Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
1. To determine the probability that an asymptomatic rotator cuff tear will become symptomatic over time.
2. To determine which epidemiological factors correlate with symptomatic progression.
3. To determine if symptomatic progression correlates with enlargement of the rotator cuff tear as determined at sonography.
4. To determine the value of routine sonographic scanning of the asymptomatic shoulder.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control - participants from cycles 1 & 2
no intervention. Control group is composed of participants from Cohort I (recruited during our first grant cycle) and from Cohort II (recruited during our second grant cycle). Continued observation is planned for those controls, partial tears and full tears who enrolled in study at age 65 years or younger and have less than 11 years of follow up.
No interventions assigned to this group
Cuff Tear Cohort III
These participants are being recruited from our clinical population and have been scheduled to undergo a standard of care rotator cuff repair and post op therapy. One shoulder has been indicated for rotator cuff repair and the contralateral shoulder is asymptomatic. Both shoulders will be monitored.
No interventions assigned to this group
Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Less than 11 annual visits of non-operative surveillance of study shoulder.
* Less than 3 annual visits following a rotator cuff repair of study shoulder.
* Age 65 years or younger.
* Surgical candidate for primary, double-row repair of a rotator.
* Able to comply with post operative therapy protocol.
* Bilateral partial or full thickness rotator cuff tears: one symptomatic requiring surgery and the contralateral shoulder asymptomatic.
Exclusion Criteria
* Use of crutch, cane or weight-bearing device on study shoulder.
* Moderate or severe glenohumeral arthritis.
* Inflammatory or other disease process affecting neurological/musculoskeletal systems that may impact weight-bearing activities or normal use of upper body.
* Inability to return for routine study visits.
* Traumatic injury to rotator cuff.
* Rotator Cuff Tear greater than 30mm in width.
* Advanced fatty muscle degeneration.
Patients who are currently enrolled but require a shoulder replacement will not remain in the study. Cohorts I \& II will now be considered the control group for comparison to those enrolled in this next recruitment period.
* Workman's Compensation claim involving the shoulders.
* Use of crutch, cane or weight-bearing device on study shoulder.
* Moderate or severe glenohumeral arthritis.
* Inflammatory or other disease process affecting neurological/musculoskeletal systems that may impact weight-bearing activities or normal use of upper body.
* Inability to return for routine study visits.
* Traumatic injury to rotator cuff.
* Rotator Cuff Tear greater than 30mm in width.
* Advanced fatty muscle degeneration.
