- Brief Summary
Shoulder pain is one of the most commonly reported musculoskeletal complaints, which negatively affects upper limb use, night rest, daily life activities, work, sports performance and autonomy. Rotator cuff disease represents the most common cause of shoulder pain and it is responsible for up to 70% of all shoulder related visits to clinicians. Its incidence furthermore is expected to grow as the population ages. A wide range of conditions are included under the umbrella term of rotator cuff disease, including rotator cuff tendinopathy, subacromial bursal pathology, and partial-thickness or full-thickness rotator cuff tears (RCTs). The latter ones, i.e. rotator cuff tears, form the indications for which the test devices, the SINEFIX implant and instruments, are intended.
Despite the high prevalence of this condition, the pathophysiology and healing potential are not well understood, making the condition challenging to predictably treat in some patient populations. RCTs may occur in young people as a consequence of trauma (e.g. acute shoulder dislocation), however RCTs typically present in middle-aged or elderly people and cannot always be attributed to precipitating events or trauma. Instead, they can be attributed to degenerative processes, and are therefore referred to as degenerative RCTs.
For RCTs, treatment options include both surgical and non-surgical (conservative) procedures.
In this context, the SINEFIX implant and instruments were developed to treat adult patients with rotator cuff lesions of size up to 2 cm through arthroscopic reconstruction.

Group Intervention Description SINEFIX Rotator cuff repair with the SINEFIX Rotator cuff repair with the SINEFIX implant, using the SINEFIX instruments
- Primary Outcome Measures
Name Time Method Healing integrity 3 months post operation Healing integrity will be assessed with the MRI by evaluating the visibility of the tendon underneath the implant (yes/no)
Bursitis 3 months post operation Presence of bursitis will be assessed with MRI (yes/no)
Re-tear rate 3 months post operation Re-tear rate will be assessed with MRI
Dislocation of the implant 3 months post operation Presence of dislocation of the implant will be assessed with MRI (yes/no)
- Secondary Outcome Measures
Name Time Method Shoulder function after rotator cuff repair (subjective evaluation) At 10 weeks, 6, 12, and 24 months Shoulder function after rotator cuff repair (subjective evaluation) will be assessed through the Subjective Shoulder Value (SSV) which ranges from 0% to 100% (best outcome)
Functional and clinical outcome after rotator cuff repair as compared with baseline At 6 months, 1 and 2 years follow-up Functional and clinical outcome after rotator cuff repair will be assessed using the change of the total Constant Murley score (range 0-100) as compared to baseline
Bursitis At 6, 12, and 24 months Presence of bursitis will be assessed with MRI (yes/no)
Safety endpoint During the intervention and the follow up time (up to 24 months) Safety of the device will be evaluated by systematically reporting device deficiencies (DDs), adverse events (AEs) and serious adverse events (SAEs) and by monitoring the frequency and incidence of these events
Surgery time Immediately post procedure The total procedure duration will be recorded as the surgery time
Usability and workflow assessment Immediately post procedure Usability and workflow assessment will be evaluated after each intervention through a practitioner's questionnaire covering different aspects of the implant and instruments
Functional and clinical outcome after rotator cuff repair At 6 months, 1 and 2 years follow-up Functional and clinical outcome after rotator cuff repair will be assessed using the total Constant Murley score, which ranges from 0 (worst outcome) to 100 (best outcome)
Shoulder function after rotator cuff repair (physical examination-active external rotation) At 10 weeks, 6, 12, and 24 months Shoulder function after rotator cuff repair (physical examination) will be assessed through a physical examination with assessment of range of motion for active external rotation (range 0°-90°)
Shoulder function after rotator cuff repair (physical examination-active anteversion) At 10 weeks, 6, 12, and 24 months Shoulder function after rotator cuff repair (physical examination) will be assessed through a physical examination with assessment of range of motion for active anteversion (0°-180°)
Healing integrity At 6, 12, and 24 months Healing integrity will be assessed with the MRI by evaluating the visibility of the tendon underneath the implant (yes/no)
Complications During the follow up time (up to 24 months) Complications will be systematically reported. Complications of particular interest for the purpose of the study are neurological problems, bleeding, impaired wound healing, infection and frozen shoulder.
Patient satisfaction At 10 weeks, 6, 12, 24 months The patient will be asked to rate his/her satisfaction with outcome of the surgical repair (0=completely unsatisfied, 1=unsatisfied, 2=satisfied, 3=completely satisfied)
Re-tear rate At 6, 12, and 24 months Re-tear rate will be assessed with MRI
Dislocation of the implant At 6, 12, and 24 months Presence of dislocation will be assessed with MRI (yes/no)
