Early Versus Delayed Rehabilitation in Arthroscopic Rotator Cuff Surgery: A Dual Surgeon Comparative Cohort Study (SS-15)

Background: Current literature suggests a higher rate of rotator cuff disease development in patients with dyslipidemia (DL). Moderate to high levels of DL are associated with higher rates of retear and revision surgery after arthroscopic rotator cuff repair. Statins protect against development of rotator cuff disease and mitigate the need for rotator cuff repair. Purpose: We aimed to investigate the influence of DL and statin use on postoperative functional outcomes. Study Design: Cohort study; Level of evidence, 3. Methods: Between 2010 and 2016, 266 patients underwent arthroscopic double-row rotator cuff repair for atraumatic full-thickness tears. Evaluation was conducted preoperatively and at 3, 6, 12, and 24 months postoperatively. Three functional outcome measures were used (Constant Shoulder Score [CSS], Oxford Shoulder Score [OXF], and University of California, Los Angeles, Shoulder Rating Scale [UCLASS]), as well as a visual analog scale (VAS) for pain. DL and non-DL were classified through screening of health and assessment of lipid levels within 6 months of surgery (triglycerides, total cholesterol, low-density lipoprotein, and high-density lipoprotein). Patients with DL were divided into statin users and nonusers. Types and dosages of statins were recorded, and intensity and equivalency charts were employed for standardization. Mann-Whitney U test and Pearson chi-square test were used for analysis. Generalized estimating equations and linear mixed models were used to examine the influence of DL and statin dosage, respectively on percentage change of postoperative outcome scores. Results: Increased age was associated with a higher incidence of DL ( P < .001), and 86% of the DL group was taking statins. The DL group also exhibited poorer scores preoperatively (CSS, P = .001; OXF, P = .032). No significant difference in scores was elicited between the DL and non-DL groups at 24 months. However, patients with DL experienced greater percentage improvement of CSS and OXF from preoperative baseline than did patients without DL ( P = .008 and P = .034, respectively) at 24 months. There was no significant difference in 24-month functional outcomes between statin users and nonusers. No statistically significant change of CSS; OXF; UCLASS; or VAS was noted with increasing statin doses at 24 months. Conclusion: Patients with DL with perioperative statin usage did not have poorer 24-month functional outcomes after arthroscopic rotator cuff surgery compared with those in patients without DL.

Rotator Cuff Surgery

Introduction: Pain can be severe during the first days after arthroscopic surgery, and acute pain is an important outcome in clinical trials of surgical technique or anaesthetic strategy. A standardized, validated method of assessing acute postoperative pain would improve the quality of clinical studies, and facilitate systematic reviews and meta-analyses. A step on the way towards this standard is to investigate the methods most commonly used in recent literature. Methods: PubMed and CINAHL databases were searched, including studies of arthroscopic rotator cuff surgery with a primary pain-related outcome during the first postoperative week, published in English from 2012 to 2017. Results: A total of 47 studies were included, all measuring pain intensity using a pain rating scale. Most frequently used was the visual analogue scale using the anchors “no pain” and “worst pain imaginable”, with recordings at 1, 2, 4, 6, 8, 12, and 24 hours postoperatively. A total of 34 studies recorded analgesic consumption, usually as average cumulated consumption in mg. Time to first analgesic request or first pain were recorded in 11 studies, and 4 different starting points were used. Discussion: This review describes the currently most common methods of assessing acute postoperative pain in clinical trials of arthroscopic shoulder surgery involving rotator cuff repair, and the large variety of methods applied. Based on this study and international guidelines, several recommendations on how to measure and report postoperative pain outcomes in future trials are proposed.

Background: Arthroscopic repair of delaminated rotator cuff tears (RCTs) has shown poor prognoses. Despite the importance of delaminated tears, only a few studies have compared delaminated and nondelaminated tears. Purpose: This study aimed to compare the clinical outcomes and structural integrity after en masse arthroscopic rotator cuff repair between delaminated and nondelaminated RCTs and to evaluate whether infraspinatus tendon involvement affects the prognosis for delaminated tears after arthroscopic cuff repair, through use of propensity score matching for precise comparison. Study Design: Cohort study; Level of evidence, 3. Methods: This study included 180 consecutive patients with medium- or large-sized RCTs who had an arthroscopic rotator cuff repair with a minimum 2-year follow-up, of whom 57 and 123 had delaminated tears (group 1) and nondelaminated tears (group 2), respectively. The en masse repair technique using a single-row or transosseous-equivalent double-row suture-bridge technique was used for of all the delaminated cases. Preoperative and postoperative visual analog scale pain scores, shoulder active range of motion, American Shoulder and Elbow Surgeons (ASES) scores, and Constant scores were assessed. Magnetic resonance imaging was performed at least 24 months postoperatively to identify retear of the repaired rotator cuffs. After propensity score matching, 32 cases in both groups were successfully matched, and the clinical and radiological results were analyzed. Results: Before propensity score matching, postoperative clinical outcomes were improved, showing no significant differences between the groups, excluding forward elevation ( P = .011). Groups 1 and 2 had 17 (29.8%) and 11 retear cases (8.9%), respectively ( P < .001). After propensity score matching, only the ASES score (72.5 vs 77.1) showed a significant superiority in group 2 ( P = .038). Propensity-matched groups 1 and 2 had 8 (25.0%) and 2 (6.3%) retear cases, respectively ( P = .034). No significant difference was found in structural integrity depending on whether the RCT included the infraspinatus tendon (IST). The odds ratio for retear of the delaminated tears, including IST, was 5.5 (95% confidence interval, 1.0-30.0, P = .038). Conclusion: Delaminated RCT was a negative prognostic factor of structural integrity after repair and could affect the functional outcome. However, whether IST tear was involved had no effect on the prognosis after repair.
