Rotator Cuff Integrity and Clinical Outcomes 5 Years After Repair.

Not Applicable

Recruiting

Conditions: Rotator Cuff Tears
Rotator Cuff Tear or Rupture, Not Specified as Traumatic
Rotator Cuff Injuries

Interventions: Diagnostic Test: Ultrasonography imaging
Diagnostic Test: American Shoulder and Elbow Surgeons (ASES) Score
Diagnostic Test: The Constant-Murley score (CMS)
Diagnostic Test: The Disabilities of the Arm, Shoulder and Hand (DASH)

Brief Summary: The study gives an overview of surgically treated rotator cuff injury patients in Tartu University Hospital Sports Traumatology Centre during 2013-2019 and evaluates the integrity of rotator cuff at minimum 5 years after atraumatic rotator cuff tendon repair.

First stage of the study describes the study population, etiology of the injury (traumatic/atraumatic) and aims to answer the question whether the arthroscopic findings are in line with the preoperative imaging studies or not.

Second stage of the study focuses on atraumatic tendon tears assessing structural integrity of the tendons 5 years after repair using ultrasound imaging. The main question is - does the findings correlate with clinical outcomes and patient satisfaction.

Participants of the second phase of the study will be asked for an appointment to have their shoulders examined with ultrasonography and clinical outcomes are measured using the American Shoulder and Elbow Surgeons (ASES) Score, The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and The Constant-Murley score (CMS).

Detailed Description: High numbers of re-tear after rotator cuff surgery have been shown, though not always influencing patient satisfaction. If there is an atraumatic tendon tear, the risk of having a contralateral rotator cuff tendon tear is high.

The aim is to study surgically treated rotator cuff injury patients 5 years after repair to evaluate tendon integrity on ultrasonography and answer the question do the findings correlate with functionality and patient satisfaction. It has been shown that people over the age of 66 who have been diagnosed with rotator cuff tendon tear, have up to 50 % chance of having a rotator cuff tendon tear in contralateral shoulder (Yamaguchi, et al. 2006). Therefore the study will evaluate the function and the integrity of the rotator cuff in both shoulders.

Secondary Outcome Measures

Name	Time	Method
American Shoulder and Elbow Surgeons (ASES) score	5 years after primary repair	The higher the score, the better the outcome.
