Research and Clinical Validation of a Wearable Device-Based Remote Rehabilitation System for Postoperative Rotator Cuff Injury

This study included patients who underwent their first shoulder rotator cuff surgery at Peking University Third Hospital, diagnosed with small to medium rotator cuff tears based on MRI results. Participants were randomly divided into an online wearable device training group and an offline traditional rehabilitation group, with 36 individuals in each group. Before testing began, patients were ensured to participate voluntarily and had signed informed consent forms.

Atelocollagen ＆ Hyaluronic Acid Correlation With Enhancement of Rotator Cuff Healing: Synergistic Effect?

The purpose of this study is to analyze the correlation between the synergistic effects of atelocollagen and hyaluronic acid (HA) in enhancing rotator cuff healing postoperatively in patients undergoing rotator cuff repair surgery.The main questions it aims to answer are: * Does atelo Collagen aid in the rotator cuff repair healing process? * Does hyaluronic acid (HA) aid in the rotator cuff repair healing process? * Does the combined use of atelo collagen and HA in the rotator cuff repair healing process have a synergistic effect? The researchers will compare the use of atelo collagen and HA alone with no treatment to determine their effectiveness in rotator cuff healing. Participants will: * receive injections of atelo collagen or HA, either alone or in combination, during arthroscopic rotator cuff repair. * visit the clinic for medical checkups and tests every 3 months, 6 months, 1 year, and 2 years.

Shoulder Surgery Traditional vs Accelerated Rehabilitation Trial

This is a randomised controlled trial involving patients who have a double-row arthroscopic rotator cuff repair. Null hypothesis: There is no difference in outcome between standard rehabilitation and accelerated rehabilitation after arthroscopic rotator cuff repair. Following surgery, they will be randomised to one of two groups: 1. Standard rehabilitation, with enforced sling use for 6 weeks and a structured exercise programme. 2. Accelerated rehabilitation with no requirement to use a sling and a structured exercise programme. The primary outcome measure will be the Oxford Shoulder Score at 6 months. We will also collect data on postoperative pain, range of shoulder movement and other subjective outcome measures. All patients will have MRI scans at 6 months postoperatively to assess the integrity of the repair, allowing comparison of failure rates between groups.

Post-Market Clinical Follow-up (PMCF) Study of the Pitch-Patch for the Augmentation or Reinforcement of the Rotator Cuff

This is a clinical investigation study. It will verify the long-term safety and performance of the Pitch-Patch when implanted to reinforce partially repairable rotator cuff tears and used as described by the manufacturer's instructions. The medical device in this study is already on the market and is manufactured by Xiros Ltd. The Pitch-Patch is a single-use polyester prosthesis available in two sizes (30x20mm and 35x25mm). It is reinforced around the perimeter and around each eyelet to provide strength and stability to the device and repair. The study will collect data on patients who meet the entry criteria and have received the device. This is a single-armed study, meaning all patients will have a Pitch-Patch. The total length of the is expected to be 3 years. A minimum of 37 patients will be enrolled into the study. Patients will be enrolled at a study specific follow up visit 2-2.5 years after implant, and data for baseline and other time points prior to 2 years (3month, 6month, and 1 year post surgery) will be collected retrospectively from medical records if available.

A Randomized Controlled Trial on the Effectiveness of Early Versus Conservative Rehabilitation Following Rotator Cuff Repair

Background Rotator cuff tears (RCTs) are a common, costly, and often persistent musculoskeletal complaint, with an increasing number of shoulder pain patients undergoing surgical repair each year. Whereas many asymptomatic RCTs can be successfully managed non-surgically, when conservative treatment fails, surgery is recommended. However, there is a lack of consensus on the best approach to postoperative rehabilitation, an important factor in the recovery process of rotator cuff repairs. This study aims to investigate the effectiveness of early versus delayed rehabilitation following rotator cuff repairs. Objective This study aims to determine the effectiveness of early versus delayed rehabilitation following rotator cuff repairs. Method A two-armed, randomized controlled trial will be conducted in an outpatient physical rehabilitation department at a tertiary hospital. The sample will include 88 adults aged 18 years or older with RCTs. From the day after surgery, the intervention will engage in supervised passive range of motion (ROM) exercises, focusing on forward flexion and external rotation. They will receive daily exercise instructions, including table slides and active movements for the elbow, wrist, and hand, while also practicing passive shoulder flexion and abduction based on their pain limits. Participants are encouraged to do gentle pendulum exercises and passive movements three times daily to improve shoulder mobility. Active shoulder exercises will be restricted until six weeks post-surgery to ensure healing. Sling use will decrease by the sixth week, allowing for active ROM exercises to start. Participants in the control group will follow a delayed rehabilitation protocol, learning strict sling immobilization techniques for the first six weeks postoperatively. During this period, sling removal will be allowed only for basic exercises and daily activities, with no other shoulder movements encouraged initially. Sling use will end by the sixth week, followed by the start of active ROM exercises. Outcome measures will include shoulder ROM, muscle power, a numeric pain scale (NPS), shoulder pain disability index (SPADI), and EQ-5D-5L questionnaires assessed at 3, 6, and 12 months follow-up between the two groups. Rotator cuff integrity will be evaluated using MRI at baseline and at 12 months post-surgery. Conclusion We anticipate that this study will add to the body of knowledge required to make effective treatment choices on the management of patients following rotator cuff repairs. Ultimately, this trial aims not only to influence national rehabilitation guidelines but also to enrich the global evidence base concerning optimal rehabilitation strategies following rotator cuff repair, especially for populations in the Middle East and Gulf regions.

Decellularized Human Placental Extracellular Matrix Tissue for Rotator Cuff Repair Augmentation

The rotator cuff is a set of muscles and tendons that help move the shoulder. Tears in the rotator cuff are common, particularly as people age. Consequently, rotator cuff repair surgeries are common, as well. Despite the frequency with which rotator cuff repairs are performed, there remains a high rate of postoperative failure to heal. In such situations, there is a lack of connective tissue establishment between the rotator cuff tendon and the bone. One strategy to attempt to improve healing of the rotator cuff tendon back to the bone is via the use of extracellular matrix allograft. This treatment is composed of tissue from other humans, which is stripped of its cells so that just the scaffolding around the cells remains. This decellularized scaffolding can be placed at the rotator cuff healing site in an attempt to augment healing. Both animal studies and human studies have shown promise with this approach. Of those patients enrolling in the study, 50% will be assigned at random to receive a standard rotator cuff repair AND allograft treatment, while 50% will be assigned at random to receive standard rotator cuff repair WITHOUT allograft treatment. All patients enrolled in the study will also obtain an MRI at one year following surgery in order to assess tendon healing. Of note, one-year postoperative MRIs are not standard following rotator cuff repair - only those enrolled in the study will receive this MRI. There will be no financial consequence of receiving this MRI.

Phase 3 Study of the Efficacy and Safety of MR Arthrography Using the NEMO-103 Injection in Patients With Known or Suspected Shoulder Joint Diseases

The goal of this Phase 3 clinical trial is to evaluate whether MR arthrography enhanced with NEMO-103 injection (NEMO-103 Inj.) provides superior diagnostic imaging quality compared to unenhanced MRI in patients with known or suspected shoulder joint disorders, such as rotator cuff tendon tears, labral tears, and articular cartilage injuries. ⦁ The primary objective is to determine whether NEMO-103 Inj.-enhanced MR arthrography offers improved imaging quality in terms of joint distension, contrast resolution, and image sharpness compared to standard unenhanced MRI. Participation Details: * Each participant will undergo two MRI scans: one unenhanced and one enhanced with NEMO-103 Inj. * NEMO-103 Inj. will be administered once, during the second study visit. * Participants will attend a total of three site visits.

Telerehabilitation vs. In-person Physiotherapy in Young Elite Baseball Players

This study compares physical therapy delivered through video calls to in-person therapy for young baseball players with shoulder pain. The goal is to see if remote therapy is as effective and easier for them to stick with

FiberLocker® System Augmentation of Rotator Cuff Repairs

The purpose of this study is to prospectively evaluate healing, functional clinical outcomes, and safety of arthroscopic rotator cuff repairs augmented with the FiberLocker® System (encompassing the SpeedPatch® PET and the FiberLocker® Instrument SN). The primary outcome measure is healing evaluation based on Magnetic Resonance Imaging (MRI) at a minimum of 6 months post-operatively. The secondary outcome measures are the Sugaya classification, Goutallier Stage and tendon quality based on MRI as well as objective scores and patient-reported outcome measures (PROMs) from validated outcome scoring systems.

Stromal Vascular Fraction Cell Therapy to Improve the Repair of Rotator Cuff Tears

Rotator cuff disease is one of the most prevalent musculoskeletal conditions across the world. Patients with chronic rotator cuff tears often have substantial muscle atrophy and fatty infiltration. Surgical repair of the tear does not reverse the atrophy, and many patients continue to experience weakness, pain, and a persistent reduction in the quality of life. An important limitation in our ability to successfully rehabilitate these injuries postoperatively and return patients to normal function has to do with the poor quality of the muscle and tendon after rotator cuff repair. The stromal vascular fraction (SVF) of subcutaneous adipose tissue is highly enriched with cells (SVFCs) that can both directly participate in tissue regeneration by differentiating into myogenic and tenogenic cells, and indirectly by secreting growth factors and small molecules which activate pathways associated with healthy tissue regeneration. High numbers of autologous SVFCs can be isolated using the cost-effective, intraoperative Icellator (Tissue Genesis, Honolulu, HI) point-of-care system. This clinical trial will be determine if the use of SVFCs can enhance outcomes for patients who are undergoing surgical repair of a torn supraspinatus rotator cuff.

Rotator Cuff Failure With Continuity

This proposal's objective is to challenge and expand the current definition of rotator cuff healing by investigating tendon retraction - broadly defined as medial translation of the repaired tendon away from the bone with or without a defect - as a common and clinically predictive structural outcome following rotator cuff repair. The investigators' central hypothesis is that failure with continuity is a common yet unrecognized structural phenomenon of rotator cuff healing that is significantly and meaningfully correlated with clinical outcomes. The investigators' approach is to characterize tendon retraction using an array of implanted radio-opaque markers, and investigate its relationship to pre-operative tissue quality (MRI), post-operative repair structural integrity (MRI) and clinical outcomes in a 125-patient prospective cohort study. These patients will complete (1) validated questionnaires and range of motion testing pre-operatively, (2) CT imaging at day of surgery, 3 weeks, 3 and 6 months, and 1, 2 and 5 years post-operatively, (3) MRI at 3 weeks, 3 and 6 months, and 1, 2 and 5 years post-operatively and (4) questionnaires, range of motion and strength testing at 3 and 6 months and 1, 2 and 5 years post-operatively.

Autologous Adult Adipose-Derived Regenerative Cell Injection Into Chronic Partial-Thickness Rotator Cuff Tears

The purpose of this investigation is to evaluate the safety and superior effectiveness in functional improvement in patients with partial-thickness rotator cuff tears (PTRCTs) after the administration of a single injection of adipose-derived regenerative cells (ADRCs) into the partial-thickness rotator cuff tear compared to the administration of a single corticosteroid injection into the associated subacromial space.

Rotator Cuff Tendon Repair With FiberLocker System Patch Augmentation

The overall objective of this clinical investigation is to assess the safety and efficacy of full-thickness arthroscopic rotator cuff repairs augmented with the FiberLocker System for the subjects. The primary outcome of the investigation is to assess the safety after full-thickness arthroscopic rotator cuff repairs augmented with the FiberLocker System in terms of postoperative adverse events through the 12-month follow-up. Main secondary outcomes include measures of efficacy and clinical performance evaluated at 6-week, 4.5-month, and 12-month follow-ups including retear rate assessed using MRI and different functional performance scores.

ISB With SSNB & ANB

This study is a prospective, randomized, double-blind trial comparing patients who underwent arthroscopic rotator cuff repair and received an interscalene brachial plexus block (9 ml of 0.75% ropivacaine, 3 ml for each trunk) combined with suprascapular nerve block and axillary nerve block (each with 10 ml of 0.75% ropivacaine) versus those who received an interscalene brachial plexus block (9 ml of 0.75% ropivacaine, 3 ml for each trunk) combined with placebo suprascapular and axillary nerve blocks (each with 10 ml of 0.9% saline). The study will compare subjective pain scores (VAS score) and patient satisfaction preoperatively and at 1, 3, 6, 12, 18, 24, 36, and 48 hours postoperatively. Additionally, 5 ml of venous blood will be collected preoperatively and at 1, 6, 12, 24, and 48 hours postoperatively to analyze and compare serum levels of cortisol, IL-6, IL-8, IL-1β, substance P, serotonin, β-endorphin, and norepinephrine.

Effect of Vitamin D Supplementation on the Rehabilitation of Patients After Rotator Cuff Tear Repair

Rotator cuff tears are a significant health concern that severely affect shoulder joint mobility in patients. Common clinical manifestations of RCTs include shoulder pain, limited range of motion, joint instability, muscle weakness, and functional disability. In patients with rotator cuff tears, the prevalence of vitamin D deficiency ranges from 8.3% to 71%. Given its critical role in muscle strength and function, vitamin D is emerging as an important factor in the management of musculoskeletal disorders, including rotator cuff injuries. Despite the promising evidence regarding vitamin D's role in muscle strength and tendon healing, the specific impact of vitamin D supplementation on postoperative rehabilitation remains unclear. Given that vitamin D deficiency is easily diagnosed and treated, it is considered a modifiable risk factor that could be utilized in orthopedic care to improve patient outcomes. Vitamin D supplementation is a cost-effective and potentially efficient intervention that may enhance muscle strength, reduce postoperative pain, and improve joint function in patients recovering from rotator cuff repair. The objective of this study is to investigate the effects of vitamin D supplementation on postoperative outcomes in patients undergoing arthroscopic rotator cuff repair. The study will be conducted as a randomized controlled trial, with participants receiving either a daily dose of 4000 IU of vitamin D or a placebo. The primary outcomes to be evaluated include muscle strength, postoperative pain, and joint function. Blood samples will be collected at baseline, and after 3 months, 6 months, and 12 months of supplementation to monitor the effects of vitamin D on serum levels and its correlation with clinical outcomes.

Oxandrolone Rotator Cuff Trial

This study is about healing after a rotator cuff tear repair procedure. We hope to learn if a biologic medication: Oxandrolone, a synthetic derivative of the human hormone Testosterone (the principal male sex hormone and an anabolic steroid), given for 12 weeks following rotator cuff repair, is effective in aiding in the healing process and restoring muscle mass.

Blood Flow Restriction Exercise-induced Hypoalgesia

The goal of this crossover randomized clinical trial is to compare the acute effect on exercise-induced hypoalgesia (EIH) between isometric exercise with blood flow restriction (BFR) and isometric exercise alone in adults undergoing arthroscopic rotator cuff repair. It is presumed that the addition of BFR to isometric exercises induces a greater effect in EIH. Patients who agree to participate in this research will be randomly assigned to two intervention sequences (AB or BA), where intervention A (experimental) corresponds to isometric exercises with BFR, and intervention B (control) corresponds to isometric exercises alone. For one week, each participant attended two sessions, separated by a 72-hours wash-out period. The primary variables will be the pressure pain threshold (PPT) and conditioned pain modulation (CPM). Secondary variables will be the pain intensity and distribution, kinesiophobia, upper extremity disability, and quality of life. Results will be measured before intervention (T1, pre-intervention), immediate after intervention (T2, post-intervention 1) and 10 minutes after intervention (T3, post-intervention 2).

Exploring the Feasibility of Silk Fibroin Surgical Mesh in Rotator Cuff Tears Repair Enhancement

Rotator cuff tears result in shoulder joint pain and movement disorders, affecting patients' daily lives. The incidence rate rises with age and can be as high as 54% among people over 60 years old. Most rotator cuff tears are unable to heal spontaneously, and the tear area may gradually expand over time. Currently, the main surgical treatment for rotator cuff tears is to use suture anchors to stitch the rotator cuff tendon tissue back to the original anatomical insertion point. Large rotator cuff tears are often accompanied by fat infiltration and tendon retraction. When forcefully sutured, the tension is relatively high, which may lead to non-healing and re-tearing of the rotator cuff. Research indicates that the re-tear rate after rotator cuff tear repair is 20% - 30%, and this probability can reach 40% - 50% for large rotator cuff tears. For these irreparable and large tears, rotator cuff repair typically requires patch augmentation techniques. Surgeries are based on restoring the force couple effect of the rotator cuff as much as possible and covering it with repair materials to achieve reinforcement. Silk fibroin surgical mesh is made of silk fibroin which has good biocompatibility and can be generally placed in the area of rotator cuff tears that cannot be repaired through conventional surgeries. By providing support to the injured rotator cuff tissue, it improves the repair effect. It can reestablish the integrity of the rotator cuff, reducing mechanical tension at the repair site and maintaining the stability of the glenohumeral joint. Besides, it can also promote tissue healing, and cell infiltration and growth, thereby facilitating the biological repair of the injured rotator cuff and reducing the occurrence of postoperative re-tears.

Application of Shock Wave Technique in Conservative Treatment of Rotator Cuff Tear

This study is a prospective cohort study and is a single-center clinical trial. Sample: This study will enroll about 22 patients from the Department of Sports Medicine and rehabilitation outpatient department of Beijing Third Hospital who are diagnosed with rotator cuff tear and choose conservative treatment.

Perioperative Polmacoxib Reduce Opioid Consumption for Post Operative Pain After Rotator Cuff Tear.

1. \*\*One day (±1 day) before surgery:\*\* The investigator or designated study staff will thoroughly explain the clinical trial process to the participant and their guardian (representative) based on the informed consent form and provide the form so that all participants and their guardians have sufficient time to read, discuss, and decide. Participants who agree to participate in the clinical trial will voluntarily sign the written consent form and receive a copy of the signed consent form before any study-related procedures are conducted. The clinical trial site will assign a screening number to patients who voluntarily provide consent and undergo screening. The screening number can be assigned in the order in which the participants sign the consent within the study site. After confirming eligibility based on inclusion/exclusion criteria, randomization will be performed to assign participants to either the treatment group or the control group (with a 1:1 ratio). If assigned to the treatment group, participants will receive \'Polacoxib (preventive Acelex cap 2mg) once daily, NSAIDs-excluded non-opioid/opioid analgesics - PRN use.\' If assigned to the control group, participants will receive NSAIDs-excluded non-opioid or opioid analgesics. Data will be collected by comparing the two groups in a double-arm setup. Pain scores, UCLA/ASES scores, and joint range of motion will be collected, and this data will be valid up to 3 months before the surgery. (For patients taking NSAIDs or Ultracet, the dose will be maintained until v5.) 2. \*\*Two hours before surgery:\*\* Administration of medication begins. 3. \*\*Three days after surgery:\*\* Collect pain scores and the cumulative number of NSAIDs-excluded non-opioid or opioid analgesic doses (post-surgery). Non-opioid or opioid analgesics (e.g., Fentanyl injection or Ultracet) will be used to manage post-surgical pain, and the number of doses will be collected to assess the participant's pain. 4. \*\*Two weeks after surgery:\*\* An outpatient visit will be conducted one week after discharge. Collect pain scores and the cumulative number of NSAIDs-excluded non-opioid or opioid analgesic doses at the two-week mark. 5. \*\*Six weeks after surgery:\*\* Collect pain scores and the cumulative number of NSAIDs-excluded non-opioid or opioid analgesic doses. 6. \*\*Three months after surgery:\*\* MRI will be performed to check for re-tears (optional for participants). This visit will be the study's completion visit, during which pain scores, UCLA/ASES scores, joint range of motion, and cumulative doses of NSAIDs-excluded non-opioid or opioid analgesics will be collected. If adverse events occurring during the treatment period have resolved before this completion visit, no additional safety follow-up will be performed, and this visit will be considered the end of the clinical trial. If adverse events have not resolved by the completion visit, follow-up will continue until the adverse events have either returned to pre-study or baseline levels, or the principal investigator or designee determines that the adverse events have stabilized, or no further follow-up is deemed necessary. This follow-up will mark the completion of the clinical trial.

Superior Capsular Reconstruction vs. Partial Repair for Massive Rotator Cuff Tears

Little evidence exists to guide treatment in patients with massive irreparable rotator cuff tears (MRCTS). Arthroscopic partial rotator cuff repair (PRCR) has the longest record of use. The new technique of superior capsular reconstruction (SCR) has more recently been described. Despite high enthusiasm for this technique, its effectiveness, cost and safety profile have not been established. The long-term goal of this study is to perform a multicenter randomized control trial to evaluate the effectiveness of SCR compared to PRCR in patients with MRCTS. The current study is a pilot required to support the development of an expanded formal clinical trial.

Operative Versus Non-operative Management of Rotator Cuff Tear

This study aims at determining the effectiveness and cost-effectiveness of surgical management of full-thickness rotator cuff tears compared to conservative treatment. The research setting is prospective, randomised, and controlled. The aim of the study is to search out evidence based data of indications for rotator cuff repair. The investigators also aim at offering patients the most efficient and effective treatment and reduce the number of operations that do not have sufficient effectiveness. The data obtained will facilitate developing guidelines for referrals to a specialist when rotator cuff tear is suspected. The investigators hypothesize that there are subgroups of patients suffering from rotator cuff tears that benefit from surgery whereas other subgroups are best treated conservatively.

Study on the Application of Shock Wave Technique After Rotator Cuff Operation

This study is a prospective cohort study and is a single-center clinical trial. The subjects of this study were patients who underwent rotator cuff repair in the Department of Sports Medicine and the Department of Rehabilitation in the Third Hospital of Beijing Medical University. The sample size of this study is about 2600 cases. We will collect the results of shoulder joint function score, quality of life score, pain score and MRI examination of all participants at baseline. Meanwhile, epidemiological data and related clinical characteristics of patients will be collected at the time of enrollment. All the collected data information was entered into the computer for statistical analysis, and the prognosis of patients under different programs was evaluated.

Surgical Management of Irreparable RC Tears

The primary goal will be to compare the early postoperative recovery outcomes and complications from a series of surgical treatments for massive or irreparable rotator cuff tears. The secondary goal will be to assess factors that impact the outcomes of these reconstructions for irreparable posterosuperior rotator cuff tears.
