Summary
Rotator cuff surgery outcomes depend on tear size and delay to treatment, not age or rehab. Electromyography findings correlate with successful rotator cuff reconstruction results.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomedical Engineering
Background:
- Full-thickness rotator cuff tears are common injuries.
- Surgical repair is a primary treatment option.
- Assessing long-term functional outcomes and influencing factors is crucial.
Purpose of the Study:
- To evaluate the functional outcomes of surgical treatment for full-thickness rotator cuff tears.
- To identify factors correlating with successful surgical outcomes.
- To assess shoulder strength and muscle electrical activity post-surgery.
Main Methods:
- Follow-up of 51 patients an average of 4 years after rotator cuff surgery.
- Assessment of shoulder function using the Constant score.
- Strength measurements and electromyographic evaluation of supraspinatus and infraspinatus muscles.
Main Results:
- 88.2% of patients achieved satisfactory functional scores.
- Treatment success correlated significantly with tear size and time from injury to surgery.
- Reduced shoulder strength and altered infraspinatus muscle activity were observed post-surgery.
- Electromyographic findings positively correlated with rotator cuff reconstruction outcomes.
Conclusions:
- Surgical outcomes for rotator cuff tears are influenced by tear size and treatment delay.
- Postoperative strength deficits and muscle activation changes are present.
- Electromyography can predict the success of rotator cuff repair.
