthroscopic Minimally Invasive Expertise

: Top orthopedic centers in China have achieved surgical success rates for arthroscopic rotator cuff repair equivalent to leading Western institutions, with extensive experience in complex cases including massive tears, revision surgery, and tears combined with glenohumeral instability. Innovative techniques such as suture-bridge fixation and biological patch augmentation are widely standardized, with minimal surgical trauma and rapid postoperative recovery.

Unique Integrated TCM Conservative Treatment System

: A core advantage of Chinese care is the mature TCM conservative protocol for early and partial rotator cuff tears, including acupuncture, tuina massage, oral and topical herbal medicine, and small needle knife release. Combined with modern rehabilitation training, this integrated approach effectively relieves pain, improves shoulder function, and avoids surgery for over 60% of early-stage patients, a therapeutic option not widely available in Western countries.

Unrivaled Case Volume and Complex Case Management

: With the largest population of rotator cuff tear patients globally, Chinese shoulder surgeons have accumulated unparalleled experience in managing rare and complex cases, including irreparable massive tears, chronic tears with muscle atrophy, and post-traumatic rotator cuff injuries.

Rapid Translation of Innovative Technologies

: China is at the forefront of translating cutting-edge technologies into clinical practice for rotator cuff injuries, including 3D-printed personalized patches, stem cell therapy to promote tendon healing, and robot-assisted precise suture placement. These innovations have significantly improved tendon healing rates and reduced re-tear rates.

Full-Cycle Rehabilitation Management

: China has established a standardized full-cycle management system from preoperative assessment and surgical planning to staged postoperative rehabilitation. The integration of TCM rehabilitation modalities significantly improves postoperative functional recovery rates and reduces the incidence of re-tear compared to standard Western rehabilitation protocols.
