Sartorius muscle transfer for chronic quadriceps tendon rupture: A prospective study.

Background: Quadriceps tendon rupture (QTR) is an uncommon injury. In chronic QTR there may be a large defect and direct repair is not possible with sutures or transosseous anchors. There is no gold standard surgical procedure for the treatment of chronic QTR.

Chronic quadriceps tendon rupture: quadriceps tendon reconstruction using ipsilateral semitendinosus tendon graft.

Ruptures of the quadriceps tendon (QTRs) are uncommon. If the rupture is not diagnosed, chronic ruptures may develop. Re-ruptures of the quadriceps tendon are rare.

Minimally invasive excision and reconstruction of Achilles tendon xanthoma using free autologous semitendinosus tendon transfer: a surgical technique.

Background: Tendon xanthomatosis is often associated with familial hypercholesterolemia, but it can also occur in other medical conditions. The Achilles tendon is the most common site of tendon xanthomas. Reconstruction of large defects after the xanthoma excision, can be challenging.

Achilles Tendon Rupture and Dysmetabolic Diseases: A Multicentric, Epidemiologic Study.

Achilles tendon ruptures are common. Metabolic disorders, such as diabetes mellitus, hypercholesterolemia, thyroid disorders, and obesity, impair tendons health, leading to Achilles tendinopathy and likely predisposing patients to Achilles tendon ruptures. Patients who visited the Orthopedic Outpatient Clinics and the Accident and Emergency Departments of five different hospitals in Italy were recruited.

Elderly Runners and Osteoarthritis: A Systematic Review.

Purpose: The impact of running on the onset of osteoarthritis (OA) is controversial. This study compared the incidence of OA in elderly runners versus nonrunners.

Material And Methods: This systematic review was conducted according to the PRISMA guidelines.

Osteoarthritis in Athletes Versus Nonathletes: A Systematic Review.

Introduction: Joint overload and sport-related injuries may accelerate the development of osteoarthritis (OA). A systematic review of the literature was performed to establish the risk of athletes to develop premature OA compared with nonathletes.

Materials And Methods: This systematic review was conducted according to the PRISMA guidelines.

High Rates of Damage to the Medial Patellofemoral Ligament, Lateral Trochlea, and Patellar Crest After Acute Patellar Dislocation: Magnetic Resonance Imaging Analysis.

Purpose: The primary outcome of interest of this study was to determine the frequency, location, and extent of chondral injuries and medial patellofemoral ligament (MPFL) tears, along with the rate of loose bodies, in the knee after acute primary patellar dislocation. The secondary outcome of interest was to conduct a multivariate analysis to investigate whether the presence of pathoanatomic abnormalities, including structural differences in the knees of the patients, is associated with the features of the lesions.

Methods: Patients who underwent magnetic resonance imaging after primary acute patellar dislocation were identified from our institutional databases.

Chondral injuries in patients with recurrent patellar dislocation: a systematic review.

Background: Patellar dislocations in patients presenting with recurrent patellofemoral instability can damage the surrounding structures, limiting patient's participation to recreational activities and quality of life. This study evaluated frequency, location, and extent of associated injuries in patients with recurrent patellar dislocation.

Methods: This systematic review was conducted according to the PRISMA checklist.

Chondral and Soft Tissue Injuries Associated to Acute Patellar Dislocation: A Systematic Review.

Introduction: Chondral and soft tissue injuries can be associated with first time patellar dislocation, but it is unclear how common they are, and which tissues are affected. A systematic review of the literature was performed to investigate the frequency, location, and extent of chondral and medial patellofemoral ligament (MPFL) injuries in patients following first time patellar dislocation.

Methods: This systematic review was conducted according to the PRISMA guidelines.

The Impact of Hyaluronic Acid on Tendon Physiology and Its Clinical Application in Tendinopathies.

The physical-chemical, structural, hydrodynamic, and biological properties of hyaluronic acid within tendons are still poorly investigated. Medical history and clinical applications of hyaluronic acid for tendinopathies are still debated. In general, the properties of hyaluronic acid depend on several factors including molecular weight.

Complex ruptures of the quadriceps tendon: a systematic review of surgical procedures and outcomes.

Background: Chronic ruptures, ruptures following total knee arthroplasty (TKA), and re-ruptures of the quadriceps tendon (QT) are rare. A systematic review of the current literature was conducted on their treatment and outcome to provide evidence-based indications for their management.

Methods: We searched published articles in English on chronic ruptures of QT, QT ruptures that occurred after TKA, and re-ruptures in PubMed, Scopus, and Google Scholar up to January 2021.
