Rotator Cuff and Scapula Stabilizer Strengthening Protocol
The programme was based on the latest scientific literature23 (link)
28 (link)
29 (link) and clinical experience and focused on strengthening eccentric exercises for the rotator cuff and strengthening concentric/eccentric exercises for the scapula stabilisers. The programme consisted of six different exercises: two eccentric exercises for the rotator cuff (supraspinatus, infraspinatus, and teres minor), three concentric/eccentric exercises for the scapula stabilisers (middle and lower trapezius, rhomboideus, and serratus anterior), and a posterior shoulder stretch. Each strengthening exercise was repeated 15 times in three sets twice daily for eight weeks. The posterior shoulder stretch was performed for 30-60 seconds and repeated three times twice daily. From week eight to week 12, the exercises were repeated once a day. The exercises were individually adjusted and progressed with increased external load by using weights and elastic rubber band at the physiotherapist visits once every other week during the whole rehabilitation period. When necessary, the physiotherapist performed manual treatment by stretching the posterior glenohumeral capsule and pectoralis minor during the visits. The pain monitoring model30 (link) was used to find the individual resistance for each patient. The patients were not allowed to exceed 5 on this 0-10 scale when they performed the exercises; however, they were recommended to feel some pain during loading. After completion of an exercise session, increased pain had to revert to levels before exercise before the next session; otherwise, the external load was decreased. Great emphasis was placed on teaching good posture (thoracic spine extension and retracted shoulders) and to maintain this position during the exercises. After completion of the specific exercise programme (after 12 weeks), we recommended participants to maintain the daily home exercises for another two months. A more detailed description of the exercise programme can be found in the appendix on bmj.com.

Tendon Cells and Macrophage Co-culture Responses
Tendon-derived stromal cells from healthy hamstring and diseased supraspinatus were seeded at a density of 15,000 cells per well in a 24 well plate. Tendon cells were allowed to reach 70% confluence prior to stimulation with cytokines or addition of monocytes. Human monocytes (98% CD14+, 13% CD16+) were obtained from healthy donor buffy coats by 2-step gradient centrifugation as described in detail elsewhere (64 ). For co-culture experiments, 150,000 monocytes per well were added and allowed to differentiate into macrophages for 2 days prior to cytokine stimulation. Tendon-derived stromal cells in isolation and tendon-derived stromal cell-macrophage co-cultures were incubated in X-Vivo10 media (Lonza) containing 1% heat inactivated human serum (Sigma). Cells were treated as previously described (23 (link)) with either LPS (100ngmL-1, E. coli 055:B5. L2880, Sigma), IFNγ (20ngmL-1, R&D Systems), or IL13 (20ngmL-1, BioLegend), non-treated (vehicle only) cells served as controls for each experiment. After treatment, cells were then incubated at 37°C and 5% CO2 until harvest of the cell lysate for mRNA after 96 hours.

Rat Supraspinatus and Infraspinatus Tenectomy
This study was approved by the University of Michigan IACUC. 6-month old male Sprague Dawley rats (N=6) were used. Rats were anesthetized with 2% isoflurane, and the skin above the shoulder was shaved and scrubbed with povidone iodine. To create a full thickness supraspinatus and infraspinatus tear and prevent tendon reattachment, the right shoulders underwent a supraspinatus and infraspinatus tenectomy (19 (link)) after visualizing the tendons through a field established by a deltoid splitting incision and transacromial approach (20 (link)). The left shoulder underwent a sham surgical operation in which a transacromial approach was performed, but the tendons were left intact. The deltoid was closed using absorbable 3-0 chromic gut suture (J&J), and the skin and fascia closed using 5-0 nylon (J&J) and GLUture (Abbott). Subcutaneous buprenorphine (0.05 mg/kg) was administered for analgesia during postoperative recovery. Ad libitum weightbearing and cage activity were allowed, and rats were monitored for signs of distress or infection. 30 days after later, rats were anesthetized with pentobarbital (50 mg/kg), the supraspinatus and infraspinatus muscles were removed and their masses were recorded. The rats were euthanized by anesthetic overdose and induction of bilateral pneumothorax. Supraspinatus muscles were finely minced and prepared for RNA isolation. The distal halves of the infraspinatus muscles were used for histology, and the proximal halves were used for muscle fiber contractility.

Biomechanical Shoulder Testing Rig Protocol
The specimens were mounted to a validated shoulder testing rig as previously described, which allowed for positioning of the glenohumeral joint in 6 degrees of freedom (Fig. 1A) [18 (link)–22 (link)]. With the glenoid surface being in a horizontal position parallel to the floor, the scapula was fixed to a vertical linear bearing translator and lever arm system on top of an X-Y table, allowing for glenohumeral translation in the anteroposterior and superoinferior direction. The rotation of the humerus was defined as neutral with the bicipital groove being aligned with the anterior margin of the acromion according to Selecky et al. [17 , 23 (link)]. The rotator cuff muscles were loaded based on physiological cross-sectional area ratios with multiple lines of pull as previously described [24 (link), 25 (link)]. Specifically, two lines of pull were used for the supraspinatus, three for the subscapularis, two for the infraspinatus, and one for the teres minor (Fig. 1B) [18 (link), 25 (link)]. Each line of pull was loaded with 5 N, resulting in a total load of 40 N [18 (link), 25 (link)].

(A) Displaying a right shoulder specimen mounted to the shoulder testing rig. The scapula is fixed to a vertical linear bearing translator and lever arm system on top of an X-Y table, allowing for glenohumeral translation in the anteroposterior and superoinferior direction. During testing, an axial compression load of 40 N is constantly applied via the lever arm of the X-Y table to center the joint. As the humerus is fixed in the testing rig, the oppositely directed force of 30 N is consequently applied to the X-Y table (glenoid) in the posterior direction during external rotation (green arrow) and in the anterior direction (red arrow) during internal rotation. The force is applied via a friction-less cable, which is attached to a servohydraulic testing system or 30 N hanging weight, depending on the direction of force. (B) The rotator cuff muscles are loaded based on physiological cross-sectional area ratios with multiple lines of pull. Specifically, two lines of pull are used for the supraspinatus (orange), three for the subscapularis (blue), two for the infraspinatus (red), and one for the teres minor (yellow). Each line of pull is loaded with 5 N, resulting in a total load of 40 N

Arthroscopic Infraspinatus Muscle Release
The study protocol was approved by the local ethics committee. From 2008 to 2014, 10 volleyball players with substantial, clinically visible, atrophy of the ISP muscle of the dominant hand underwent arthroscopic SSN release. All 10 players were involved in volleyball at a competitive level, from the amateur division to the national team. The indication for surgery was poorly explained posterior shoulder pain with decreased range of ER and ISP muscle wasting. Surgery was performed only after failed rehabilitation for a minimum of 6 months focused on improvement in the kinetics of the scapula during arm movement as well as strengthening and electrostimulation of the ISP muscle. All patients underwent preoperative magnetic resonance imaging (MRI) in which substantial atrophy of the ISP muscle was confirmed (Figure 1) and those patients with substantial concomitant pathologies, such as rotator cuff tear, supraspinatus (SSP) muscle atrophy, or paralabral cyst, as a source of the symptoms were excluded.
Outcome measures included pre- and postoperative range of motion on the operated and contralateral side, pre- and postoperative strength in ER as per the modified Lovett scale (Table 1).28
Postoperative strength for the operated shoulder was measured with the Beslands SF-500 dynamometer; the selected unit was kilograms, which is more familiar to patients. The measurements were taken after a few minutes of warm-up, and the result was the arithmetic mean of 3 measurements. Strength was measured and compared with the contralateral side in 3 positions: ER with the arm at the side (ER1), ER with the elbow flexed to 90°, the arm abducted to 90° in the scapular plane, the forearm pronated (ER2), and Jobe test position.23
Objective shoulder functional was assessed with the Constant-Murley score (CMS).8 ,44
At the final follow-up, all athletes underwent radiological assessment with an ultrasound and a radiograph (anteroposterior and Y views). Last, muscle bulk was assessed visually and described as either having no improvement in atrophy, partial improvement, or complete recovery.

Arthroscopic Rotator Cuff Repair Technique
The diagnostic arthroscopy and tendon release were the same with the TOE-SB group. All repairs were made with double-loaded or triple-loaded suture anchors. Of which one was implanted at the bone-cartilage junction 8 mm posterior to the bicipital groove, and one was implanted at the lateral part of the greater tuberosity. Biceps tenotomy was done if more than 50% biceps tear was observed during the surgery, otherwise it was tenodesis with one suture limb of the medial row anchor. All sutures were managed by a Cuff Hook (Stryker, San Jose, CA, USA) suture manipulator. At the end of the intervention, all repairs were completely defined as repair up to the lateral end of the greater tuberosity footprint [13 (link)]. The complete surgical details are listed in Fig. 2.
