“…[ 23 ] The Western Ontario Rotator Cuff (WORC) Index questionnaire is a self-report questionnaire consisting of 21 items representing 5 domains to assess disease-specific quality-of-life. [ 24 , 25 ] There are 6 questions in the physical symptoms domain, 4 in the sports and recreation domain, 4 in the work domain, 4 in the lifestyle domain, and 3 in the emotions domain. All DASH and WORC scores were converted into a standardized score out of 100.…”

ObjectiveThis pilot study aimed to inform future research evaluating the effectiveness of Platelet Rich Plasma (PRP) injection for tendinopathy.DesignRandomized control trial (RCT) and synchronous observational cohort studies. For the RCT, consecutive consenting patients treated at an academic sports medicine clinic were randomly assigned to either a PRP or placebo control group.SettingThe Glen Sather Sport Medicine Clinic, Edmonton, Canada.PatientsThe RCT included 9 participants with rotator cuff tendinopathy. The cohort study included 178 participants with a variety of tendinopathies.InterventionsPatients receiving PRP were injected with 4 ml of platelets into the supraspinatus and/or infraspinatus, while patients in the placebo group were injected with 4ml of saline. All participants undertook a 3-month standardized, home-based, daily exercise program.Main Outcome MeasuresParticipants in the RCT were re-evaluated 3, and 6 months post-injection. Change scores before and after injection on pain, disability and MRI-documented pathology outcomes were compared. In the cohort study, pain and disability were measured at 1, 2 and 3 months post-injection.ResultsFor the RCT, 7 participants received PRP and 2 received placebo injections. Patients receiving PRP reported clinically important improvements in pain (>1.5/10 on VAS), disability (>15 point DASH change), and tendon pathology while those receiving placebo injections did not. In the observational cohort, statistically and clinically significant improvements in pain and disability were observed.ConclusionThis pilot study provides information for planning future studies of PRP effectiveness. Preliminary results indicate intratendinous, ultrasound-guided PRP injection may lead to improvements in pain, function, and MRI-documented tendon pathology.Trial RegistrationControlled-Trials.com ISRCTN68341698

“…All DASH and WORC scores were converted into a standardized score out of 100. [ 26 , 27 ] Lower DASH scores indicate less disability while higher WORC scores indicate higher life quality. The minimum clinically important difference for the DASH and WORC were considered to be 15/100.…”

“…This increased stiffness in the rotator cuff could also increase overall shoulder stiffness and limit range of motion and overall joint function 6 . As the WORC scale mainly covers the physical symptoms of rotator cuff disease and its effect on various domains of life, 21 patients with lipid disorders are likely to have higher WORC scores because of increased physical limitation. The results of this study are also consistent with a recent study by Kim et al, 12 who used a numeric rating scale to measure pain over time in patients with supraspinatus tendinopathy after treatment.…”

The effect of lipid levels on patient-reported outcomes in patients with rotator cuff tears

BackgroundLipid disorders could be associated with the prevalence and outcomes of rotator cuff diseases. This study aimed to learn how levels of various types of lipids influence the patient-reported outcomes of patients with rotator cuff tears (RCTs).MethodsData from a cohort study of 135 patients with RCTs were used. The outcome measures included Western Ontario Rotator Cuff (WORC) index, American Shoulder and Elbow Surgeons (ASES) standardized shoulder assessment form, Single Assessment Numeric Evaluation, visual analog scale for pain and satisfaction, and Veterans RAND 12-Item Health Survey (VR-12). Multivariable random-effects models were built to examine how total cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein, and ratio of total cholesterol to HDL influence each outcome, controlling for covariates.ResultsAfter adjusting for age, gender, surgery, smoking, and baseline outcome values, patients with triglycerides >150 mg/dL had significantly higher pain visual analog scale (β = 5.86; P = .017) and lower VR-12 physical component summary (β = −2.71; P = .002) scores. Patients with low HDL had significantly worse WORC (β = 132.26; P = .020) and ASES (β = −7.05; P = .005) scores, more pain (β = 6.69; P = .024), and less satisfaction (β = −6.53; P = .008). The ratio of total cholesterol to HDL was associated with worse WORC (β = 58.46; P = .006) and ASES scores (β = −2.74; P = .002), more pain (β = 4.49; P < .001), and worse VR-12 physical component summary score (β = −1.03; P = .017).ConclusionsDyslipidemia may decrease the improvement of patient-reported outcomes in patients undergoing treatment for RCTs; high triglycerides and low HDL may have the most impact.

“…This index considers 5 variables in its assessment, including physical symptoms, physical activity, work, daily activity, and mentality and excitement. Each item is scored from 0 to 100, and the higher the score the worse the condition of the shoulder [11].…”

Corticosteroids or platelet-rich plasma injections for rotator cuff tendinopathy: a randomized clinical trial study

et al. 2021

Background Studies evaluating the role of both corticosteroids and platelet-rich plasma (PRP) in the treatment of rotator cuff (RC) tendinopathies have been contradicting. We compared structural and clinical changes in RC muscles after corticosteroids and PRP injections. Methods This is a randomized double-blind clinical trial. All individuals with diagnosis of RC tendinitis during 2014–2017 were considered. Individuals were randomly allocated to either receive PRP or corticosteroids. Overall, 3cc of PRP was injected within the subacromial joint and another 3cc was injected at the site of the tendon tear, under the guide of sonography. For the corticosteroid group, 1cc of Depo-medrol 40mg and 1cc of lidocaine (2%) was injected within the subacromial joint. Results Overall, 58 patients entered the study. Comparison of pain, range of motion (ROM), Western Ontario RC (WORC), Disability of Arm-Hand-Shoulder (DASH) scores, and supraspinatus thickness showed significant improvement during follow-ups in both groups (p<0.05). During 3 months of follow-up, pain improvement was significantly better within the PRP group during (from 6.66±2.26 to 3.08±2.14 and 5.53±1.80 to 3.88±1.99, respectively; p=0.023). Regarding ROM, the PRP group had significant improvement in adduction (20.50°±8.23° to 28°±3.61° and 23.21°±7.09° to 28.46°±4.18° for the PRP and corticosteroid groups, respectively; p=0.011) and external rotation (59.66°±23.81° to 76.66°±18.30° and 57.14°±24.69° to 65.57°±26.39°, for the PRP and corticosteroid groups, respectively; p=0.036) compared to the corticosteroid group. Conclusion We found that PRP renders similar results to that of corticosteroids in most clinical aspects among patients with RC tendinopathies; however, pain and ROM may show more significant improvement with the use of PRP. Considering that the use of corticosteroids may be contraindicated in some patients and may be associated with the risk of tendon rupture, we suggest the use of PRP in place of corticosteroid-based injections among patients with RC tendinopathy.
