Poster 187: Similar Clinical and Patient Recorded Outcomes Amongst Older Patients over 65 Years of Age Compared to Younger Patients undergoing Arthroscopic Rotator Cuff Repair

OBJECTIVES: The purpose of our study was to determine if patients 65 years and over meet the minimally clinical important difference (MCID) for Patient-Reported Outcomes Measurement Information System Upper Extremity (PROMIS-UE), Depression (PROMIS-D), and Pain Interference (PROMIS-PI) at similar rates compared to a cohort of younger patients. METHODS: A retrospective review of a prospectively collected database of patients undergoing RCR was performed. Patients with completed preoperative and 6-month follow up postoperative PROMIS scores were included. A cohort of 65 years and older (65<) was compared to a cohort of 64 years and younger (64>=) in terms of their clinical outcomes and PROMIS scores. A propensity matched analysis was then performed, which matched patients 65+ years old 1:1 to a cohort of 50 years or younger via tear size and body mass index (BMI). RESULTS: A total of 318 patients were included with 79 patients ≥ 65 years (69.2 ± 3.4 years, mean ± SD) and 239 patients <65 years (55.1 ± 3.4 years). No significant differences were found in terms of gender, tear thickness, tear size, reoperation rate, retear rate, preoperative PROMIS-UE, PROMIS-PI, and PROMIS D scores, or change in postoperative PROMIS-UE, PROMIS-PI, and PROMIS D after 6 months. In the sub-analysis, 44 patients over 65 years of age were propensity matched to 44 under 50 years of age. No differences were found in PROMIS-UE change, PROMIS-D change, proportion meeting MCID PROMIS UE, and proportion meeting MCID of PROMIS PI after 6 months. Patients in the 65+ years group experienced larger changes in PROMIS PI scores (12.5 ± 9.6 vs 7.2 ± 7.5, p=0.005) while fewer patients experienced significant declines in PROMIS D scores (26% vs 47%, p=0.03). CONCLUSIONS: Patients ≥ 65 years experience no differences in reoperation or retear rate when compared to younger patients. Older patients undergoing RCR were more likely to have a larger improvement in pain scores but were less likely to have significant clinical change in their depression scores. With proper patient selection, patients ≥ 65 years can achieve clinically significant improvements 6 months after RCR that is similar to their younger counterparts.
