Experimental Analysis of the Effect of Rehabilitation Intervention on Tennis Players by Joint Injury Treatment.

Biomed Res Int 2022 21;2022:4625719. Epub 2022 Jun 21.

Hebei University of Engineering, Handan, 056038 Heibei, China.

In the process of competition and training, tennis players often carry out explosive force and extreme centripetal and eccentric contraction, while the ligament and joint capsule on the shoulder joint are relatively weak, which also makes the joint often appear injury caused by overuse. It has been the direction of scientific research to help athletes recover their functions and return to the arena through effective rehabilitation training and prerehabilitation training. In this paper, the reliability and short-term effect of wearing dynamic and static shoulder joint brace after arthroscopic repair of rotator cuff injury were studied through a controlled trial of tennis exercise for the treatment of shoulder injury.

Drivers of Inpatient Hospitalization Costs, Joint-Specific Patient-Reported Outcomes, and Health-Related Quality of Life in Shoulder Arthroplasty for Cuff Tear Arthropathy.

J Shoulder Elbow Surg 2022 Jun 22. Epub 2022 Jun 22.

Department of Orthopaedics and Sports Medicine, University of Washington Medical Center, Seattle, WA, USA. Electronic address:

Background: Cuff tear arthropathy (CTA) can be successfully treated with various types of shoulder arthroplasty. While reverse total shoulder arthroplasty (RSA) is commonly used to treat CTA, CTA hemiarthroplasty (CTA-H, hemiarthroplasty with an extended humeral articular surface) can also be effective in patients with preserved glenohumeral elevation and an intact coracoacromial arch. As the value of arthroplasty is being increasingly scrutinized, cost containment has become a priority. Read More

Choosing Wisely: the lack of validity of ultrasound scans in the investigation of shoulder instability.

N Z Med J 2022 Feb 4;135(1549):92-100. Epub 2022 Feb 4.

For assistance in data collection and preparation of this manuscript.

Aim: To test the clinical validity and financial implications of the proposed Choosing Wisely statement: "Using ultrasound as a screening test for shoulder instability is inappropriate in people under 30 years of age, unless there is clinical suspicion of a rotator cuff tear."

Biomaterials and Regenerative Medicine in Pain Management.

Curr Pain Headache Rep 2022 Jun 21. Epub 2022 Jun 21.

Department of Biomedical Engineering, University of Houston Cullen College of Engineering, Houston, TX, USA.

Purpose Of Review: Pain presents a unique challenge due to the complexity of the biological pathways involved in the pain perception, the growing concern regarding the use of opioid analgesics, and the limited availability of optimal treatment options. The use of biomaterials and regenerative medicine in pain management is being actively explored and showing exciting progress in improving the efficacy of conventional pharmacotherapy and as novel non-pharmacological therapy for chronic pain caused by degenerative diseases. In this paper we review current clinical applications, and promising research in the use of biomaterials and regenerative medicine in pain management. Read More

Previous surgery for instability is a risk factor for a worse patient-reported outcome after anatomical shoulder arthroplasty for osteoarthritis: a Danish nationwide cohort study of 3,743 arthroplasties.

Acta Orthop 2022 Jun 21;93:588-592. Epub 2022 Jun 21.

Department of Orthopaedic Surgery, Herlev and Gentofte Hospital, and Department of Clinical Medicine, University of Copenhagen, Copenhagen, Denmark.

Background And Purpose: Although most patients have good outcomes after shoulder arthroplasty for osteoarthritis, certain risk factors may lead to disappointing outcomes. We assessed risk factors for a worse outcome after anatomical shoulder arthroplasty for osteoarthritis.
