Prognostic Factors for Clinical Outcomes After Arthroscopic Rotator Cuff Repair

Abstract

Background: Limited knowledge exists regarding prognostic factors after rotator cuff repair. Purpose: To identify pre- and perioperative predictors for functional outcomes after arthroscopic rotator cuff repair. Study Design: Case-control study; Level of evidence, 3. Methods: This study included patients who underwent arthroscopic rotator cuff repair between January 2013 and April 2019 and who had preoperative magnetic resonance imaging scans. The procedures were performed by 4 shoulder surgeons at a single institution. Excluded were patients who had previous surgeries, those who underwent open surgery, and those without 12- and 24-month follow-up clinical data. Patient-reported outcomes (American Shoulder and Elbow Surgeons [ASES] Standardized Shoulder Assessment Form and University of California, Los Angeles [UCLA] Shoulder Rating Scale scores) were assessed preoperatively and at 6, 12, and 24 months postoperatively. Using multiple linear regression analysis, the authors evaluated the influence of 29 variables relating to patient, lesion, and procedure characteristics on postoperative outcomes, with the 24-month ASES score as the dependent variable. Results: The study sample consisted of 474 patients (500 shoulders). The median ASES score increased from 41.6 preoperatively to 88.3 at 24 months ( P < .001), and the median UCLA score increased from 14 preoperatively to 32 in the same period ( P < .001). The following variables were found to be independent predictors for higher 24-month postoperative ASES score: male sex, absence of rheumatologic disease, older age, lower degree of supraspinatus muscle fatty degeneration, acromioplasty, and a higher preoperative ASES score. Conclusion: The prognostic factors for better clinical results at 24 months after arthroscopic rotator cuff repair were male sex, absence of rheumatologic disease, older age, lower degree of fatty degeneration of the supraspinatus muscle, concomitant acromioplasty, and higher preoperative ASES score.

Factors affecting medium-term patient satisfaction after arthroscopic repair of small to medium-sized rotator cuff tears: An observational study

“…Nicholson et al [ 20 ] reported that smoking was the only factor significantly adversely influencing patient-reported outcomes. Malavolta et al [ 21 ] did not find that smoking affected clinical results. This was probably due to the inclusion criteria used in their study for determining a patient as a smoker which grouped former smokers and active smokers together as opposed to only active smokers in the present study.…”

The Effect of Acromioplasty Performed During Rotator Cuff Repairs on Clinical Outcomes in Patients With Type 3 Acromion: A Retrospective Study

“…RC syndrome is one of the common problems in orthopaedics and traumatology, with a growing global incidence [4,10]. Factors such as age, comorbid diseases, activity levels, and smoking are among the known risk factors for RC tears [4].…”

Longitudinal Analysis of the ASES and Constant–Murley Scores, and the Internal Rotation/Shift and Jobe Tests Following Arthroscopic Repair of Supraspinatus Lesions

“…Although various tests are used to determine the progression of patients following a rotator cuff repair, the American Shoulder and Elbow Surgeons Shoulder (ASES) [ 13 , 14 , 15 ] and Constant–Murley shoulder (CMS) [ 16 ] scores are common patient self-evaluations used to determine functional ability. Malavolta et al [ 17 ] previously reported that the ASES is a good prognostic tool for use at the 6-, 12-, and 24-month postoperative periods after supraspinatus repair. Similarly, the CMS has been reported to correlate with the isokinetic evaluation of the external rotation strength at the 6- and 12-month post-operative periods for rotator cuff repair [ 18 ].…”
