Perianchor Cyst Formation Is Similar Between All-Suture and Conventional Suture Anchors Used for Arthroscopic Rotator Cuff Repair in the Same Shoulder.

Arthrosc Sports Med Rehabil 2022 Jun 1;4(3):e949-e955. Epub 2022 Mar 1.

Department of Orthopaedic & Rehabilitation, Oregon Health & Science University, Portland, Oregon, U.S.A.

Purpose: The purpose of this study was to compare perianchor cyst formation between soft and hard suture anchors placed in the same patient 1 year after arthroscopic rotator cuff repair (ARCR).

Methods: This study reviewed patients who underwent primary ARCR using a "hybrid" technique using at least one soft anchor (FiberTak, Arthrex, Naples, FL) and one hard anchor (SwiveLock) placed in the same shoulder between January 1, 2018 and December 31, 2018. Magnetic resonance imaging was obtained at minimum 1-year postoperative to assess cyst formation (perianchor fluid signal) and rotator cuff healing. Read More

Treatment of Knee Osteochondral Fractures.

Healthcare (Basel) 2022 Jun 8;10(6). Epub 2022 Jun 8.

Department of Morphological Sciences, Carol Davila University of Medicine and Pharmacy, RO-020021 Bucharest, Romania.

Osteochondral lesions (OCLs) that are frequently encountered in skeletally immature and adult patients are more common than once thought, and their incidence rate is rising. These lesions can appear in many synovial joints of the body, such as the shoulder, elbow, hip, and ankle, occurring most often in the knee. The term osteochondral lesion includes a vast spectrum of pathologies such as osteochondritis dissecans, osteochondral defects, osteochondral fractures, and osteonecrosis of the subchondral bone.

Isolated Bioinductive Arthroscopic Repair of Partial-Thickness Rotator Cuff Tears Using a Resorbable Collagen Implant.

JBJS Essent Surg Tech 2022 Jan-Mar;12(1). Epub 2022 Jan 25.

Department of Trauma and Orthopaedic Surgery, University of Calgary, Calgary, Alberta, Canada.

Over 300,000 rotator cuff repairs are performed annually in the United States, where the annual financial burden of managing shoulder pain has been estimated to be $3 billion. Despite advances in surgical techniques, retear rates range from 39% to 94%. Partial-thickness tears are approximately twice as common as full-thickness tears and can lead to considerable pain and loss of function. Read More

Clinical Outcomes following Biologically Enhanced Demineralized Bone Matrix Augmentation of Complex Rotator Cuff Repair.

J Clin Med 2022 May 24;11(11). Epub 2022 May 24.

Department of Orthopedic Surgery, Technical University of Munich, 80333 Munich, Germany.

Complex rotator cuff tears provide a significant challenge for treating surgeons, given their high failure rate following repair and the associated morbidity. The purpose of this study is to evaluate the clinical outcomes of patients who underwent biologically enhanced demineralized bone matrix augmentation of rotator cuff repairs. Twenty patients with complex rotator cuff tears underwent arthroscopic rotator cuff repair by a single surgeon with demineralized bone matrix (DBM) augmentation that was biologically enhanced with platelet-rich plasma and concentrated bone marrow aspirate.

Prisma Health-Upstate Department of Emergency Medicine, Greenville, SC, United States of America. Electronic address:

As physicians attempt to "Choose Wisely" and decrease ionizing radiation, the use of Magnetic Resonance Imaging (MRI) has increased. While MRI does not expose patients to ionizing radiation, it does expose patients to specific risks, such as thermal burns. Unfortunately, obese patients are at the highest risk for MRI-related thermal burns. Read More

Central Commands to the Elbow and Shoulder Muscles During Circular Planar Movements of Hand With Simultaneous Generation of Tangential Forces.

Front Physiol 2022 19;13:864404. Epub 2022 May 19.

Institute of Traumatology and Orthopedics, National Academy of Medical Sciences of Ukraine, Kyiv, Ukraine.

This study examines some of the non-linear effects of signal transduction in the human motor system, with particular emphasis on muscle hysteresis. The movement tests were analyzed in a group of eight subjects, which were asked to develop tangential force using visual biofeedback while performing slow, externally imposed, circular movements of right hand holding a moving handle operated by a computerized mechatronic system. The positional changes in the averaged EMGs of the elbow and shoulder muscles were compared for all combinations of direction of movement and generated force. Read More

Authors:
Myung-Seo Kim

BMC Musculoskelet Disord 2022 Jun 4;23(1):532. Epub 2022 Jun 4.

Shoulder & Elbow Clinic, Department of Orthopaedic Surgery, College of Medicine, Kyung Hee University Hospital at Gangdong, 892, Dongnam-ro, Gangdong-gu, 05278, Seoul, Republic of Korea.

Background: Cases of rapidly destructive osteonecrosis (RDON) of the humeral head after arthroscopic rotator cuff repair (RCR) have rarely been reported, which has prevented a clear consensus on the cause of osteonecrosis.

Case Presentation: A 63-year-old woman without a history of trauma underwent arthroscopic RCR after being diagnosed with a medium-sized full-thickness rotator cuff tear for symptoms of left shoulder pain for six months. The patient had no medical history other than hypertension, and no other potential cause was found for osteonecrosis of the left shoulder prior to surgery. Read More

Posttreatment Changes of the Elbow.

Authors:
Thomas Grieser

Semin Musculoskelet Radiol 2022 Jun 2;26(3):271-294. Epub 2022 Jun 2.

Department of Diagnostic and Interventional Radiology, University Hospital Augsburg, Augsburg, Germany.

Radiologists should be familiar with the typical surgical procedures applied at the elbow and aware of the spectrum of normal and pathologic appearances of posttreatment situations throughout all radiologic modalities. Most important in the case of posttraumatic surgical elbow procedures is correct postoperative elbow joint alignment, appropriate fixation of joint-forming fragments, and proper insertion of screws, plates, and anchor devices that do not conflict with intra-articular or bony structures. To report soft tissue repair procedures correctly, radiologists need to know the broad spectrum of different techniques applied and their appearance on magnetic resonance imaging. Read More

Gel-Based Autologous Chondrocyte Implantation in a Patient with Noncontained Osteochondral Knee Defect at 9-Year Follow-Up.

Case Rep Orthop 2022 16;2022:6946860. Epub 2022 May 16.

Department of Orthopedics, Civil Hospital, Bhavnagar, Gujarat, India.

Osteochondritis dissecans (OCD) is a disorder of the subchondral bone affecting the adjacent articular cartilage that may lead to cartilage and bone fragment detachment. It commonly occurs in the knee joint, elbow, wrist, and ankle. Although several surgical concepts have been described to treat OCD (fragment fixation, microfracture, autologous chondrocyte implantation (ACI), and mosaicplasty), no gold standard treatment has been accepted for managing OCD.

Sports Health 2022 Jul-Aug;14(4):527-529. Epub 2022 May 12.

Department of Physical Medicine and Rehabilitation, College of Medicine, University of Florida, Gainesville, FL.

Ulnar collateral ligament (UCL) injuries of the elbow are common in throwing athletes. Given that the UCL's primary function is to provide valgus stability during the deceleration phase of throwing, injury to the UCL will render throwing difficult to nearly impossible. Injuries will occur more so in the sports of baseball, softball, and javlineers participating in track and field. Read More

Am J Sports Med 2022 Jun 10;50(7):1938-1947. Epub 2022 May 10.

Department of Orthopaedic Surgery, Yeosu Baek Hospital, Yeosu, Republic of Korea.

Background: Superior capsular reconstruction (SCR) and lower trapezius transfer (LTT) have recently been utilized to treat irreparable rotator cuff tears (IRCTs). There is still no clear guideline on which treatment method is a better fit for posterosuperior IRCTs with high-grade 4 fatty infiltration in the infraspinatus.

Optimization of machine learning method combined with brain-computer interface rehabilitation system.

J Phys Ther Sci 2022 May 1;34(5):379-385. Epub 2022 May 1.

Department of Information Engineering and Computer Science, Feng Chia University: No. 100, Sec. 1, Wenhwa Rd., Seatwen, Taichung city 407, Taiwan.

[Purpose] Stroke patients are unable to move on their own and must be rehabilitated to allow the nervous system to trigger and restore its function. Traditional practice is to use electrode caps to extract brain wave features and combine them with assistive devices. However, there are problems that the electrode cap is not easy to wear, and the potential recognition is not good, and different extraction methods will affect the accuracy of the Brain-Computer Interfaces (BCI), which still has room for improvement.
