Females Have Earlier Muscle Strength and Functional Recovery After Bridge-Enhanced Anterior Cruciate Ligament Repair.

Tissue Eng Part A 2020 Jun 25. Epub 2020 Jun 25.

Division of Sports Medicine, Department of Orthopaedic Surgery, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

While a sex effect on outcomes following anterior cruciate ligament (ACL) reconstruction surgery has been previously documented, less is known following bridge-enhanced ACL repair (BEAR). We hypothesized that female sex would have significantly worse early functional outcomes and higher retear rates following primary repair of the ACL enhanced with a tissue-engineered scaffold. Sixty-five patients (28 males and 37 females), age 14-35 with a complete ACL tear underwent primary repair of the ACL enhanced with a tissue-engineered scaffold (bridge-enhanced ACL repair) within 45 days of injury.

INTER-RATER AND TEST-RETEST RELIABILITY OF TWO NEW SINGLE LEG SIT-TO-STAND TESTS.

Int J Sports Phys Ther 2020 May;15(3):388-394

University of South Alabama, Department of Physical Therapy, Mobile, AL, USA.

Background: The single leg sit-to-stand test (SLSTST) is a functional test that assesses quadriceps strength. The original SLSTST was used to diagnose lumbar nerve root impingement/radiculopathy - specifically at the L3 and L4 level. The original SLSTST used one repetition as the requirement for a successful test, therefore it may not identify quadriceps weakness in highly functional individuals with or recovering from an athletic injury.

Ultra-High-Frame-Rate Ultrasound Monitoring of Muscle Contractility Changes Due to Neuromuscular Electrical Stimulation.

Ann Biomed Eng 2020 Jun 1. Epub 2020 Jun 1.

Department of Mechanical Engineering and Materials Science, University of Pittsburgh School of Engineering, Pittsburgh, PA, 15261, USA.

The quick onset of muscle fatigue is a critical issue when applying neuromuscular electrical stimulation (NMES) to generate muscle contractions for functional limb movements, which were lost/impaired due to a neurological disorder or an injury. For in situ assessment of the effect of NMES-induced muscle fatigue, a novel noninvasive sensor modality that can quantify the degraded contractility of a targeted muscle is required. In this study, instantaneous strain maps of a contracting muscle were derived from ultra-high-frame-rate (2 kHz) ultrasound images to quantify the contractility. Read More

Muscle contributions to tibiofemoral shear forces and valgus and rotational joint moments during single leg drop landing.

Scand J Med Sci Sports 2020 May 16. Epub 2020 May 16.

School of Behavioural and Health, Australian Catholic University, Melbourne, Vic, Australia.

Anterior cruciate ligament (ACL) injuries commonly occur during single-leg landing tasks and are a burdensome condition. Previous studies indicate that muscle forces play an important role in controlling ligamentous loading, yet these studies have typically used cadaveric models considering only the knee-spanning quadriceps, hamstrings, and gastrocnemius muscle groups. Any muscles (including non-knee-spanning muscles) capable of opposing the anterior shear joint reaction force and the valgus joint reaction moment are thought to have the greatest potential for protecting the ACL from injury.

Effects of Pulsed Radiofrequency on a Standard Model of Muscle Injury in Rats.

Anesth Pain Med 2020 Feb 4;10(1):e97372. Epub 2020 Feb 4.

Laboratory of Experimental Hepatology and Gastroenterology, Hospital de Clínicas de Porto Alegre (HCPA), Porto Alegre, Brazil.

Background: Pulsed radiofrequency (PRF) affects animal and plant tissues; however, the mechanism has not been defined. We hypothesized that the magnetic field produced by PRF exerts its effects by the magnetic sensitivity of transitions between spin states -a spin-correlated radical-pair mechanism (SCRPM)- which, in turn, affects the rates of chemical reactions with participation of paramagnetic species.

Objectives: This study aimed to evaluate the effects of PRF on redox equilibrium and inflammatory status in a standard model of muscle injury in rats. Read More

Passing return to sports tests after ACL reconstruction is associated with greater likelihood for return to sport but fail to identify second injury risk.

Knee 2020 Jun 1;27(3):949-957. Epub 2020 Apr 1.

University of Groningen, University Medical Center Groningen, Center for Human Movement Science, Antonius Deusinglaan 1, 9713 AV Groningen, the Netherlands; Exercise Science and Neuroscience, Department Exercise & Health, Faculty of Science, Paderborn University, Paderborn, Germany.

Background: A limited number of patients return to sport (RTS) after an anterior cruciate ligament reconstruction (ACLR) and patients who RTS have a relatively high risk for second ACL injury. The purpose of the current study was to compare the results of a test battery between patients who returned to the pre-injury level of sport (RTS group) and patients who did not (NO-RTS group). It was hypothesized that the RTS group showed better test results. Read More

Arthroscopy 2020 04;36(4):1202-1203

University of Virginia Health System.

Use of allograft/autograft hybrid hamstring anterior cruciate ligament grafts has gained popularity as a method to ensure appropriate graft diameter when autograft alone is insufficient. Several institutional series have been published with conflicting results. When there is any concern for autograft hamstring diameter, it is potentially better to consider other graft options.
