Loss to follow-up after surgery is problematic in that it is thought to lead to poorer outcomes. There is little research on the long-term outcomes of people who have been lost to follow-up vs. patients who attended all follow-up appointments. Rotator cuff repair is unique in that the postoperative course is lengthy, and the rehabilitation program is typically tightly supervised. Therefore, the aim of this investigation is to determine whether there is any long-term difference in functional outcomes after arthroscopic rotator cuff repair between patients who are noncompliant with follow-up appointments vs. those who are compliant with all follow-up. A database query was carried out which identified 782 patients who underwent arthroscopic rotator cuff repair at our institution during 2016. Patients were separated into 2 cohorts based on whether they were compliant with all follow-up appointments. Demographic variables such as age and sex were compiled along with objective details from surgery such as size of tear, number of anchors, and other pathologies treated. Patients who were lost to follow-up were contacted by phone to answer survey questions. A matching control group of patients who attended all follow-up appointments was identified based on demographics and surgery details using propensity score matching. The control group was then contacted by phone to answer survey questions. Statistical results were reported as P values. Minimum follow-up was set at 2 years. The nonsatisfactory follow-up cohort consisted of 44 people (average follow-up: 30 months), with the satisfactory follow-up cohort consisting of 57 people (average follow-up: 42 months). There was no statistical difference between groups in sex, age, American Shoulder and Elbow Surgeons scores, Single Assessment of Numeric Evaluation scores, number of anchors, number of tears, additional surgical procedures, and patient satisfaction with the surgery and the surgeon. Of the reasons patients gave for why they did not attend follow-up appointments, 25.0% felt fine or returned to work, 22.7% did not know why, 15.9% reported travel distance, 13.6% of patients gave other explanations, 11.4% reported unrelated medical issues, and 11.4% were unaware they missed any appointments. This study demonstrated that there is no difference in the outcomes of patients who attended all follow-up appointments vs. patients who prematurely discontinued follow-up after arthroscopic rotator cuff repair.
