Brief Summary: Rotator Cuff Syndrome is a commonly encountered musculoskeletal disorder in clinical practice, with an incidence ranging from 0.3% to 5.5%, and an annual prevalence of 0.5% to 7.4%. In addition, over time, with a monthly rate of 0.26%, this condition can progress to complete rotator cuff tendon injury resulting in worsening pain and shoulder function. The etiology of Rotator Cuff Syndrome is still controversial. What the investigators know is that in tendinopathies there are histological changes in the structure of the tendons, resulting in a change in the mechanical properties of the tendons and leading to a chronic often disabling pain condition. Although conservative therapy should still be considered the first choice in cuff tendinopathies, The clinical results of the various types of nonsurgical treatments are still mixed and often show poor efficacy. This explains the growing interest of the scientific community in developing new biological therapies that can both improve shoulder function and promote tendon healing. The aim of the study is to evaluate, through the Constant Murley Score (CMS), the performance of intra-articular treatment with a collagen-based medical device (MD-Shoulder Collagen Medical Device) in recovering joint function and reducing pain in Rotator Cuff Syndrome.

Detailed Description: This is a pilot monocentric Clinical Investigation based on a one sample design. The purpose of this research is to evaluate, through the CMS functional scale, the performance of intra-articular treatment with a collagen-based medical device in recovering joint function and reducing associated pain. The safety of the treatment will also be assessed. Variables will be assessed at 6 different times points: at baseline (day0), after weeks 2, weeks 4, months 3, months 6, and after months 12.

The total duration of the study will be 16 months. There will be a 4-month subject selection and recruitment period and a 12-month treatment and observation period.

A total of 24 subjects with painful shoulder in Rotator Cuff Syndrome will be enrolled. The recruitment phase will be closed no sooner than the number of subjects planned in the study has been reached. Enrollment will involve subjects with rotator cuff syndrome who are eligible according to the selection criteria. Diagnosis will be performed by the Principal Investigator through clinical examination and instrumental investigation with shoulder MRI. The investigators will explain the rationale for the investigation plan and the procedures involved to the eligible subjects. Consent to participate in the study will then be sought. Prior or ongoing the treatments of any kind will be documented.

In order to monitor analgesic consumption (Celecoxib 200mg / Paracetamol 1000 mg) used during the study in case of pain onset, a clinical diary will be given to the subject in which to indicate the day and dose of medication used.

Study & Design

Study Type: INTERVENTIONAL

Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Constant-Murley Score (CMS) at 3 Months	3 months after baseline (Day 0)	The primary outcome is the change from baseline in the Constant-Murley Score (CMS) at 3 months after the first intra-articular injection. The CMS is a validated clinical scale ranging from 0 to 100 points, where higher scores indicate better shoulder function and less pain. It includes four subdomains: pain (15 points), activities of daily living (20 points), range of motion (40 points), and strength (25 points). An increase of at least 13 points is considered very clinically significant. Results will be analyzed as the mean change in CMS from baseline (Day 0) to Month 3. Unit of Measure: Points on the Constant-Murley Scale (0-100)

Secondary Outcome Measures

Name	Time	Method
Evaluation of MD-Shoulder Collagen Medical With Cuff Integrity at Mouth 12 Compared to Day 0 by Performing With Magnetic Resonance Imaging (MRI) of the Treated Shoulder.	month 12	Secondary Endpoints will consist of the evaluation of MD-Shoulder Collagen Medical with cuff integrity at mouth 12 compared to day 0 by performing with Magnetic Resonance Imaging (MRI) of the treated shoulder.
