Changes of Material Elastic Properties during Healing of Ruptured Achilles Tendons Measured with Shear Wave Elastography: A Pilot Study.

Int J Mol Sci 2020 May 12;21(10). Epub 2020 May 12.

Department of Trauma Surgery, University Medical Center Regensburg, Franz-Josef-Strauss-Allee 11, 93053 Regensburg, Germany.

Therapy options for ruptured Achilles tendons need to take into account the right balance of timing, amount and intensity of loading to ensure a sufficient biomechanical resilience of the healing tendon on the one hand, and to enable an adequate tensile stimulus on the other hand. However, biomechanical data of human Achilles tendons after rupture during the separate healing stages are unknown. Shear wave elastography is an ultrasound technique that measures material elastic properties non-invasively, and was proven to have a very good correlation to biomechanical studies. Read More

Does Early Functional Mobilization Affect Long-Term Outcomes After an Achilles Tendon Rupture? A Randomized Clinical Trial.

Orthop J Sports Med 2020 Mar 16;8(3):2325967120906522. Epub 2020 Mar 16.

Department of Molecular Medicine and Surgery, Karolinska Institutet, Stockholm, Sweden.

Background: Functional deficits and health-related impairments are common after an Achilles tendon rupture (ATR). Rehabilitation protocols vary greatly, and few studies have allowed loading in combination with ankle motion immediately after surgery (ie, early functional mobilization [EFM]). It is unclear whether EFM may counteract the negative impact of ankle immobilization after an ATR. Read More

Effect of testing temperature on the nanostructural response of tendon to tensile mechanical overload.

J Biomech 2020 May 2;104:109720. Epub 2020 Mar 2.

Division of Engineering, Saint Mary's University, Halifax, Canada; School of Biomedical Engineering, Dalhousie University, Halifax, Canada. Electronic address:

Despite many in vitro mechanical experiments of tendon being conducted at room temperature, few assessments have been made to determine how the structural response of tendon to mechanical overload may vary with ambient temperature. We explored whether damage to the collagen nanostructure of tendon resulting from tensile rupture varies with temperature. Use of bovine tail tendons in combination with NaBH crosslink stabilization treatment allowed us to probe the mechanisms underlying the observed changes. Read More

Surgical repair of acute Achilles tendon ruptures: a follow-up of 639 consecutive cases.

Eur J Orthop Surg Traumatol 2020 Jul 9;30(5):895-899. Epub 2020 Mar 9.

Unit of Orthopaedics, Department of Clinical Science and Education, Stockholm South General Hospital, Karolinska Institutet, Södersjukhuset, Stockholm, Sweden.

Background: Most studies on acute Achilles tendon rupture (AATR) and its treatment contain only a small number of patients, and due to selection criteria, older patients and those with comorbidities are typically excluded. Therefore, little is known about true complication rates in an unselected population reflecting the situation in an ordinary orthopedic department.

Method: Patient files of 639 consecutive Achilles tendon repairs in 631 patients with AATR between February 1998 and December 2005 were reviewed, and all complications from the day of surgery until December 2011 were identified using the hospital's patient records and the Swedish national registry.
