Exploring Metabolic Mechanisms in Calcific Tendinopathy and Shoulder Arthrofibrosis: Insights and Therapeutic Implications

Rotator cuff calcific tendinopathy and arthrofibrosis of the shoulder (adhesive capsulitis) are debilitating musculoskeletal disorders that significantly impact joint function and impair quality of life. Despite its high prevalence and common clinical presentation, the metabolic mechanisms underlying these conditions characterized by pain, and reduced mobility, remain poorly understood. This review aims to elucidate the role of metabolic processes implicated in the pathogenesis of calcific tendinopathy and shoulder arthrofibrosis. We will be focusing on the mechanistic role of how these processes contribute to disease progression and can direct potential therapeutic targets. Calcific tendinopathy is marked by aberrant calcium deposition within tendons, influenced by disrupted calcium and phosphate homeostasis, and altered cellular responses. Key molecular pathways, including bone morphogenetic proteins (BMPs), Wnt signaling, and transforming growth factor-beta (TGF-β), play crucial roles in the pathophysiology of calcification, calcium imbalance, and muscle fibrosis. In contrast, shoulder arthrofibrosis involves excessive collagen deposition and fibrosis within the shoulder joint capsule, driven by metabolic dysregulation and inflammation. The TGF-β signaling pathway and inflammatory cytokines, such as interleukin-6 (IL-6), are central to the fibrotic response. A comparative analysis reveals both shared and distinct metabolic pathways between these conditions, highlighting the interplay between inflammation, cellular metabolism, extracellular matrix remodeling, calcific deposition, and calcium migration to the glenohumeral joints, resulting in adhesive capsulitis, thereby providing insights into their pathophysiology. This review discusses current therapeutic approaches and their limitations, advocating for the development of targeted therapies that address specific metabolic dysregulations. Future therapeutic strategies focus on developing targeted interventions that address the underlying metabolic dysregulation, aiming to improve patient outcomes and advance clinical management. This review offers a comprehensive overview of the metabolic mechanisms involved in calcific tendinopathy and shoulder arthrofibrosis, providing a foundation for future research and therapeutic development.

Ultrasound-guided percutaneous lavage for the treatment of rotator cuff calcific tendinopathy: a systematic review with meta-analysis of randomized controlled trials.

Ultrasound-guided lavage (UGL) is a minimally invasive percutaneous treatment for rotator cuff calcific tendinopathy (RCCT). It involves the use of a syringe containing saline and/or anesthetic solution injected directly into the calcification allowing aspiration of the fragmented calcific material. The aim of this systematic review is to investigate if UGL is effective in improving pain, function, quality of life, range of motion (ROM), and in promoting complete resorption of calcifications in patients with RCCT. Only randomized controlled trials considering people diagnosed with RCCT, at any stage and at any time of the onset of symptoms treated with UGL, were included. Embase, CENTRAL, CINHAL, PEDro and MEDLINE were explored up until May 2024. Two independent authors selected randomized controlled trials by title and abstract; afterwards, the full text was thoroughly evaluated. The risk of bias (ROB) was assessed using the Cochrane risk of bias 2 (ROB2) tool and the certainty of evidence was evaluated through the GRADE approach. Seven studies (709 subjects) were included. Overall, three studies were judged as low risk of bias. Pooled results showed non-significant differences between UGL and extracorporeal shock-wave therapy (ESWT) at 12 weeks (SMD=-0.52, 95% CI -1.57, 0.54, P=0.34, I2=93%) and at 26 weeks (MD=-1.20, 95% CI -2.66, 0.27, P=0.11, I2=82%), while a significant difference favoring UGL (SMD=-0.52, 95% CI -0.85, -0.19, P=0.002, I2=38%) resulted at 52 weeks. In regard to function, pooled results showed non-significant difference between UGL and ESWT at 6 weeks (MD=3.34, 95% CI -11.45, 18.12, P=0.66, I2=79%) and at 52 weeks (SMD=0.10, 95% CI -0.40, 0.60, P=0.69, I2=30%). Considering the rate of resorption of calcifications between UGL combined with subacromial corticosteroid injection (SCI) versus injection alone, pooled results showed significant difference favoring UGL at <52 weeks (RR=1.63 95% CI 1.34, 1.98, P<0.00001, I2=0%). Certainty of evidence ranged from low to very low. UGL seems to be a reasonable and safe treatment for RCCT, however compared to other non/mini-invasive approaches, UGL showed doubtful results in controlling pain and increasing function and rate of calcifications resorption. These results should be interpreted with caution because certainty of evidence ranged from low to very low.

Enhancing osteogenic differentiation of diabetic tendon stem/progenitor cells through hyperoxia: Unveiling ROS/HIF-1α signalling axis.

Diabetic calcific tendinopathy is the leading cause of chronic pain, mobility restriction, and tendon rupture in patients with diabetes. Tendon stem/progenitor cells (TSPCs) have been implicated in the development of diabetic calcified tendinopathy, but the molecular mechanisms remain unclear. This study found that diabetic tendons have a hyperoxic environment, characterized by increased oxygen delivery channels and carriers. In hyperoxic environment, TSPCs showed enhanced osteogenic differentiation and increased levels of reactive oxygen species (ROS). Additionally, hypoxia-inducible factor-1a (HIF-1a), a protein involved in regulating cellular responses to hyperoxia, was decreased in TSPCs by the ubiquitin-proteasome system. By intervening with antioxidant N-acetyl-L-cysteine (NAC) and overexpressing HIF-1a, we discovered that blocking the ROS/HIF-1a signalling axis significantly inhibited the osteogenic differentiation ability of TSPCs. Animal experiments further confirmed that hyperoxic environment could cause calcification in the Achilles tendon tissue of rats, while NAC intervention prevented calcification. These findings demonstrate that hyperoxia in diabetic tendons promotes osteogenic differentiation of TSPCs through the ROS/HIF-1a signalling axis. This study provides a new theoretical basis and research target for preventing and treating diabetic calcified tendinopathy.

Fibro-adhesive Bursitis: A Novel Sonographic Finding in Adhesive Capsulitis Patients and a Proposal of Management.

Adhesive capsulitis, also known as "frozen shoulder," is a debilitating shoulder condition increasingly linked to fibroadhesive bursitis, particularly after COVID-19 and related vaccinations. There is no definitive gold standard for its treatment, the primary therapeutic objectives of which are the reduction of pain and the restoration of shoulder range of motion. The aim of our study was to analyze treatment outcomes based on quantitative measures of shoulder function and symptom relief. Conducted between January 2022 and April 2023, the research involved 45 patients initially diagnosed with adhesive capsulitis and associated fibroadhesive bursitis. After excluding nine patients for other concomitant pathologies (five for calcific tendinopathy and four for rotator cuff injury), 36 patients were randomized into two groups: one group was treated with glenohumeral hydrodistension, the other with glenohumeral hydrodistension combined with bursal injection. Assessments were conducted at baseline and then 2, 4, and 6months after treatment, focusing on changes in pain levels, functional scores, and range of motion in all planes. Each group followed a home-based rehabilitation protocol. Significant improvements were observed in both treatment groups, with the combined hydrodistension and bursal injection group showing notably superior outcomes. Specifically, the range of motion in flexion improved from an initial median of 80° to 155° in the combined treatment group, compared to an increase from 75.5° to 129° in the group treated with hydrodistension alone. This enhancement was statistically significant (p < 0.001). Regarding pain reduction, the combined treatment group demonstrated a dramatic decrease in visual analogue scale (VAS) scores, from a baseline median of 7 to 1 at the 6-month follow-up. In contrast, the hydrodistension-only group showed a reduction from 7 to 3, with these differences also proving statistically significant (p < 0.001). Ultrasound-guided hydrodistension of the glenohumeral joint, if combined with bursal injection and specific exercises, effectively reduces pain, decreases disability, and improves range of motion in patients with second-stage adhesive capsulitis. This study highlights the importance of a combined approach in the management of this complex condition, especially after the histological changes that occurred after COVID-19 and related vaccinations.

The straight head of rectus femoris: An underdiagnosed cause of chronic pain post hip replacement

Groin pain following hip arthroplasty has a spectrum of aetiologies. Although mild post-operative pain at six months to a year is common, other causative factors should be considered where pain is severe or persistent. The rectus femoris (RF) muscle is the most common of the quadriceps tendons to be injured or strained. Pathologies are known to occur in athletic adults and children and include tendinopathy, tear, and avulsion, but the RF is rarely attributed to hip pain post-arthroplasty. However, tendinopathy may occur as a result of altered biomechanics and muscle loading. We performed a retrospective analysis of 100 patients, at our tertiary orthopedic hospital, who presented with chronic pain post hip arthroplasty. We identified three patients with RF straight (direct) head tendinopathy and one patient with RF straight (direct) head calcific tendinopathy. Established causes of chronic post-operative pain include septic/aseptic loosening, pseudotumor, iliopsoas bursitis/impingement, and bursitis. In this report, we describe the scanning technique, sonographic appearances, and our institutional experience of post-arthroplasty pathologies of the RF straight (direct) head which is an underreported cause of chronic pain following hip replacement. We also recommend including the RF straight (direct) head in routine US protocols of the post-operative hip.

The effectiveness of extracorporeal shock wave therapy for rotator cuff calcific tendinopathy. A systematic review with meta-analysis.

To investigate if Extracorporeal Shock Wave therapy (ESWT) is effective in reducing pain and disability, in improving function, quality of life and complete resorption rate of calcification in patients with Rotator Cuff Calcific Tendinopathy. To investigate which modality of ESWT brings the greatest clinical improvements between High (HE)-SWT and Low Energy (LE)-SWT and between Focal (F)-SWT and Radial (R)-SWT. MEDLINE, EMBASE, CENTRAL Database, and PEDro databases until February 2024 were searched. Study registers were further investigated. The Risk of Bias (RoB) was assessed with the Revised Cochrane RoB Tool (RoB 2). The certainty of evidence was rated with GRADE. Twenty-one randomized controlled trials were included. None was judged as overall low RoB. Comparing ESWT and Ultrasound Guided Needling Procedures (USGNP), the pooled results reported a significant difference favoring USGNP in pain at <24 and<48weeks (MD=1.17, p=0.004, I2=59%; MD=1.31, p=0.004, I2=42%, respectively). Comparing ESWT and sham-ESWT, the pooled results reported a clinically significant difference favoring ESWT in pain and function at 24weeks (MD=-5.72, p<0.00001, I2=0%; Standardized Mean Difference=2.94, p=0.02 I2=98%, respectively). Comparing HE-SWT and LE-SWT, HE-SWT was statistically and clinically superior in pain and function at <24weeks (MD=-1.83, p=0.03, I2=87%; MD=14.60, p=0.002, I2=77%, respectively) and showed a significantly higher complete resorption rate of calcification at 12weeks (Risk Ratio=2.53, p=0.001, I2=0%). F-SWT and R-SWT appear equally effective in reducing pain, improving disability and resorption rate. The certainty of evidence was rated as very low through GRADE approach. USGNP was statistically superior to ESWT in pain reduction at <24 and<48weeks. ESWT was clinically better to sham-ESWT in pain reduction and function improvement at 24weeks. HE-SWT was clinically more effective than LE-SWT in reducing pain, improving function at <24weeks, and resolving calcific deposits at 12weeks, while no differences between F-SWT and R-SWT were reported.

THERAPEUTIC OPTIONS IN CALCIFIC ROTATOR CUFF TENDINOPATHY OF THE SHOULDER

Calcific tendinopathy in the tendons of the rotator cuff muscles of the shoulder is an increasingly common and disabling pathology. Calcific tendinopathy is a common disease that mainly affects people aged between 40 and 60. Women seem to be more affected than men. It has been suggested that various factors play a role in the condition, such as abnormal thyroid gland activity, metabolic diseases (e.g. gout, diabetes) and genetic predisposition. Various aetiological hypotheses have been put forward: the degenerative and multiphasic theories are the two most widely accepted. Clinically, calcific tendonitis is characterised by severe, disabling pain, often occurring spontaneously, usually in the morning or following exertion disproportionate to subsequent symptoms. There may be concomitant stiffness, giving rise to a clinical picture resembling frozen shoulder or hyperalgesic painful shoulder. Conventional radiography of the shoulder is the most appropriate imaging approach, but perfectly complemented by soft tissue ultrasound. Most acute painful episodes resolve spontaneously symptomatically. Numerous conservative treatments have been reported in the literature with varying levels of evidence of efficacy. In the present study we tried to evaluate which therapeutic option could give superior results both from a functional, lesional architectural and causal point of view in terms of reduction of callus size, but also from an imaging point of view. The use of various therapeutic protocols have shown a significant benefit of the association of ESWT with conventional FKT, and intra-articular infiltration, with a plus for the association of Corticosteroids and Sodium Hyaluronate regarding the speed of achieving the desired results. Similar results were obtained with the intra-articular shoulder PRP technique, but with slower achievement of the desired results. Arthroscopic surgery is the orthopaedic specialist's last option.

Clinical features in rotator cuff calcific tendinopathy: A scoping review

Introduction The main goal of this scoping review is to highlight the clinical features of subjects with rotator cuff calcific tendinopathy (RCCT), in order to identify and map this condition clinical criteria, and thus to be able to hypothesize such pathology before imaging investigations. Methods Four databases were consulted up to January 2023. The obtained results were reported following the PRISMA-ScR and the Joanna Briggs Institute reviewer's manual was used as guideline for conducting the review. No time and geographical restrictions were applied. Results A total of 851 records have been identified, with 50 studies meeting the inclusion criteria. Subjects with RCCT mostly reported nightly, acute and severe pain with spontaneous onset. Symptoms were mostly unilateral. Subjects were mostly women aged between 30 and 60. Deficit in active and passive range of motion was reported, mainly during abduction and forward flexion. Endocrine and metabolic disorders were described as comorbidity, in particular diabetes and thyroid disorders. Conclusion In this scoping review, the most relevant RCCT clinical features were detected. These clinical criteria, predictive for shoulder RCCT, can be crucial to help all clinicians suspect this musculoskeletal disease early and with certainty, thus allowing for an appropriate and prompt diagnosis path. Level of evidence III.

Haglund resection versus Haglund non-resection for calcific insertional Achilles tendinopathy with Haglund deformity: A retrospective study

BackgroundCalcific insertional Achilles tendinopathy(CIAT) with Haglund deformity is a type of recalcitrant tendinopathy. The necessity of concomitant removal of Haglund deformity during CIAT treatment is controversial. The present study aimed to evaluate the functional outcomes between Haglund resection and Haglund non-resection in the treatment of CIAT with Haglund deformity. MethodsA retrospective study included 29 patients who were underwent Achilles tendon debridement, bursal excision, and subsequent tendon reattachment.for CIAT with Haglund deformity. All patients were divided into 2 groups according to Haglund resection (resection group, n = 16) and Haglund non-resection (non-resection group, n = 13) using the parallel line method on lateral calcaneal X ray after surgery. Patients were evaluated in terms of the American Orthopedic Foot and Ankle Society (AOFAS), Visual Analog Scale (VAS) and Victorian Institute of Sports Assessment–Achilles (VISA-A) scores and the mean time of activities of daily living (ADL). Anatomy changes included the Fowler-Philip angle, calcaneal pitch angle and Achilles tendon force arm were measured with radiography preoperatively and postoperatively. ResultsBoth groups exhibited a significant increase in AOFAS, VAS and VISA-A scores after surgery. There were no significant differences between the resection group and the non-resection group for the AOFAS (92.38 ± 5.7 vs. 93.15 ± 12.17; P = 0.82), VAS (0.5 ± 0.52 vs. 0.61 ± 0.87; P = 0.66) and VISA-A questionnaire (82.56 ± 13.46 vs. 74.92 ± 16.4; P = 0.18) at the latest follow-up. The mean time of ADL in the non-resection group was significantly faster compared to that of the resection group (8.15 ± 2.51 weeks vs. 11.31 ± 4.06 weeks, P = 0.02). The Fowler-Philip angle of the resection group decreased from 55.55° ± 12.34° preoperatively to 44.52° ± 10.24° at the latest follow-up (P = 0.001). The Fowler-Philip angle of the non-resection group decreased from 54.38° ± 8.41° preoperatively to 46.52° ± 8.02° at the latest follow-up (P = 0.016). The calcaneal pitch angle of the resection group increased from 22.76° ± 5.37° preoperatively to 25.98° ± 6. 4° at the latest follow-up (P = 0.018). The Achilles tendon force arm of the resection group decreased from 178.50 mm ± 5.37 mm preoperatively to 173.90 mm ± 8.07 mm at the latest follow-up (P = 0.018). ConclusionResection or non-resection of the posterosuperior calcaneal tuberosity for CIAT with Haglund deformity would both provide satisfactory functional outcomes. Haglund non-resection may expedite patients' return to their daily activities, suggesting a Haglund deformity resection may be unnecessary in the surgical treatment for CIAT with Haglund deformity.

Imaging of calcific tendinopathy: natural history, migration patterns, pitfalls, and management: a review.

Calcific tendinopathy is characterized by the deposition of calcium hydroxyapatite crystals in various tendons of the body. Terms like calcium tendinitis, tendinosis, and tendinopathy are used interchangeably. Calcific tendinopathy is a common and well-documented ailment in the literature. Although common, the natural history, aetiology, and progression of calcific tendinitis are poorly understood. The treatment options include conservative and interventional measures. However, these measures cannot be applied as a blanket and are often tailored depending on the stage/phase of the disease. Out of the recognized stages of the disease, the resorptive stage causes the utmost symptoms when the calcium is rather soft and unstable. During this stage, the calcium may migrate beyond expected resorption and get deposited in the adjacent tissues contiguous with the calcium focus. The common destinations include bursal migration, intraosseous migration, muscular migration, and other less common migration sites. Such atypical presentations can lead to dilemmas in the diagnosis, prolongation of the diagnostic pathway, unwarranted apprehension, and treatment delay. Radiologists' role in this situation is to correctly recognize the imaging findings of atypical presentations of calcific tendinopathy and prevent unnecessary diagnostic and interventional studies. In this review article, we describe the pathogenic pathway and natural history of calcific tendinopathy from a radiologist's perspective and discuss different migratory patterns of calcium in calcific tendinopathy not only around the shoulder but also in other areas of the body on different imaging modalities. We also show a few examples of mimics and pitfalls on imaging. Finally, we discuss the appropriate management option of this condition.

Extracorporeal Shock Wave Therapy in Calcifying Tendonitis of the Shoulder. Case Report

Calcific tendonitis in the shoulder is very common. Patients who do not improve with physical therapy treatment may benefit from shockwave treatment before an invasive procedure is indicated. The focused shockwave treatment has a high degree of recommendation in calcific tendonitis of the shoulder, according to several studies with a high level of evidence. This report shows a 58-year-old female patient with calcific tendonitis of the shoulder with pain for more than 6 months without response to medication and rehabilitation treatment. Four sessions of 3000 pulses were performed with a focused shockwave piezoelectric device, with a maximum level of energy of 0.4 mj/mm2. Pain remission and calcification resorption were verified 3 months after the last application. Extracorporeal Shockwave Treatment is a safe and effective alternative for calcific tendonitis of the shoulder. Keywords: ESWT, calcific tendinopathy, shoulder

Effectiveness of non-surgical management in rotator cuff calcific tendinopathy (the effect trial): protocol for a randomised clinical trial

IntroductionRotator cuff calcific tendinopathy (RCCT) involves calcific deposits in the rotator cuff. Non-surgical interventions such as extracorporeal shockwave therapy (ESWT) and ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT) are recommended...

US-guided percutaneous irrigation of extra-shoulder calcific tendinitis.

To investigate the efficacy and safety of ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT) applied out of the shoulder, comparing its effectiveness to US-PICT of the rotator cuff. Patients subjected to US-PICT for extra-shoulder calcific tendinitis (Case Group) were compared to those subjected to US-PICT of the rotator cuff (Control Group). We had pre-procedure Visual Analogue Scale (VAS) pain score, 1- and 3-month VAS of patients of the Case Group, pre-procedure and 3-month VAS of patients of the Control Group. The Case Group consisted of 41 patients (27 women; mean age: 45 ± 9years): 26 gluteus medius, 5 patellar tendon, 3 rectus femoris, 2 gluteus maximus, 2 common extensor tendon, 1 extensor carpi radialis longus, 1 pes anserinus, and 1 peroneus longus. The Control Group included 41 patients (27 women; mean age: 47 ± 11 years). The mean pre-procedure VAS of the Case Group was 8.8 ± 0.7 with a significant (P < .001) drop at 1 month (4.5 ± 0.6) and 3 months (3.6 ± 0.6). The mean pre-procedure VAS of the Control Group was 8 ± 1.4 and dropped to 3.1 ± 1.6 after 3 months (P < .001). Post-treatment VAS at 3 months was not significantly different between two Groups (P = 0.134). Similarly, the decrease of VAS from baseline to 3 months was not significantly different between the two Groups (P = 0.264). US-PICT is a safe and effective procedure that can be used out of the shoulder. This study demonstrated the safety and effectiveness of US-PICT as a valuable therapeutic option for extra-shoulder calcific tendinitis, with similar clinical outcome to the same procedure performed in the rotator cuff. The technique must be adapted in some deeply located calcifications by means of the use of different needles and by thoroughly planning the access point for the procedure.

Interobserver reliability of classifying shoulder calcific tendinopathy on plain radiography and ultrasound

Introduction: Shoulder calcific tendinopathy is a frequent cause of shoulder pain. Diagnosis is usually based on ultrasound (US) and/or x-ray. US is considered an inherently operator-dependent imaging modality and, interobserver variability has previously been described by experts in the musculoskeletal US. The main objective of this study is to assess the interobserver agreement for shoulder calcific tendinopathy attending to the size, type, and location of calcium analyzed in plain film and ultrasound among trained musculoskeletal radiologists.Material and methods: From June 2018 to May 2019, we conducted a prospective study. Patients diagnosed with shoulder pain related to calcific tendinopathy were included. Two different experienced musculoskeletal radiologists evaluated independently the plain film and the US.Results: Forty patients, with a mean age of 54.6 years, were included. Cohen´s kappa coefficient of 0.721 and 0.761 was obtained for the type of calcium encountered in plain film and the US, respectively. The location of calcification obtained a coefficient of 0.927 and 0.760 in plain film and US, respectively. The size of the calcification presented an intraclass correlation coefficient (ICC) of 0.891 and 0.86 in plain film and US respectively. No statistically significant differences were found in either measurement.Conclusion: This study shows very good interobserver reliability of type and size measurement (plain film and US) of shoulder calcifying tendinopathy in experienced musculoskeletal radiologists.Level of Evidence: III, prospective inter-observer study

Treatment of calcific tendinopathy of the rotator cuff with ultrasound-guided puncture and aspiration

ObjectiveCalcific tendinopathy of the rotator cuff is a common condition caused by the deposition of calcium crystals in the tendons of the rotator cuff. This study aimed to analyze the effectiveness of ultrasound-guided puncture and aspiration in calcific tendinopathy of the should in 86 patients treated at our center and to determine the factors associated with poor prognosis after this treatment. Material and methodsThis retrospective descriptive study included 86 patients with calcific tendinopathy of the rotator cuff treated with ultrasound-guided puncture and aspiration between 2015 and 2019 for whom clinical and radiological variables were collected 1, 3, 6, and 12 months after the procedure. ResultsOne year after treatment, 81.4% patients showed clinical improvement and 96.5% showed radiological improvement. Complications were observed in 34.9%; all complications were mild. ConclusionsUltrasound-guided puncture and aspiration is an effective treatment for calcific tendinopathy of the shoulder, resulting in a high rate of clinical and radiological improvement and a low rate of minor complications. This technique has additional advantages, such as interaction with the patient and the lack of ionizing radiation.
