Techniques for In Vivo Measurement of Ligament and Tendon Strain: A Review.
Techniques for In Vivo Measurement of Ligament and Tendon Strain: A Review. Ann Biomed Eng. 2020 Oct 06;: Authors: Zhang Q, Adam NC, Hosseini Nasab SH, Taylor WR, Smith CR Abstract The critical clinical and scientific insights achieved through knowledge of in vivo musculoskeletal soft tissue strains has motivated the development of relevant measurement techniques. This review provides a comprehensive summary of the key findings, limitations, and clinical impacts of these techniques to quantify musculoskeletal soft tissue strains during dynamic movements. Current technologies generally leverage three techniques to quantify in vivo strain patterns, including implantable strain sensors, virtual fibre elongation, and ultrasound. (1) Implantable strain sensors enable direct measurements of tissue strains with high accuracy and minimal artefact, but are highly invasive and current designs are not clinically viable. (2) The virtual fibre elongation method tracks the relative displacement of tissue attachments to measure strains in both deep and superficial tissues. However, the associated imaging techniques often require exposure to radiation, limit the activities that can be performed, and only quantify bone-to-bone tissue strains. (3) Ultrasound methods enable safe and non-invasive imaging of soft tissue deformation. However, ultrasound can only image superficial tissues, and measurements are confounded by out-of-plane tissue motion. Finally, all in vivo stra...
Conclusion: ACB preserves quadriceps motor strength while providing analgesia comparable to FNB in patients undergoing ACLR. However, patient satisfaction score is better with FNB than ACB.
Conditions: Rotator Cuff Repair; Anterior Cruciate Ligament Reconstruction With a Patella Autograph; Ankle Arthrodesis or Arthroplasty; Hallux Valgus Correction Interventions: Device: ACTIVE peripheral nerve stimulation with a percutaneously inserted lead and wearable stimulator (SPR Therapeutics, Cleveland, Ohio); Device: SHAM peripheral nerve stimulation with a percutaneously inserted lead and wearable SHAM stimulator (SPR Therapeutics, Cleveland, Ohio) Sponsors: University of California, San Diego; Uniformed Se...
In conclusion this paper provides a contemporary consensus on all studied features of the ALL. The findings warrant future research i n order to further test these early observations, with the ultimate goal of improving the long-term outcomes of ACL-injured patients.Level of evidence Level V —Expert opinion.
Conclusion After reconstruction of isolated ACL tears with a hamstring graft, FNB is not more effective than LIA on patients’ early postoperative pain. Patients who received a FNB consumed significantly less opioid-like analgesics. Level of evidence III – Prospective, comparative, non-randomized study.
There is considerable current interest in the role of the anterolateral ligament in persistent instability after anterior cruciate ligament reconstruction. The normal ligament may be identified using magnetic resonance imaging or ultrasound techniques. However, imaging evaluation of the ligament in vivo after injury requires further study to determine indications for repair or reconstruction.
