The Copenhagen Achilles Length Measurement Performed at Time of Acute Achilles Tendon Rupture is Correlated to Tendon Elongation After 1 Year.

Elongation of the tendon has been proposed as the most important factor leading to poor outcome after acute Achilles tendon rupture (ATR). The aim of this paper was to investigate if Amlang's ultrasound classification (AmC) or the Copenhagen Achilles Length Measurement (CALM) when assessed in the acute phase after ATR could predict elongation 1 y after rupture. 107 males and 27 females, aged 18 to 70 y and treated nonsurgically were included.

Efficacy of high-volume injections with and without corticosteroid compared with sham for Achilles tendinopathy: a protocol for a randomised controlled trial.

Introduction: Achilles tendinopathy (AT) is a common and disabling musculoskeletal condition. First-line management involving Achilles tendon loading exercise with, or without, other modalities may not resolve the problem in up to 44% of cases. Many people receive injections.

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.

Investigating circadian clock gene expression in human tendon biopsies from acute exercise and immobilization studies.

Purpose: The discovery of musculoskeletal tissues, including muscle, tendons, and cartilage, as peripheral circadian clocks strongly implicates their role in tissue-specific homeostasis. Age-related dampening and misalignment of the tendon circadian rhythm and its outputs may be responsible for the decline in tendon homeostasis. It is unknown which entrainment signals are responsible for the synchronization of the tendon clock to the light-dark cycle.

[Tendinopathy in athletes].

Tendinopathy is a condition of tendon overuse and is a very common cause of morbidity among recreational and competitive athletes. Chronic overload results in degenerative changes of the tendon, which becomes painful and swollen with impaired function. A reduction in the overloading activity is the mainstay of the treatment.

Validity and reliability of an ultrasound measurement of the free length of the Achilles tendon.

Introduction: Valid length measurements of the different segments of the Achilles tendon are needed in order to investigate if differential elongation of the Achilles tendon takes place after rupture. The purpose of this paper was to present data concerning the accuracy and reliability of an ultrasound measurement of the free part of the Achilles tendon.

Methods: Both legs of 19 non-injured subjects were examined by magnetic resonance imagining (MRI) and ultrasound.

[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.

Does vitamin-D intake during resistance training improve the skeletal muscle hypertrophic and strength response in young and elderly men? - a randomized controlled trial.

Introduction: Recent studies have shown that vitamin-D intake can improve skeletal muscle function and strength in frail vitamin-D insufficient individuals. We investigated whether vitamin-D intake can improve the muscular response to resistance training in healthy young and elderly individuals, respectively.

Methods: Healthy untrained young (n = 20, age 20-30) and elderly (n = 20, age 60-75) men were randomized to 16 weeks of daily supplementary intake of either 48 μg of vitamin-D + 800 mg calcium (Vitamin-D-group) or 800 mg calcium (Placebo-group) during a period and at a latitude of low sunlight (December-April, 56°N).

Preserved skeletal muscle protein anabolic response to acute exercise and protein intake in well-treated rheumatoid arthritis patients.

Introduction: Rheumatoid arthritis (RA) is often associated with diminished muscle mass, reflecting an imbalance between protein synthesis and protein breakdown. To investigate the anabolic potential of both exercise and nutritional protein intake we investigated the muscle protein synthesis rate and anabolic signaling response in patients with RA compared to healthy controls.

Methods: Thirteen RA patients (age range 34-84 years; diagnosed for 1-32 years, median 8 years) were individually matched with 13 healthy controls for gender, age, BMI and activity level (CON).

Validation of a novel ultrasound measurement of achilles tendon length.

Purpose: A clinically applicable and accurate method for measuring Achilles tendon length is needed to investigate the influence of elongation of the Achilles tendon after acute rupture. The purpose of this study was to develop and validate an ultrasonographic (US) length measurement of the Achilles tendon-aponeurosis complex.

Methods: Both legs of 19 non-injured subjects were examined by magnetic resonance imaging (MRI) and US.

Treatment of acute Achilles tendon rupture in Scandinavia does not adhere to evidence-based guidelines: a cross-sectional questionnaire-based study of 138 departments.

The best treatment of acute Achilles tendon rupture has been discussed for decades. During the past half decade, evidence has increased in favor of nonoperative treatment and dynamic and weightbearing rehabilitation. We hypothesized that the treatment strategies would show great variation and that adherence to evidence-based recommendations would not be as good as desired.

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.

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.

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.
