An Evaluation of the Rotator Cuff Repair Research Pipeline.

ABSTRACT: Background:We conducted a study of recommendations from the American Academy of Orthopaedic Surgeons (AAOS) guideline, "Optimizing the Management of Rotator Cuff Problems." Using these recommendations, we conducted searches of clinical trial registries and bibliographic databases to note the extent to which new research has been undertaken to address areas of deficiency. Hypothesis:Newly conducted research regarding rotator cuff repair and injury is available that will fill knowledge gaps identified by the AAOS guideline. Study Design:Cross-sectional study. Methods:For each recommendation in the AAOS guideline, we created PICO (participants, intervention, comparator, outcome) questions and search strings. Searches were conducted of ClinicalTrials.gov, the World Health Organization's International Clinical Trials Registry Platform, MEDLINE via PubMed, and EMBASE to locate studies undertaken after the final literature search performed by the AAOS work group. Results:We located 210 newly registered trials and 448 published studies that are relevant to the recommendations made in the rotator cuff guideline. The majority of the recommendations have been addressed by relevant registered trials or published studies. Of the 448 published studies, 185 directly addressed the guideline recommendations. Additionally, 71% of the 185 published studies directly addressing the recommendations were randomized trials or systematic reviews/meta-analyses. The most important finding of our study was that the recommendations in the AAOS rotator cuff guideline have been adequately addressed. Conclusion:Orthopaedic researchers have adequately addressed knowledge gaps regarding rotator cuff repair treatment and management options. As such, the AAOS may consider a guideline update to ensure that recommendations reflect current findings in orthopaedic literature.

Project description:Purpose To compare patient-reported and surgical outcome measures in patients with and without secondary shoulder stiffness (SSS) undergoing rotator cuff repair (RCR). Methods Patients undergoing rotator cuff repair from 2014 to 2020 with complete patient-reported outcome measures (PROMs) by the short-form 12 survey (SF-12) were retrospectively reviewed to identify if operative intervention for SSS was performed alongside the RCR. Those patients with operative intervention for SSS were propensity matched to a group without prior intervention for stiffness by age, sex, laterality, body mass index, diabetes mellitus status, and the presence of a thyroid disorder. The groups were compared by rotator cuff tear (RCT) size, surgical outcomes, further surgical intervention, rotator cuff retear rate, postoperative range of motion (ROM), and SF-12 results at 1 year after surgery. Delta values were calculated for component scores of the SF-12 and ROM values by subtracting the preoperative result from the postoperative result. Results A total of 89 patients with SSS were compared to 156 patients in the control group at final analysis. The patients in the SSS group experienced a significant improvement in the delta mental health component score (MCS-12) of the SF-12 survey that was not seen in the control group (P = .005 to P = .539). Both groups experienced significant improvement by the delta physical health component score (PCS-12) of the SF-12 survey (SSS: 7.68; P < .001; control: 6.95; P < .001). The SSS group also experienced greater improvement of their forward flexion (25.8° vs 12.9°; P = .005) and external rotation (7.13° vs 1.65°; P = .031) ROM than the control group. Conclusions Operative intervention of SSS at the time of RCR has equivalent postoperative SF-12 survey outcome scores when compared to patients undergoing RCR without preoperative stiffness despite those patients having lower preoperative scores. Level of Evidence Level III retrospective comparative study.

Project description:Current evaluation of muscle fatty infiltration has been limited by subjective classifications. Quantitative fat evaluation through magnetic resonance imaging (MRI) may allow for an improved longitudinal evaluation of the effect of surgical repair on the progression of fatty infiltration.We hypothesized that (1) patients with isolated full-thickness supraspinatus tendon tears would have less progression in fatty infiltration compared with patients with full-thickness tears of multiple tendons and (2) patients with eventual failed repair would have higher baseline levels of fatty infiltration.Cohort study; Level of evidence, 2.Thirty-five patients with full-thickness rotator cuff tears were followed longitudinally. All patients received a shoulder MRI, including the iterative decomposition of echoes of asymmetric length (IDEAL) sequence for fat measurement, prior to surgical treatment and at 6 months after surgical repair. Fat fractions were recorded for all 4 rotator cuff muscles from measurements on 4 sagittal slices centered at the scapular-Y. Demographics and tear characteristics were recorded. Baseline and follow-up fat fractions were compared for patients with isolated supraspinatus tears versus multitendon tears and for patients with intact repairs versus failed repairs. Statistical significance was set at P < .05.The mean fat fractions were significantly higher at follow-up than at baseline for the supraspinatus (9.8% ± 7.0% vs 8.3% ± 5.7%; P = .025) and infraspinatus (7.4% ± 6.1% vs 5.7% ± 4.4%; P = .027) muscles. Patients with multitendon tears showed no significant change for any rotator cuff muscle after repair. Patients with isolated supraspinatus tears showed a significant progression in the supraspinatus fat fraction from baseline to follow-up (from 6.8% ± 4.9% to 8.6% ± 6.8%; P = .0083). Baseline supraspinatus fat fractions were significantly higher in patients with eventual failed repairs compared with those with intact repairs (11.7% ± 6.8% vs 7.1% ± 4.8%; P = .037).Contrary to our initial hypothesis, patients with isolated supraspinatus tears showed a significant progression of fatty infiltration. Patients with eventual repair failure had higher baseline fat fractions in the supraspinatus.
