WHAT HAPPENS TO PATIENTS IN THE LONG TERM WHEN WE DON'T REPAIR THEIR CUFF TEARS? TEN-YEAR ROTATOR CUFF QUALITY OF LIFE INDEX (RC-QOL) OUTCOMES FOLLOWING NONOPERATIVE TREATMENT OF PATIENTS WITH FULL-THICKNESS ROTATOR CUFF TEARS
Bibliographic record
Abstract
The purpose of this study was to examine long term, greater than ten year outcomes of patients with full thickness rotator cuff tears treated non-operatively. Patients with a chronic, full-thickness rotator cuff tear (demonstrated on imaging) who were referred by their physician for shoulder surgery were enrolled in this prospective study between October 2008 and September 2010. Patients then participated in a comprehensive non-operative treatment program. After the three month program patients were defined as “successful” or “failed”. “Successful” patients were essentially asymptomatic and did not require surgery. “Failed” patients were symptomatic and consented to surgical repair. All patients were followed up at one year, two years, and five years using a validated, disease specific quality of life score the RC-QOL, and whether or not they eventually underwent surgery during these time intervals. All of the patients who participated at the five year follow up were contacted for this study between 10 – 12 years (mean 11.4 years) post treatment. Original results from this study showed that 75% of patients were treated successfully with the non-operative program, while 25% failed and needed surgery. These numbers were maintained at two-year follow-up and five-year follow-up (previously reported). At greater than ten years, 88 patients were contacted for follow-up. Fifty-eight (66%) responded. The non-operative “success” group had a mean RC-QOL score of 80 (SD 18) at previously reported two-year follow-up and 82 (SD 16) at five-year follow-up. Forty one patients provided follow-up RC-QOL data at a mean of 11.4 years. Mean RC-QOL scores of the successfully treated non-operative group were actually higher than those who required surgery during the course of the study (success group mean 86, sd 12; surgery group mean 78, sd 24), although this was not statistically different (p = 0.27). Two patients had crossed-over from the successful group to undergo surgery between 5 – 11 years (one had an acute traumatic injury, and the other reported aggravation with activity). Non-operative treatment is an effective and lasting option for many patients with a chronic, full-thickness rotator cuff tear. While some may argue that non-operative treatment delays inevitable surgical repair, this long term study shows that patients can do very well over time.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
