Effect of Platelet-Rich Plasma on Nonsurgically Treated Acute Achilles Tendon Ruptures: A Randomized, Double-Blinded Prospective Study.

Background: An acute Achilles tendon rupture (ATR) is a long-lasting and devastating injury. Possible biological augmentation to promote and strengthen tendon healing after an ATR would be desirable.

Purpose: To determine whether the application of a platelet-rich plasma (PRP) injection in nonsurgically treated ATRs may promote healing and thereby improve functional outcomes.

[Treatment of meniscal pathology].

The menisci play a major role in knee function regarding joint movement, stability, load distribution and load transmission. Injuries to the menisci cause pain, and meniscal tears are a common reason for patient referral. In Denmark, partial meniscectomy increased significantly until 2010, and several studies have questioned the long-term effect of meniscectomy as an overall procedure.

Effect of High-Volume Injection, Platelet-Rich Plasma, and Sham Treatment in Chronic Midportion Achilles Tendinopathy: A Randomized Double-Blinded Prospective Study.

Background: Injection therapies are often considered alongside exercise for chronic midportion Achilles tendinopathy (AT), although evidence of their efficacy is sparse.

Purpose: To determine whether eccentric training in combination with high-volume injection (HVI) or platelet-rich plasma (PRP) injections improves outcomes in AT.

Study Design: Randomized controlled trial; Level of evidence, 1.

Associations between abnormal ultrasound color Doppler measures and tendon pain symptoms in badminton players during a season: a prospective cohort study.

Background: Color Doppler ultrasound is widely used to examine intratendinous flow in individuals with overuse tendon problems, but the association between color Doppler and pain is still unclear.

Hypothesis: Intratendinous flow is present and associated with pain in badminton players, and intratendinous flow and pain increase during a badminton season.

Study Design: Cohort study (prognosis); Level of evidence, 2.

The navicular position test - a reliable measure of the navicular bone position during rest and loading.

Background: Lower limb injuries are a large problem in athletes. However, there is a paucity of knowledge on the relationship between alignment of the medial longitudinal arch (MLA) of the foot and development of such injuries. A reliable and valid test to quantify foot type is needed to be able to investigate the relationship between arch type and injury likelihood.

Evidence of accumulated stress in Achilles and anterior knee tendons in elite badminton players.

Tendon-related injuries are a major problem, but the aetiology of tendinopathies is unknown. In tendinopathies as well as during unaccustomed loading, intra-tendinous flow can be detected indicating that extensive loading can provoke intra-tendinous flow. The aim of present study is to evaluate the vascular response as indicated by colour Doppler (CD) activity in both the Achilles and patella tendon after loading during high-level badminton matches.

Colour doppler ultrasonography and sclerosing therapy in diagnosis and treatment of tendinopathy in horses-a research model for human medicine.

Sclerosing therapy has in recent studies showed promising results in patients with clinically and ultrasonographically diagnosed tendinosis in Achilles and patellar tendons. The aim of this investigation was to study the presence of intratendinous colour Doppler (CD) flow in horses with clinically diagnosed chronic tendinopathy and to test if experience from human studies could be extrapolated to horses. Special interest was focused on the treatment with sclerosing therapy and whether we could obtain the same successful peroperative findings as in humans.

Ultrasonographic investigation of the Achilles tendon in elite badminton players using color Doppler.

Background: The most frequent injuries in badminton players are in the lower extremities, especially in the Achilles tendon.

Hypothesis: The game of badminton may be related to abnormal intratendinous flow in the Achilles tendon as detected by color Doppler ultrasound. To a certain extent, this blood flow might be physiological, especially when examined after match.
