Anterior Cruciate Ligament Reconstruction Graft Options.

Anterior cruciate ligament reconstruction is one of the most common orthopaedic sports medicine surgeries. Its prevalence in the sports medicine sphere is matched by the numerous options of different techniques. Chief among these is graft selection, which most commonly falls into 1 of 4 options: bone-patellar tendon-bone (BPTB) autograft, hamstring tendon autograft (HT), quadriceps tendon autograft, and allografts.

Percutaneous repair of the Achilles tendon with one knot offers equivalent results as the same procedure with two knots. A comparative prospective study.

Purpose: The present prospective comparative study included patients with acute Achilles tendon rupture (ATR) who underwent percutaneous repair with one knot compared to percutaneous repair with two knots.

Methods: All patients underwent the procedure under local anesthesia. A total of 29 patients underwent percutaneous repair with two knots (Group A), and 33 patients underwent percutaneous repair with one knot (Group B).

Nanosphere hydrogel-mediated delivery of miR-34a-5p improves achilles tendon function in rat model.

Restoring motor function and preventing re-rupture and adhesion during Achilles tendon healing remain significant clinical challenges. Increasing evidence suggests that miRNA plays a crucial role in tendon healing and regeneration. The previously designed nanosphere hydrogel sustained-release system enables targeted, controlled release of drugs.

Correlation between MRI findings and functional outcomes in patients with calf muscle strain injuries: a retrospective study on 78 patients.

Background: Calf muscle strain injuries (CMSI), also known as "tennis leg," are frequently observed in middle-aged and physically active people, including non-professional athletes. While magnetic resonance imaging (MRI) is frequently used to assess the extent of these injuries, the relationship between MRI findings and long-term functional outcomes in non-athletic populations remains underexplored. This study aimed to investigate the correlation between MRI-detected injury severity and functional outcomes using the Achilles Tendon Rupture Score (ATRS) and the Tegner Activity Scale (TAS).

Achilles Tendon Ruptures in National Hockey League Players: Return to Sport and Performance Impact.

Background: Few studies assess rates of return to play and postinjury performance in National Hockey League (NHL) players who sustain Achilles tendon ruptures. Our objective was to determine the rate of return to play and performance impact among NHL players who undergo surgical repair of Achilles tendon tears.

Methods: NHL players who sustained an Achilles tendon rupture between 2001 and 2021 were identified using a publicly available injury database.

Neuromechanical adaptations in the gastrocnemius muscle after Achilles tendon rupture during walking.

Although some Achilles tendon rupture (ATR) patients regain function in low-force levels activities, it is not yet well known how neuromuscular and structural alterations after ATR manifest during everyday-locomotion. This study assessed medial gastrocnemius (MG) fascicle shortening during walking 1-year after ATR. Additionally, we explored neuromuscular alterations in lateral gastrocnemius (LG), soleus and flexor hallucis longus (FHL) muscles.

A Comparison of Achilles Tendon Morphological Characteristics Based Upon VISA-A Score in Active Adults Over Age 50.

Morphologic Achilles tendon properties obtained via diagnostic ultrasound imaging are valuable in understanding Achilles tendon health and injury. Currently, limited information exists regarding Achilles tendon morphological properties amongst active aging adults based upon Victorian Institute of Sport Assessment (VISA-A) scores. Achilles tendon morphologic properties defined by VISA-A score groupings allow clinicians and researchers to compare data values amongst current patients.

Dendritic Cell-Derived Exosomes Promote Tendon Healing and Regulate Macrophage Polarization in Preventing Tendinopathy.

Introduction: Tendon injuries present a significant challenge for independent repair, and can progress into tendinopathy over time, highlighting the importance of early intervention. Dendritic cell-derived exosomes (DEXs) has been shown to shift the polarization of M1 macrophages, the predominant inflammatory cells in the early stages of tendon injury. This study introduces a therapeutic approach that effectively manages inflammation while promoting regeneration in the treatment of tendinopathy.

Adhesion extent data of repaired rabbit Achilles tendons three weeks post-surgery and characterization data of different implant materials used for these surgeries.

As one major problem after tendon rupture repair, surgeons are confronted with fibrotic adhesion formation of the healing tendon to the surrounding tissue. Although early active motion is recommended during rehabilitation, adhesions may lead to joint stiffness and a restricted range of motion. One viable option to counteract adhesion formation is to add a thin elastic tube that is placed over the conventionally sutured repair site.
