Hyaluronic Acid Versus Platelet-Rich Plasma for Chronic Tendinopathy and Enthesopathy

Chronic tendinopathies and enthesopathies are common musculoskeletal conditions in orthopedics and sports medicine, frequently leading to pain, impaired function, and significantly reduced quality of life. Their pathogenesis involves tissue degeneration and ineffective repair response, often without an active inflammatory process. Standard conservative management based on physiotherapy and activity modification is often prolonged and not always satisfactory. Minimally invasive injectable interventions supporting tendon and enthesis regeneration represent a promising alternative due to their favorable safety profile and outpatient feasibility. Hyaluronic acid (HA) is a glycosaminoglycan naturally present in connective tissues. In the context of tendinopathy, it is thought to modulate inflammatory processes, provide mechanical protection by reducing friction and adhesion within the tendon sheath, and support the proper organization of collagen fibers in the tendon matrix. Platelet-rich plasma (PRP) is an autologous concentrate of platelets providing high local concentrations of growth factors, including platelet-derived growth factor (PDGF), transforming growth factor beta (TGF-β), and vascular endothelial growth factor (VEGF), which initiate and support repair processes, cellular proliferation, and angiogenesis. This prospective, randomized, open-label, two-arm study aims to compare the clinical efficacy of hyaluronic acid (HA) and platelet-rich plasma (PRP) injections in 80 participants with chronic Achilles tendinopathy or medial epicondylopathy of the elbow. Participants will be randomly assigned in a 1:1 ratio to receive either two HA injections or two PRP injections administered two weeks apart under ultrasonographic guidance. Follow-up will continue for 12 months after the second injection. The primary outcomes are the changes from baseline to 6 months in pain intensity measured using a 100-millimeter (mm) Visual Analog Scale (VAS), upper-limb function measured using the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) questionnaire in participants with medial epicondylopathy, and Achilles tendon symptoms and function measured using the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire in participants with Achilles tendinopathy. The results will provide evidence to support the selection of injectable treatment for chronic tendinopathies and enthesopathies.

COMPARATIVE EFFECTS OF DRY NEEDLING AND NEURAL MOBILIZATION ON PAIN, STRENGTH AND RANGE OF MOTION IN PATIENTS WITH GOLFER'S ELBOW

This randomized clinical trial aims to compare the effectiveness of Dry Needling and Neural Mobilization in patients diagnosed with Golfer's Elbow (Medial Epicondylitis). The study will evaluate the effects of both interventions on pain intensity, grip strength, and range of motion. Participants will be randomly allocated to either the Dry Needling group or the Neural Mobilization group and treated over a specified intervention period. Outcome measures will be assessed at baseline and after treatment to determine which intervention provides greater improvement in pain reduction, muscle strength, and functional mobility. The results may contribute to evidence-based rehabilitation strategies for managing Golfer's Elbow

Telerehabilitation vs Supervised Physiotherapy for Medial Epicondylitis

This randomized controlled trial aims to compare the effectiveness of telerehabilitation and supervised physiotherapy in patients with medial epicondylitis. The primary outcome is improvement in pain and function using the Patient-Rated Elbow Evaluation (PREE). Secondary outcomes include pain intensity, grip strength, musculoskeletal ultrasound findings, adherence, and upper limb disability measured by Quick DASH.

Doxycycline for Elbow Tendinopathy

To evaluate the feasibility of subantimicrobial -dose (SD) doxycycline to improve outcomes of nonsurgical management of elbow tendinopathy via matrix metalloproteinase (MMP) inhibition as well as evaluate if participants will be compliant to with prescribed medication and exercise treatment. Our working hypothesis is that patients with elbow tendinopathy will be receptive to treatment with SD-doxycycline and compliant with the prescribed treatment.
